ATE GENERAL DESCRIPTION
The AD7641 is an 18-bit, 2 MSPS, charge redistribution SAR,
fully differential, analog-to-digital converter (ADC) that
operates from a single 2.5 V power supply. The part contains a
high speed, 18-bit sampling ADC, an internal conversion clock,
an internal reference (and buffer), error correction circuits, and
both serial and parallel system interface ports. It features two
very high sampling rate modes (wideband warp and warp) and
a fast mode (normal) for asynchronous rate applications. The
AD7641 is hardware factory calibrated and tested to ensure ac
parameters, such as signal-to-noise ratio (SNR), in addition to
the more traditional dc parameters of gain, offset, and linearity.
The AD7641 is available in Pb-free only packages with
operation specified from −40°C to +85°C. FUNCTIONAL BLOCK DIAGRAM …
