GENERAL DESCRIPTION
The AD976/AD976A is a high speed, low power 16-bit A/D
converter that operates from a single 5 V supply. The part con-
tains 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 param-
eters 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’ propri-
etary 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.
PRODUCT HIGHLIGHTS
1. Fast Throughput.
The AD976/AD976A is a high speed (100 kSPS/200 kSPS
throughput rates respectively), 16-bit ADC based on a
switched capacitor architecture.
2. Single-Supply Operation.
The AD976/AD976A operates from a single 5 V supply and
dissipates only 100 mW max.
3. Comprehensive DC and AC Specifications.
The AD976/AD976A is factory calibrated and fully tested for
SNR and THD as well as the traditional specifications of
offset, gain and linearity.
4. Complete A/D Solution.
The AD976/AD976A offers a highly integrated solution
containing an accurate ADC, reference and on-chip clock.
