Présentation

Description

The AD4111BCPZ is a low-power, 24-bit sigma-delta (Σ-Δ) ADC from Analog Devices, designed for precision measurement in industrial applications. It features 16 single-ended or 8 differential inputs, a flexible input mux, and supports ±10V, ±5V, and 0–5V ranges via integrated PGA and reference.
Key specs:
- 24-bit resolution with up to 31.25 kSPS output rate.
- Ultra-low power (1.1 mW at 31.25 kSPS).
- Integrated 2.5V reference and diagnostics.
- SPI-compatible interface.
Ideal for process control, PLCs, and sensor interfaces, it combines high accuracy with robust performance in harsh environments. The LFCSP package (32-lead) ensures compact design integration.
For details, refer to the [AD4111 datasheet](https://www.analog.com/media/en/technical-documentation/data-sheets/AD4111.pdf).
