ADI AD7960BCPZ-RL7

The AD7960 is an 18-bit, 5 MSPS, charge redistribution successive approximation register (SAR) ADC. The SAR architecture delivers unmatched noise performance and linearity. The AD7960 integrates a low-power, high-speed 18-bit sampling ADC, an internal conversion clock, and an internal reference buffer. At the CNV± edge, the AD7960 samples the voltage difference between the IN+ and IN− pins. The voltage swing on these two pins ranges between 0 V and 4.096 V, and between 0 V and 5 V, in opposite phase. The reference voltage is applied externally to the device. All conversion results are available via an LVDS self-clocked or echo-clocked serial interface. The AD7960 is available in a 32-lead LFCSP (QFN) package and operates over a temperature range of −40°C to +85°C.
