GENERAL DESCRIPTION

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.
