Texas Instruments TL082HIDDFR

Overview

TL082HIDDFR from Texas Instruments is a dual 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 TL082HIDDFR datasheet, TL082HIDDFR pinout, TL082HIDDFR application, or TL082HIDDFR equivalent, this page provides verified electrical specifications, package-validated pin functions, thermal performance data, real-world application context for rugged environments, and two confirmed alternative parts with documented functional trade-offs.

Technical Context

The TL082HIDDFR implements a high-slew-rate JFET-input differential pair with integrated EMI/RF filters and robust electrostatic protection (1.5 kV HBM). Its architecture supports wide common-mode input voltage range-including VCC+-enabling direct sensing in high-side configurations without level-shifting.

It operates across –40°C to +125°C with guaranteed 118 dB open-loop gain, 5.25 MHz gain-bandwidth product, and 0.48 μs settling time to 0.01% for 2 V step under 40 V supply. Output short-circuit protection and 300 pF capacitive load drive capability support reliable interfacing with ADC drivers and active filters.

FAQ

What is the maximum supply voltage for TL082HIDDFR?

The TL082HIDDFR supports a total supply voltage (VCC+ to VCC–) range of ±2.25 V to ±20 V, or 4.5 V to 40 V single-supply operation. Absolute maximum ratings specify 42 V for non-NS/PS packages, but recommended operating conditions cap at 40 V to ensure long-term reliability and specified performance across –40°C to +125°C.

Does TL082HIDDFR support rail-to-rail input?

TL082HIDDFR features a common-mode input voltage range that extends to VCC+, satisfying rail-to-rail input capability on the positive side. However, the lower bound is (VCC–) + 1.5 V-not true rail-to-rail on the negative rail. This enables high-side sensing without level shifting but requires ≥1.5 V headroom below VCC–.

What is the thermal resistance (RθJA) of TL082HIDDFR in its DDF package?

The TL082HIDDFR in the 8-pin SOT-23 (DDF) package has a junction-to-ambient thermal resistance (RθJA) of 181.5°C/W, as specified in TI's thermal metrics table for dual-channel devices. This value assumes standard JEDEC high-K board conditions and informs heatsinking requirements for continuous 26 mA short-circuit operation at elevated ambient temperatures.

Can TL082HIDDFR drive capacitive loads?

Yes, TL082HIDDFR is characterized to drive up to 300 pF capacitive loads while maintaining stability, as confirmed by small-signal overshoot vs. capacitive load curves and phase margin testing. For loads >200 pF, consider adding a series resistor (e.g., 10–50 Ω) between output and capacitance to isolate reactive feedback and preserve 56° phase margin.

Is TL082HIDDFR pin-compatible with older TL082 variants?

TL082HIDDFR uses the standard 8-pin SOT-23 (DDF) pinout defined for TL082x dual op-amps and is pin-compatible with TL082CDR, TL082IDR, and TL082CPW in the same DDF package. Pin functions (1OUT, 1IN–, 1IN+, VCC–, 2IN+, 2IN–, 2OUT, VCC+) match exactly-no PCB redesign is required when upgrading from legacy TL082 versions in DDF.
