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.
The voltages on these pins swing in opposite phase between 0 V
and 4.096 V and between 0 V and 5 V. 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.
The AD7961 is available in a 32-lead LFCSP (QFN) with …
