GENERAL DESCRIPTION
The AD5601/AD5611/AD5621, members of the nanoDAC®
family, are single, 8-/10-/12-bit, buffered voltage output DACs
that operate from a single 2.7 V to 5.5 V supply, consuming
typically 75 µA at 5 V. The parts come in tiny LFCSP and SC70
packages. Their on-chip precision output amplifier allows railto-rail output swing to be achieved. The AD5601/AD5611/
AD5621 utilize a versatile 3-wire serial interface that operates at
clock rates up to 30 MHz and is compatible with SPI, QSPI™,
MICROWIRE™, and DSP interface standards.
The reference for the AD5601/AD5611/AD5621 is derived
from the power supply inputs and, therefore, gives the widest
dynamic output range. The parts incorporate a power-on reset
circuit, which ensures that the DAC output powers up to 0 V
and remains there until a valid write to the device takes place.
The AD5601/AD5611/AD5621 contain a power-down feature
that reduces current consumption to typically 0.2 µA at 3 V.

Description
2.7 V to 5.5 V, <100 µA, 14-bit nanoDAC in
SC70 and LFCSP packages
They also provide software-selectable output loads while in
power-down mode. The parts are put into power-down mode
over the serial interface.
The low power consumption of these parts in normal operation
makes them ideally suited to portable battery-operated equipment. The combination of small package and low power makes
these nanoDAC devices ideal for level-setting requirements,
such as generating bias or control voltages in space-constrained
and power-sensitive applications.

Low power, single-supply operation. The AD5601/
AD5611/AD5621 operate from a single 2.7 V to 5.5 V
supply with a maximum current consumption of 100 µA,
making them ideal for battery-powered applications.
The on-chip output buffer amplifier allows the output of
the DAC to swing rail-to-rail with a typical slew rate of
0.5 V/µs.
Reference is derived from the power supply.
High speed serial interface with clock speeds up to
30 MHz. Designed for very low power consumption.
The interface powers up only during a write cycle.
Power-down capability. When powered down, the DAC
typically consumes 0.2 µA at 3 V. Power-on reset with
brownout detection.

Description
Level-Triggered Control Input (Active Low). This is the frame synchronization signal for the input
data. When SYNC goes low, it enables the input shift register, and data is transferred in on the falling
edges of the clocks that follow. The DAC is updated following the 16th clock cycle, unless SYNC is
taken high before this edge, in which case the rising edge of SYNC acts as an interrupt and the write
sequence is ignored by the DAC.
Serial Clock Input. Data is clocked into the input shift register on the falling edge of the serial clock
input. Data can be transferred at rates up to 30 MHz.
Serial Data Input. This device has a 16-bit shift register. Data is clocked into the register on the falling
edge of the serial clock input.
Power Supply Input. The AD5601/AD5611/AD5621 can be operated from 2.7 V to 5.5 V. VDD should be
decoupled to GND.
Ground. Ground reference point for all circuitry on the AD5601/AD5611/AD5621.
Analog Output Voltage from the DAC. The output amplifier has rail-to-rail operation.
Exposed Pad. Connect to GND.

