Overview
The AD4115BCPZ-RL7, produced by Analog Devices Inc., is a low power, low noise, 24-bit sigma-delta (Σ-Δ) analog-to-digital converter (ADC). This component integrates an analog front end (AFE) for either eight fully differential or 16 single-ended, high impedance (≥1 MΩ), bipolar, ±10 V voltage inputs. The AD4115 is designed to provide high precision and flexibility, making it suitable for a variety of applications requiring accurate analog-to-digital conversion.
