Analog Devices Inc. AD7766BRUZ-1-RL7

Description
The AD7766-2-KGD is a high-performance, 24-bit, oversampled successive approximation register (SAR) analog-to-digital converter (ADC). It combines a large dynamic range and input bandwidth while consuming only 8.5 mW of power. The AD7766-2-KGD is ideal for ultra-low power data acquisition systems, such as PCI-based and USB-based systems, and provides 24-bit resolution.
