TS27L2IDT

Instrumentation, Op Amps, Buffer Amps Overview

The TS27L2IDT is a dual precision low-power CMOS operational amplifier manufactured by STMicroelectronics. It features a gain bandwidth product of 100 kHz and a slew rate of 40 mV/µs. The device operates within a supply voltage range of 3 V to 16 V or ±1.5 V to ±8 V. Key electrical characteristics include an input bias current of 1 pA, an input offset voltage of 1.1 mV, and a quiescent current of 10 µA per amplifier. It provides a common-mode rejection ratio of 65 dB and supports output currents up to 45 mA.

Instrumentation, Op Amps, Buffer Amps Feature Summary

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'IDT' against the manufacturer datasheet to confirm package type (typically TSSOP-8) and industrial temperature rating. Ensure the ordering code matches the required pin configuration and thermal performance specifications for your design.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when ultra-low static current is critical alongside moderate precision requirements. It serves as a lower-power alternative to standard CMOS op-amps while offering better temperature stability than JFET types. Consider the trade-off between its 100 kHz bandwidth and power efficiency.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the TS27L2 series, which represents the very low power variant of ST's CMOS operational amplifiers. It shares architectural similarities with the TS27M2 and TS272 families but is optimized specifically for minimal energy usage at 10 µA per channel.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Compatible alternatives within the same family include TS27L2CDT and TS27L2CPT. Verify that substitute packages match the physical footprint and pinout requirements of the existing design.
