4、ionPrecision Single Supply Instrumentation AmplifierGENERAL 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 gai
5、n 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 bandwid
6、th is over 700 kHz. In addi- tion to being easy to use, the AMP04 draws only 700 A 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 V, and allows the AMP04 to offer gain nonlinearity of 0.00
7、5% 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.The AMP04 is specified over
