Product Summary

The AD977A is a high speed, low power 16-bit A/D converter that operates from a single 5 V supply. The AD977A has a throughput rate of 200 kSPS whereas the AD977A has a throughput rate of 100 kSPS. Each part contains a successive approximation, switched capacitor ADC, an internal 2.5 V reference, and a high speed serial interface. The ADC is factory calibrated to minimize all linearity errors. The AD977A is specified for full scale bipolar input ranges of ±10V, ±5V and±3.3V, and unipolar ranges of 0V to 10V, 0V to 5V and 0V to 4V.
