Single 5 V supply GENERAL DESCRIPTION
The AD7723 is a complete 16-bit, sigma-delta ADC. The part
operates from a 5 V supply. The analog input is continuously
sampled, eliminating the need for an external sample-and-hold.
The modulator output is processed by a finite impulse response
(FIR) digital filter. The on-chip filtering combined with a high
oversampling ratio reduces the external antialias requirements
to first order in most cases. The digital filter frequency response
can be programmed to be either low-pass or band-pass.
The AD7723 provides 16-bit performance for input bandwidths
up to 460 kHz at an output word rate up to 1.2 MHz. The …
