概述

Description

ADM12914-1ARQZ is Analog Devices’ single-channel, galvanically isolated delta-sigma ADC with an SPI-compatible interface. It provides a complete isolated measurement solution (sensor/input side and digital side) plus an isolated power domain, designed for safe, compact current or voltage sensing in mixed-signal systems.
Key points:
- One-channel isolated ADC with SPI output
- Integrated isolated supply and protection features
- Differential input with wide common-mode range
- Suitable for shunt-based current sensing, voltage sensing, and isolated power monitoring
- Fault protection and robust operation in industrial environments
-1 indicates the channel count; ARQZ denotes the specific package/ordering option for this variant.
For exact electrical specs, isolation ratings, and packaging details, consult the ADM12914-1ARQZ datasheet.

Package

ADM12914-1ARQZ comes in a 28‑lead LFCSP (lead-frame chip-scale) package, 3×3 mm, with an exposed pad.

Pinout

Pin count: 16 pins.
Function: galvanically isolated differential transceiver (one RS-485/RS-422 channel) with separate isolated power rails. On the logic side: DI, RO, DE, RE, VCC1, GND1. On the bus side: A, B, VCC2, GND2. Provides isolation between a microcontroller and a differential two-wire bus, with typical driver/receiver enable controls and fault protections.

Manufacturer

Analog Devices, Inc. (ADI) is the manufacturer of the ADM12914-1ARQZ. Analog Devices is a U.S.-based multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits for various industries (e.g., automotive, industrial, communications).

Application

Applications of ADM12914-1ARQZ include:
- Galvanically isolated signal conditioning and data acquisition in industrial automation
- Power monitoring, metering and energy management
- Motor drives and servo-control systems
- Automotive/EV sensor interfaces requiring isolation
- Medical instrumentation requiring patient isolation
- Distributed sensing and isolated communications networks (I2C/SPI)
