description
The TL V5626 is a dual 8-bit voltage output DAC with a flexible 3-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 2 control and 8 data bits.
The resistor string output voltage is buffered by a x2 gain rail-to-rail output buffer . The buffer features a Class AB
output stage to improve stability and reduce settling time. The programmable settling time of the DAC allows
the designer to optimize speed versus power dissipation. With its on-chip programmable precision voltage
reference, the TLV5626 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 package to reduce board space in standard commercial and industrial temperature ranges.

TLV5626
2.7-V TO 5.5-V LOW-POWER DUAL 8-BIT DIGITAL-TO-ANALOG
The TLV5626 is a dual 8-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 reference) is given by:
2REF
CODE
0x1000
[V]
Where REF is the reference voltage and CODE is the digital input value in the range 0x000 to 0xFF0.Bits 3 to
0 must be set to zero. A power-on reset initially puts the internal latches to a defined state (all bits zero).
serial interface
A falling edge of CS 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 CS rises, the content of the shift register is moved to the
target latches (DAC A, DAC B, BUFFER, CONTROL), depending on the control bits within the data word.
Figure 13 shows examples of how to connect the TLV5626 to TMS320, SPI, and Microwire.

APPLICATION INFORMATION
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 CS. If the word width is 8 bits (SPI and Microwire), two write
operations must be performed to program the TL V5626. After the write operation(s), the holding registers or the
control register are updated automatically on the 16

linearity, offset, and gain error using single ended 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 14.

SLAS236A –JUNE 1999 – REVISED JUNE 2000
APPLICATION INFORMATION
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.
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 (E
Gain error is the error in slope of the DAC transfer function.
signal-to-noise ratio + distortion (S/N+D)
S/N+D is the ratio of the rms value of the measured input 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 spurious signal within a specified bandwidth. The value for SFDR is expressed in decibels.
