The AMP-02 is the first precision instrumentation amplifier available in an 8-pin package. Gain of the AMP-02 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 AMP-02 includes an input protection network that allows the inputs to be taken 60V beyond either supply rail without damaging the device.
Laser trimming reduces the input offset voltage to under 100 µV. 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 AMP-02's design, its bandwidth remains very high over a wide range of gain. Slew rate is over 4V/µS making the AMP-02 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.
For an instrumentation amplifier with the highest precision, consult the AMP-01 data sheet.
