The AD5346 / AD5347 / AD5348 are octal 8-, 10-, and 12- bit DACs, operating from a 2.5 V to 5.5 V supply. These devices incorporate an on-chip output buffer that can drive the output to both supply rails, and also allows a choice of buffered or unbuffered reference input.
The AD5346 / AD5347 / AD5348 have a parallel interface. CS selects the device and data is loaded into the input registers on the rising edge of WR. A readback feature allows the internal DAC registers to be read back through the digital port.
The GAIN pin on these devices allows the output range to be set at 0 V to VREF or 0 V to 2 x VREF.
Input data to the DACs is double-buffered, allowing simultaneous update of multiple DACs in a system using the LDAC pin.
An asynchronous CLR input is also provided, which resets the contents of the Input Register and the DAC Register to all zeros. These devices also incorporate a power-on-reset circuit that ensures that the DAC output powers on to 0 V and remains there until valid data is written to the device. All three parts are pin-compatible, which allows the user to select the amount of resolution appropriate for their application without redesigning their circuit board.

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.
