Overview
The AD7961BCPZ from Analog Devices Inc. is a 16-bit, 5 MSPS (Mega Samples Per Second) charge redistribution successive approximation (SAR) analog-to-digital converter (ADC). This component is designed to convert analog signals into digital signals with high precision and speed. The SAR architecture of the AD7961BCPZ ensures unmatched performance in terms of noise and linearity. It features a low power, high speed, 16-bit sampling ADC, an internal conversion clock, and an internal reference buffer. The ADC samples the voltage difference between the IN+ and IN− pins and provides conversion results through a single LVDS self-clocked or echoed clock serial interface.
