说明

产品概览

The OP07CSZ from Analog Devices is an ultralow offset voltage precision operational amplifier in an 8-lead SOIC package. With a maximum input offset voltage of 75µV (OP07E grade) and drift of 1.3µV/°C, it has become an industry standard for high-gain instrumentation applications. The device operates over a wide supply range of ±3V to ±18V and offers outstanding long-term stability of 1.5µV/month maximum.

The OP07CSZ is a precision operational amplifier from Analog Devices featuring ultralow input offset voltage achieved through wafer-level trimming. The OP07C grade specified over -40°C to +85°C offers typical offset voltage of 60µV and maximum CMRR of 120dB. The device eliminates the need for external nulling in most applications, simplifying circuit design. Its combination of low offset, low drift, high open-loop gain, and excellent CMRR makes it particularly suited for high-gain instrumentation where DC accuracy is critical. The wide ±3V to ±18V supply range and ±14V input voltage range provide flexibility in various signal conditioning applications.

The OP07 employs a chopperless bipolar-input transistor amplifier circuit to achieve low offset and long-term stability without the switching noise associated with chopper-stabilized designs. Input offset voltage is trimmed at wafer level using electronically adjusted on-chip resistors (R2A/R2B), reducing VOS to 75µV maximum for the E grade. The bias-current cancellation circuitry provides low input bias current (±4nA for OP07E) while maintaining the low 1/f noise corner frequency characteristic. The true differential input with wide common-mode range and high CMRR (106dB OP07E) ensures maximum flexibility in noninverting configurations. The output stage drives loads directly without external buffering.

  • Thermocouple Signal Conditioning: Amplifies microvolt-level thermocouple outputs with minimal offset error, eliminating need for frequent recalibration in temperature measurement systems
  • Strain Gauge Bridge Amplifiers: Provides high-gain amplification of Wheatstone bridge outputs in load cells and pressure sensors with excellent DC accuracy
  • Shunt Current Measurement: Senses low-side current through shunt resistors with 120dB CMRR rejecting common-mode bus voltage variations
  • Precision Active Filters: Constructs low-frequency Sallen-Key or MFB filters where DC offset directly impacts filter accuracy
  • RTD Signal Conditioning: Amplifies PT100/PT1000 RTD signals with drift performance that maintains measurement accuracy over temperature
