AD7402-8BRIZ

模数转换器 - ADC Isolated 16Bit SigmaDelta ADC Int Clock

16-Bit, Isolated Sigma-Delta Modulator

GENERAL DESCRIPTION AD7402-8BRIZ

The AD74021 is a high performance, second-order, Σ-Δ modulator

that converts an analog input signal into a high speed, single-bit

data stream, with on-chip digital isolation based on Analog

Devices, Inc., iCoupler® technology. The AD7402 operates from

a 4.5 V to 5.5 V (VDD1) power supply and accepts a differential

input signal of ±250 mV (±320 mV full scale). The differential

input is ideally suited to shunt voltage monitoring in high

voltage applications where galvanic isolation is required.
