Description

The MB40D001 is an 8-bit D/A converter with 12 built-in channels. The 12 sets of analog outputs have built-in OP amps to enable use with large current drive applications.

CS (chip select) data input/output format is used to enable connection to a serial bus. A built-in 12-bit I/O expander provides serial <=> parallel conversion (MB40D001: 8 of the 12 bits are also used with analog output).

The MB40D001 can be adapted for microcontroller port expansion, or replacement of electronic volume control or semi-fixed calibration resistance.

Also, the MB40D001 is function- and pin-compatible with the MB88146A, for easy replacement when reducing sysytem operating voltage.
