Product details

Overview

TL082AIYDT from STMicroelectronics is a high-speed JFET-input dual operational amplifier in SO8 package, rated for automotive temperature range (−40 °C to +105 °C), featuring 16 V/µs typical slew rate, ±11 V input common-mode range, and 2.5 MHz gain-bandwidth product. It delivers low input bias current (20 pA typ.), low offset voltage drift (10 µV/°C), and output short-circuit protection - used in precision sensor signal conditioning and automotive analog front-ends.

For engineers reviewing the TL082AIYDT datasheet, TL082AIYDT pinout, TL082AIYDT application, or TL082AIYDT equivalent, key selection criteria include its AEC-Q100 qualified automotive grade, JFET-input impedance (>10¹² Ω), differential input voltage tolerance (±30 V), and thermal resistance (125 °C/W junction-to-ambient in SO8).

Technical Context

The TL082AIYDT integrates two matched high-voltage JFET-input stages with bipolar output stages on a single monolithic die, enabling rail-to-rail compatible input operation up to V_CC+ and high common-mode rejection (80–86 dB). Its internal frequency compensation ensures unity-gain stability without external components.

Designed for robustness in harsh environments, it supports infinite output short-circuit duration under thermal limits, exhibits latch-up free operation, and meets AEC-Q100 Grade 1 stress testing including HBM ESD (1 kV) and CDM (1500 V), with specified operating supply range of 6–36 V.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	6 V to 36 V - supports wide industrial and automotive battery-supplied systems without external regulators
Slew Rate	16 V/µs (typ.) - enables faithful reproduction of fast-changing signals up to ~1 MHz at unity gain
Gain-Bandwidth Product	2.5 MHz (min) - sets usable closed-loop bandwidth for gain-of-10 configurations at ~250 kHz
Input Offset Voltage	3 mV (max at 25 °C), 6 mV (max over full temp range) - defines DC accuracy in precision amplification paths
Input Bias Current	20 pA (typ. at 25 °C) - minimizes voltage error across high-impedance source networks (e.g., piezoelectric sensors)
Common-Mode Range	±11 V (min) - allows direct interfacing with signals referenced near supply rails in single-supply configurations
Output Short-Circuit Current	10–60 mA - provides fault-tolerant drive capability while limiting thermal runaway risk

Pinout & Package

TL082AIYDT is housed in an 8-pin SO8 (Small Outline) package per JEDEC MS-012, with 1.27 mm pitch, gull-wing leads, and 125 °C/W thermal resistance junction-to-ambient.

Pin/Terminal	Circuit Role	Design Meaning
Inverting Input (Pin 2)	First op-amp inverting input	Accepts feedback network connection for stable closed-loop gain configuration
Non-inverting Input (Pin 3)	First op-amp non-inverting input	Receives reference or sensor signal with minimal loading due to >10¹² Ω input impedance
Output (Pin 1)	First op-amp output	Drives loads up to 2 kΩ with ±10 V swing; short-circuit protected indefinitely within thermal limits
V_CC− (Pin 4)	Negative supply rail	Reference for dual-supply operation; supports split-rail (±15 V) or asymmetric supplies (e.g., +12 V / −5 V)
Non-inverting Input (Pin 5)	Second op-amp non-inverting input	Enables independent signal path for differential pair, active filter sections, or dual-channel sensing
Inverting Input (Pin 6)	Second op-amp inverting input	Supports cascaded gain stages or summing configurations without cross-talk (120 dB channel separation)
Output (Pin 7)	Second op-amp output	Provides identical AC/DC performance as Pin 1; shares same supply pins for compact layout
V_CC+ (Pin 8)	Positive supply rail	Completes dual-supply path; decoupling capacitor placement critical for high-frequency stability

Key Features

Feature	Design Value
High Input Impedance	JFET input stage delivers >10¹² Ω resistance - preserves signal integrity from high-Z sources like pH electrodes or photodiodes
Wide Common-Mode Range	Extends to V_CC+ - enables direct interface with signals near positive rail without level-shifting circuitry
Internal Frequency Compensation	Unity-gain stable without external components - reduces BOM count and layout sensitivity in standard gain configurations
Output Short-Circuit Protection	Rated for indefinite short-circuit to either rail - eliminates need for external current-limiting resistors in fault-prone interfaces
AEC-Q100 Qualified	Automotive Grade 1 (−40 °C to +105 °C) - validated for engine control, body electronics, and ADAS sensor signal chains

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual JFET op-amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TL082CDT	Commercial-grade (0 °C to +70 °C), same SO8 package and electrical specs except wider offset voltage (3–10 mV vs. 3–6 mV)	Not qualified for automotive or extended-temperature industrial use; lacks AEC-Q100 screening	Select when cost-sensitive consumer or lab equipment requires identical functionality without automotive reliability requirements
OPA2134UA	Faster slew rate (20 V/µs), lower noise (8 nV/√Hz), but higher supply current (4 mA vs. 1.4–2.5 mA); SO8 package	Better audio fidelity and precision measurement, but reduced battery life in portable designs	Prefer for high-fidelity audio or metrology where noise and speed outweigh power constraints

Compared with TL082CDT, TL082AIYDT adds automotive qualification and tighter offset drift; versus OPA2134UA, it trades lower noise and speed for lower quiescent current and broader supply tolerance - making it optimal for cost-constrained, thermally demanding dual-op-amp roles.

FAQ

Is TL082AIYDT pin-compatible with TL082CDT?

Yes - both share identical SO8 footprint, pin assignment, and electrical pin functions. The only differences are temperature rating (−40 °C to +105 °C vs. 0 °C to +70 °C) and AEC-Q100 qualification. No PCB redesign is needed when upgrading from commercial to automotive grade.

What is the maximum safe continuous output short-circuit current for TL082AIYDT?

The device specifies 10–60 mA short-circuit output current depending on temperature and supply conditions. While short-circuit protection is built-in, sustained operation at maximum current must remain within the 680 mW total power dissipation limit - requiring thermal derating above +25 °C ambient per the 125 °C/W R_thJA.

Can TL082AIYDT operate from a single 24 V supply?

Yes - its 6–36 V supply range and ±11 V input common-mode range allow single-supply operation. For rail-to-rail input, a V_CC/2 reference must be applied to the non-inverting input; output swing remains limited to ~10 V peak-to-peak into 2 kΩ, so mid-supply biasing is required for AC-coupled signals.

Does TL082AIYDT require external compensation capacitors?

No - it features internal frequency compensation optimized for unity-gain stability. External capacitors are unnecessary for standard inverting/non-inverting configurations up to gain = 10. For higher gains or capacitive loads >100 pF, small series resistors (e.g., 10–50 Ω) at the output may improve phase margin without altering compensation network.
