The invention provides a sensor reading circuit. The sensor reading circuit comprises a chopper switch array, a multi-input interface, an operational amplifier, a feedback network, a temperature drift correction circuit, a chopper switch, a lowpass filter, a digital control logic circuit and an oscillator. According to the circuit, temperature drift coefficients of resistors are corrected through utilization of the temperature drift correction circuit; input differential voltages are amplified through utilization of a folding cascade amplifier; the application amount of the resistors can be reduced; a resistor mismatch probability among branches is reduced; reading signal errors are reduced; and chip costs are reduced.
