Quad CMOS op-amp in a compact 14-TSSOP
The Texas Instruments OPA4374AIPWT packs four CMOS op-amp channels into a 14-TSSOP package, each rail-to-rail on the output. It runs on a single 2.7 V to 5.5 V supply and draws 585 µA total quiescent across all four amplifiers. With a gain-bandwidth product of 6.5 MHz and a 5 V/µs slew rate, this part handles signal conditioning up into the low-MHz range — think anti-aliasing filters, ADC drivers, or piezo sensor amplifiers. The CMOS input stage keeps input bias current down at 0.5 pA, so high-impedance sources like photodiodes or pH probes won't see loading errors. Output can swing within millivolts of either rail, preserving dynamic range in low-voltage systems. Temperature range spans -40°C to 125°C, so it's comfortable in industrial cabinets, outdoor telecom enclosures, or under-hood automotive modules that see thermal cycling. The 14-TSSOP footprint is a common quad-op-amp layout; board space is tight but the 4.40 mm body width fits on dense mixed-signal PCBs.
Supply range and power budget
The supply span of 2.7 V to 5.5 V covers the two most common single-rail logic voltages. Total quiescent of 585 µA for all four channels is the number to budget in your power tree. Output current per channel is rated at 5 mA.
Lifecycle and sourcing
TI lists the OPA4374AIPWT as Active and ROHS3 compliant. No NRND or last-time-buy flags, which means it is still a valid choice for new designs and production BOMs. Sourcing runs through independent distribution; availability and current pricing are confirmed at quote time against an RFQ.
