Working Principles

The LTC1152CS8#TRPBF is a precision instrumentation amplifier designed to amplify and condition weak signals for accurate measurement. It utilizes a differential input stage to amplify the voltage difference between the non-inverting (IN1) and inverting (IN2) inputs. The gain of the amplifier can be adjusted by external resistors connected to the IN1 and IN2 pins.

The amplified signal is then filtered and output through the OUT pin. The REF pin provides a reference voltage for the amplifier's internal circuitry. The V+ and V- pins supply power to the IC, while the GND pin serves as the ground connection.
