The AMP01 is a monolithic instrumentation amplifier designed
for high-precision data acquisition and instrumentation applica-
tions. The design combines the conventional features of an
instrumentation amplifier with a high current output stage. The
output remains stable with high capacitance loads (1
µF),
a
unique ability for an instrumentation amplifier. Consequently,
the AMP01 can amplify low level signals for transmission
through long cables without requiring an output buffer. The output
stage may be configured as a voltage or current generator.
Input offset voltage is very low (20
µV),
which generally elimi-
nates the external null potentiometer. Temperature changes
have minimal effect on offset; TCV
IOS
is typically 0.15
µV/°C.
Excellent low-frequency noise performance is achieved with a
minimal compromise on input protection. Bias current is very
low, less than 10 nA over the military temperature range. High
common-mode rejection of 130 dB, 16-bit linearity at a gain of
1000, and 50 mA peak output current are achievable simulta-
neously. This combination takes the instrumentation amplifier
one step further towards the ideal amplifier.
AC performance complements the superb dc specifications. The
AMP01 slews at 4.5 V/µs into capacitive loads of up to 15 nF,
settles in 50
µs
to 0.01% at a gain of 1000, and boasts a healthy
26 MHz gain-bandwidth product. These features make the
AMP01 ideal for high speed data acquisition systems.
Gain is set by the ratio of two external resistors over a range of
0.1 to 10,000. A very low gain temperature coefficient of
10 ppm/°C is achievable over the whole gain range. Output
voltage swing is guaranteed with three load resistances; 50
Ω,
500
Ω,
and 2 kΩ. Loaded with 500
Ω,
the output delivers
±
13.0 V minimum. A thermal shutdown circuit prevents de-
struction of the output transistors during overload conditions.
The AMP01 can also be configured as a high performance op-
erational amplifier. In many applications, the AMP01 can be
used in place of op amp/power-buffer combinations.
