GENERAL DESCRIPTION

AD7945

OUT1

The AD7943, AD7945 and AD7948 are fast 12-bit multiplying

DACs that operate from a single +5 V supply (Normal Mode)

and a single +3.3 V to +5 V supply (Biased Mode). The

AD7943 has a serial interface, the AD7945 has a 12-bit parallel

interface, and the AD7948 has an 8-bit byte interface. They will

replace the industry-standard AD7543, AD7545 and AD7548

in many applications, and they offer superior speed and power

consumption performance.
