Product details

The Texas Instruments OPA2703UA is a dual CMOS operational amplifier with rail-to-rail output, packaged in an 8-SOIC. It delivers a gain-bandwidth product of 1 MHz and a slew rate of 0.6 V/µs, drawing just 160 µA per channel. The CMOS input stage keeps input bias current at 1 pA, making it a fit for high-impedance sensor conditioning, battery-monitoring circuits, and general-purpose signal chains in industrial control and instrumentation.

Supply range and output drive

The part operates from a single supply spanning 4 V to 12 V. Each channel can source or sink 10 mA.

Frequently asked questions

Is OPA2703UA a dual op amp?

Yes, it contains two independent CMOS op-amp circuits in a single 8-SOIC package.

What is the output type of OPA2703UA?

Rail-to-rail output, meaning the output voltage can swing within millivolts of both supply rails — useful for low-voltage single-supply designs.

What is the closest functional equivalent to OPA2703UA?

The OPA4374AIPWT is a quad CMOS rail-to-rail op-amp with higher slew rate (5 V/µs) and bandwidth (6.5 MHz), wider temperature range (-40°C to 125°C), and a TSSOP-14 package. It is a functional upgrade but requires a different footprint and four channels.
