AD7782BRUZ - Precision Low Power 20-bit Sigma-Delta ADC from Analog Devices Inc.

The AD7782BRUZ is a high precision, low power, 20-bit analog-to-digital converter (ADC) from Analog Devices Inc., designed to provide exceptional performance in a wide range of applications that require accurate data acquisition. This sigma-delta ADC is particularly well-suited for applications such as portable instrumentation, medical devices, industrial process control, and smart sensor systems where power efficiency and precision are paramount.

Featuring a 20-bit charge-balanced sigma-delta modulator, this ADC delivers a high degree of resolution with a total unadjusted error (TUE) of less than 0.0015% and a noise-free resolution of up to 17 bits at a 10 Hz update rate. The AD7782BRUZ operates from a single 2.7 V to 5.25 V power supply, making it versatile for both battery-powered and line-powered systems.

One of the key advantages of the AD7782BRUZ is its ease of use. The device includes an on-chip oscillator, eliminating the need for external clock sources. It also features a simple 3-wire serial interface that is SPI and microcontroller compatible, allowing for straightforward integration into digital systems.

The AD7782BRUZ incorporates a power-saving feature that reduces the power consumption to just 1 mW at a 10 Hz update rate, and the power scales linearly with the throughput. This low power consumption, combined with its small TSSOP-16 package, makes the ADC an excellent choice for portable and space-constrained applications.

Additional features of the AD7782BRUZ include a differential analog input that is capable of handling ±VREF input ranges, an internal buffer for the analog input, and an internal reference that simplifies the design process. The device also includes a filter synchronization feature that allows multiple devices to be synchronized in a system, reducing noise and improving overall system performance.

With its combination of high precision, low power consumption, and compact form factor, the AD7782BRUZ from Analog Devices Inc. is an ideal solution for designers looking to enhance the accuracy and efficiency of their data acquisition systems.
