Texas Instruments TL082HIDR

Overview

TL082HIDR 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, ±2.25 V to ±20 V dual-supply operation, 5.25 MHz gain-bandwidth product, and rail-to-rail common-mode input range extending to VCC+. It is used in motor drive current sensing and UPS feedback control loops.

For engineers reviewing the TL082HIDR datasheet, TL082HIDR pinout, TL082HIDR application, or TL082HIDR equivalent, key selection criteria include input bias current (±1 pA typ), EMI rejection ratio (53 dB at 1 GHz), low THD+N (0.00012% typ), thermal performance in SOIC-8 (RθJA = 147.8°C/W), and guaranteed operation from –40°C to +125°C.

Technical Context

The TL082HIDR implements a dual-channel, high-slew-rate JFET-input architecture with integrated EMI/RF filters and 1.5-kV HBM ESD protection. Its input stage supports common-mode voltage up to VCC+, enabling direct sensing of high-side signals without level-shifting.

It features output short-circuit protection, 300 pF capacitive load drive capability, and stable unity-gain operation with 56° phase margin. The device maintains 118 dB open-loop gain and 95 dB CMRR across –40°C to +125°C, supporting robust closed-loop accuracy in demanding environments.

FAQ

What is the maximum supply voltage for TL082HIDR?

The TL082HIDR supports a total supply voltage (VCC+ to VCC–) of up to 40 V, corresponding to ±20 V dual supplies 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 limit continuous use to 40 V to ensure reliability and parametric compliance across temperature.

Does TL082HIDR have internal offset null capability?

No, TL082HIDR does not include offset null pins. Unlike older TL082 variants (e.g., TL082CP with pins 1 and 5 for offset adjustment), the TL082HIDR uses a trimmed architecture achieving ±1 mV typical input offset voltage without external nulling circuitry-simplifying PCB layout and reducing component count.

Can TL082HIDR drive capacitive loads reliably?

Yes, TL082HIDR is characterized to drive up to 300 pF capacitive loads while maintaining stability, with 56° phase margin at unity gain and 20 pF load. For heavier loads (>100 pF), TI recommends adding a small series resistor (10–50 Ω) between the output and capacitance to preserve phase margin and prevent peaking in TL082HIDR step responses.

How does TL082HIDR compare to TL082CP in terms of ESD protection?

TL082HIDR provides ±1.5 kV HBM ESD protection per JEDEC JS-001, significantly exceeding the ±0.75 kV typical rating of legacy TL082CP. This enhanced robustness reduces susceptibility to handling damage and improves yield in automated assembly lines and field-repair scenarios involving TL082HIDR.

Is TL082HIDR suitable for single-supply operation?

Yes, TL082HIDR supports true single-supply operation from 4.5 V to 40 V. Its input common-mode range extends to VCC+, allowing high-side sensing without level-shifting, and its output swings within 115 mV of each rail (at 10 kΩ load), making it viable for rail-to-rail input/single-supply signal chains when referenced appropriately.
