D/A Converters

BH2227FV

BH2228FV

General Description

The BH2227FV and BH2228FV ICs are 8bit R-2R-type

D/A converters with 4 and 6 channels, respectively.

Optimized circuitry allows two output voltages to be

supplied (3V/5V). Furthermore, the built-in RESET

function ensures that the output voltage at all channels

is LOW during power up. A broad power supply voltage

range is available (2.7V to 5.5V), providing design

flexibility.

Features
