The part contains a successive approximation, switched capacitor ADC, an internal 2.5 V reference and a high speed parallel interface. The ADC is factory calibrated to minimize all linearity errors. The analog full-scale input is the standard industrial range of ± 10 V. The AD976/AD976A is prehensively tested for ac parameters such as SNR and THD, as well as the more traditional parameters of offset, gain and linearity. The AD976/AD976A is fabricated on Analog Devices’ proprietary Bi CMOS process, which has high performance bipolar devices along with CMOS transistors. The AD976/AD976A is available in skinny 28-lead DIP, SSOP and SOIC packages. 1. Fast Throughput. The AD976/AD976A is a high speed (100 k SPS/200 k SPS throughput rates respectively), 16-bit ADC based on a switched capacitor architecture. 2. Single-Supply Operation. The AD976/AD976A operates from a single 5 V supply and dissipates only 100 m W max. 3. prehensive DC and AC Specifications. The AD976/AD976A is factory calibrated and fully tested for SNR and THD as well as the traditional specifications of offset, gain and linearity. 4. plete A/D Solution. The AD976/AD976A offers a highly integrated solution containing an accurate ADC, reference and on-chip clock. REV....
