概述
Description
OPA4130UA is a Texas Instruments operational amplifier in the OPA4130 family. It’s a precision, general‑purpose op‑amp designed for reliable amplification in single‑ or dual‑supply analog circuits that require low offset, low bias current and low noise. The UA suffix denotes the packaging/temperature variant (typically an 8‑pin MSOP/SOIC with industrial grade tolerance). Key characteristics you’ll typically see include low input offset voltage and drift, low input bias current, and solid gain‑bandwidth/slew characteristics suitable for instrumentation, sensor conditioning, active filters, and DAC/ADC driver stages. It supports standard feedback configurations and moderate capacitive loads. For exact electrical specifications—supply range, input/output voltage ranges, GBW, slew rate, noise, and packaging—consult the latest TI OPA4130UA datasheet and product page.
Equivalent
Direct equivalents depend on the required specs (GBW, slew rate, input/output swing, noise, supply, package). Do you need pin‑for‑pin substitutes? If yes, please share operating voltage and performance needs; otherwise use TI’s Cross-Reference tool to find exact matches.
