BH2227FV_09 Datasheet, PDF (1/9 Pages) Rohm – Standard 8bit 4ch-E6ch Type D/A Converters

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
