Overview
The AD4134BCPZ, produced by Analog Devices Inc., is a 24-bit, 4-channel, simultaneous sampling analog-to-digital converter (ADC) that utilizes a continuous time sigma-delta (CTSD) modulation scheme. This architecture eliminates the need for traditional switched capacitor circuitry, simplifying the analog front-end and reducing noise, error, mismatch, and distortion. The device is designed for high-density multichannel data acquisition and supports a wide range of sensor types, including temperature, pressure, vibration, and shock sensors.
