What are the key features of TL084IDE4?
- Quad JFET-input op-amp with ultra-low bias current of 0.02 µA max for high-impedance signal sources
- 86 dB typical common-mode rejection ratio (CMRR) ensuring accurate differential signal amplification
- Wide supply voltage range compatible with ±5 V to ±15 V dual-supply or single-supply configurations
What is TL084IDE4 used for?
The TL084IDE4 is widely used in audio signal processing, active filter design, and precision instrumentation where high-impedance JFET inputs minimize loading on sensor outputs. Its four independent op-amp channels in a single package make it cost-effective for multi-channel data acquisition front-ends and medical signal conditioning boards. The low input bias current of 0.02 µA makes it suitable for photodiode transimpedance amplifiers and charge-sensitive detector circuits.

Frequently Asked Questions
How does the JFET input stage of TL084IDE4 benefit high-impedance sensor interfaces?
The JFET input stage limits bias current to just 0.02 µA maximum, which creates negligible loading on high-impedance sources such as piezoelectric sensors or pH electrodes, preserving signal accuracy across a typical supply range of ±15 V in instrumentation circuits.
What active filter topologies are practical with the TL084IDE4's four op-amp channels?
With 4 independent channels, a single TL084IDE4 can implement a 4th-order Sallen-Key low-pass filter with 75 dB minimum CMRR, or a state-variable filter covering notch and bandpass outputs simultaneously, reducing component count versus using discrete dual-channel devices on a PCB.
Is TL084IDE4 a drop-in replacement for TL074 or LM324 in legacy analog boards?
TL084IDE4 is pin-compatible with the TL074 family in the SOIC-14 footprint and shares the quad op-amp pinout. However, LM324 uses a different input structure with 0.04 µA bias current and a single 5 V rail, so board-level supply and offset specifications must be verified before substitution.
