D/A Converter Series for Electronic Adjustments
Standard 8bit 4ch・6ch Type D/A Converters
No.11052EBT04
BH2227FV, BH2228FV
●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
