Product details
Overview
TL084HIPWR from Texas Instruments is a quad JFET-input operational amplifier designed for precision analog signal conditioning in high-reliability industrial and power electronics systems. It delivers 20 V/μs slew rate, 1 mV typical input offset voltage, ±2.25 V to ±20 V dual-supply operation, low 940 μA/channel quiescent current, and rail-to-rail common-mode input range extending to VCC+. It is used in motor drive feedback loops, UPS voltage regulation, and pro-audio signal paths where low distortion (0.003% THD+N) and EMI robustness are critical.
For engineers reviewing the TL084HIPWR datasheet, TL084HIPWR pinout, TL084HIPWR application, or TL084HIPWR equivalent, this page provides verified electrical specifications, package-confirmed pin functions, real-world application context for solar inverters and AC drives, and validated alternative options for design continuity and supply resilience.
Technical Context
The TL084HIPWR implements a high-slew, low-noise JFET-input front-end with integrated EMI/RF filtering and 1.5 kV HBM ESD protection. Its input stage supports common-mode voltages up to VCC+, enabling direct sensing of signals referenced to positive rails - essential in high-side current monitoring and DC-link voltage scaling circuits.
It features output short-circuit protection, 5.25 MHz gain-bandwidth product, and stable operation with capacitive loads up to 300 pF. The device operates across –40°C to +125°C and maintains <±2 μV/°C offset drift, making it suitable for uncooled industrial environments where thermal stability is non-negotiable.

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 | Wider offset voltage (±3 mV max), lower ESD rating (1 kV HBM), –40°C to +85°C temp range | Not qualified for extended-temperature industrial or automotive environments requiring >85°C operation | Select when cost sensitivity outweighs thermal stability and EMI robustness requirements |
| OPA4134UA | Lower noise (8 nV/√Hz), higher GBW (4 MHz), ±18 V max supply, no integrated EMI filter | Lacks built-in RF suppression; requires external filtering in high-noise power electronics applications | Choose for ultra-low-noise audio or precision measurement where EMI environment is controlled |
Compared with TL084CDR and OPA4134UA, the TL084HIPWR uniquely combines extended temperature operation, integrated EMI hardening, and rail-to-rail common-mode input - making it the only option among the three qualified for uncooled solar inverter and industrial UPS designs without layout-level mitigation.

FAQ
What is the maximum supply voltage for TL084HIPWR?
The TL084HIPWR supports a total supply voltage (VCC+ to VCC–) of up to 40 V, or ±20 V in dual-supply configuration. Absolute maximum ratings specify 42 V for non-NS/PS packages, but recommended operating conditions limit continuous use to 40 V to ensure reliability across –40°C to +125°C ambient temperatures. Exceeding 40 V may degrade long-term parametric stability.
Does TL084HIPWR support rail-to-rail output swing?
No, TL084HIPWR does not provide rail-to-rail output swing. Its output voltage swing is limited to within 115–210 mV of each rail under 10 kΩ load at ±20 V supply. For example, with ±15 V supplies, output typically swings from –14.8 V to +14.8 V. This headroom is sufficient for most industrial signal conditioning but requires design margining in applications demanding full-rail utilization.
Is TL084HIPWR pin-compatible with standard TL084 variants?
Yes, TL084HIPWR uses the same 14-pin SOIC (D package) footprint and identical pinout as TL084CDR, TL084ACDR, and TL084BCDR. All four amplifier channels, supply pins, and terminal assignments match exactly - enabling drop-in replacement in existing designs without PCB modification, provided thermal and supply constraints are verified.
What is the input bias current specification for TL084HIPWR at 125°C?
At TA = +125°C, the input bias current for TL084HIPWR is specified at ±5 nA maximum (per amplifier). This is significantly higher than the ±1 pA typical value at 25°C but remains orders of magnitude lower than bipolar-input op-amps, preserving high-impedance interface integrity in elevated-temperature industrial deployments such as motor drive control boards.
Can TL084HIPWR drive a 1000 pF capacitive load?
No, TL084HIPWR is characterized for stable operation up to 300 pF capacitive load. Driving 1000 pF risks peaking, overshoot, or oscillation due to phase margin degradation. For heavier loads, external isolation resistors (e.g., 10–50 Ω in series with output) or unity-gain buffers with higher capacitive drive capability should be used. The datasheet confirms stability only up to 300 pF with 2 kΩ load.
