AD7641BCPZRL概述

18位六百七十○分之二百五十○ kSPS时的PulSAR双极性可编程输入ADC 18-Bit 250/670 kSPS PulSAR Bipolar Programmable Inputs ADC

GENERAL DESCRIPTION

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 −40°C to +85°C.
