What are the key features of POPA990IDCKR?

  • 40V rail-to-rail input and output range enabling full-swing signal processing in high-voltage single-supply systems
  • 115 dB nominal CMRR with 100 dB minimum for superior common-mode noise rejection in precision signal chains
  • 1 MHz gain-bandwidth product in a compact SOT-23-5 (5-pin) surface-mount package
  • 1750 µV maximum input offset voltage for accurate low-level measurements without trimming

What is POPA990IDCKR used for?

The POPA990IDCKR is suited for precision signal conditioning in high-voltage sensor interfaces, industrial measurement systems, and battery-monitoring circuits operating from single supplies up to 40V. Its rail-to-rail input and output capability maximizes dynamic range even at low supply voltages, making it valuable for 4-20 mA current-loop transmitters and analog front-ends in portable instruments. The SOT-23-5 package enables dense PCB integration in space-constrained designs such as handheld test equipment, industrial field transmitters, and power management signal chains.

Frequently Asked Questions

What is the maximum supply voltage and input/output swing of POPA990IDCKR?

The POPA990IDCKR supports a maximum supply voltage of 40V and provides rail-to-rail input and output, meaning the common-mode input range extends to both supply rails and the output can swing within millivolts of both rails. This enables full dynamic range usage in single-supply 40V systems such as industrial sensor transmitters and motor current sensing circuits without signal clipping at the top or bottom of the supply range.

How does POPA990IDCKR's 115 dB nominal CMRR compare to general-purpose op amps and why does it matter?

The POPA990IDCKR achieves 115 dB nominal CMRR (100 dB minimum), which is significantly higher than general-purpose op amps that typically offer 70–80 dB. In differential measurement applications such as current sensing, bridge amplification, or 4-20 mA loop receivers, higher CMRR means ground noise, EMI, and power supply variations are rejected more aggressively, preserving measurement accuracy without additional filtering components in 40V industrial environments.

What gain-bandwidth product does POPA990IDCKR provide and is it adequate for audio or mid-frequency signal processing?

POPA990IDCKR provides a 1 MHz gain-bandwidth product, which is sufficient for DC to audio-frequency signal conditioning, active low-pass filters up to several hundred kilohertz at unity gain, and moderate closed-loop gain stages in sensor amplifier chains. For higher-frequency applications requiring bandwidths above 1 MHz at meaningful gain, a wider GBW op amp would be needed, but for industrial sensor signal chains and audio conditioning at gains of 10 or below, 1 MHz GBW is practical.

How compact is the SOT-23-5 package of POPA990IDCKR and what assembly style does it support?

The SOT-23-5 package (JESD-30 R-PDSO-G5) is a 5-pin surface-mount package measuring approximately 3 mm × 1.75 mm, one of the smallest standard op amp packages available. This compact footprint enables dense PCB integration in handheld instruments, wearable devices, and IoT sensor nodes where minimizing board area is critical, while still maintaining 40V capability and the 115 dB CMRR performance of the POPA990IDCKR.
