GENERAL DESCRIPTION

64.5 mW at 5 MSPS with internal reference buffer

(echoed clock mode)

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.

39 mW at 5 MSPS with external reference buffer

(self clocked mode, CNV in CMOS mode)

SAR architecture

No latency/pipeline delay

External reference options: 2.048 V buffered to 4.096 V (internal

reference buffer), 4.096 V, and 5 V

Serial LVDS interface

Self clocked mode

Echoed clock mode

LVDS or CMOS option for conversion control (CNV signal)

Operating temperature range of −40°C to +85°C

32-lead, 5mm × 5mm LFCSP (QFN)

The AD7960 is available in a 32-lead LFCSP (QFN) with

operation specified from −40°C to +85°C.