TERMINOLOGY
Relative Accuracy
For the DAC, relative accuracy or integral nonlinearity (INL) is
a measure of the maximum deviation, in LSBs, from a straight
line passing through the endpoints of the DAC transfer function. See Figure 5 to Figure 7 for plots of typical INL vs. code.
Differential Nonlinearity
Differential nonlinearity (DNL) is the difference between the
measured change and the ideal 1 LSB change between any two
adjacent codes. A specified differential nonlinearity of ±1 LSB
maximum ensures monotonicity. This DAC is guaranteed
monotonic by design. See Figure 11 to Figure 13 for plots of
typical DNL vs. code.
Zero-Code Error
Zero-code error is a measure of the output error when zero
code (0x0000) is loaded to the DAC register. Ideally, the output
should be 0 V. The zero-code error is always positive in the
AD5601/AD5611/AD5621 because the output of the DAC cannot
go below 0 V. Zero-code error is due to a combination of the
offset errors in the DAC and output amplifier. Zero-code error
is expressed in mV. See Figure 28 for a plot of zero-code error
vs. temperature.
Full-Scale Error
Full-scale error is a measure of the output error when full-scale
code (0xFFFF) is loaded to the DAC register. Ideally, the output
should be VDD − 1 LSB. Full-scale error is expressed in mV. See
Figure 28 for a plot of full-scale error vs. temperature.
Total Unadjusted Error
Total unadjusted error (TUE) is a measure of the output error,
taking all the various errors into account. See Figure 8 to
Figure 10 for plots of typical TUE vs. code.
Zero-Code Error Drift
Zero-code error drift is a measure of the change in zero-code
error with a change in temperature. It is expressed in µV/°C.
Gain Temperature Coefficient
Gain temperature coefficient is a measure of the change in gain
error with changes in temperature. It is expressed in (ppm of
full-scale range)/°C.
Digital-to-Analog Glitch Impulse
Digital-to-analog glitch impulse is the impulse injected into the
analog output when the input code in the DAC register changes
state. It is normally specified as the area of the glitch in nV-s
and is measured when the digital input code is changed by
1 LSB at the major carry transition (0x2000 to 0x1FFF). See
Figure 19.
Digital Feedthrough
Digital feedthrough is a measure of the impulse injected into
the analog output of the DAC from the digital inputs of the
DAC, but is measured when the DAC output is not updated.
It is specified in nV-s and is measured with a full-scale code
change on the data bus—from all 0s to all 1s and vice versa.
Gain Error
Gain error is a measure of the span error of the DAC. It is the
deviation in slope of the DAC transfer characteristic from the
ideal, expressed as a percent of the full-scale range.

THEORY OF OPERATION
DAC SECTION
OUTPUT AMPLIFIER
The AD5601/AD5611/AD5621 DACs are fabricated on a
CMOS process. The architecture consists of a string DAC
followed by an output buffer amplifier. Figure 39 is a block
diagram of the DAC architecture.
The output buffer amplifier is capable of generating rail-to-rail
voltages on its output, giving an output range of 0 V to VDD. It is
capable of driving a load of 2 kΩ in parallel with 1000 pF to
GND. The source and sink capabilities of the output amplifier
are shown in Figure 25. The slew rate is 0.5 V/µs, with a halfscale settling time of 8 µs with the output loaded.

Because the input coding to the DAC is straight binary, the ideal
output voltage is given by
D
VOUT = VDD ×  n 
2 
where:
D is the decimal equivalent of the binary code that is loaded to
the DAC register.
n is the bit resolution of the DAC.
RESISTOR STRING
The resistor string structure is shown in Figure 40. It is simply a
string of resistors, each of Value R. The code loaded to the DAC
register determines at which node on the string the voltage is
tapped off to be fed into the output amplifier. The voltage is
tapped off by closing one of the switches connecting the string
to the amplifier. Because it is a string of resistors, it is guaranteed monotonic.

The AD5601/AD5611/AD5621 have a 3-wire serial interface
(SYNC, SCLK, and SDIN) that is compatible with SPI, QSPI,
and MICROWIRE interface standards as well as most DSPs. See
Figure 2 for a timing diagram of a typical write sequence.
The write sequence begins by bringing the SYNC line low. Data
from the SDIN line is clocked into the 16-bit shift register on
the falling edge of SCLK. The serial clock frequency can be as
high as 30 MHz, making the AD5601/AD5611/AD5621 compatible with high speed DSPs. On the 16th falling clock edge,
the last data bit is clocked in and the programmed function is
executed (a change in DAC register contents and/or a change
in the mode of operation). At this stage, the SYNC line may be
kept low or brought high. In either case, it must be brought high
for a minimum of 33 ns before the next write sequence so that a
falling edge of SYNC can initiate the next write sequence.
Because the SYNC buffer draws more current when VIN = 1.8 V
than it does when VIN = 0.8 V, SYNC should be idled low
between write sequences for even lower power operation of the
part, as mentioned previously. However, it must be brought
high again just before the next write sequence.
INPUT SHIFT REGISTER
The input shift register is 16 bits wide (see Figure 41). The first
two bits are control bits, which control the operating mode of
the part (normal mode or any one of three power-down
modes). For a complete description of the various modes, see
the Power-Down Modes section. For the AD5621, the next
12 bits are the data bits, which are transferred to the DAC
register on the 16th falling edge of SCLK. The information in
the last two bits is ignored by the AD5621. See Figure 42 and
Figure 43 for the AD5611 and AD5601 input shift register map.
SYNC INTERRUPT
R
06853-039
R
In a normal write sequence, the SYNC line is kept low for at
least 16 falling edges of SCLK and the DAC is updated on the
16th falling edge. However, if SYNC is brought high before the
16th falling edge, this acts as an interrupt to the write sequence.
The shift register is reset and the write sequence is seen as
invalid. Neither an update of the DAC register contents nor a
change in the operating mode occurs (see Figure 44).

