Frequently Asked Questions
How does POPA4990IDR's rail-to-rail input and output capability benefit high-voltage industrial sensing designs?
POPA4990IDR supports rail-to-rail input and output across a 40 V supply range, allowing the amplifier to accurately process signals near both supply rails. This maximizes the usable dynamic range in 24 V or 40 V industrial sensor conditioning circuits without losing accuracy at signal extremes.
What is the gain-bandwidth product of POPA4990IDR, and how does it constrain filter design at audio and low-frequency ranges?
POPA4990IDR has a 1 MHz gain-bandwidth product per channel. At a closed-loop gain of 10 V/V, the useful bandwidth is approximately 100 kHz, which suits low-frequency signal conditioning, active anti-aliasing filters below 50 kHz, and sensor amplification stages in industrial data acquisition systems.
What is the CMRR of POPA4990IDR, and does it support differential current sensing across a shunt resistor in a motor drive?
POPA4990IDR achieves a nominal CMRR of 115 dB, which is well-suited for rejecting common-mode voltage on shunt resistors in 24 V to 40 V motor drives. With 4 channels available in a single 14-pin SOIC, multiple phase currents can be sensed simultaneously on one device.
What is the lifecycle status of POPA4990IDR, and how does the YTEOL value affect procurement planning?
POPA4990IDR shows a YTEOL of 0, indicating end-of-life or near-end-of-life status. Procurement teams should verify current availability, identify a pin-compatible replacement from the OPA4990 family, and plan a re-qualification if this 14-pin SOIC quad op-amp is used in long-duration production programs.
