Přehled produktu
AD628 is a precision difference amplifier. It 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. The device has an input common mode and differential mode operating range of ±120V. The high common mode, input impedance makes the device well suited for high voltage measurements across a shunt resistor. The inverting input of the buffer amplifier is available for making a remote kelvin connection. It is used in application such as high voltage current shunt sensing, programmable logic controllers, analogue input front end signal conditioning +5V, +10V, ±5V, ±10V, and 4 to 20mA, isolation, sensor signal conditioning, power supply monitoring, electrohydraulic controls, motor controls etc.
