The AD7863 is a high speed, low power, dual 14-bit analog-to-digital converter that operates from a single 5 V supply. It has two independent 14-bit ADCs, each with two channels, for simultaneous sampling and conversion of four signals. The AD7863 also features overvoltage protection, a high speed parallel interface, and a low power mode.
The AD7863 is a high‑speed, low‑power dual 14‑bit analog‑to‑digital converter that operates from a single 5 V supply. It provides simultaneous sampling of two channels, preserving relative phase information, and offers three selectable input voltage ranges (+10 V, +2.5 V, 0‑2.5 V).
Key features include a 5.2 µs conversion time, 70 mW typical power consumption in normal mode, a high‑speed parallel interface, and over‑voltage protection on the analog inputs. The device is offered in SOIC and SSOP packages and is suitable for battery‑powered or portable applications.
