The primary function is to amplify the voltage difference between two input signals while rejecting signals that are common to both inputs. This allows it to extract the differential signal from noise and interference.
Typical supply voltage is dual DC supply ranging from ±5 V to ±15 V. This dual supply is necessary for true differential operation, allowing the output to swing both positive and negative.
The differential voltage gain is set by external resistors connected to the amplifier. The gain range is typically 20 to 60 dB, depending on the resistor values chosen for the specific application.
CMRR indicates the ability to reject common-mode signals, which are signals present equally on both inputs. A higher CMRR (80-120 dB) means better rejection of common-mode noise, improving signal integrity.
