18-Bit, 2 MSPS SAR ADC

The AD7641 is a 18-bit, 2 MSPS, charge redistribution SAR, fully differential Analog-to-digital converter 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 Buffer error correction circuits, and both serial and parallel system Interface ports. It features a very high sampling rate mode (Warp) and a fast mode (Normal) for asynchronous conversion rate applications.
The AD7641 is hardware factory calibrated and comprehensively tested to ensure ac parameters such as signal-to-noise ratio (SNR) and total harmonic distortion (THD) in addition to the more traditional dc parameters of gain, offset and linearity.
Operation is specified from 40C to +85C.
