The LTC1053CSW#PBF is a quad precision zero-drift operational amplifier from Analog Devices (formerly Linear Technology) using chopper stabilization to achieve 5uV max offset voltage and 0.05uV\/C drift. With only 1.5uA supply current per amplifier and operation from single 4.75V to 15.5V supplies, it is ideal for precision low-power applications.<\/p>\n

With ultra-low 1.5uA supply current per amplifier and 5pA input bias current, this device is optimized for precision low-power applications such as medical instrumentation, strain gauge amplification, and thermocouple signal conditioning. The internal chopper circuit operates continuously without requiring an external clock.","working_principle":"The LTC1053 uses a chopper-stabilized architecture where the main amplifier is continuously auto-zeroed by an auxiliary nulling amplifier. The nulling amplifier periodically measures and cancels the offset of the main amplifier, effectively reducing the offset voltage to near zero. This auto-zeroing cycle occurs at an internal clock frequency, and since the process is continuous, the offset drift is virtually eliminated. The result is a DC precision amplifier with microvolt-level offset that does not degrade over temperature or time.","pin_description":"
