Key Features
- 40 V wide supply range with rail-to-rail input and output enables direct interfacing with high-voltage industrial sensors without additional level-shifting circuitry
- 115 dB typical CMRR with only 1.5 mV maximum offset voltage delivers precision signal conditioning in 4–20 mA loop transmitters and bridge sensor circuits
- Four independent amplifiers in a single 14-pin SOP package reduce BOM count and PCB area by up to 4× compared with discrete single op amp solutions
Applications
The POPA4990IPWR is well-suited for industrial process-control transmitters and PLCs where all four channels can amplify 4–20 mA sensor signals from pressure, temperature, or flow transducers operating up to 40 V. Its rail-to-rail output and low offset voltage make it a strong candidate for precision instrumentation front ends in medical monitoring equipment and test-and-measurement instruments. The wide supply range also covers automotive infotainment and body-electronics analog signal chains that must operate reliably across 12 V to 36 V battery transients.

Frequently Asked Questions
What is the gain-bandwidth product of the POPA4990IPWR, and for which signal-frequency applications is it sufficient?
The POPA4990IPWR has a 1 MHz gain-bandwidth product, which is adequate for DC to audio-frequency signal conditioning tasks such as amplifying sensor outputs up to 10 kHz at unity gain or up to 1 kHz at a closed-loop gain of 100 V/V in industrial transmitter applications.
How does the POPA4990IPWR's 40 V supply range benefit designs powered from an unregulated 24 V industrial rail?
A 40 V maximum supply rating provides at least 16 V headroom above a 24 V nominal rail, accommodating load-dump spikes and supply transients without clamping or over-voltage damage—eliminating external protection components that would otherwise be needed with 36 V-rated op amps in industrial automation cabinets.
What input offset voltage does the POPA4990IPWR specify, and how does it affect 4–20 mA loop accuracy?
The maximum input offset voltage is 1.5 mV, which translates to a worst-case output error of 1.5 mV × gain in a 4–20 mA transmitter. At a gain of 10, this is 15 mV or less than 0.1% of a 12 V span, meeting the accuracy requirements of most Class B industrial instruments.
How does integrating four op amps in the POPA4990IPWR reduce system cost compared with using four discrete single-channel devices?
Using one 14-pin SOP package instead of four individual single-channel packages cuts component count by 3, reduces soldering joints from 16 to 14 pins total, and shrinks the PCB footprint by roughly 60%—directly lowering assembly cost and improving reliability in multi-channel sensor interface boards.
