T he AMP02 is the first precision instrumentation amplifier
available in an 8-pin package. Gain of the AMP02 is set by a
single external resistor, and can range from 1 to 10,000. No
gain set resistor is required for unity gain. T he AMP02 includes
an input protection network that allows the inputs to be taken
60 V beyond either supply rail without damaging the device.
Laser trimming reduces the input offset voltage to under 100
μ
V.
Output offset voltage is below 4 mV and gain accuracy is better
than 0.5% for gain of 1000. PMI’s proprietary thin-film resistor
process keeps the gain temperature coefficient under 50 ppm/
°
C.
Due to the AMP02’s design, its bandwidth remains very high
over a wide range of gain. Slew rate is over 4 V/
μ
s making the
AMP02 ideal for fast data acquisition systems.
A reference pin is provided to allow the output to be referenced
to an external dc level. T his pin may be used for offset correc-
tion or level shifting as required. In the 8-pin package, sense is
internally connected to the output.
For an instrumentation amplifier with the highest precision,
consult the AMP01 data sheet. For the highest input impedance
and speed, consult the AMP05 data sheet.
