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
