GENERAL DESCRIPTION
The AD7960 is an 18-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 AD7960 contains a low power, high speed,
18-bit sampling ADC, an internal conversion clock, and an
internal reference buffer. On the CNV± edge, the AD7960
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 AD7960 is available in a 32-lead LFCSP (QFN) with
operation specified from −40°C to +85°C.