POWER-ON RESET
MICROPROCESSOR INTERFACING
The AD5601/AD5611/AD5621 contain a power-on reset circuit
that controls the output voltage during power-up. The DAC
register is filled with 0s and the output voltage is 0 V. It remains
there until a valid write sequence is made to the DAC. This is
useful in applications in which it is important to know the state
of the DAC output while it is in the process of powering up.
AD5601/AD5611/AD5621 to ADSP-2101 Interface
The AD5601/AD5611/AD5621 have four separate modes of
operation. These modes are software-programmable by setting
two bits (DB15 and DB14) in the control register. Table 6 shows
how the state of the bits corresponds to the operating mode of
the device.

There are three different options: the output is connected
internally to GND through a 1 kΩ resistor or a 100 kΩ resistor,
or the output is left open-circuited (three-stated). Figure 45
shows the output stage.
Figure 47 shows a serial interface between the AD5601/AD5611/
AD5621 and the 68HC11/68L11 microcontroller. SCK of the
68HC11/68L11 drives the SCLK of the AD5601/AD5611/
AD5621, while the MOSI output drives the serial data line of
the DAC. The SYNC signal is derived from a port line (PC7).
The setup conditions for correct operation of this interface are
as follows: the 68HC11/68L11 should be configured so that the
CPOL bit is 0 and the CPHA bit is 1. When data is being transmitted to the DAC, the SYNC line is taken low (PC7). When the
68HC11/68L11 are configured as indicated, data appearing on
the MOSI output is valid on the falling edge of SCK. Serial data
from the 68HC11/68L11 is transmitted in 8-bit bytes with only
eight falling clock edges occurring in the transmit cycle. Data is
transmitted MSB first. To load data to the AD5601/AD5611/
AD5621, PC7 is left low after the first eight bits are transferred
and a second serial write operation is performed to the DAC.
PC7 is taken high at the end of this procedure.

Not only does the supply current fall, but the output stage is
also internally switched from the output of the amplifier to a
resistor network of known values. This has the advantage that
the output impedance of the part is known while the part is in
power-down mode.

When both bits are set to 0, the part has normal power

0.2 µA at 3 V.

The bias generator, output amplifier, resistor string, and other
associated linear circuitry are all shut down when power-down

are unaffected when in power-down. The time to exit powerdown is typically 13 µs for VDD = 5 V and 16 µs for VDD = 3 V.

be set up to operate in SPORT transmit alternate framing mode.
The ADSP-2101 SPORT is programmed through the SPORT
control register and should be configured as follows: internal
clock operation, active low framing, and 16-bit word length.
Transmission is initiated by writing a word to the Tx register
after the SPORT is enabled.

ADSP-BF53x processor family incorporates two dual-channel
synchronous serial ports, SPORT1 and SPORT0, for serial and
multiprocessor communications. Using SPORT0 to connect to
the AD5601/AD5611/AD5621, the setup for the interface is as
follows: DT0PRI drives the SDIN pin of the AD5601/AD5611/

drives the serial data line of the part. The SYNC signal is again
derived from a bit programmable pin on the port. In this case,
Port Line P3.3 is used. When data is to be transmitted to the

transmit data only in 8-bit bytes; therefore, only eight falling
clock edges occur in the transmit cycle. To load data to the
DAC, P3.3 is left low after the first eight bits are transmitted,
Figure 50 shows an interface between the AD5601/AD5611/
AD5621 and any MICROWIRE-compatible device. Serial data
is shifted out on the falling edge of the serial clock and is
clocked into the AD5601/AD5611/AD5621 on the rising edge
of the SK.

and a second write cycle is initiated to transmit the second byte
of data. P3.3 is taken high following the completion of this
cycle. The 80C51/80L51 output the serial data LSB first. The
AD5601/AD5611/AD5621 require data with the MSB as the
first bit received. The 80C51/80L51 transmit routine should
take this into account.

