高共模电压,可编程增益差动放大器 High Common-Mode Voltage, Programmable Gain Difference Amplifier
GENERAL DESCRIPTION
The AD628 is a precision difference amplifier that combines excellent dc performance with high common-mode rejection over a wide range of frequencies. When used to scale high voltages, it allows simple conversion of standard control voltages or currents for use with single-supply ADCs. A wideband feedback loop minimizes distortion effects due to capacitor charging of Σ-Δ ADCs.
