EVAL-AD7961FMCZ Datasheet PDF - Analog Devices

GENERAL DESCRIPTION
The AD7961 is a 16-bit, 5 MSPS, charge redistribution successive approximation (SAR), analog-to-digital converter (ADC). The SAR architecture allows unmatched performance both in noise and in linearity. The AD7961 contains a low power, high speed, 16-bit sampling ADC, an internal conversion clock, and an internal reference buffer. On the CNV± edge, the AD7961 samples the voltage difference between the IN+ and IN− pins.
