AD7142ACPZ-REEL

The AD7142ACPZ-REEL is a high-resolution 16-bit Capacitance-to-Digital Converter IC manufactured by Analog Devices Inc. This device is designed for precise capacitive sensing applications and supports up to 14 separate input channels, making it suitable for multi-sensor configurations.

Key electrical specifications include a fast sampling rate of 250,000 samples per second and an SPI data interface for digital communication. It operates on a single power supply voltage ranging from 2.6V to 3.6V, contributing to low power consumption. The operating temperature range is -40°C to +85°C, suitable for industrial environments.

Packaged in a 32-pin LFCSP-VQ (5x5 mm) surface mount device, the AD7142ACPZ-REEL includes an exposed thermal pad for improved heat dissipation. Its design is well-suited for applications such as capacitive touchscreens, sliders, proximity sensors, liquid level sensing, and humidity sensors.

This IC is ideal for industrial control systems and medical devices requiring accurate capacitive measurements. Its selection is recommended when high-resolution capacitance measurement, multiple input channels, and a high sample rate are critical design requirements.
