Description
OPA378AIDCKR is a Texas Instruments operational amplifier. It’s a high-precision, low-noise, low-offset/low-drift single-channel op-amp designed for accurate DC and low-frequency signal conditioning. The device is well suited for instrumentation, sensor front ends, transimpedance applications, and ADC/DAC buffering, where tiny signal levels must be amplified with minimal error. The AIDCKR suffix indicates packaging and handling: RoHS-compliant 8-pin surface-mount packaging (MSOP/VSSOP family) with tape-and-reel options. Key takeaways: very low input offset and drift, low input bias current, good DC accuracy, and stable closed-loop performance. For exact electrical specs, operating ranges, and package details, consult the TI datasheet or product page.
Equivalent
Equivalent substitutes depend on the required specs (offset, drift, bandwidth, supply). Close TI options to consider: OPA333 (zero-drift RRIO), OPA2333 (dual zero-drift RRIO), OPA2365 (RRIO, low-noise), OPA2277 (zero-drift). Analog Devices equivalents: ADA4528-1/ADA4528-2 (zero-drift RRIO). For an exact cross-reference, use TI’s Cross-Reference tool.
