D/A Converter Series for Electronic Adjustments

Standard 8bit 4ch・6ch Type

D/A Converters

BH2227FV, BH2228FV

No.09052EAT04

●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-5.5V), providing

design flexibility.

●Features

1) Suitable for 2 independent power sources (3V/5V)

2) Built-in RESET function

3) High speed output response characteristics

4) 3-line serial interface

5) Broad power supply voltage range: 2.7V-5.5V

●Applications

DVCs, DSCs, DVDs, CD-Rs, CD-RWs
