What are the key features of TLE2061ACPE4?
- 60 fA typical JFET input bias current enables accurate signal conditioning for ultra-high-impedance photodiode and electrochemical sensors
- 90 dB typical common-mode rejection ratio with 1.5 mV maximum input offset voltage delivers precision performance in single-supply instrumentation
- High output drive capability in an 8-pin DIP package simplifies prototyping and lab evaluation of precision micropower amplifier designs
What is TLE2061ACPE4 used for?
The TLE2061ACPE4 suits precision instrumentation, photodiode transimpedance amplifiers, and electrochemical sensor front ends where ultra-low input bias current and micropower supply consumption are simultaneously required. Its JFET input stage holds bias current to sub-picoamp levels, enabling accurate current-to-voltage conversion of picoamp-range sensor signals in gas detectors, potentiostat circuits, and optical receivers without degrading measurement accuracy. The 8-pin DIP package allows rapid prototyping on breadboards and evaluation boards during sensor front-end development before migrating to surface-mount production layouts.

Frequently Asked Questions
For a photodiode transimpedance amplifier measuring 10 pA signals, how does TLE2061ACPE4's 60 fA bias current affect accuracy?
With 60 fA (0.06 pA) typical input bias current, TLE2061ACPE4 contributes less than 0.6% current error to a 10 pA photodiode signal—well within 1% precision limits for optical power meters. A standard bipolar op-amp drawing 200 nA would swamp the 10 pA signal entirely. The 60 fA spec allows use of high-value feedback resistors up to 100 GΩ for transimpedance gains exceeding 100 V/nA without bias-current-induced output offset dominating the measurement.
In what low-power instrument design scenario is TLE2061ACPE4's combination of JFET input and micropower supply current uniquely valuable?
Battery-operated gas detectors using electrochemical cells present source impedances of 100 MΩ or higher and require sub-nA signal currents to be amplified over months of continuous operation. TLE2061ACPE4's combination of 60 fA bias current and sub-milliwatt supply power allows an entire measurement front end to run from a 9 V alkaline battery for over 1000 hours while maintaining measurement accuracy better than 1%. This dual requirement rules out standard CMOS rail-to-rail op-amps that trade bias current for rail-to-rail output swing.
How does TLE2061ACPE4's 90 dB CMRR support precision differential measurements in a noisy industrial environment?
A 90 dB CMRR means a 1 V common-mode noise signal—such as 50 Hz or 60 Hz mains interference—produces only 31.6 µV of differential output error. In a 4–20 mA loop transmitter or thermocouple amplifier where the useful signal spans a few millivolts, this rejection level allows accurate readings without additional shielding or differential filters. The 65 dB minimum specification over process variation still provides over 1.8 mV worst-case rejection from a 1 V interference, keeping system error below 0.1% in millivolt-range measurements.
