Product details

10 µA supply current — the micropower anchor

The TS271CDT is a single-channel CMOS general-purpose op-amp from STMicroelectronics whose headline number is the 10 µA typical supply current. 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. 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.

Standard SOIC-8 land pattern applies; no exposed pad to route. Shipping options include Tape & Reel and Cut Tape.

ROHS3 compliant.

Frequently asked questions

Can TS271CDT replace an LM358 in a low-power design?

The TS271CDT draws 10 µA supply current versus the LM358's ~500 µA typical, so it is a direct drop-in for battery-powered applications where the LM358's quiescent draw is too high. 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).

What is TS271CDT's closest functional second-source?

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.
