Input bias current is a CMOS-typical 1 pA, so it won't load high-impedance sensors. That's fine for audio, sensor conditioning, and low-speed control loops, but not for video or fast ADC drivers. The 1 MHz gain-bandwidth product supports gains up to 100 with a 10 kHz closed-loop bandwidth — adequate for most precision analog front-ends. If you need to drive a 10-bit ADC at 100 kSPS, the settling time from this amplifier will be the bottleneck; consider a faster part like the TLV9351 (3.5 MHz, 20 V/µs) for that role.","metaTitle":"Texas Instruments OPA705PA Op Amp, 1 MHz, Rail-to-Rail","metaDescription":"OPA705PA general-purpose op amp: 1 MHz GBW, 0.6 V/µs slew rate, rail-to-rail output, 160 µA supply, 1 pA bias.

The rail-to-rail output stage and 4 V to 12 V supply span make it well-suited for single-supply operation from a 5 V or 12 V rail. The input common-mode range does not extend to the positive rail — it stops about 1.1 V below V+ — so for high-side sensing at 3.3 V single supply, look at a true rail-to-rail input amplifier instead."},{"question":"Can OPA705PA replace a failed OPA703PA?","answer":"The OPA705PA and OPA703PA share the same pinout (standard single op-amp DIP-8) and both are general-purpose CMOS amplifiers with rail-to-rail output. The OPA703PA has a 1 MHz GBW and 0.6 V/µs slew rate — identical to the OPA705PA. If your circuit uses a 5 V rail or higher, the OPA705PA is a direct drop-in replacement. For 3.3 V or 2.7 V rails, the OPA703PA remains the correct choice."},{"question":"What is the slew rate of OPA705PA?","answer":"0.6 V/µs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/OPA705PA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/OPA705PA when reusing this data.
