GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

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.

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.

The AD977/AD977A is comprehensively tested for ac param-

eters such as SNR and THD, as well as the more traditional dc

parameters of offset, gain and linearity.