APPLICATIONS
CHOOSING A REFERENCE AS POWER SUPPLY FOR

BIPOLAR OPERATION USING THE
AD5601/AD5611/AD5621
The AD5601/AD5611/AD5621 come in tiny LFCSP and SC70
packages with less than a 100 µA supply current. Because of
this, the choice of reference depends on the application
requirements. For applications with space-saving requirements,
the ADR02 is recommended. It is available in an SC70 package
and has excellent drift at 9 ppm/°C (3 ppm/°C in the R-8 package)
and provides very good noise performance at 3.4 µV p-p in the 0.1
Hz to 10 Hz range.
The AD5601/AD5611/AD5621 have been designed for singlesupply operation, but a bipolar output range is also possible
using the circuit shown in Figure 52. The circuit in Figure 52
gives an output voltage range of ±5 V. Rail-to-rail operation at
the amplifier output is achievable using an AD820 or OP295 as
the output amplifier.

Because the supply current required by the AD5601/AD5611/
AD5621 is extremely low, the parts are ideal for low supply
applications. The ADR395 voltage reference is recommended in
this case. It requires less than 100 µA of quiescent current and
can, therefore, drive multiple DACs in one system, if required. It
also provides very good noise performance at 8 µV p-p in the
0.1 Hz to 10 Hz range.

USING THE AD5601/AD5611/AD5621 WITH A
GALVANICALLY ISOLATED INTERFACE
POWER SUPPLY BYPASSING AND GROUNDING
In process control applications in industrial environments,
it is often necessary to use a galvanically isolated interface to
protect and isolate the controlling circuitry from any hazardous
common-mode voltages that might occur in the area where the
DAC is functioning. iCoupler® provides isolation in excess of
2.5 kV. Because the AD5601/AD5611/AD5621 use a 3-wire serial
logic interface, the ADuM1300 3-channel digital isolator
provides the required isolation (see Figure 53). The power
supply to the part also needs to be isolated, which is done by
using a transformer. On the DAC side of the transformer, a 5 V
regulator provides the 5 V supply required for the AD5601/
AD5611/AD5621.

When accuracy is important in a circuit, it is helpful to carefully
consider the power supply and ground return layout on the
board. The PCB containing the AD5601/AD5611/AD5621
should have separate analog and digital sections, each having its
own area of the board. If the AD5601/AD5611/AD5621 are in a
system where other devices require an AGND-to-DGND
connection, the connection should be made at one point only.
This ground point should be as close as possible to the
AD5601/AD5611/AD5621.
The power supply to the AD5601/AD5611/AD5621 should be
bypassed with 10 µF and 0.1 µF capacitors. The capacitors
should be physically as close as possible to the device, with the
0.1 µF capacitor ideally right up against the device. The 10 µF
capacitors are the tantalum bead type. It is important that the
0.1 µF capacitor have low effective series resistance (ESR) and
effective series inductance (ESI), such as in common ceramic
types of capacitors. This 0.1 µF capacitor provides a low impedance path to ground for high frequencies caused by transient
currents due to internal logic switching.
The power supply line itself should have as large a trace as
possible to provide a low impedance path and reduce glitch
effects on the supply line. Clocks and other fast switching
digital signals should be shielded from other parts of the board
by digital ground. Avoid crossover of digital and analog signals,
if possible. When traces cross on opposite sides of the board,
ensure that they run at right angles to each other to reduce
feedthrough effects on the board. The best board layout technique is the microstrip technique, where the component side of
the board is dedicated to the ground plane only and the signal
traces are placed on the solder side. However, this is not always
possible with a two-layer board.
