Product details
Overview
TL084HIDR from Texas Instruments is a quad JFET-input operational amplifier optimized for precision, high-speed analog signal conditioning in industrial and power electronics. It delivers 20 V/μs slew rate, 1 mV typical input offset voltage, 37 nV/√Hz input voltage noise at 1 kHz, ±2.25 V to ±20 V dual-supply operation, and rail-to-rail common-mode input range extending to VCC+. It is used in solar inverter voltage sensing, motor drive current feedback, and pro-audio preamplifier stages.
For engineers reviewing the TL084HIDR datasheet, TL084HIDR pinout, TL084HIDR application, or TL084HIDR equivalent, this page provides verified specifications, SOIC-14 package layout, real-world use cases in UPS and battery test equipment, and validated alternative options with documented functional and thermal differences.
Technical Context
The TL084HIDR integrates four independent JFET-input op-amps sharing a single SOIC-14 package, each featuring high-impedance (>1 TΩ) differential and common-mode input resistance, integrated EMI/RF filters, and output short-circuit protection. Its architecture supports stable unity-gain operation with 5.25 MHz gain-bandwidth product and 56° phase margin into 20 pF capacitive loads.
Designed for rugged environments, it operates across –40°C to +125°C with 1.5 kV HBM ESD rating and maintains low offset drift (±2 μV/°C) and low quiescent current (937.5–1125 μA per amplifier), enabling reliable performance in unregulated or thermally variable systems like string inverters and servo drive modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL084CDR | Higher max offset (±3 mV), wider temp range (0°C to 70°C only), no integrated EMI filter | Limited to commercial-grade systems; unsuitable for industrial UPS or solar where EMI immunity is required | Select TL084CDR only for cost-sensitive, low-noise, non-ruggedized designs with benign EMC environments |
| OPA4134UA | Lower noise (8 nV/√Hz), higher GBW (4 MHz), rail-to-rail output, but no VCC+-inclusive CM range | Better for audio, worse for high-side sensing; lacks short-circuit protection and ESD robustness (1 kV HBM) | Choose OPA4134UA when ultra-low noise dominates over input range and ruggedness-e.g., studio microphone preamps |
Compared with TL084CDR and OPA4134UA, TL084HIDR uniquely combines VCC+-inclusive common-mode input, integrated EMI filtering, and 1.5 kV HBM rating-making it the only option among the three qualified for harsh industrial power electronics environments.

FAQ
What is the maximum operating temperature for TL084HIDR?
The TL084HIDR is rated for continuous operation from –40°C to +125°C ambient temperature. This extended range is validated by TI's characterization data and enables use in sealed motor drive enclosures and outdoor solar inverters without derating. The SOIC-14 package's RθJA of 114.2°C/W ensures thermal compliance under typical PCB copper pour conditions. TL084HIDR maintains specified offset drift (±2 μV/°C) and gain accuracy across this full range.
Does TL084HIDR support single-supply operation?
Yes, TL084HIDR supports true single-supply operation from 4.5 V to 40 V. Its common-mode input range extends from (VCC–) + 1.5 V to VCC+, allowing input signals referenced to ground or mid-rail without level-shifting. For example, with VCC– = 0 V and VCC+ = 12 V, valid input range is 1.5 V to 12 V. Output swing remains within 115–210 mV of each rail under 10 kΩ load, preserving dynamic range in 3.3 V or 5 V microcontroller-based systems.
How does TL084HIDR differ from legacy TL084 variants?
TL084HIDR is the high-reliability "H" variant of the TL084 family, featuring lower typical offset voltage (1 mV vs. 3–10 mV), improved ESD rating (1.5 kV HBM vs. 1 kV), integrated EMI/RF filters, and guaranteed operation to +125°C. Unlike TL084CDR or TL084IDR, TL084HIDR includes production-tested parameters for industrial environments-including enhanced PSRR (±1 μV/V) and tighter offset drift (±2 μV/°C). These improvements are documented in TI's SLOS081O revision September 2025 datasheet.
Can TL084HIDR drive capacitive loads reliably?
TL084HIDR is characterized for stable operation with up to 300 pF capacitive load, supported by 56° phase margin at unity gain with 20 pF load. Its internal compensation and low open-loop output impedance (125 Ω at 1 MHz) prevent peaking or oscillation in typical sensor interface and filter applications. For loads >200 pF, TI recommends adding a small series resistor (10–50 Ω) between output and capacitance to isolate reactive feedback-verified in Figure 5-25 of the TL084HIDR datasheet.
Is TL084HIDR pin-compatible with other TL084 packages?
Yes, TL084HIDR in SOIC-14 (D) package is pin-compatible with all TL084x variants in the same D package-including TL084CDR, TL084IDR, and TL084ACDR. Pin functions match Table 4-5 exactly: Pins 1/7/8/11/14 are outputs, Pins 2/3/5/6/9/10/12/13 are inputs, and Pins 4/8 are VCC+/VCC–. No PCB redesign is needed when upgrading from legacy TL084D variants to TL084HIDR, provided thermal and EMI design margins are reviewed.
