Product details
Overview
TLC082AIP 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 features rail-to-rail input common-mode range (including ground) and is used in audio line drivers, industrial sensor signal conditioning, and automotive body control modules requiring high-output-drive precision amplification.
For engineers reviewing the TLC082AIP datasheet, TLC082AIP pinout, TLC082AIP application, or TLC082AIP equivalent, key selection criteria include its guaranteed 125°C extended-temperature operation, ultralow 125 µA/channel shutdown current, and compatibility with 8-pin PDIP packaging for through-hole prototyping and legacy industrial PCBs.
Technical Context
The TLC082AIP 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-current bipolar output stage. This enables simultaneous high AC performance and robust DC accuracy across its full –40°C to 125°C operating range.
It supports true single-supply operation with VICR extending to ground and VDD–2 V, and includes no internal shutdown functionality-unlike TLC080/TLC083 variants-making it suitable for always-on signal paths where power gating is handled externally.
Key Specifications

|---|---|
| Bandwidth | 10 MHz - Enables stable unity-gain buffer operation up to 10 MHz and closed-loop amplification at higher gains within audio and instrumentation bands. |
| Output Drive | ±57 mA - Drives heavy loads such as 600 Ω audio lines or capacitive DAC buffers without external boost stages. |
| Slew Rate | +16 V/µs / –19 V/µs - Supports fast transient response in pulse amplification and active filter applications with minimal distortion. |
| Supply Range | 4.5 V to 16 V - Operates directly from 5 V logic rails or 12 V automotive systems without regulation. |
| Input Offset Voltage | Max 1400 µV (A-grade, full temp range) - Ensures sub-mV error in precision DC-coupled sensor interfaces at temperature extremes. |
| Supply Current | 1.9–2.9 mA per channel - Balances low quiescent power with high-speed capability for battery-aware industrial designs. |
| Operating Temp | –40°C to +125°C - Qualified for under-hood automotive, motor control feedback, and harsh-environment industrial use. |

Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Operates with inputs from GND to VDD–2 V-enables direct interfacing with unipolar sensors and ADC references without level-shifting. |
| High-output-drive bipolar output stage | Delivers ±57 mA while maintaining linearity-eliminates need for external driver transistors in line-driver and actuator-control circuits. |
| Low input voltage noise | 8.5 nV/√Hz at 1 kHz-preserves SNR in low-level signal amplification (e.g., thermocouple, strain gauge, microphone preamps). |
| Extended temperature grade (I-suffix) | Specified over –40°C to +125°C-qualified for automotive engine compartments and industrial motor drives without derating. |

Applications
| Audio Line Driver | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Driving balanced/unbalanced 600 Ω audio lines from DAC outputs in professional audio mixers and broadcast equipment. IC Role / Device Role / Timing Role: Dual-channel voltage buffer and level shifter, providing low-distortion, high-current output with minimal THD+N (0.005% at 1 kHz, 8 VPP, 12 V supply). Use Value: Eliminates external emitter-follower stages while maintaining <0.01% THD+N up to 20 kHz, reducing BOM count and PCB area. | Use Scenario: Amplifying millivolt-level outputs from RTDs, thermocouples, or bridge-based pressure sensors in PLC analog input modules. IC Role / Device Role / Timing Role: Precision instrumentation amplifier front-end (configured as difference amplifier or PGA), leveraging low VIO (1400 µV max) and high CMRR (80 dB). Use Value: Maintains <10 µV offset drift over –40°C to 125°C, enabling 16-bit-equivalent resolution without frequent calibration. |
| Automotive Body Control Unit | Motor Control Current Sense Amplifier |
Use Scenario: Signal conditioning for door lock actuators, mirror position sensors, and ambient light detection in vehicle body electronics. IC Role / Device Role / Timing Role: Dual-channel general-purpose op-amp for sensor biasing, signal buffering, and PWM-filtered DAC output smoothing. Use Value: Guaranteed operation at 125°C ambient allows placement near ECUs or power distribution centers without thermal derating or heatsinking. | Use Scenario: High-side or low-side current sensing in BLDC motor inverters, where fast response and high common-mode rejection are critical. IC Role / Device Role / Timing Role: Current-sense amplifier configured in differential mode, rejecting bus noise while amplifying shunt voltage with 10 MHz bandwidth. Use Value: 19 V/µs negative slew rate ensures accurate capture of fast current transients during PWM switching edges (e.g., 20 kHz gate drive). |
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 |
|---|---|---|---|
| TLC082CD | Same architecture and pinout; commercial-grade (0°C to 70°C) with higher max VIO (1900 µV) and no 125°C qualification. | Suitable only for benign environments (office equipment, consumer audio); not qualified for automotive or industrial edge cases. | Select TLC082CD only when cost sensitivity outweighs temperature reliability requirements and ambient stays below 70°C. |
| OPA2340UA | Rail-to-rail I/O, lower Vn (7 nV/√Hz), but lower output drive (±30 mA) and narrower bandwidth (5.5 MHz); SO-8 package only. | Better for ultra-low-noise, low-power portable instruments; insufficient for 600 Ω line driving or high-current pulse loads. | Choose OPA2340UA when noise dominates over drive strength and board space favors SOIC over PDIP. |
Compared with TLC082CD, the TLC082AIP provides guaranteed 125°C operation and tighter offset specs, making it superior for automotive and industrial deployments; versus OPA2340UA, it trades some noise performance for significantly higher output current and bandwidth-critical for driving reactive or low-impedance loads.

FAQ
What is the maximum operating temperature of the TLC082AIP?
The TLC082AIP is rated for continuous operation from –40°C to +125°C, meeting the extended industrial temperature grade (I-suffix). This specification is fully tested and guaranteed per the SLOS254F datasheet, making the TLC082AIP suitable for under-hood automotive applications and high-ambient industrial environments where standard commercial-grade op-amps would fail.
Does the TLC082AIP have a shutdown pin?
No, the TLC082AIP does not include a shutdown pin or internal power-down circuitry. Unlike the TLC080 or TLC083 variants, this device is designed for fixed-operation applications. Power management must be implemented externally-for example, by controlling the VDD rail or using series FETs-since the TLC082AIP draws 1.9–2.9 mA per channel continuously when powered.
What is the input common-mode voltage range of the TLC082AIP?
The TLC082AIP supports a rail-to-rail input common-mode voltage range from GND to VDD–2 V across its full operating temperature range. At VDD = 12 V, this means inputs can swing from 0 V to 10 V; at VDD = 5 V, from 0 V to 3 V. This feature enables direct interfacing with unipolar sensors, DACs, and microcontroller ADC references without level-shifting circuitry.
Can the TLC082AIP drive a 600 Ω load effectively?
Yes, the TLC082AIP is explicitly characterized to drive ±57 mA into loads, which corresponds to >±34 V peak-to-peak into 600 Ω at 12 V supply. Its high-output-drive bipolar stage maintains low distortion (THD+N = 0.005% at 1 kHz, 8 VPP) and stable phase margin even with 50 pF capacitive loading-making it ideal for professional audio line-driving applications without external buffers.
What package type is used for the TLC082AIP?
The TLC082AIP uses an 8-pin Plastic Dual Inline Package (PDIP), designated by the "P" suffix in TI's ordering nomenclature. This through-hole package supports manual prototyping, legacy industrial PCBs, and applications requiring mechanical robustness and ease of socketing or rework-distinct from surface-mount variants like TLC082IDGN (MSOP) or TLC082CD (SOIC).
