AD7961BCPZ-RL7

AD7961BCPZ-RL7 is a 16bit, 5MSPS, charge redistribution successive approximation (SAR), analogue-to-digital converter (ADC). The SAR architecture allows unmatched performance both in noise and linearity. It contains a low power, high speed, 16bit sampling ADC, an internal conversion clock, and an internal reference buffer. On the CNV±edge, this device samples the voltage difference between the IN+ and IN- pins. The voltages on these pins swing in opposite phases between 0V and 4.096V and between 0V and 5V. The reference voltage is applied to the part externally. It is used in applications such as digital imaging systems, digital X-rays, computed tomography, IR cameras, MRI gradient control, high-speed data acquisition, spectroscopy, and test equipment.
