description

The

TLV5616

is

a

12-bit

voltage

output

digital-to-analog 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 TLV5616 is

programmed with a 16-bit serial string containing

4 control and 12 data bits. Developed for a wide

range of supply voltages, the TLV5616 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 TLV5616 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 TLV5616C is characterized for operation from 0

°C

to 70

°C. The TLV5616I is characterized for operation from –40°C to 85°C.
