AM417 – Ratiometric instrumentation
amplifier with adjustable output stage
PRINCIPLE FUNCTION
Integrated instrumentation amplifier with an output stage for the amplification of differential
signals and with an internal current source for the supply of external signal sources. The
output signal is a voltage between 0.5 and 4.5V, ratiometrical to the supply voltage. The
output span could be adjusted by the changeable gain of the output stage.
