description

The TLV5623 is a 8-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 TLV5623 is programmed

with a 16-bit serial string containing 4

control and 8 data bits. Developed for a wide

range of supply voltages, the TLV5623 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 TLV5623 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 TLV5623C is characterized for operation from 0°C

to 70°C. The TLV5623I is characterized for operation from ?40°C to 85°C.
