DESCRIPTION
The TLV5614IYZ is a quadruple, 12-bit, voltage output digital-to-analog converter (DAC) with a flexible 4-wire
serial interface. The serial interface allows glueless interface to TMS320, SPI, QSPI, and Microwire serial ports.
The TLV5614IYZ is programmed with a 16-bit serial word comprised of a DAC address, individual DAC control
bits, and a 12-bit DAC value. The device has provision for two supplies: one digital supply for the serial interface
(via pins DVDD and DGND), and one for the DACs, reference buffers, and output buffers (via pins AVDD and
AGND). Each supply is independent of the other, and can be any value between 2.7V and 5.5V. The dual
supplies allow a typical application where the DAC is controlled via a microprocessor operating on a 3V supply
(also used on pins DVDD and DGND) with the DACs operating on a 5V supply. Of course, the digital and analog
supplies can also be tied together.
The resistor string output voltage is buffered by a 2x gain rail-to-rail output buffer. The buffer features a
Class-AB output stage to improve stability and reduce settling time. A rail-to-rail output stage and a power-down
mode makes it ideal for single voltage, battery-based applications. The DAC settling time is programmable,
allowing the designer to optimize speed versus power dissipation. Settling time is chosen by the control bits
within the 16-bit serial input string. A high-impedance buffer is integrated on the REFINAB and REFINCD
terminals to reduce the need for a low source impedance drive to the terminal. REFINAB and REFINCD allow
DACs A and B to have a different reference voltage than DACs C and D.
The TLV5614IYZ is built with a CMOS process and is available in a 16-terminal bumped die (wafer chip scale)
package. It is characterized for operation from –40°C to +85°C in a wire-bonded, small outline (SOIC) package.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be
more susceptible to damage because very small parametric changes could cause the device not to meet its published
specifications.

(1)
The relative accuracy or integral nonlinearity (INL), sometimes referred to as linearity error, is the maximum deviation of the output from
the line between zero and full-scale excluding the effects of zero code and full-scale errors.
(2) The differential nonlinearity (DNL), sometimes referred to as differential error, is the difference between the measured and ideal 1 LSB
amplitude change of any two adjacent codes. Monotonic means the output voltage changes in the same direction (or remains constant)
as a change in the digital input code.
(3) Zero-scale error is the deviation from zero voltage output when the digital input code is zero.
(4) Zero-scale error temperature coefficient is given by: EZS TC = [EZS (TMAX) – EZS (TMIN)]/VREF × 106/(TMAX – TMIN).
(5) Gain error is the deviation from the ideal output (2VREF – 1 LSB) with an output load of 10 kΩ excluding the effects of the zero error.
(6) Gain temperature coefficient is given by: EG TC = [EG(TMAX) – EG (TMIN)]/VREF × 106/(TMAX – TMIN).
(7) Zero-scale error rejection ratio (EZS–RR) is measured by varying the AVDD from 5V ± 0.5V and 3V ± 0.3VDC, and measuring the
proportion of this signal imposed on the zero-code output voltage.
(8) Full-scale rejection ratio (EG–RR) is measured by varying the AVDD from 5V ± 0.5V and 3V ± 0.3VDC and measuring the proportion of
this signal imposed on the full-scale output voltage after subtracting the zero scale change.
(9) Reference input voltages greater than VDD/2 cause output saturation for upper DAC codes.
(10) Reference feedthrough is measured at the DAC output with an input code = 000hex and VREF (REFINAB or REFINCD) input =
1.024VDC + 1VPP at 1kHz.

SBAS401 – DECEMBER 2006
APPLICATION INFORMATION
GENERAL FUNCTION
The TLV5614IYZ is a 12-bit, single-supply DAC based on a resistor string architecture. The device consists of a
serial interface, speed and power-down control logic, a reference input buffer, a resistor string, and a rail-to-rail
output buffer.
The output voltage (full-scale determined by external reference) is given by:
2 REF CODE
[V]
2n
where REF is the reference voltage and CODE is the digital input value within the range of 010 to (2n – 1), where
n = 12 (bits). The 16-bit data word, consisting of control bits and the new DAC value, is described in the data
format section. A power-on reset initially resets the internal latches to a defined state (all bits '0').
SERIAL INTERFACE
Data transfer occurs in this manner: First, the device must be enabled with CS set low. Then, a falling edge of
FS starts shifting the data bit-per-bit (starting with the MSB) to the internal register on the falling edges of SCLK.
After 16 bits have been transferred or FS rises, the content of the shift register is moved to the DAC latch, which
then updates the voltage output to the new level.
The serial interface of the TLV5614IYZ can be used in two basic modes:
• Four-wire (with chip-select)
• Three-wire (without chip-select)
Using chip-select (four-wire mode), it is possible to have more than one device connected to the serial port of
the data source (a DSP or microcontroller). The interface is compatible with the TMS320 DSP family. Figure 15
shows an example with two TLV5614IYZs connected directly to a TMS320 DSP.

If there is no need to have more than one device on the serial bus, then CS can be tied low. Figure 16 shows an
example of how to connect the TLV5614IYZ to a TMS320, SPI, or Microwire port using only three pins.

APPLICATION INFORMATION (continued)
Notes on SPI and Microwire connections: Before the controller starts the data transfer, the software must
generate a falling edge on the I/O pin connected to FS. If the word width is eight bits (SPI and Microwire), two
write operations must be performed to program the TLV5614IYZ. After the write operation(s), the DAC output is
updated automatically on the next positive clock edge following the 16th falling clock edge.
SERIAL CLOCK FREQUENCY AND UPDATE RATE
The maximum serial clock frequency is given by:
1
fSCLKmax =
= 20 MHz
twH(min) + twL(min)
The maximum update rate is:
1
fUPDATEmax =

Note that the maximum update rate is a theoretical value for the serial interface, because the settling time of the
TLV5614IYZ must also be considered.

