Key Features
- Ultra-low JFET input bias current of 60pA typical at 25C minimizes loading errors in high-impedance sensor interface circuits
- 82dB typical common-mode rejection ratio (CMRR) ensures excellent rejection of common-mode noise in differential measurement applications
- High-output-drive micropower architecture balances low supply current consumption with the ability to drive heavier capacitive and resistive loads
- Voltage-feedback topology with internal frequency compensation simplifies stability analysis and reduces external component count in amplifier designs
Applications
The TLE2061AIPE4 is well-suited for precision instrumentation, photodiode transimpedance amplifiers, and pH electrode buffer stages where ultra-low input bias current is critical to measurement accuracy. Its micropower supply current makes it ideal for battery-operated portable test equipment, medical monitoring devices, and remote sensor nodes that require long battery life. The high output drive capability allows it to interface directly with ADC inputs or drive resistive loads without additional buffer stages.

Frequently Asked Questions
What makes the TLE2061AIPE4 a JFET-input op-amp and why does it matter?
The TLE2061AIPE4 uses JFET transistors at its inputs, which have inherently high input impedance and very low leakage current. This results in an extremely low bias current of 60pA typical at 25C, making it ideal for applications like photodiode amplifiers, charge amplifiers, and pH meter buffers where source impedance is very high and any input current would cause significant measurement error.
What is the common-mode rejection ratio (CMRR) of the TLE2061AIPE4?
The TLE2061AIPE4 has a typical CMRR of 82dB and a minimum of 65dB. A high CMRR means the amplifier rejects noise and interference that appears equally on both input terminals, which is essential in differential measurement systems such as bridge sensor amplifiers, ECG circuits, and industrial 4-20mA signal conditioning.
What does micropower mean for the TLE2061AIPE4?
Micropower refers to the TLE2061AIPE4's very low quiescent supply current consumption, allowing it to operate for extended periods from small batteries or energy-harvesting sources. This makes it suitable for portable, wearable, and remote sensor applications where minimizing power draw is as important as achieving good signal amplification performance.
What package and pin configuration does the TLE2061AIPE4 use?
The TLE2061AIPE4 is packaged in an 8-Pin PDIP (Plastic Dual In-Line Package), which is the standard through-hole format compatible with breadboards and DIP sockets for easy prototyping. The 'e4' suffix indicates a RoHS-compliant lead-free finish per JESD-609 Code e4.
What are common applications for the TLE2061AIPE4?
Common applications include transimpedance amplifiers for photodetectors and photodiodes, pH and ion-selective electrode signal buffers, precision integrators, sample-and-hold circuits, and portable instrumentation front-ends. The combination of low bias current, good CMRR, and micropower operation addresses a broad range of precision analog sensing tasks where accuracy and battery life must be balanced.
