AD7190BRUZ-REEL: High Precision, Low Noise Analog-to-Digital Converter

The AD7190BRUZ-REEL from Analog Devices Inc. is a state-of-the-art 24-bit sigma-delta analog-to-digital converter (ADC) that offers industry-leading performance in noise, linearity, and resolution. This component is designed for direct interfacing to low-level sensor signals, making it an ideal choice for high-precision measurement applications in instrumentation, industrial control systems, and medical devices.

Featuring a low-noise programmable gain array (PGA) and a precision delta-sigma modulator, the AD7190BRUZ-REEL delivers a very high degree of accuracy and noise performance. The device supports data output rates from 4.7 Hz to 4.8 kHz, allowing designers to trade off between resolution and speed depending on the application requirements.

The AD7190BRUZ-REEL offers a flexible input multiplexer that can handle up to eight single-ended channels or four differential channels, providing versatility for various signal sources. The integrated PGA allows for gains from 1 to 128, which, combined with the low noise performance, enables the measurement of small amplitude signals close to the noise level.

With an on-chip low drift voltage reference, the ADC maintains a consistent performance over a wide temperature range. The device operates from a single 3 V to 5 V power supply, and its power consumption scales with throughput, making it suitable for battery-powered and portable applications where power efficiency is crucial.

The AD7190BRUZ-REEL comes in a compact TSSOP-24 package and is part of the REEL packaging format, which is designed for efficient handling and manufacturing processes, particularly for high-volume production. This ADC also includes a serial peripheral interface (SPI) compatible serial interface, which simplifies the connection to microcontrollers and digital systems.

For applications that demand the highest accuracy and lowest noise, the AD7190BRUZ-REEL from Analog Devices Inc. is an optimal solution, offering unparalleled performance in a small form factor and at a competitive price point.
