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 sup- ply 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.
*Protected by U.S. Patent No. 5,075,633.
