Frequently Asked Questions
What input offset voltage does the POPA2189IDGKR guarantee over temperature?
The POPA2189IDGKR specifies a maximum input offset voltage of 8 µV at room temperature, and the zero-drift (auto-zero) architecture maintains this accuracy across the full operating temperature range without the offset drift typically seen in conventional op-amps, which can exceed 1 µV/°C.
How does the 14 MHz gain-bandwidth product affect signal chain design at closed-loop gains above 100?
At a closed-loop gain of 100 V/V, the POPA2189IDGKR delivers approximately 140 kHz of usable bandwidth, making it suitable for precision amplification of low-frequency sensor signals up to 100 kHz while maintaining 120 dB CMRR and sub-10 µV offset.
For a 16-channel multiplexed data acquisition system, why is the POPA2189IDGKR's MUX-friendly feature important?
In a 16-channel multiplexed system where the input switches every 10 µs, the POPA2189IDGKR's fast overdrive recovery ensures the output settles to within 1 LSB of a 16-bit ADC before the next conversion, preventing inter-channel crosstalk and maintaining measurement accuracy across all 16 inputs.
What package does the POPA2189IDGKR use and how does it compare to a DIP alternative for PCB density?
The POPA2189IDGKR uses an MSOP-8 package with a footprint of approximately 3 mm × 3 mm, roughly 6× smaller than an 8-pin DIP package, enabling dual op-amp functionality in high-density multi-channel PCB layouts common in 19-inch rack-mounted industrial instruments.
