Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape-and-reel quantity. Ensure the design accounts for moisture sensitivity levels and recommended storage conditions. Confirm that the selected variant meets the required operating temperature range for the intended environment.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the OPA2202ID when high DC accuracy and stability with large capacitive loads are required. Compare its 1.5 µV/°C drift against other family members like the OPA202 if lower drift is critical. Consider the 8-pin SOIC footprint constraints and verify that the 36 V maximum supply voltage aligns with system power rails.

Instrumentation, Op Amps, Buffer Amps Part Context

The OPA2202 belongs to the OPAx202 series, which utilizes TI's precision super-beta complementary bipolar process. This technology enables exceptional linearity and low flicker noise. The OPA2202 specifically targets applications needing robust performance with heavy capacitive loads without phase inversion, distinguishing it from standard general-purpose amplifiers.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The datasheet explicitly states that the OPAx202 series replaces OP-07 and OP-27 amplifiers. Designers transitioning from these legacy parts should verify pin compatibility and ensure that the new bias current and noise specifications meet the circuit requirements.
