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.
The BH2223FV and BH2221FV are high‑performance 8‑bit R‑2R type D/A converters offering 10 and 12 output channels respectively. They include a built‑in RESET function that forces all outputs low on power‑up and support a wide 2.7 V‑5.5 V supply range for flexible design.