TLV5614IYZ INTERFACED TO TMS320C203 DSP
Hardware Interfacing
Figure 17 shows an example of how to connect the TLV5614IYZ to a TMS320C203 DSP. The serial port is
configured in burst mode, with FSX generated by the TMS320C203 to provide the frame sync (FS) input to the
TLV5614IYZ. Data is transmitted on the DX line, with the serial clock input on the CLKX line. The
general-purpose input/output port bits IO0 and IO1 are used to generate the chip select (CS) and DAC latch
update (LDAC) inputs to the TLV5614IYZ. The active low power-down (PD) is pulled high all the time to ensure
the DACs are enabled.

Software
The application example outputs a differential in-phase (sine) signal between the VOUTA and VOUTB pins, and
its quadrature (cosine) signal as the differential signal between VOUTC and VOUTD.
The on-chip timer is used to generate interrupts at a fixed frequency. The related interrupt service routine pulses
LDAC low to update all four DACs simultaneously, then fetches and writes the next sample to all four DACs. The
samples are stored in a look-up table that describes two full periods of a sine wave.
The synchronous serial port of the DSP is used in burst mode. In this mode, the processor generates an FS
pulse preceding the MSB of every data word. If multiple, contiguous words are transmitted, a violation of the
tsu(C16–FS) timing requirement occurs. To avoid this violation, the program waits until the transmission of the
previous word has been completed.

; Processor: TMS320C203 runnning at 40 MHz
;
; Description:
;
; This program generates a differential in-phase (sine) on (OUTA-OUTB) and its quadrature
(cosine) as a differential signal on (OUTC-OUTD).
;
; The DAC codes for the signal samples are stored as a table of 64 12-bit values, describing
; 2 periods of a sine function. A rolling pointer is used to address the table location in
; the first period of this waveform, from which the DAC A samples are read. The samples for
; the other 3 DACs are read at an offset to this rolling pointer
; DAC Function Offset from rolling pointer
; A sine 0
; B inverse sine 16
; C cosine 8
; D inverse cosine24
;
; The on-chip timer is used to generate interrupts at a fixed rate. The interrupt service
; routine first pulses LDAC low to update all DACs simultaneously with the values which
; were written to them in the previous interrupt. Then all 4 DAC values are fetched and
; written out through the synchronous serial interface. Finally, the rolling pointer is
; incremented to address the next sample, ready for the next interrupt.

TLV5614IYZ INTERFACED TO MCS®51 MICROCONTROLLER
Hardware Interfacing
Figure 18 shows an example of how to connect the TLV5614IYZ to an MCS51 Microcontroller. The serial DAC
input data and external control signals are sent via I/O Port 3 of the controller. The serial data is sent on the RxD
line, with the serial clock output on the TxD line. Port 3 bits 3, 4, and 5 are configured as outputs to provide the
DAC latch update (LDAC), chip select (CS) and frame sync (FS) signals for the TLV5614IYZ. The active low
power-down pin (PD) of the TLV5614IYZ is pulled high to ensure that the DACs are enabled.

The example is the same as for the TMS320C203 in this data sheet, but adapted for a MCS51 controller. It
generates a differential in-phase (sine) signal between the VOUTA and VOUTB pins, and its quadrature (cosine)
signal is the differential signal between VOUTC and VOUTD.
The on-chip timer is used to generate interrupts at a fixed frequency. The related interrupt service routine pulses
LDAC low to update all four DACs simultaneously, then fetches and writes the next sample to all four DACs. The

The serial port of the controller is used in Mode 0, which transmits eight bits of data on RxD, accompanied by a
synchronous clock on TxD. Two writes concatenated together are required to write a complete word to the
TLV5614IYZ. The CS and FS signals are provided in the required fashion through control of IO port 3, which has
bit-addressable outputs.

SBAS401 – DECEMBER 2006
USING THE TLV5614IYZ WAFER CHIP-SCALE PACKAGE (WCSP)
TLV5614 qualifications are done using a wire-bonded small outline (SO) package. The qualifications include:
steady state life, thermal shock, ESD, latch-up, biased HAST, autoclave, and characterization. These qualified
devices are orderable as TLV5614IDW.
NOTE: The wafer chip-scale package (WCSP) for the TLV5614IYZ uses the same die as TLV5614IDW, but is
not qualified. WCSP qualification, including board level reliability (BLR), is the responsibility of the customer.
It is recommended that underfill be used for increased reliability. BLR is application-dependent, but may include
tests such as: temperature cycling, drop test, key push, bend, vibration, and package shear.
For general guidelines on board assembly of the WCSP, the following documentation provides more details:
•
•
Application Report NanoStar™ & NanoFree™ 300µm Solder Bump WCSP Application—SBVA017
Design Summary WCSP Little Logic—SCET007B
NOTE: The use of underfill is required and greatly reduces the risk of thermal mismatch fails.
Underfill is an epoxy/adhesive that may be added during the board assembly process to improve board
level/system level reliability. The process of underfilling is to dispense the epoxy under the device after die
attach reflow. The epoxy adheres to the body of the device and to the printed circuit board (PCB). It reduces
stress placed upon the solder joints as a result of the thermal coefficient of expansion (TCE) mismatch between
the board and the component. Underfill material typically consists of silica or other fillers to increase modulus of
an epoxy, reduce creep sensitivity, and decrease the material TCE.
The recommendation for peak flow temperatures of +220°C to +230°C is based on general empirical results that
indicate that this temperature range is needed to facilitate good wetting of the solder bump to the substrate or
PCB. Lower peak temperatures may cause nonwets (cold solder joints).

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
