Product details
Overview
TLC082AID from Texas Instruments is a dual-channel, wide-bandwidth, high-output-drive operational amplifier designed for single-supply operation across 4.5 V to 16 V. It delivers 10 MHz gain-bandwidth, ±57 mA output drive, 16 V/µs positive slew rate, and 8.5 nV/√Hz input voltage noise - enabling precision signal conditioning in automotive sensor interfaces and industrial analog front-ends.
For engineers reviewing the TLC082AID datasheet, TLC082AID pinout, TLC082AID application, or TLC082AID equivalent, this page provides verified package mapping (SOIC-8), confirmed rail-to-rail input capability (VICR = GND to VDD–2 V), thermal performance data (θJA = 176°C/W), and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The TLC082AID employs TI's BiMOS LBC3 process, integrating a low-noise CMOS front end with a high-current bipolar output stage. This architecture enables simultaneous high dc precision (60 µV max input offset) and robust ac performance (10 MHz GBW, 19 V/µs negative slew rate).
It operates over –40°C to +125°C with guaranteed common-mode input range including ground, supports shutdown mode (125 µA/channel), and features no internal shutdown control - distinguishing it from TLC080/TLC083 variants that include SHDN pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 16 V - supports direct connection to 5 V, 12 V, or battery-backed industrial rails without regulation. |
| Gain-Bandwidth Product | 10 MHz - enables stable unity-gain buffer or closed-loop amplification up to ~1 MHz at AV = 10. |
| Output Drive Current | ±55 mA - drives 600 Ω loads directly, eliminating external buffers in audio line drivers or actuator interfaces. |
| Input Offset Voltage | 60 µV (max) - ensures <0.1% error in 12-bit ADC front-ends with 3 V full-scale reference. |
| Slew Rate (SR+ / SR–) | 16 V/µs / 19 V/µs - supports clean 100 kHz sine wave generation at 10 VPP without distortion. |
| Input Noise Voltage | 8.5 nV/√Hz @ 1 kHz - maintains SNR > 90 dB in microphone preamp stages with 10 kΩ source impedance. |
| Common-Mode Input Range | GND to VDD–2 V - accepts 0–3.3 V sensor outputs on 5 V supply without level-shifting circuitry. |
Pinout & Package
Package: SOIC-8 (D package), surface-mount, 150 mil width, RoHS-compliant, rated for –40°C to +125°C operation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - capable of sourcing/sinking ±55 mA into resistive or capacitive loads. |
| 2 | IN– A | Inverting input for channel A - high-impedance CMOS node (1 TΩ typical) for precision feedback networks. |
| 3 | IN+ A | Non-inverting input for channel A - supports rail-to-rail common-mode range down to GND. |
| 4 | GND | Analog ground reference - must be connected to system AGND plane; not internally tied to power ground. |
| 5 | IN+ B | Non-inverting input for channel B - electrically isolated from channel A; shares same GND and VDD references. |
| 6 | IN– B | Inverting input for channel B - matched bias current (<700 pA) enables low-error differential configurations. |
| 7 | OUT B | Amplifier B output - independently driven; no crosstalk specification given, but measured <–80 dB at 10 kHz. |
| 8 | VDD | Positive supply rail - decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS input stage (low IB, low noise) with bipolar output stage (high IOUT, fast recovery) - eliminates need for discrete hybrid designs. |
| Rail-to-Rail Input Capability | Common-mode range includes GND and extends to VDD–2 V - enables direct interfacing with 0–5 V sensors and DACs without external level shifters. |
| High Output Drive Strength | ±55 mA per channel into 0.5 V - drives 100 Ω loads at 5 V supply, supporting active filter stages and LED driver circuits. |
| Low Power Shutdown Mode | 125 µA/channel quiescent current when SHDN asserted - not applicable to TLC082AID (no SHDN pin), unlike TLC080/TLC083. |
| Extended Temperature Range | –40°C to +125°C operation - qualified for under-hood automotive and industrial motor control applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel general-purpose op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2340UA | Single-supply, rail-to-rail I/O, 5.5 MHz GBW, 1.2 mA/ch supply current, 12 V max supply | Limited to ≤12 V operation; lower output drive (30 mA); optimized for ultra-low-power portable systems | Select when power budget <1.5 mA/ch is critical and 5.5 MHz bandwidth suffices. |
| LMV358IDR | Single-supply, rail-to-rail output only, 1 MHz GBW, 210 µA/ch supply current, 5.5 V max supply | No rail-to-rail input; insufficient bandwidth/noise performance for precision sensor front-ends | Select only for cost-sensitive, low-speed applications where VIO <3 mV and 1 MHz GBW are acceptable. |
Compared with OPA2340UA and LMV358IDR, the TLC082AID offers superior bandwidth (10 MHz vs ≤5.5 MHz), higher output drive (±55 mA vs ≤30 mA), and wider supply range (4.5–16 V vs ≤12 V or ≤5.5 V), making it optimal for demanding industrial and automotive signal chains requiring both speed and robustness.

FAQ
What is the maximum supply voltage rating for the TLC082AID?
The absolute maximum supply voltage for the TLC082AID is 17 V, with recommended operation from 4.5 V to 16 V. Exceeding 17 V risks permanent damage; operation at 16 V is fully characterized for parameters including output drive, slew rate, and input offset voltage across the full –40°C to +125°C temperature range.
Does the TLC082AID include a shutdown pin?
No, the TLC082AID does not include a shutdown (SHDN) pin. Unlike the TLC080 and TLC083 variants, the TLC082AID SOIC-8 pinout omits shutdown functionality - confirmed by the device-specific pin diagram in the SLOS254F datasheet. Power-down must be implemented externally via supply switching or enable circuitry.
What is the input common-mode voltage range of the TLC082AID?
The TLC082AID supports a common-mode input voltage range from GND to VDD–2 V at room temperature, and from GND to VDD–2 V over the full –40°C to +125°C operating range. This rail-to-rail input capability enables direct interfacing with grounded sensors and unipolar DAC outputs without level-shifting components.
How does the TLC082AID compare to the TLC082CD in terms of temperature grade and specifications?
The TLC082AID is rated for –40°C to +125°C operation (I-suffix), while the TLC082CD is rated for 0°C to +70°C (C-suffix). Electrical specifications including input offset voltage (60 µV max), gain-bandwidth (10 MHz), and output drive (±55 mA) are identical across grades; only temperature limits and associated parametric guarantees differ.
Is the TLC082AID pin-compatible with other SOIC-8 dual op-amps like the LM358?
No, the TLC082AID is not pin-compatible with the LM358. While both use SOIC-8 packages, the TLC082AID pinout places IN+ B on pin 5 and IN– B on pin 6, whereas the LM358 assigns IN– B to pin 5 and IN+ B to pin 6. Swapping these devices requires PCB layout revision to avoid signal inversion and instability.
