What are the key features of TL084X2DBLE?
- Octal JFET-input op-amp array with 400 pA typical bias current, enabling high-impedance sensor interfacing without loading errors
- 4 MHz gain-bandwidth product with 76 dB CMRR across a wide supply range from ±5 V to ±18 V
- 30-pin SO package integrating 8 independent amplifier channels, reducing PCB area and component count in multi-channel signal chains
What is TL084X2DBLE used for?
TL084X2DBLE is ideal for multi-channel active filter banks, sample-and-hold circuits, and analog signal conditioning boards where eight amplifier stages are needed in a single package. Its ultra-low 400 pA input bias current suits high-impedance sources such as pH electrodes, piezoelectric sensors, and photodiodes without introducing measurable loading errors. Industrial data-acquisition front ends, audio mixing matrices, and multichannel instrumentation amplifiers benefit from consolidating 8 op-amps into one 30-pin footprint.

Frequently Asked Questions
How does TL084X2DBLE's 400 pA typical input bias current benefit measurements from high-impedance sources like pH electrodes?
With only 400 pA typical input bias current, TL084X2DBLE introduces a voltage error of just 4 µV across a 10 MΩ electrode impedance, compared to 500 µV for a bipolar op-amp with 50 nA bias current at the same impedance. This 125x reduction in offset error makes pH probes, ion-selective electrodes, and MEMS pressure sensors readable with negligible drift.
What closed-loop bandwidth does TL084X2DBLE achieve at a gain of 100 V/V, and is it usable for audio-frequency active filter designs?
At a closed-loop gain of 100 V/V (40 dB), TL084X2DBLE delivers a usable bandwidth of approximately 40 kHz based on its 4 MHz gain-bandwidth product. This covers the full audio band from 20 Hz to 20 kHz with 2x headroom, making it adequate for active Butterworth or Sallen-Key filters in audio crossover and equalizer designs.
For a multi-channel analog front end requiring 8 op-amps, how does consolidating them into TL084X2DBLE reduce board complexity versus using two quad packages?
TL084X2DBLE integrates all 8 channels into a single 30-pin SO package, eliminating one IC, reducing power bypass capacitors from 4 to 2, and cutting total solder joints by approximately 30 compared to two TL084 quad packages. Board area savings approach 40 mm² on a dense PCB, and a single supply decoupling network simplifies layout and reduces EMI from multiple power pins.
