ADI AD7722ASZ

16195k1差分5V5V-40°C ~ 85°C

Overview

The analog input is continuously sampled by an analog modulator eliminating the need for external sample-and-hold circuitry. The modulator output is processed by two Finite Impulse Response (FIR) digital filters in series. The on-chip filtering reduces the external antialias requirements to first order, in most cases. The group delay for the filter is 215.5 µs, while the settling time for a step input is 431 µs. The sample rate, filter corner frequency, and output word rate are set by an external clock that is nominally 12.5 MHz.

The AD7722ASZ is available in a 44-pin PQFP package and is specified over the industrial temperature range from –40°C to +85°C.
