D/A Converter Series for Electronic Adjustments

Standard 8bit 10ch・

12ch Type

D/A Converters

BH2223FV, BH2221FV

●

Description

BH2223FV and BH2221FV are high performance 8bit R-2R-type D/A converters with 10 and 12 channels outputs, respectively.

A built-in RESET function ensures that the output voltage at all channels is Low during power up. And a broad power supply

voltage range (2.7V - 5.5V) provides design flexibility.

●

Features

1) Built-in RESET function

2) High speed output response characteristics

3) 3-line serial interface

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

●

Applications

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