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
μ
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
μ
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 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 the extended industrial (–40
°
C to
+85
°
C) temperature range. AMP04s are available in plastic and
ceramic DIP plus SO-8 surface mount packages.
