GENERAL DESCRIPTION

The AMP04 is a single-supply instrumentation amplifier designed to work over a +5 volt to ±15 volt supply range. It offers an excellent combination of accuracy, low power consumption, wide input voltage range, and excellent gain performance.

Gain is set by a single external resistor and can be from 1 to 1000. Input common-mode voltage range allows the AMP04 to handle signals with full accuracy from ground to within 1 volt of the positive supply. And the output can swing to within 1 volt of the positive supply. Gain bandwidth is over 700 kHz. In addition to being easy to use, the AMP04 draws only 700 µA of supply current.

For high resolution data acquisition systems, laser trimming of low drift thin-film resistors limits the input offset voltage to under 150 µV, and allows the AMP04 to offer gain nonlinearity of 0.005 and a gain tempco of 30 ppm/°C.

A proprietary input structure limits input offset currents to less than 5 nA with drift of only 8 pA/°C, allowing direct connection of the AMP04 to high impedance transducers and other signal sources.
