AMP02

The AMP02 is the first precision instrumentation amplifier available in an 8-pin package. Gain of the AMP02 is set by a single external resistor, and can range from 1 to 10,000. No gain set resistor is required for unity gain. The AMP02 includes an input protection network that allows the inputs to be taken 60 V beyond either supply rail without damaging the device.

Laser trimming reduces the input offset voltage to under 100 mV.Output offset voltage is below 4 mV and gain accuracy is better than 0.5% for gain of 1000. PMI's proprietary thin-film resistor process keeps the gain temperature coefficient under 50 ppm/°C. Due to the AMP02's design, its bandwidth remains very high over a wide range of gain. Slew rate is over 4 V/ms making the AMP02 ideal for fast data acquisition systems.

A reference pin is provided to allow the output to be referenced to an external dc level. This pin may be used for offset correction or level shifting as required. In the 8-pin package, sense is internally connected to the output.
