With an input offset voltage of 40 µV and a supply current of 445 µA per amplifier, this part targets precision signal conditioning where low drift and low power are both required. The OPA2145IDR operates from a single supply as low as 4.5 V up to 36 V, or from dual supplies of ±2.25 V to ±18 V.","metaTitle":"TI OPA2145IDR JFET Op-Amp, 5.5 MHz, Rail-to-Rail Output","metaDescription":"Texas Instruments OPA2145IDR dual JFET op-amp: 5.5 MHz GBW, 2 pA bias, 40 µV offset, rail-to-rail output, -40°C to 125°C.

This is particularly useful in low-voltage single-supply applications where maximizing signal swing is critical."},{"question":"Can OPA2145IDR replace OPA2134?","answer":"The OPA2145IDR is a newer dual JFET op-amp from TI with a 5.5 MHz GBW, 2 pA bias, and 40 µV offset, compared to the OPA2134's 8 MHz GBW and 5 pA bias. Both are dual JFET types in 8-SOIC, but the OPA2145IDR offers lower offset and bias at the expense of slightly lower bandwidth. Pin compatibility should be verified against the specific OPA2134 package variant before substitution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/OPA2145IDR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/OPA2145IDR when reusing this data.
