The AD7294 is a 12-bit monitor and control system with multichannel ADC, DACs, temperature sensor, and current sense function.
The AD7294 combines a 12‑bit SAR analog‑to‑digital converter, four 12‑bit DACs, high‑side current‑sense inputs and temperature‑sensor inputs in a single‑chip solution. It is designed for high‑voltage monitoring in base‑station power amplifiers, automotive and industrial control systems.
The device operates over a wide temperature range (‑40 °C to +105 °C) and supports supply voltages from 5 V up to 59.4 V on the current‑sense inputs. Detailed specifications, functional block diagrams, and register maps are provided for hardware designers and firmware developers.
