General Description
AD628 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 - ADCs.)
A reference pin (VREF bipolar to single-sided signals. The AD628 converts +5 V, +10 V +5 V, +10 V, and 4 to 20 mA input signals to a single-ende output within the input range of single-supply ADCs.
The AD628 has an input common-mode and differential mode operating range of ±120 V. The high common-mode input impedance makes the device well suited for high voltage measurements across a shunt resistor. The buffer amplifiers
inverting input is available for making a remote Kelvin connection.
A precision 10 k resistor connected to an external pin is provided for either a low-pass filter or to attenuate large
differential input signals. A single capacitor implements a low-pass filter. The AD628 operates from single and dual supplies and is available in an 8-lead SOIC or MSOP package. It operates over the standard industrial temperature range of -40 to +85
