AD7961BCPZ

AD7961 is a 16bit, 5MSPS, charge redistribution successive approximation (SAR), analogue-to-digital converter (ADC). The SAR architecture allows unmatched performance both in noise and in linearity. The AD7961 contains a low power, high speed, 16bit 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. The voltages on these pins swing in opposite phase between 0V and 4.096V and between 0V and 5V. The reference voltage is applied to the part externally. All conversion results are available on a single LVDS self clocked or echoed clock serial interface. Typical application includes digital imaging systems (digital X -rays, computed tomography, IR cameras, MRI gradient control), high speed data acquisition, spectroscopy and test equipment.
