AD7961BCPZ Datasheet PDF - ADI

●Product Details

●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/5 V. The reference voltage is applied to the part externally. All conversion results are available on a single LVDS self-clocked or echo-clocked serial interface.

●The AD7961 is available in a 32-lead LFCSP (QFN) with operation specified from −40°C to +85°C.
