AMP04s are available in plastic and GENERAL DESCRIPTION ceramic DIP plus SO-8 surface mount packages. The AMP04 is a single-supply instrumentation amplifier 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 8-Lead Epoxy DIP 8-Lead Narrow-Body SO 1000. Input common-mode voltage range allows the AMP04 to (P Suffix) (S Suffix) 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 R 1 8 R GAIN GAIN R R GAIN GAIN the positive supply. Gain bandwidth is over 700 kHz.

V 4 5 REF V REF For high resolution data acquisition systems, laser trimming of low drift thin-film resistors limits the input offset voltage to under 150 V, 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.
