AMP04
Features:
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 uA of supply
current.
For high resolution
data acquisition systems, laser trimming of
low drift
thin-film resistors limits the input offset voltage to
under 150
mV, 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.
