Product details

The STMicroelectronics TS942AIDT is a dual general-purpose operational amplifier in an 8-SOIC package. It delivers a gain-bandwidth product of 10 kHz while drawing just 1.2 µA total supply current across both channels — one of the lowest power draws in the TS94x family. With an input bias current of 1 pA and an input offset voltage of 5 mV, it is built for slow, precision signals where battery life matters more than speed.

Package, temperature grade, and lifecycle

Lifecycle status is active, and the part is ROHS3 compliant. No end-of-life notice is on record, so it is safe to qualify for new production BOMs.

Frequently asked questions

Can TS942AIDT be used in battery-powered circuits?

Yes, the 1.2 µA total supply current and 2.5 V minimum supply make it well suited for battery-powered sensor conditioning and always-on monitoring.

What are the TS942AIDT equivalents?

The TSV621ICT is a single-channel micropower op amp with a 420 kHz bandwidth and 0.14 V/µs slew rate — faster but single-channel. The TSV912IDT is a dual-channel automotive-grade (AEC-Q100) op amp with 8 MHz bandwidth and 4.5 V/µs slew rate, drawing 800 µA supply. Neither is a direct pin-for-pin replacement; the TS942AIDT is the lowest-power dual option in this footprint.
