18- and 16-bit analog-to-digital converters from Analog Devices
The AD7960 and AD7961 from Analog Devices are 18- and 16-bit, 5 MSPS charge redistribution successive approximation (SAR), analog-to-digital converters (ADCs). The SAR architecture allows unmatched performance both in noise and linearity. The AD7960/61 contains a low-power, high-speed, 18- and 16-bit sampling ADC, an internal conversion clock, and an internal reference buffer. On the CNV± edge, the AD7960/61 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- or echo-clocked serial interface.
The AD7960/61 is available in a 32-lead LFCSP (QFN) with operation specified from −40°C to +85°C.
