What are the key features of POPA2388IDR?
- Zero-drift and zero-crossover architecture delivering 134 dB typical CMRR and sub-nanoamp bias current of 0.7 nA for the highest DC accuracy in precision sensor conditioning
- 10 MHz gain-bandwidth product with true rail-to-rail input and output enabling fast, full-swing signal processing on 3.3 V or 5 V single-supply systems
- Dual amplifier in one 8-pin SOIC package reducing board area by 50% compared to two single-channel op-amps while sharing a common supply for compact differential signal chain designs
What is POPA2388IDR used for?
The POPA2388IDR is ideal for high-precision weigh scales and pressure sensor interfaces, where its zero-drift architecture and 134 dB CMRR suppress noise and offset drift over temperature without trimming. It is used in medical diagnostics equipment such as blood-pressure monitors and ECG front-ends requiring sub-microvolt input offset performance at very low bias currents of 0.7 nA. Its 10 MHz bandwidth also supports precision active filter designs in test and measurement instruments where both DC accuracy and AC response matter.

Frequently Asked Questions
What CMRR performance does POPA2388IDR offer and why does it matter for a differential sensor interface?
The POPA2388IDR achieves 114 dB minimum and 134 dB typical CMRR, meaning common-mode noise—such as 50/60 Hz power-line interference on long sensor cables—is rejected by a factor of over 1 million, keeping measurement errors well below 1 µV even in electrically noisy industrial environments.
How does the zero-drift architecture of POPA2388IDR benefit a precision weigh-scale design over temperature?
Zero-drift continuously corrects input offset voltage so the POPA2388IDR maintains offset well below 10 µV even as temperature varies from -40°C to 125°C, eliminating periodic system recalibration that standard op-amps require every few degrees and providing stable milligram-level weighing accuracy.
What bias current does POPA2388IDR draw from high-impedance sensors and what does that enable?
With a bias current max of 0.0007 µA (700 pA), the POPA2388IDR can interface directly to high-impedance sources such as 1 MΩ electrochemical or pH sensors without introducing significant voltage error from the bias current-resistance product, maintaining sub-microvolt accuracy at the amplifier input.
For a 5 V single-supply precision ADC driver, how does POPA2388IDR's 10 MHz bandwidth compare to typical zero-drift op-amps?
Most zero-drift op-amps offer only 0.5 MHz to 2 MHz bandwidth due to their chopper-stabilization circuitry; the POPA2388IDR's 10 MHz gain-bandwidth product is 5–20 times wider, enabling it to drive fast 16-bit SAR ADCs sampling at several hundred kilohertz without introducing excessive settling-time errors.
