The TL V5606 is a 10-bit voltage output digital-toanalog converter (DAC) with a flexible 4-wire
serial interface. The 4-wire serial interface allows
glueless interface to TMS320, SPI, QSPI, and
Microwire serial ports. The TLV5606 is programmed with a 16-bit serial string containing 4
control and 10 data bits. Developed for a wide
range of supply voltages, the TLV5606 can
operate from 2.7 V to 5.5 V.

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 settling time of the DAC is programmable to allow
the designer to optimize speed versus power dissipation. The settling time is chosen by the control bits within
the 16-bit serial input string. A high-impedance buffer is integrated on the REFIN terminal to reduce the need
for a low source impedance drive to the terminal.
Implemented with a CMOS process, the TL V5606 is designed for single supply operation from 2.7 V to 5.5 V.
The device is available in an 8-terminal SOIC package. The TL V5606C is characterized for operation from 0°C
to 70°C. The TLV5606I is characterized for operation from –40°C to 85°C.

NOTES: 4. 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.
5. 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.
6. Zero-scale error is the deviation from zero voltage output when the digital input code is zero.
7. Zero-scale-error temperature coefficient is given by: EZSTC = [EZS(T
8. Gain error is the deviation from the ideal output (2V
9. Gain temperature coefficient is given by: EGTC = [EG(T
