... 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. ● ...
