Wed, 03/10/2010 - 2:32pm
20 bit DAC for MRIAnalog Device’s AD5791 high-accuracy 20-bit digital-to-analog converter (DAC) is said to be the industry’s first to feature true 1-ppm (parts per million) resolution and accuracy, provides four times greater accuracy and four times more resolution than competing converters. The AD5791 features 1-ppm resolution and accuracy, low noise (sub 1 ppm), fast refresh rates (1 us), and low output drift (sub 1 ppm), a relative accuracy specification of ±1 LSB max, and operation is guaranteed monotonic with a ±1 LSB DNL max specification. The output can be configured for standard unipolar (+5 V, +10 V) or bipolar (±5 V, ±10 V) output ranges. The AD5791 uses a three-wire serial interface that operates at clock rates up to 50 MHz.
