Overview
The AD4111BCPZ-RL7 is a precision analog-to-digital converter (ADC) manufactured by Analog Devices Inc. This device is a low-power, 24-bit, sigma-delta (Σ-Δ) ADC designed for high-precision data conversion in various applications. It integrates an analog front end (AFE) for fully differential or single-ended, high impedance voltage inputs, and current inputs. The AD4111BCPZ-RL7 operates with a single power supply, making it suitable for galvanically isolated applications, and features an embedded 2.5 V internal reference and open wire detection for system-level diagnostics.
