概要

Description

The AD7124-4BRUZ is a low-power, 24-bit Σ-Δ ADC from Analog Devices, designed for precision measurement applications. It features 4 differential/7 pseudo-differential input channels, an integrated PGA (gain: 1–128), and low noise (22 nV/√Hz at 1x gain).
Key highlights:
- Resolution: 24-bit, with INL ±2 ppm for high accuracy.
- Flexible power modes: 30 µA (low power) to 900 µA (full power).
- On-chip features: Reference buffer, temperature sensor, and diagnostic functions.
- Interface: SPI-compatible for easy microcontroller communication.
- Applications: Industrial sensors, RTDs, thermocouples, and medical devices.
The AD7124-4BRUZ operates from 2.7V–5.25V and comes in a TSSOP-24 package. Its low noise and integrated features simplify signal-chain design for high-precision systems.

Equivalent

The AD7124-4BRUZ is a low-power, 24-bit Σ-Δ ADC. Equivalent alternatives include:
- ADS124S08 (TI) – 24-bit, low-noise, 8-channel ADC.
- LTC2498 (Analog Devices) – 24-bit, 16-channel ΔΣ ADC.
