What are the key features of POPA4202IPWR?
- Ultra-low input offset voltage of 200 µV and 9 nV/√Hz voltage noise density for precision analog signal conditioning
- Super-beta input stage with 2 nA maximum bias current and 148 dB typical CMRR, minimizing errors in high-impedance sensor interfaces
- High 25 nF capacitive load drive capability with internal frequency compensation, enabling direct connection to long cables and large bypass capacitors
What is POPA4202IPWR used for?
The POPA4202IPWR is designed for precision instrumentation amplifiers, medical biosignal front-ends, and industrial sensor signal chains where ultra-low offset, minimal noise below 10 nV/√Hz, and high CMRR above 126 dB are critical. Its super-beta input and ability to drive 25 nF capacitive loads make it equally suitable for active filter stages, data acquisition front-ends, and precision DAC output buffers in high-accuracy measurement systems.

Frequently Asked Questions
How low is the input offset voltage of the POPA4202IPWR and why does it matter for precision measurements?
The POPA4202IPWR has a maximum input offset voltage of 200 µV, which directly limits the DC error in precision measurement circuits. For a gain-of-100 instrumentation stage, a 200 µV offset contributes only 20 mV at the output, keeping system-level accuracy within tight bounds without requiring manual trimming.
What capacitive load can the POPA4202IPWR drive directly and how does this benefit cable-connected sensor applications?
The POPA4202IPWR supports up to 25 nF capacitive drive with internal frequency compensation, allowing direct connection to long shielded cables, large decoupling capacitors, or sample-and-hold circuits. Most precision op-amps are limited to 100 pF to 1 nF, so the 25 nF rating dramatically reduces the need for external isolation resistors.
How does the POPA4202IPWR's CMRR specification benefit differential sensor measurements in noisy industrial environments?
With a minimum CMRR of 126 dB and a typical value of 148 dB, the POPA4202IPWR rejects common-mode interference more than 10 dB better than standard 120 dB precision op-amps. This translates to attenuating a 1 V common-mode noise signal down to less than 4 µV at the output, preserving measurement integrity in electrically noisy environments.
What is the bias current specification of the POPA4202IPWR and which high-impedance sensor interfaces benefit from it?
The POPA4202IPWR has a maximum input bias current of only 2 nA at 25°C, achieved through its super-beta transistor input stage. This is critical for pH electrodes, photodiodes, and piezoelectric sensors with source impedances exceeding 10 MΩ, where a 2 nA current produces less than 20 mV of error voltage across such high-impedance sources.
