AD872A is a monolithic 12-bit, 10 MSPS analog-to-digital converter with an on-chip, high performance track-and-hold amplifier and voltage reference.
The AD872A is a 12‑bit, 10 MSPS monolithic A/D converter from Analog Devices. It features a low‑noise 0.26 LSB rms input‑referred noise, on‑chip track‑and‑hold, and selectable single‑ended or differential inputs. The device is offered in a 28‑lead ceramic DIP (D‑28) and a 44‑terminal leadless chip carrier (E‑44A).
The datasheet provides detailed electrical specifications, absolute‑maximum ratings, pin descriptions, and dynamic performance graphs. It also includes ordering information, package dimensions, and definitions of key specifications such as INL, DNL, and aperture jitter.
