Texas Instruments TL082ID

Overview

TL082ID from Texas Instruments is a dual JFET-input operational amplifier designed for precision analog signal conditioning in industrial and audio systems. It delivers 20 V/μs slew rate, ±1 mV input offset voltage (typ), 5.25 MHz gain-bandwidth product, and operates from ±2.25 V to ±20 V supplies. Its rail-to-rail common-mode input range including VCC+ enables use in high-side sensing and active filter stages.

For engineers reviewing the TL082ID datasheet, TL082ID pinout, TL082ID application, or TL082ID equivalent, this page provides verified specifications, SOIC-8 package layout, dual-channel FET-input performance context, and validated alternatives for cost-sensitive, low-noise, wide-supply op-amp selection.

Technical Context

The TL082ID uses JFET-input differential pairs with high-impedance inputs (input bias current ≤120 pA typ) and internal frequency compensation for unity-gain stability. Its architecture supports wide common-mode input range extending to VCC+, enabling direct interfacing with sensors operating near supply rails.

It features low 37 nV/√Hz input voltage noise at 1 kHz and 0.00012% THD+N, making it suitable for pro-audio preamplifiers and precision instrumentation front-ends where signal integrity and DC accuracy are critical under varying temperature and supply conditions.

FAQ

What is the maximum supply voltage for TL082ID?

The TL082ID supports a total supply voltage range of 4.5 V to 40 V (±2.25 V to ±20 V). Absolute maximum ratings specify 42 V for continuous operation, but recommended operating conditions cap at 40 V to ensure long-term reliability and specified performance across temperature. Exceeding 40 V may degrade PSRR and increase offset drift beyond datasheet limits.

Does TL082ID have rail-to-rail input or output capability?

The TL082ID features rail-to-rail common-mode input range-including VCC+-but does not provide rail-to-rail output swing. Its output typically swings within 105–215 mV of each rail under 10 kΩ load. For true rail-to-rail output, consider modern alternatives like TLV2462; TL082ID remains optimal where input range inclusivity matters more than output headroom.

Can TL082ID drive capacitive loads directly?

Yes, TL082ID is characterized to safely drive up to 300 pF capacitive load without oscillation, thanks to internal compensation and phase margin optimization (56° at G = +1). For loads >300 pF, external isolation resistance (e.g., 10–100 Ω in series with output) is recommended to maintain stability in high-frequency feedback networks.

Is TL082ID pin-compatible with other TL082 variants?

Yes, TL082ID shares identical SOIC-8 pinout with TL082CDR, TL082CP, and TL082ACDR. All adhere to the standard dual-op-amp pin mapping (Pins 1/7 = outputs, 2/3/5/6 = inputs, 4/8 = supplies). However, electrical specs differ-TL082ID offers superior offset, drift, and EMI rejection versus commercial-grade versions.

What is the typical input bias current of TL082ID at 25°C?

The typical input bias current of TL082ID is ±1 pA at 25°C, with a maximum of ±120 pA across the full –40°C to +125°C range. This ultra-low value stems from its JFET-input architecture and makes TL082ID ideal for high-impedance sensor interfaces such as piezoelectric transducers or pH electrodes where leakage current would otherwise dominate error budgets.
