The AD976/AD976A is a high-speed, low-power 16-bit ADC that operates from a single 5 V supply. It contains 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 Vin=5V. The AD976/AD976A has a conversion time tCONV≈20μs, which corresponds to a sample rate of 100 kSPS. The AD976A has a conversion time tCONV≈10μs, which corresponds to a sample rate of 200 kSPS.
The AD976/AD976A family are high‑speed, low‑power 16‑bit analog‑to‑digital converters that operate from a single 5 V supply. They feature a parallel data interface, internal 2.5 V reference, and on‑chip clock, and are available in 28‑lead DIP, SSOP, and SOIC packages.
The document provides detailed electrical specifications, pin descriptions, timing diagrams, and ordering information for the various AD976/AD976A variants, including throughput rates of 100 kSPS (AD976) and 200 kSPS (AD976A).
