AD8205:  Single Supply 42V System Difference Amplifier

Product Description

The AD8205 is a high-performance, single-supply difference amplifier with a wide input common mode voltage (CMV) operational range of -2 V to 65 V, which allows the chip to measure small differential voltages--such as across a shunt resistor--in the presence of high voltages (large CMV). Additionally, the device can survive over an input CMV range of -5 V to 70 V. Excellent dc performance over temperature keeps errors in the measurement loop to a minimum. Offset drift is less than 20 microV/degrees C, and gain drift is below 20 ppm/degrees C (up to 125 degrees C). The AD8205 also has very high common-mode rejection of 80 dB, which extends from dc up to 100 kHz. The part’s ability to reject high, common mode voltages while reading small differential voltages eliminates error sources commonly associated with current sensing in electro-mechanical systems. The AD8205 also is well suited for industrial applications that measure small differential voltages in the presence of high CMV. Many industrial current sensing applications, such as hydraulic systems and motor control, already require this extended CMV range.
