Analog Devices AD7864 12‑Bit ADC Datasheet
The AD7864 from Analog Devices is a high‑speed, low‑power 4‑channel simultaneous‑sampling 12‑bit analog‑to‑digital converter that operates from a single 5 V supply. It integrates a successive‑approximation ADC, four track‑and‑hold amplifiers, an on‑chip reference, and a high‑speed parallel interface.
The device offers selectable input ranges (±10 V/±5 V, 0‑2.5 V/0‑5 V, or ±2.5 V) and supports both hardware and software channel sequencing. Typical power consumption is 90 mW, with a standby mode as low as 20 µW, making it suitable for portable and power‑sensitive applications such as motor control and data acquisition.
