Key Features
- Ultra-low JFET input bias current of 0.05 nA maximum at 25°C minimizes loading on high-impedance sensors and photodetectors
- 80 dB minimum common-mode rejection ratio with 90 dB typical ensures high noise immunity in differential measurement circuits
- Dual op amp configuration in a compact 10-lead LFCSP (CP-10-10) package reduces channel count BOM and saves board space
Applications
The ADA4062-2ACPZ-RL is suited for high-impedance sensor interfaces such as photodiode transimpedance amplifiers, pH electrode buffers, and capacitive sensor conditioning where ultra-low input bias current below 0.05 nA is required. It also performs well in precision instrumentation amplifier input stages and active filter designs that demand low noise and 80 dB or better CMRR. The dual configuration supports differential or stereo signal chains in portable medical and industrial measurement equipment.

Frequently Asked Questions
How does the ADA4062-2ACPZ-RL's input bias current specification benefit photodiode transimpedance amplifier designs?
The ADA4062-2ACPZ-RL specifies a maximum bias current of 0.05 nA at 25°C, which is more than 100 times lower than standard bipolar op amps. In a transimpedance amplifier with a 100 MΩ feedback resistor, this bias current contributes less than 5 mV of output offset, preserving measurement accuracy for low-light photodiode applications in optical instruments and medical imaging.
What common-mode rejection does the ADA4062-2ACPZ-RL guarantee for differential measurement in noisy industrial environments?
The ADA4062-2ACPZ-RL guarantees a minimum CMRR of 80 dB, with a typical value of 90 dB. This rejects 50 Hz or 60 Hz power-line interference coupled as common-mode noise by a factor of at least 10,000:1, making the device effective in industrial sensor signal conditioning where ground loops and switching noise are present on both input lines.
For a dual-channel pH measurement instrument, why is the ADA4062-2ACPZ-RL preferable to two single op amps?
The ADA4062-2ACPZ-RL integrates 2 matched JFET op amps in a single 10-lead LFCSP package, halving the component count versus two separate devices and reducing board area by approximately 40%. Channel-to-channel matching also improves differential accuracy in dual-electrode pH or ion-selective electrode setups, and the single package lowers procurement and assembly cost per channel.
When should a designer select the ADA4062-2ACPZ-RL over a CMOS input op amp for a high-impedance sensor buffer?
The ADA4062-2ACPZ-RL is preferred when the application requires stable bias current over a wide temperature range rather than the absolute lowest room-temperature leakage. JFET inputs maintain input bias current below the average maximum of 0.005 µA across the full operating temperature range, whereas CMOS inputs can exhibit exponentially rising leakage at elevated temperatures above 85°C, making the JFET device more reliable in industrial environments.
