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 con-

sumption, 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 addi-

tion 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 con-

nection of the AMP04 to high impedance transducers and

other signal sources.

The AMP04 is specified over the extended industrial (–40

°C to

+85

°C) temperature range. AMP04s are available in plastic and

ceramic DIP plus SO-8 surface mount packages.
