At 45 µA for all four amplifiers, each channel consumes roughly 11.25 µA. This micropower profile suits always-on monitoring loops, portable medical devices, and remote sensor nodes where every microamp extends battery life. The 10 mA output drive per channel is enough to swing into a typical ADC input or drive a modest load, but not a headphone or relay coil. ## Supply range and single-supply operation The rail-to-rail output stage lets the signal swing close to the supply rails, preserving dynamic range in low-voltage systems. Input common-mode range extends to the negative rail but stops about 1 V below the positive rail — a typical CMOS limitation that matters for high-side current sensing at 3.3 V. Expect this part in factory automation I/O modules, engine bay sensor conditioners, and outdoor telecom line cards where the ambient temperature swings wide. Housed in a 14-TSSOP (4.40 mm width, 0.173\" pitch), the OPA4348AIPWT is a surface-mount device. The fine-pitch leads require careful PCB layout — 0.65 mm pitch typical for TSSOP — and a stencil designed for the 0.25 mm lead width.","metaTitle":"OPA4348AIPWT CMOS quad op-amp, 1 MHz GBW, 45 µA supply","metaDescription":"TI OPA4348AIPWT quad CMOS rail-to-rail op-amp, 1 MHz GBW, 0.5 V/µs slew rate, 45 µA supply, 2.1-5.5 V, -40 to 125°C, 14-TSSOP.

The supply voltage range is 2.1 V to 5.5 V, so a 3.3 V single rail is well within the operating window. The rail-to-rail output stage maintains signal swing near the rails."},{"question":"What is the cross-reference or equivalent for OPA4348AIPWT?","answer":"The closest functional equivalent in the same quad CMOS family is the OPA4374AIPWT. It offers a higher gain-bandwidth of 6.5 MHz and a 5 V/µs slew rate, but requires a minimum supply of 2.7 V and draws 600 µA per channel — a trade-off of speed versus power. The OPA4348 is the lower-power, lower-bandwidth option."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/OPA4348AIPWT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/OPA4348AIPWT when reusing this data.
