That figure — an order of magnitude below a standard LM358's quiescent draw — makes this part the choice for battery-powered sensor conditioning, portable instrumentation, and always-on signal chains where every microamp on the rail is budgeted. The 100 kHz gain-bandwidth product and 0.04 V/µs slew rate are consistent with the micropower design: you trade speed for current. Input bias current is 1 pA typical, which suits high-impedance sources like photodiode or pH probe front-ends without needing a separate JFET buffer. ## Package and footprint Housed in an 8-SOIC package with 0.154-inch body width, surface-mount only. The supplier device package is 8-SOIC. Standard SOIC-8 land pattern applies; no exposed pad to route. Shipping options include Tape & Reel and Cut Tape. ## Lifecycle and compliance ROHS3 compliant.","metaTitle":"STMicro TS271CDT CMOS Op-Amp, 100 kHz, 10 µA Supply","metaDescription":"TS271CDT is a single general-purpose CMOS op-amp with 100 kHz GBW, 10 µA supply current, 1 pA input bias, 0.04 V/µs slew rate.

However, the TS271CDT's 100 kHz GBW and 0.04 V/µs slew rate are significantly slower than the LM358's 1 MHz / 0.3 V/µs — verify the bandwidth budget before substituting. Both are single-supply op-amps in the same SOIC-8 footprint, but the TS271CDT is a CMOS input stage (1 pA bias) versus the LM358's bipolar input (45 nA bias)."},{"question":"What is TS271CDT's closest functional second-source?","answer":"The TS27L4CDT is a quad-channel version with the same parametric core. Neither is a pin-compatible replacement for the single-channel TS271CDT, but they share the same micropower CMOS architecture and can serve as a design-in alternative if channel count or temperature range requirements change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/TS271CDT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/TS271CDT when reusing this data.
