CMOS, Octal, 8-Bit DAC

Maxim's MX7228 contains eight 8-bit voltage output digital-to-analog converters (DACs) with separate input latches and output buffers for simple microprocessor and TTL/CMOS interfacing. The MX7228 maintains 8-bit accuracy over the full operating temperature range without external trimming. Internally, data transfer into the data registers is via a common 8-bit TTL/CMOS compatible input bus. Logic inputs A2, A1, and A0 control which DAC is loaded after active-low WR goes low.
