BH2222FV is an 8bit D/A converter for electronic adjustment. The 20-channel output voltage can be independently controlled by three-wire serial interface from micro-controller. The built-in power on reset circuit keeps the output state Low after the power is on. 4-channel have data register function. Two kinds of set voltage can be retained, and output voltage can be switched by SEL pin.

Features

1) 8bit 20-channel D/A converters adopting R-2R system.

2) 3-wire + 1-wire 16-bit serial interface.

3) POWER ON RESET circuit.

4) The full scale output voltage range : 2.7 ~ 5.5V.

5) It is possible to set the two output full scale level independently.

6) 4-channel date Register extension function.

7) SSOP-B28 package.

Applications

The voltage adjustment for DVC, DSC etc.
