AD977CRZ Datasheet PDF - ADI

●GENERAL DESCRIPTION

●The AD977/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 AD977 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 AD977/AD977A is specified for full scale bipolar input ranges of ±10 V, ±5 V and ±3.3 V, and unipolar ranges of 0 V to 10 V, 0 V to 5 V and 0 V to 4 V.

●The AD977/AD977A is comprehensively tested for ac parameters such as SNR and THD, as well as the more traditional dc parameters of offset, gain and linearity.

●PRODUCT HIGHLIGHTS

●1\. Fast Throughput

●   The AD977/AD977A is a high speed, 16-bit ADC based on

●a factory calibrated switched capacitor architecture.

●2\. Single-Supply Operation

●   The AD977/AD977A operates from a single 5 V supply and dissipates only 100 mW max.

●3\. Comprehensive DC and AC Specifications

●   In addition to the traditional specifications of offset, gain and linearity, the AD977/AD977A is fully tested for SNR and THD.
