ADM12914-1ARQZ

ADM12914-1ARQZ is an Analog Devices isolated signal-conditioning front end. It provides galvanic isolation between the measurement domain and the system, enabling safe sensing of high-voltage/current signals. The device typically integrates signal conditioning, an analog-to-digital converter, and a digital interface (SPI), with programmable gain, filtering, and data rates, plus built-in protection features (fault reporting, over/under-voltage, input protections). The “-1ARQZ” suffix denotes the specific variant and package type for RoHS-compliant use.
Typical applications include motor drives, power supplies, renewable energy inverters, industrial controls, and battery-management systems—anywhere isolated, accurate voltage/current measurements are required. For exact electrical specs, pinout, timing, and application guidance, refer to the official Analog Devices data sheet for ADM12914-1ARQZ.
