GENERAL DESCRIPTION

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

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 AMP02’s design, its bandwidth remains very high

over a wide range of gain. Slew rate is over 4 V/

µs 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 correc-

tion 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 AMP01 data sheet. For the highest input impedance

and speed, consult the AMP05 data sheet.
