CMOS 16-Bit, 468.75 kHz, Sigma-Delta ADC

GENERAL DESCRIPTION The AD7721 is a complete low power, 12-/16-bit, sigma-delta ADC. The part operates from a +5 V supply and accepts a differential input of 0 V to 2.5 V or ±1.25 V. The analog input is continuously sampled by an analog modulator at twice the clock frequency eliminating the need
