What are the key features of POPA2990IPWR?

  • Rail-to-rail input and output on a 40 V supply enables full-swing signal processing across the entire supply range in industrial measurement circuits
  • 115 dB typical common-mode rejection ratio with 1750 µV maximum offset voltage ensures high accuracy in precision sensing and signal conditioning
  • 1 MHz gain-bandwidth product with current-feedback architecture and frequency compensation suits a wide range of active filter and amplifier applications

What is POPA2990IPWR used for?

The POPA2990IPWR is suited for industrial sensor signal conditioning, precision measurement front ends, and analog signal chain designs operating from high-voltage supplies up to 40 V. Its rail-to-rail input/output capability maximizes dynamic range in single-supply systems monitoring 4–20 mA current loops and bridge sensor outputs. The low bias current of 3.5 nA maximum makes it ideal for high-impedance sensor interfaces and sample-and-hold circuits.

Frequently Asked Questions

What is the gain-bandwidth product of the POPA2990IPWR and how does it affect filter design?

The POPA2990IPWR has a 1 MHz gain-bandwidth product, which is adequate for low-frequency signal conditioning, active anti-aliasing filters below 100 kHz, and instrumentation amplifier stages in industrial sensor systems operating at audio and low-frequency measurement bandwidths.

How does the 115 dB CMRR of the POPA2990IPWR benefit differential sensor measurements?

The POPA2990IPWR achieves 115 dB typical common-mode rejection ratio with a minimum of 100 dB, which effectively suppresses common-mode noise and ground potential differences by more than 5 orders of magnitude, enabling accurate differential voltage measurements from bridge sensors, RTDs, and 4–20 mA loops in noisy industrial environments.

What maximum supply voltage does the POPA2990IPWR support and what does that enable?

The POPA2990IPWR operates from supplies up to 40 V, allowing direct interfacing with industrial 24 V bus systems and 4–20 mA signal loops without a dedicated level-shifting stage, which reduces component count and simplifies power supply design in field transmitters and process control modules.

Why is the POPA2990IPWR a strong choice for high-impedance sensor interfaces?

The POPA2990IPWR features a maximum bias current of only 3.5 nA, minimizing loading error on high-impedance sources such as pH electrodes, piezoelectric sensors, and MEMS transducers, where even microamp-level input currents would cause significant voltage errors at the amplifier input.
