D/A Converter Series for Electronic Adjustments
Standard 8bit 10ch/12ch
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
●Lineup
