Working Principle

The OP275GSZ-REEL is a wide-band, single-supply, switched-capacitor op amp, specifically designed for low-noise instrumentation and high-resolution applications. The device incorporates an Op Amp configured in a common-mode feedback loop. The Op Amp in the feedback loop amplifies the differential input signal and compares it to the reference level. The difference between the two signals is then converted to a control signal for the switching transistor that controls the current flow to and from the input pins.The Op Amp senses the input signal at both of its inputs and amplifies the difference between the two levels. The amplified signal is then supplied to the output of the Op Amp. This output voltage is then compared to the reference level, which sets the gain of the amplifier. The comparison signal is then used to control the switching transistor, which provides a low-impedance path to the input pins and allows a regulated flow of current between them. This regulated current flow is used to link the input and output terminals, allowing signal data to be transmitted between them.

Conclusion

The OP275GSZ-REEL is a versatile, low-noise single-supply op amp specifically designed for instrumentation and high-resolution applications. The device offers wide bandwidth, low offset voltage, and eight matched input pairs in a lead-free, thermally-enhanced package. Additionally, it is capable of extended temperature operation and offers excellent common-mode and power supply rejection ratio. The device has a wide range of applications and is suitable for motor control, medical instrumentation, automotive, digital audio, and industrial control systems. The device incorporates an Op Amp configured in a common-mode feedback loop and is capable of regulating the current flow between the input and output pins.
