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 over-sampling-ratio reduces the external anti-alias requirements to first order in most cases. The digital filter frequency response can be programmed to be either low-pass or band-pass. * 16-Bit Sigma-Delta ADC 1.2 MSPS Output Word Rate 32x/16x Oversampling Ratio Low-Pass and Band-Pass Digital Filter Linear Phase https://elecena.pl/product/691383/16-bit-1-2-msps-cmos-sigma-delta-adc 2008-07-05 https://elecena.pl/product/691383/16-bit-1-2-msps-cmos-sigma-delta-adc 2018-03-29 https://elecena.pl/product/691383/16-bit-1-2-msps-cmos-sigma-delta-adc 2025-01-19
