The AD5791 high-accuracy 20-bit D/A converter is offered as the first to feature true 1-ppm resolution and accuracy — which according to the company is four times greater accuracy and four times more resolution than competing converters. The part features a low noise of less than 1 ppm, refresh rates of 1 µs, and a low output drift of less than 1 ppm.

The DAC offers a relative accuracy specification of ±1 LSB max, and operation is guaranteed monotonic with a ±1-LSB DNL max specification. The product delivers 0.025-ppm low-frequency noise and features 0.05-ppm/°C output drift.

The output can be configured for standard unipolar (+5-V, +10-V) or bipolar (±5-V, ±10-V) output ranges. Housed in a 20-lead TSSOP, the AD5791 uses a versatile three-wire serial interface that operates at clock rates up to 50 MHz.
