AD7864 is a high-speed, high-precision, 4-channel, simultaneous sampling, 12-bit ADC
The AD7864 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 features four track‑hold amplifiers, a 1.65 µs conversion time per channel, and a high‑speed parallel data bus.
Designed for applications such as AC motor control, UPS, data acquisition and communications, the device offers selectable input ranges, low power modes (20 pW standby), and extensive timing and protection features.
