Product details

Active production — no LTB clock ticking

The OPA336UA/2K5: ROHS3 compliant — no exemption conflicts for EU or California market shipments. The part carries full TI factory traceability through the standard supply chain.

100 kHz GBW, 20 µA — the micropower signal-conditioning sweet spot

100 kHz gain-bandwidth product means the closed-loop gain is flat within 0.1 dB up to roughly 10 kHz — this covers audio-band filtering, sensor amplification below 1 kHz, and slow ADC driver stages. Above 10 kHz the open-loop gain drops below 20 dB, so a 20 kHz signal sees only 14 dB of loop gain and the distortion rises. 20 µA quiescent supply current puts this squarely in the micropower class — a battery-powered sensor node drawing 20 µA from a CR2032 runs over a year continuously. The 5 mA output current per channel is enough to drive a 10 kΩ load rail-to-rail or a 2.5 V reference input on a SAR ADC, but not a headphone or relay coil. Rail-to-rail output swing gives the full supply dynamic range into a light load — critical when running from a 2.5 V rail where every millivolt of headroom matters. The 60 µV typical input offset voltage is adequate for 8-bit and most 10-bit systems; for 12-bit or better, budget an auto-zero or chopper-stabilized part. 1 pA typical input bias current lets this op-amp sit directly on a high-impedance source — a 10 MΩ photodiode or a pH probe sees less than 10 µV of offset from bias current alone. No external JFET buffer needed for most sensor front-ends.

2.3 V to 5.5 V supply — single-rail flexibility

The supply span runs from 2.3 V minimum to 5.5 V maximum — this covers a single Li-ion cell (3.0-4.2 V), a 3.3 V regulated rail, or a 5 V USB bus. No external regulator needed if the rail is within that window. Industrial temperature range -40°C to 85°C covers most factory-floor enclosures, outdoor telecom cabinets, and automotive cabin applications. Not rated for under-hood or 125°C engine-bay environments. 8-SOIC package, 3.90 mm width — industry-standard footprint shared by thousands of single op-amps. Drops into existing PCB layouts without a board spin for most single-channel positions. The 0.154-inch body height fits standard SOIC sockets if prototyping.
