Key Features
- 40 V supply rating with 4.5 MHz gain-bandwidth product suits high-voltage industrial measurement front-ends
- 130 dB typical CMRR and 750 µV maximum input offset voltage deliver precision performance in differential signal chains
- Rail-to-rail input and output in a compact 8-pin SOT-23 package minimizes PCB footprint in dual-channel amplifier stages
Applications
The POPA2991IDDFR is optimized for industrial process-control systems, 4-20 mA current loop receivers, and programmable logic controller analog input modules that require operation up to 40 V supplies. Its 130 dB CMRR and 4.5 MHz bandwidth make it a strong choice for precision difference amplifiers, instrumentation stages, and motor drive current-sensing circuits. The dual-channel configuration in an 8-pin SOT-23 package reduces BOM complexity in space-constrained field transmitters and sensor signal conditioners.

Frequently Asked Questions
What supply voltage and bandwidth does the POPA2991IDDFR support for industrial signal conditioning?
The POPA2991IDDFR operates from supplies up to 40 V and provides a gain-bandwidth product of 4.5 MHz per channel, making it suitable for wide-bandwidth differential signal conditioning in industrial 24 V and 36 V systems with good phase margin across audio and control frequencies.
How does the POPA2991IDDFR's CMRR specification compare to standard op amps for rejection of common-mode noise?
With a typical CMRR of 130 dB and a minimum of 109 dB, the POPA2991IDDFR rejects common-mode noise significantly better than general-purpose op amps rated at 70-80 dB, enabling accurate differential measurements even in electrically noisy industrial environments with 50 Hz or 60 Hz interference.
Can the POPA2991IDDFR replace discrete solutions in a 4-20 mA current loop receiver front-end?
Yes; its 40 V tolerance, 750 µV maximum offset, and rail-to-rail output allow direct use as a differential receiver or I-to-V converter in 4-20 mA loop powered transmitters, replacing multi-chip discrete circuits and saving approximately 50 % board space in the 8-pin SOT-23 package.
