General Description

The TC1320 is a serially accessible 8-bit voltage output

digital-to-analog converter (DAC). The DAC produces

an output voltage that ranges from ground to an exter-

nally supplied reference voltage. It operates from a sin-

gle power supply that can range from 2.7V to 5.5V,

making it ideal for a wide range of applications. Built

into the part is a Power-on Reset function that ensures

that the device starts at a known condition.

Communication with the TC1320 is accomplished via a

the TC1320 acting as a slave only device. The host can

enable the SHDN bit in the CONFIG register to activate

the Low Power Standby mode.
