- Fast Settling: 600 ns to 0.01% with AD843
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.

Tools & Simulations
Precision DAC Error Budget Tool
The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
