Product details
Overview
TLC082AIDR from Texas Instruments is a dual-channel, wide-bandwidth BiMOS operational amplifier optimized for single-supply operation (4.5 V to 16 V), delivering 10 MHz gain-bandwidth, ±57 mA output drive, and 16 V/µs positive slew rate. It operates across –40°C to 125°C and is used in high-fidelity audio line drivers, industrial sensor signal conditioning, and automotive body control modules requiring rail-to-rail input capability and robust output current.
For engineers reviewing the TLC082AIDR datasheet, TLC082AIDR pinout, TLC082AIDR application, or TLC082AIDR equivalent, key selection criteria include guaranteed ground-sensing common-mode input range (VICR = GND to VDD–2 V), ultralow 125 µA/channel shutdown current, and SOIC-8 package compatibility with legacy TL082 layouts while offering 3× bandwidth improvement.
Technical Context
The TLC082AIDR employs a BiMOS architecture combining a low-noise CMOS front end (8.5 nV/√Hz input voltage noise, 1000 GΩ differential input resistance) with a high-drive bipolar output stage. This enables simultaneous high dc precision (60 µV max input offset voltage) and dynamic performance (10 MHz GBW, 19 V/µs negative slew rate).
It supports true single-supply operation with VICR extending to ground and output swing within 0.5 V of rails under 50 mA load. The device lacks shutdown functionality-confirmed by absence of SHDN pin in TLC082 pinout and omission from TLC082 row in Family Package Table-distinguishing it from TLC080/TLC083 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - enables stereo audio buffering or differential sensor amplification in one package |
| Supply Range | 4.5 V to 16 V - supports 5 V, 12 V, and 15 V industrial and automotive rails without level-shifting |
| Gain-Bandwidth | 10 MHz - allows stable unity-gain buffer operation up to 10 MHz or closed-loop gain of 10 at 1 MHz |
| Output Drive | ±57 mA - drives 600 Ω loads directly (e.g., line-level audio into terminated cables) |
| Input Offset Voltage | 60 µV (max) - reduces dc error in precision instrumentation front ends without trimming |
| Common-Mode Range | GND to VDD–2 V - accepts 0 V referenced signals (e.g., thermocouple outputs) on single supply |
| Quiescent Current | 1.9 mA per channel - enables low-power operation in always-on sensor nodes |
Pinout & Package
Package: SOIC-8 (D package), 3.9 mm × 4.9 mm, surface-mount, industry-standard footprint compatible with TL082 and LM358 layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Amplified output node; capable of sourcing/sinking ±57 mA into resistive or capacitive loads |
| 2 | Channel 1 Inverting Input | Inverting summing node; high impedance (1000 GΩ) minimizes loading on feedback networks |
| 3 | Channel 1 Non-Inverting Input | Reference input for follower or non-inverting gain stages; supports ground-referenced signals |
| 4 | Ground | Power and signal reference plane; must be low-impedance for noise immunity in mixed-signal systems |
| 5 | Channel 2 Non-Inverting Input | Independent input for second channel; enables dual-path signal processing without crosstalk penalty |
| 6 | Channel 2 Inverting Input | Second channel's feedback node; supports independent gain configuration per channel |
| 7 | Channel 2 Output | Second independent output; identical drive strength and bandwidth as Pin 1 |
| 8 | VDD | Positive supply rail; accepts 4.5–16 V; no negative rail required for single-supply operation |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS input stage (low IB, low noise) with bipolar output (high IOUT, fast SR) - eliminates trade-off between precision and drive |
| Rail-to-Rail Input Capability | VICR includes ground (0 V) - enables direct interfacing with unipolar sensors (e.g., RTDs, current shunts) without level shifters |
| High Output Current | ±57 mA per channel - drives low-Z loads (e.g., 600 Ω audio lines, relay coils) without external buffers |
| Low Input Voltage Noise | 8.5 nV/√Hz at 1 kHz - preserves SNR in microphone preamps and strain gauge amplifiers |
| Wide Temperature Range | –40°C to +125°C - qualified for under-hood automotive and industrial control environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL082CDR | Lower bandwidth (3 MHz), higher input offset (10 mV max), no guaranteed ground-sensing VICR | Legacy designs where cost is primary concern and bandwidth <3 MHz suffices | Select TLC082AIDR when >5 MHz bandwidth, <100 µV VIO, or ground-referenced input is required |
| OPA2340UA | Rail-to-rail I/O, lower noise (7 nV/√Hz), but only 5.5 V max supply and ±20 mA output drive | Battery-powered portable instruments needing full rail swing and ultra-low power | Select TLC082AIDR for 12 V operation, higher output current, or extended temperature range beyond 85°C |
Compared with TL082CDR and OPA2340UA, the TLC082AIDR uniquely balances 10 MHz bandwidth, ±57 mA drive, ground-sensing input, and –40°C to 125°C operation-making it optimal for industrial and automotive signal chains where both precision and robustness are mandatory.

FAQ
What is the operating temperature range for the TLC082AIDR?
The TLC082AIDR is rated for operation from –40°C to +125°C, making it suitable for under-hood automotive applications and industrial environments with extreme thermal conditions. This extended temperature grade is confirmed by the "I" suffix in the part number and verified in the Recommended Operating Conditions table of the official datasheet.
Does the TLC082AIDR include a shutdown feature?
No, the TLC082AIDR does not include a shutdown function. The pinout diagram for TLC082 shows no SHDN terminal, and the Family Package Table explicitly lists "-" under the Shutdown column for TLC082. This distinguishes it from TLC080 and TLC083, which do support shutdown mode.
What is the maximum output current capability of the TLC082AIDR?
The TLC082AIDR delivers ±57 mA sourcing and sinking capability per channel, measured at VDD – 1.5 V (for IOH) and 0.5 V (for IOL). This high drive strength allows direct interfacing with low-impedance loads such as 600 Ω audio lines or relay driver circuits without external buffers.
Is the TLC082AIDR pin-compatible with the TL082?
Yes, the TLC082AIDR uses the standard SOIC-8 (D) package with identical pinout to the TL082, enabling drop-in replacement in existing designs. Both share the same 1–8 pin assignment: OUT1, IN1–, IN1+, GND, IN2+, IN2–, OUT2, VDD-verified in the TLC082 D-package top view diagram.
What is the input common-mode voltage range for the TLC082AIDR?
The TLC082AIDR supports a common-mode input voltage range from GND to VDD – 2 V, enabling true ground-sensing operation on single supplies. This is specified in the Recommended Operating Conditions table and confirmed by Figure 1 (VIO vs VICR) showing stable offset behavior down to 0 V at VDD = 5 V and 12 V.
