AD7943BNZ

AD7943BNZ is a fast 12bit multiplying DAC that operates from a single +5V supply (normal mode) and a single +3.3V to +5V supply (biased mode). The AD7943 has a serial interface. It will replace the industry-standard AD7543, in many applications, and it offers superior speed and power consumption performance. It is used in applications such as battery-powered instrumentation, and laptop computers.
