AD7948:  +3.3 V/+5 V Multiplying 12-Bit DAC With an 8-Bit Byte Interface

Product Details


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.

The AD7943 is available in 16-pin DIP, 16-pin SOP (Small Outline Package) and 20-pin SSOP (Shrink Small Outline Package).

The AD7945 is available in 20-pin DIP, 20-pin SOP and 20-pin SSOP.

The AD7948 is available in 20-pin DIP, 20-pin SOP and 20-pin SSOP.
