DESCRIPTION
The TLV5636 is a 12-bit voltage output DAC with a flexible 4-wire serial interface. The serial interface allows
glueless interface to TMS320 and SPI™, QSPI™, and Microwire™ serial ports. It is programmed with a 16-bit
serial string containing 4 control and 12 data bits.
The resistor string output voltage is buffered by a x2 gain rail-to-rail output buffer. The programmable settling
time of the DAC allows the designer to optimize speed vs power dissipation. With its on-chip programmable
precision voltage reference, the TLV5636 simplifies overall system design.
Because of its ability to source up to 1 mA, the reference can also be used as a system reference. Implemented
with a CMOS process, the device is designed for single supply operation from 2.7 V to 5.5 V. It is available in an
8-pin SOIC and 8-pin MSOP package to reduce board space in standard commercial and industrial temperature
ranges

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. Tested from code 10 to code 4095.
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. Tested from code 10 to code 4095.
Zero-scale error is the deviation from zero voltage output when the digital input code is zero.
Zero-scale-error temperature coefficient is given by: EZS TC = [EZS (Tmax) - EZS (Tmin)]/Vref x 106/(Tmax - Tmin).
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.
Gain error temperature coefficient is given by: EG TC = [EG(Tmax) - EG (Tmin)]/Vref x 106/(Tmax - Tmin).

APPLICATION INFORMATION
GENERAL FUNCTION
The TLV5636 is a 12-bit, single supply DAC, based on a resistor string architecture. It consists of a serial
interface, a speed and power-down control logic, a programmable internal reference, a resistor string, and a
rail-to-rail output buffer.
The output voltage (full scale determined by external reference) for each channel 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 illustrated in the data
format section. A power-on reset initially resets the internal latches to a defined state (all bits zero).
SERIAL INTERFACE
The device has to be enabled with CS set to low. A falling edge of FS starts shifting the data bit-per-bit (starting
with the MSB) to the internal register on high-low transitions of SCLK. After 16 bits have been transferred or FS
rises, the content of the shift register is moved to the DAC latch, which updates the voltage output to the new
level.
The serial interface of the TLV5636 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 (DSP or microcontroller). Figure 13 shows an example with two TLV5636s 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 14 shows an
example of how to connect the TLV5636 to TMS320, SPI™ or Microwire™ using only three pins.

Notes on SPI and Microwire: Before the controller starts the data transfer, the software has to generate a falling
edge on the I/O pin connected to FS. If the word width is 8 bits (SPI and Microwire), two write operations must be
performed to program the TLV5636. After the write operation(s), the DAC output is updated automatically on the
next positive clock edge following the sixteenth falling clock edge.
SERIAL CLOCK AND UPDATE RATE
The maximum serial clock frequency is given by:
1
f sclkmax 20 MHz
t whmin t wlmin
(1)
The maximum update rate is:
1
f updatemax 1.25 MHz
16 t whmin t wlmin
(2)
Note that the maximum update rate is just a theoretical value for the serial interface, as the settling time of the
TLV5636 has to be considered, too.
DATA FORMAT
The 16-bit data word for the TLV5636 consists of two parts:

The DAC output is updated on the rising clock edge after D0 is sampled.
To output data consecutively using the same DAC configuration, it is not necessary to program the CONTROL
register again.

LINEARITY, OFFSET, AND GAIN ERROR USING SINGLE END SUPPLIES
When an amplifier is operated from a single supply, the voltage offset can still be either positive or negative. With
a positive offset, the output voltage changes on the first code change. With a negative offset, the output voltage
may not change with the first code, depending on the magnitude of the offset voltage.
The output amplifier attempts to drive the output to a negative voltage. However, because the most negative
supply rail is ground, the output cannot drive below ground and clamps the output at 0 V.
The output voltage then remains at zero until the input code value produces a sufficient positive output voltage to
overcome the negative offset voltage, resulting in the transfer function shown in Figure 15.

Figure 15. Effect of Negative Offset (Single Supply)
This offset error, not the linearity error, produces this breakpoint. The transfer function would have followed the
dotted line if the output buffer could drive below the ground rail.
For a DAC, linearity is measured between zero-input code (all inputs 0) and full-scale code (all inputs 1) after
offset and full scale are adjusted out or accounted for in some way. However, single supply operation does not
allow for adjustment when the offset is negative due to the breakpoint in the transfer function. So the linearity is
measured between full-scale code and the lowest code that produces a positive output voltage.
POWER-SUPPLY BYPASSING AND GROUND MANAGEMENT
Printed-circuit boards that use separate analog and digital ground planes offer the best system performance.
Wire-wrap boards do not perform well and should not be used. The two ground planes should be connected
together at the low-impedance power-supply source. The best ground connection may be achieved by
connecting the DAC AGND terminal to the system analog ground plane, making sure that analog ground currents
are well managed and there are negligible voltage drops across the ground plane.
A 0.1-µF ceramic-capacitor bypass should be connected between VDD and AGND and mounted with short leads
as close as possible to the device. Use of ferrite beads may further isolate the system analog supply from the
digital power supply.
Figure 16 shows the ground plane layout and bypassing technique.

DEFINITIONS OF SPECIFICATIONS AND TERMINOLOGY
Integral Nonlinearity (INL)
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.
Differential Nonlinearity (DNL)
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.
Zero-Scale Error (EZS)
Zero-scale error is defined as the deviation of the output from 0 V at a digital input value of 0.
Gain Error (EG)
Gain error is the error in slope of the DAC transfer function.
Total Harmonic Distortion (THD)
THD is the ratio of the rms value of the first six harmonic components to the value of the fundamental signal. The
value for THD is expressed in decibels.
Signal-To-Noise Ratio + Distortion (S/N+D)
S/N+D is the ratio of the rms value of the output signal to the rms sum of all other spectral components below the
Nyquist frequency, including harmonics but excluding dc. The value for S/N+D is expressed in decibels.
Spurious Free Dynamic Range (SFDR)
Spurious free dynamic range is the difference between the rms value of the output signal and the rms value of
the largest spurious signal within a specified bandwidth. The value for SFDR is expressed in decibels.
