What are the key features of TL084HIDYYR?
- Quad JFET input stage delivers 0.00012 µA maximum bias current, enabling high-impedance sensor interfaces with negligible loading error
- ±20 V dual-supply or 40 V single-supply operation provides versatility across instrumentation, audio, and industrial analog circuit designs
- 100 dB minimum CMRR with voltage-feedback architecture ensures high noise rejection in differential signal conditioning and precision amplifier stages
What is TL084HIDYYR used for?
TL084HIDYYR is used in precision instrumentation amplifiers, active filter banks, and audio processing circuits where four independent op-amp channels with JFET inputs are required. Its ±20 V supply range and 100 dB CMRR make it suitable for industrial analog front-ends, data-acquisition input stages, and scientific measurement equipment demanding low input leakage. The compact 14-pin TSOT-23 package supports space-constrained industrial and automotive-adjacent analog boards.

Frequently Asked Questions
Why choose TL084HIDYYR over a bipolar quad op-amp for a high-impedance pH or ion-selective electrode interface?
TL084HIDYYR uses a JFET input stage that limits bias current to just 0.00012 µA maximum, compared to bipolar op-amps with bias currents of 50–500 nA. For a pH electrode with 100 MΩ source impedance, the 0.00012 µA JFET bias causes only 12 µV of offset error versus 5–50 mV for bipolar devices, preserving measurement accuracy.
What supply voltage range does TL084HIDYYR accept, and how does it fit dual-supply instrumentation racks?
TL084HIDYYR accepts ±20 V dual supplies (40 V total) or a 40 V single supply, covering the standard ±15 V rails common in bench instrumentation and benchtop test equipment. This wide range means the same device serves both ±5 V portable systems and high-headroom ±15 V to ±18 V laboratory instrument channels without changing components.
How does the 100 dB CMRR of TL084HIDYYR benefit differential signal measurement in noisy industrial environments?
At 100 dB minimum CMRR, TL084HIDYYR attenuates common-mode interference—such as 50 Hz or 60 Hz mains noise on differential sensor wiring—by a factor of 100,000:1. In a 4–20 mA industrial loop running at ±15 V, this suppresses 1 V of common-mode noise to just 10 µV at the output, maintaining measurement resolution well below the LSB of a 16-bit ADC.
What is the package format of TL084HIDYYR and how does it compare to the traditional 14-pin SOIC TL084 in board layout?
TL084HIDYYR uses a 14-pin TSOT-23 package, which has a footprint of approximately 3.0 mm × 4.9 mm versus the larger 14-pin SOIC at 8.7 mm × 3.9 mm. The TSOT-23 reduces occupied board area by more than 40%, enabling higher-density analog circuit integration while maintaining the same quad-channel electrical performance.
