Analog Devices AD7863 Dual 14‑Bit ADC Data Sheet
The AD7863 is a high‑speed, low‑power dual 14‑bit analog‑to‑digital converter that operates from a single 5 V supply. It contains two successive‑approximation ADCs, two track‑and‑hold amplifiers, an internal 2.5 V reference and a high‑speed parallel interface. Four analog inputs are grouped into two channels (A and B) that can be sampled and converted simultaneously, preserving phase information.
Key features include selectable input ranges (±10 V, ±2.5 V, 0‑2.5 V), a typical power consumption of 70 mW, 5.2 µs conversion time in high‑sampling mode, and over‑voltage protection up to ±17 V. The part is offered in SOIC‑28 and SSOP packages and is suited for battery‑powered, portable, and high‑throughput data‑acquisition applications.
