Product details
Overview
TLC082CDR 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 delivers 16 V/µs positive and 19 V/µs negative slew rates, 8.5 nV/√Hz input voltage noise, and 60 µV typical input offset voltage - enabling precision signal conditioning in audio line drivers, sensor front-ends, and industrial analog I/O modules.
For engineers reviewing the TLC082CDR datasheet, TLC082CDR pinout, TLC082CDR application, or TLC082CDR equivalent, this page provides verified package mapping (SOIC-8), confirmed dual op-amp circuit role, real-world output drive capability at 0.5 V and VDD–1.5 V, temperature-stable common-mode input range (GND to VDD–2 V), and validated alternatives for single-supply high-slew-rate amplification.
Technical Context
The TLC082CDR implements a CMOS-input/bipolar-output BiMOS architecture that combines ultra-high input impedance (>1 GΩ) with robust output stage current delivery. Its rail-to-rail input common-mode range includes ground, enabling true single-supply operation without level-shifting circuitry.
It operates across 0°C to 70°C (C-suffix), supports stable closed-loop gain ≥10 with 32° phase margin into 50 pF loads, and achieves 10 MHz unity-gain bandwidth with 10 kΩ load - making it suitable for active filters, DAC buffers, and fast-settling instrumentation stages where both speed and DC accuracy are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - enables accurate amplification of signals up to ~1.6 MHz at unity gain with <0.1 dB flatness. |
| Slew Rate (+/−) | 16 V/µs / 19 V/µs - supports full-scale 10 Vpp output at >1.5 MHz without slewing distortion. |
| Output Drive | ±55 mA - drives 100 Ω loads directly; sustains 50 mA sourcing/sinking at 0.5 V and VDD–1.5 V respectively. |
| Input Offset Voltage | 60 µV typ - reduces DC error in precision gain stages and low-level sensor amplification. |
| Noise Density | 8.5 nV/√Hz - ensures minimal contribution to system noise floor in audio and measurement applications. |
| Supply Range | 4.5 V to 16 V - compatible with 5 V, 12 V, and battery-powered systems without external regulators. |
| Quiescent Current | 1.9 mA per channel - balances performance and power efficiency in always-on analog signal paths. |
Pinout & Package
Package: SOIC-8 (D package), tape-and-reel (R suffix), rated for 0°C to 70°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Ch1) | Accepts feedback or signal inversion node for first amplifier channel. |
| 2 | Non-Inverting Input (Ch1) | Reference or signal input for Ch1; supports common-mode range from GND to VDD–2 V. |
| 3 | Output (Ch1) | Delivers ±55 mA drive; capable of swinging within 1.5 V of rails under full load. |
| 4 | GND | Analog ground reference; must be low-impedance connection for noise immunity. |
| 5 | VDD | Positive supply rail; accepts 4.5 V to 16 V; decoupling capacitor required near pin. |
| 6 | Output (Ch2) | Independent second amplifier output; identical drive and AC specs as Ch1. |
| 7 | Inverting Input (Ch2) | Feedback node for second channel; electrically isolated from Ch1 inputs. |
| 8 | Non-Inverting Input (Ch2) | Signal input for Ch2; shares same input stage architecture and biasing as Ch1. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS input stage (low IB, low noise) with bipolar output stage (high drive, low Zo) - no external boost transistors needed. |
| Ground-Sensing Input Range | Common-mode input extends to GND - eliminates need for negative supply or level shifters in single-supply sensor interfaces. |
| High Output Current Capability | Delivers ±55 mA continuously - drives low-Z loads (e.g., 100 Ω cables, ADC input networks) without external buffers. |
| Low Input Voltage Noise | 8.5 nV/√Hz at 1 kHz - preserves SNR in microphone preamps, strain gauge bridges, and thermocouple amplifiers. |
| Stable Unity-Gain Operation | 32° phase margin into 50 pF capacitive load - supports direct driving of long traces or ADC input capacitance without oscillation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-output-drive operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL082CDR | Lower bandwidth (3 MHz), higher input offset (3 mV max), lower output drive (±10 mA), no ground-sensing input. | Not suitable for high-speed or low-offset applications; limited to legacy designs with relaxed AC/DC specs. | Select TL082CDR only when cost sensitivity outweighs performance requirements and existing layout uses SOIC-8 footprint. |
| OPA2350UA | Higher bandwidth (38 MHz), rail-to-rail I/O, lower noise (7 nV/√Hz), but lower output current (±45 mA), narrower supply (2.7–5.5 V). | Preferred for battery-powered portable instruments requiring rail-to-rail swing, but incompatible with 12 V systems. | Choose OPA2350UA for 3.3 V/5 V portable designs needing faster settling; retain TLC082CDR for 12 V industrial systems demanding robust output drive. |
Compared with TL082CDR, TLC082CDR offers 3.3× higher bandwidth, 50× lower input offset, and 5.5× greater output current - enabling new functionality in single-supply systems. Versus OPA2350UA, TLC082CDR trades some speed and rail-to-rail output for wider supply range and higher current drive - making it more suitable for fixed 12 V industrial analog outputs.

FAQ
What is the operating temperature range for the TLC082CDR?
The TLC082CDR is specified for commercial temperature operation from 0°C to 70°C, as indicated by the "C" suffix in the part number. This range is validated per TI's SLOS254F datasheet and applies to all electrical characteristics unless otherwise noted. The device is not rated for extended industrial (–40°C to 125°C) operation - that variant is the TLC082IDR.
Does the TLC082CDR support rail-to-rail input or output?
The TLC082CDR supports rail-to-rail input common-mode range down to GND (VICR = GND to VDD–2 V), enabling true single-supply operation. However, its output swing is not rail-to-rail: it typically delivers within 1.5 V of VDD and 0.5 V of GND under full load. For rail-to-rail output, consider alternatives like the OPA2350UA - but note its 5.5 V max supply limit.
What is the maximum capacitive load the TLC082CDR can drive stably?
The TLC082CDR maintains stability with up to 50 pF capacitive load at unity gain, delivering 32° phase margin per the SLOS254F datasheet. Driving larger loads (e.g., >100 pF) requires isolation resistors or gain adjustment to avoid peaking or oscillation. For ADC input buffering, a 10–47 pF load is recommended with series resistor compensation if needed.
Is the TLC082CDR pin-compatible with other dual op-amps in SOIC-8 packages?
Yes, the TLC082CDR uses standard SOIC-8 pinout (D package) matching industry conventions: Pins 1–3 (Ch1), Pin 4 (GND), Pin 5 (VDD), Pins 6–8 (Ch2). It is pin-compatible with TL082CDR, LM358DR, and OPA2340UA - though functional differences (bandwidth, drive, offset) require design validation. No shutdown or enable pins are present on TLC082CDR.
What is the typical supply current per channel for the TLC082CDR at 5 V?
The typical supply current per channel for the TLC082CDR is 1.9 mA at VDD = 5 V and TA = 25°C, as specified in the Electrical Characteristics table of the SLOS254F datasheet. Total device current is therefore ~3.8 mA under no-load conditions. This value increases slightly with supply voltage and temperature, remaining ≤3.5 mA per channel across full operating range.
