PRODUCT HIGHLIGHTS

1. Two Complete ADC Functions Allow Simultaneous Sampling and Conversion of Two Channels. Each ADC has three fully/pseudo differential pairs, or six single-ended channels, as programmed. The conversion result of both channels is simultaneously available on separate data lines, or in succession on one data line if only one serial port is available.

2. High Throughput with Low Power Consumption. The AD7266 offers a 1.5 MSPS throughput rate with 11.4 mW maximum power dissipation when operating at 3 V.

3. The AD7266 offers both a standard 0 V to VREF input range and a 2 × VREF input range.

4. No Pipeline Delay. The part features two standard successive approximation ADCs with accurate control of the sampling instant via a CS input and once off conversion control. 1 Protected by U.S. Patent No. 6,681,332
