What are the key features of TLE2084CNE4?
- Ultra-low 175-pA typical input bias current for high-impedance sensor signal conditioning
- JFET input stage provides high input impedance with sub-picoampere leakage current
- 89-dB nominal CMRR for excellent common-mode noise rejection in precision amplifier circuits
- Quad configuration provides 4 op-amp channels in a single 14-pin DIP package
- Internal frequency compensation and voltage-feedback architecture for stable high-speed operation
What is TLE2084CNE4 used for?
The TLE2084CNE4 is well-suited for precision instrumentation amplifiers, active filters, and sample-and-hold circuits where ultra-low input bias current from high-impedance sources such as photodiodes, piezoelectric sensors, and electrochemical electrodes is critical. Its quad package provides four matched op-amp channels useful for 4-channel signal conditioning chains, differential amplifier networks, and multi-stage filter banks in audio, medical, and industrial measurement equipment. The high CMRR of 89-dB makes it effective in rejecting power-line and environmental common-mode interference in sensitive measurement applications.

Frequently Asked Questions
What type of input stage does the TLE2084CNE4 use and why does it matter?
The TLE2084CNE4 uses a JFET (Junction Field-Effect Transistor) input stage, which provides extremely high input impedance and ultra-low input bias current — typically 175-pA at 25°C with a maximum of 5-nA average. This makes it ideal for amplifying signals from high-impedance sources such as photodiodes, pH electrodes, piezoelectric sensors, and other sensors where BJT-input op-amps would introduce unacceptable loading errors.
What is the CMRR of the TLE2084CNE4?
The TLE2084CNE4 has a nominal common-mode rejection ratio (CMRR) of 89-dB and a minimum of 79-dB. This high CMRR means the amplifier effectively suppresses common-mode signals such as 50/60-Hz power-line interference and ground noise that appear equally on both inputs, making it suitable for precision differential measurement applications in noisy industrial and laboratory environments.
How many op-amp channels does the TLE2084CNE4 provide?
The TLE2084CNE4 contains 4 independent operational amplifier channels (quad op-amp) in a single 14-pin DIP package. All four channels share the same JFET input architecture and internal frequency compensation, providing matched performance across channels. This is useful for building 4-channel instrumentation systems, stereo differential amplifiers, or cascaded filter stages without requiring multiple packages.
What package does the TLE2084CNE4 come in and is it RoHS compliant?
The TLE2084CNE4 is packaged in a 14-pin plastic DIP (Dual In-Line Package), which is easy to prototype on breadboards and through-hole PCBs. The /E4 suffix indicates it is RoHS-compliant and lead-free (Pb-free), meeting REACH and environmental requirements. The DIP package is particularly convenient for laboratory prototyping and education applications.
What are typical applications for the TLE2084CNE4?
Typical applications include precision transimpedance amplifiers for photodetector circuits, active low-pass and band-pass filters, instrumentation amplifier front ends, sample-and-hold circuits, pH meter signal conditioning, and audio preamplifiers. The quad package and JFET inputs make it especially useful in multichannel data acquisition systems where four low-leakage amplifier channels are needed from a single IC to minimize board space and component count.
