TS942IDT

Instrumentation, Op Amps, Buffer Amps Overview

The TS942IDT is a dual micropower operational amplifier from STMicroelectronics, characterized for single-supply operation between 2.5 V and 10 V over an industrial temperature range of -40°C to +85°C. It features a gain-bandwidth product of 10 kHz, a slew rate of 4.5 V/µs, and a typical input bias current of 1 pA. The device draws 1.2 µA of supply current per channel and provides rail-to-rail output swing with a maximum output current of 650 µA. Key electrical parameters include a 10 mV input offset voltage, 60 dB common-mode rejection ratio, and CMOS inputs housed in an SOIC-8 surface-mount package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix IDT against the manufacturer's official datasheet to confirm the SOIC-8 package type and tape-and-reel delivery format. Ensure the component meets RoHS compliance requirements as specified in the latest documentation. Cross-reference the part number with authorized distributors to confirm active status and availability, as manufacturing updates may affect ordering details.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing circuits that require minimal quiescent current alongside rail-to-rail output performance. The 10 kHz bandwidth suits low-frequency applications such as sensor signal amplification or battery monitoring. Verify that the 650 µa output drive capability meets load requirements and that the 10 mV offset voltage is acceptable for the application's precision needs.

Instrumentation, Op Amps, Buffer Amps Part Context

The TS942IDT belongs to the TS94x series of operational amplifiers, which includes single, dual, and quad variants. This family is designed for ultra-micropower applications, offering consistent performance across different channel counts while maintaining low power consumption and rail-to-rail output characteristics suitable for portable and battery-operated electronics.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consult official substitution guides for compatible parts within the TS94x series or other STMicroelectronics micropower op-amps. Verify pin compatibility and electrical parameter equivalence before replacing.
