What this dual op amp is and where it fits
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. The rail-to-rail output stage lets it swing close to the supply rails, useful when running from a 2.5 V to 10 V single supply. 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
Housed in an 8-SOIC (0.154" body width) with a surface-mount footprint, the TS942AIDT is hand-solderable with a fine-tip iron — no hot-air required. The -40°C to 85°C operating range covers industrial enclosures, outdoor telecom cabinets, and factory-floor sensor heads. 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.
