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.
