D/A Converter Series for Electronic Adjustments
Standard 8bit
8ch Type D/A Converters
BH2226FV,BH2226F
●Description
The BH2226FV,BH2226F is an 8bit R-2R-type D/A converter with 8 channels. The D/A converter output and
serial / parallel conversion function can be switched with one command, and a built-in RESET function
ensures that the output voltage at all channels is Low during power up. A broad power supply voltage
range (2.7V-5.5V) is available, providing design flexibility.
●Features
1) Integrated expansion port function
2) Built-in RESET function
3) High speed output response characteristics
4) 3-line-type serial interface
5) Broad power supply voltage range: 2.7V-5.5V
●Applications
DVCs, DSCs, DVDs, CD-Rs, CD-RWs
