Product details

Quad CMOS op-amp for multi-channel signal conditioning

The Texas Instruments OPA4743EA is a quad-channel CMOS operational amplifier with a 7 MHz gain-bandwidth product and rail-to-rail output stage, packaged in a 14-TSSOP. It delivers a 10V/µs slew rate while drawing just 1.1 mA per channel, making it a fit for multi-channel sensor interfaces, active filters, and data-acquisition front-ends where board space and power budget are tight.

The supply span runs from 3.5 V minimum to 12 V maximum. Each of the four outputs can source or sink 20 mA.

The 14-TSSOP package is a fine-pitch surface-mount footprint — 4.40 mm body width — so plan for standard reflow profiling and a visual inspection step under magnification.

Frequently asked questions

What is an alternative equivalent to OPA4743EA?

The OPA4374AIPWT is a close functional alternative — also a quad CMOS rail-to-rail output op-amp in a TSSOP package. Pin compatibility should be verified against the specific footprint.
