The AD976/AD976A is a high-speed, low-power 16-bit A/D converter that operates from a single 5V supply. The part contains a successive approximation, switched capacitor ADC, an internal 2.5V reference, and a high-speed parallel interface. The ADC is factory calibrated to minimize all linearity errors. The analog full-scale input is ±10V.
The AD976/AD976A family are high‑speed, low‑power 16‑bit analog‑to‑digital converters that operate from a single +5 V supply. They use a switched‑capacitor architecture with an on‑chip 2.5 V reference and provide a parallel data interface for direct connection to DSPs or microcontrollers.
Key features include 100 kSPS (AD976) or 200 kSPS (AD976A) throughput, 16‑bit resolution, ±10 V input range, 100 mW maximum power dissipation, and factory‑calibrated linearity specifications. The devices are offered in 28‑lead DIP, SSOP, and SOIC packages.
