The BH2227FV and BH2228FV are 8-bit 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.
The BH2227FV (4‑channel) and BH2228FV (6‑channel) are 8‑bit R‑2R type D/A converters with dual supply options (3 V/5 V) and a built‑in reset function. They operate over a wide supply range of 2.7 V to 5.5 V and are suited for audio‑visual, office‑automation, communication and consumer electronic devices.
