GENERAL DESCRIPTION
The AMP04 is a single-supply instrumentation amplifier ceramic DIP plus SO-8 surface mount packages. designed to work over a +5 volt to ± 15 volt supply range. It Contact your local sales office for MIL-STD-883 data sheet offers an excellent combination of accuracy, low power con- and availability. sumption, wide input voltage range, and excellent gain performance.
PIN CONNECTIONS
Gain is set by a single external resistor and can be from 1 to

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.
