NRND6,953 in stock

Overview

The AD7124-8BCPZ is a low power, low noise, completely integrated analog front end for high precision measurement applications. This 24-bit sigma-delta ADC includes an integrated PGA, a precision reference, and flexible multiplexing for up to 15 pseudo-differential or 8 fully differential channels.

Why Choose This Part

This device offers three integrated power modes (Low, Mid, and Full Power) to optimize the noise performance versus current consumption for battery-operated designs. It simplifies system design by integrating essential components like a temperature sensor, cross-point multiplexer, and burnout currents for sensor diagnostics.

Applications

Temperature Controllers
Precise measurement of RTDs, thermocouples, and thermistors using the integrated excitation currents and PGA.
Pressure Measurement
High-resolution bridge sensor interfacing for industrial weighing scales and strain gauges.
Process Control
Multichannel monitoring of 4-20mA loops and voltage outputs in PLC and distributed control systems.
Instrumentation
Portable or battery-powered measurement devices requiring high dynamic range and low power consumption.
