Product Details

The AD7543 is a precision 12-bit monolithic CMOS multiplying DAC designed for serial interface applications.

The DAC's logic circuitry consists of a 12-bit serial-in parallelout shift register (Register A) and a 12-bit DAC input register (Register B). Serial data at the AD7543 SRI pin is clocked into Register A on the leading or trailing edge (user selected) of the strobe input. Once Register A is full its contents are loaded into Register B under control of the LOAD inputs.

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.
