Product details
Overview
TLC082CP from Texas Instruments is a dual-channel, wide-bandwidth (10 MHz), high-output-drive (±55 mA) BiMOS operational amplifier optimized for single-supply operation from 4.5 V to 16 V. It features ultralow input offset voltage (60 µV typ), low input noise (8.5 nV/√Hz), and rail-to-rail input common-mode range including ground - enabling precision signal conditioning in audio line drivers, sensor front-ends, and industrial analog I/O modules.
For engineers reviewing the TLC082CP datasheet, TLC082CP pinout, TLC082CP application, or TLC082CP equivalent, key selection criteria include its 16 V/µs positive slew rate, 1.9 mA/channel supply current, shutdown capability (125 µA/channel), and compatibility with 8-pin PDIP packaging for through-hole prototyping and legacy industrial designs.
Technical Context
The TLC082CP employs TI's LBC3 BiCMOS process, integrating a low-noise CMOS input stage with a high-current bipolar output stage to achieve simultaneous high AC performance and robust DC precision. Its architecture supports stable unity-gain operation with up to 50 pF capacitive load and delivers full-swing output into ±50-mA loads without external boost circuitry.
Unlike earlier TL08x predecessors, the TLC082CP ensures guaranteed common-mode input range down to ground across temperature, offers 4× lower input offset voltage (max 1.5 mV), and improves power supply rejection by >40 dB to 130 dB - making it suitable for mixed-signal systems where supply ripple and ground-referenced signals coexist.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - enables accurate amplification of audio and control-loop signals up to 100 kHz with minimal phase lag. |
| Slew Rate (+) | 16 V/µs - supports fast transient response in pulse amplification and active filter applications. |
| Output Drive | ±55 mA - drives heavy loads like 600-Ω audio lines or relay coils directly without external buffers. |
| Supply Range | 4.5 V to 16 V - operates from single Li-ion battery (4.5 V) up to industrial 12-V rails without level-shifting. |
| Input Offset Voltage | 60 µV typical - reduces DC error in precision instrumentation and sensor gain stages. |
| Noise Density | 8.5 nV/√Hz at 1 kHz - preserves signal integrity in low-level transducer interfaces. |
| Shutdown Current | 125 µA/channel - enables power gating in battery-powered multi-channel systems. |
Pinout & Package
Package: 8-pin plastic DIP (PDIP), through-hole mount, 0°C to 70°C operating range (C-suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Channel 1 output - delivers full-swing signal with ±55 mA sourcing/sinking capability. |
| 2 | 1IN– | Inverting input - high-impedance node (1 TΩ) for feedback network connection. |
| 3 | 1IN+ | Non-inverting input - accepts ground-referenced signals due to rail-to-rail VICR. |
| 4 | GND | Analog ground reference - shared return path for both channels and supply decoupling. |
| 5 | 2IN+ | Non-inverting input - independent channel 2 input, identical DC and AC specs to Pin 3. |
| 6 | 2IN– | Inverting input - matched to Pin 2 for dual-channel differential or parallel configurations. |
| 7 | 2OUT | Channel 2 output - electrically isolated from Channel 1; supports independent loading. |
| 8 | VDD | Positive supply - powers both op-amps; requires local 0.1-µF ceramic decoupling to GND. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Includes ground (0 V) to VDD – 2 V - eliminates need for level-shifting in single-supply sensor interfaces. |

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 |
|---|---|---|---|
| TL082CP | Lower bandwidth (3 MHz), higher input offset (3 mV max), no rail-to-rail input, 1.4 mA/channel supply current. | Limited to non-ground-referenced inputs; unsuitable for low-voltage sensor interfaces requiring VICR = 0 V. | Choose only if cost sensitivity outweighs performance requirements and legacy design reuse is critical. |
| OPA2340UA | Rail-to-rail I/O, lower noise (7 nV/√Hz), lower supply current (750 µA/channel), but reduced output drive (25 mA) and narrower supply range (2.7–5.5 V). | Optimized for low-voltage battery-powered systems; cannot replace TLC082CP in 12-V industrial or audio line-driving roles. | Select when operating from 3.3 V or 5 V and prioritizing ultra-low power over high-current drive. |
Compared with TL082CP and OPA2340UA, the TLC082CP uniquely balances 10-MHz bandwidth, ±55-mA drive, rail-to-rail input, and 4.5–16-V operation - making it the only option among the three capable of driving 600-Ω audio loads from 12-V supplies while preserving precision DC performance.

FAQ
What is the maximum supply voltage rating for the TLC082CP?
The TLC082CP has an absolute maximum supply voltage of 17 V, with recommended operation from 4.5 V to 16 V. Operating at 16 V ensures full specification compliance across the 0°C to 70°C temperature range, including output swing, slew rate, and load drive capability. Exceeding 17 V risks permanent device damage per the Absolute Maximum Ratings table in the SLOS254F datasheet.
Does the TLC082CP support rail-to-rail input operation?
Yes, the TLC082CP supports rail-to-rail input common-mode voltage range from GND to VDD – 2 V. This allows direct interfacing with ground-referenced sensors and single-supply ADCs without level-shifting circuitry. The feature is guaranteed across the full 0°C to 70°C operating range and is explicitly confirmed in the Recommended Operating Conditions table of the TLC082CP datasheet.
What is the typical output current capability of the TLC082CP per channel?
The TLC082CP delivers ±55 mA per channel under specified conditions: VOL = 0.5 V above GND and VOH = 1.5 V below VDD. This output drive is measured at room temperature with VDD = 5 V or 12 V and is sufficient to drive 600-Ω audio lines, relay coils, and industrial 4–20 mA loop transmitters without external buffering - as verified in the Electrical Characteristics tables of the SLOS254F datasheet.
Is the TLC082CP pin-compatible with the TL082CP?
No, the TLC082CP is not pin-compatible with the TL082CP. While both are 8-pin dual op-amps in PDIP packages, the TLC082CP uses standard dual-op-amp pinout (1OUT, 1IN–, 1IN+, GND, 2IN+, 2IN–, 2OUT, VDD), whereas TL082CP follows the legacy JFET-input configuration (1OUT, 1IN–, 1IN+, VDD, 2IN+, 2IN–, 2OUT, GND). Swapping them without PCB revision will cause incorrect power and ground connections.
What is the typical input offset voltage of the TLC082CP at 25°C?
The typical input offset voltage of the TLC082CP at 25°C is 60 µV, with a maximum of 1.5 mV across the full 0°C to 70°C operating range. This value is specified under VDD = 5 V and VIC = 2.5 V conditions in the Electrical Characteristics section of the SLOS254F datasheet and reflects the precision achievable in low-drift sensor amplifier and instrumentation applications.
