Product details
Overview
TL084HIDYYR 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 feedback loops, motor drive current sensing, and pro-audio preamplifier stages.
For engineers reviewing the TL084HIDYYR datasheet, TL084HIDYYR pinout, TL084HIDYYR application, or TL084HIDYYR equivalent, this page provides verified electrical specifications, SOT-23-14 package details, functional pin mapping, real-world use cases in UPS and battery test equipment, and two validated alternative parts with documented technical and application differences.
Technical Context
The TL084HIDYYR implements a high-slew-rate JFET-input differential pair with integrated EMI/RF filters and 1.5 kV HBM ESD protection. Its architecture supports wide common-mode input (including VCC+) and maintains low input bias current (±1 pA typ) across –40°C to +125°C.
It achieves 5.25 MHz gain-bandwidth product and 56° phase margin with 20 pF capacitive load, enabling stable unity-gain configurations. Output short-circuit protection and 0.00012% THD+N at 1 kHz support high-fidelity signal paths in audio and measurement systems.

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 (500 V HBM), rated only to +70°C ambient | Not qualified for industrial temperature range; unsuitable for solar or UPS deployments above 70°C | Select TL084HIDYYR when operating beyond 70°C or requiring <1 mV offset stability |
| OPA4134UA | Lower noise (8 nV/√Hz), higher GBW (4 MHz), but higher IQ (2 mA/ch); no integrated EMI filter | Superior audio performance but lacks ESD/EMI hardening for motor drive or inverter EMI environments | Choose TL084HIDYYR for ruggedized industrial signal chains where EMI immunity and temperature range outweigh ultra-low-noise needs |
Compared with TL084CDR and OPA4134UA, TL084HIDYYR uniquely combines industrial temperature range (–40°C to +125°C), integrated EMI filtering, and 1.5 kV HBM ESD protection - making it the preferred choice for solar, UPS, and motor drive applications exposed to electrical stress and thermal extremes.

FAQ
What is the maximum supply voltage for TL084HIDYYR?
The TL084HIDYYR 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 long-term reliability and specified performance across –40°C to +125°C.
Does TL084HIDYYR include EMI filtering?
Yes, TL084HIDYYR integrates on-die EMI and RF filters, providing 53 dB EMI rejection ratio at 1 GHz. This eliminates the need for external RC filters in noisy environments such as motor drives and inverters, reducing BOM count and PCB area while maintaining signal integrity.
Can TL084HIDYYR operate with input voltages beyond the supply rails?
No - the absolute maximum input voltage is limited to (VCC–) – 0.5 V and (VCC+) + 0.5 V. However, its common-mode input range extends *to* VCC+, allowing inputs at the positive rail - a key advantage for high-side current sensing without level-shifting circuitry.
What is the thermal resistance (RθJA) of TL084HIDYYR in its DYY package?
The TL084HIDYYR in the 14-pin SOT-23 (DYY) package has a junction-to-ambient thermal resistance (RθJA) of 153.2°C/W, as specified in TI's thermal metrics documentation. This value assumes standard JEDEC 2-layer board conditions and guides heatsinking requirements for sustained full-load operation at elevated ambient temperatures.
Is TL084HIDYYR pin-compatible with older TL084 variants?
Yes - TL084HIDYYR uses the same 14-pin SOT-23 (DYY) footprint and pinout as TL084CDYYR and TL084ACDYYR. All share identical pin functions (e.g., Pin 1 = 1IN–, Pin 4 = VCC+, Pin 8 = VCC–), enabling drop-in replacement in existing designs while upgrading ESD, EMI, and temperature performance.
