Overview

Description

The AD7191BRUZ is a high-resolution, low-noise, 24-bit sigma-delta analog-to-digital converter (ADC) designed by Analog Devices. It is part of the AD719x series and is intended for precision measurement applications where high accuracy and stability are critical, such as weigh scales and temperature monitoring systems.
Key features of the AD7191BRUZ include:
- A programmable gain amplifier (PGA) that allows for input ranges from ±40 mV to ±2.56 V, optimizing it for both low-level and wide-range signals.
- A single differential input channel with a low drift and low noise performance.
- An on-chip clock, with optional external clock input, providing design flexibility.
- A built-in digital filter that provides a selectable data rate of up to 4.8 kHz.
- SPI-compatible serial interface for easy integration with microcontrollers or DSPs.
- Low power consumption, making it suitable for battery-operated devices.
The AD7191BRUZ operates over a wide temperature range and is available in a TSSOP package, making it ideal for compact and robust designs in industrial and instrumentation applications.
