AD7724 Dual CMOS Modulators

STBY RESET This device consists of two seventh order sigma-delta modulators. Each modulator converts its analog input signal into a high speed 1-bit data stream. The part operates from a 5 V power supply and accepts a differential input range of 0 V to +2.5 V or ± 1.25 V centered about a common-mo.
