General Description
BH2223FV and BH2221FV are high performance 8bit
R-2R-type D/A converters with 10 and 12 channel
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.

Remark
(Note 1) Derated at 6.5mW/°C at Ta>25°C
(Note 2) Derated at 4.5mW/°C at Ta>25°C
Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over
the absolute maximum ratings.
