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 comprehensively 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 BiCMOS 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 kSPS/200 kSPS throughput rates r...
