Product details
Overview
TLC083CD from Texas Instruments is a dual-channel, wide-bandwidth (10 MHz), high-output-drive BiMOS operational amplifier optimized for single-supply operation from 4.5 V to 16 V. It delivers ±57 mA output drive, 16 V/µs positive slew rate, 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 TLC083CD datasheet, TLC083CD pinout, TLC083CD application, or TLC083CD equivalent, key selection criteria include its shutdown capability, rail-to-rail input common-mode range (GND to VDD–2 V), low 8.5 nV/√Hz input noise, and compatibility with 14-pin SOIC and 10-pin MSOP PowerPAD™ packages.
Technical Context
The TLC083CD integrates a low-noise CMOS front end with a high-current bipolar output stage in TI's LBC3 BiCMOS process, achieving both ultrahigh input impedance (>1 GΩ) and robust ±50-mA load driving capability. Its internal architecture supports independent channel shutdown via dedicated SHDN pins and ensures stable operation with capacitive loads up to 50 pF.
Designed for single-supply systems, it features an extended common-mode input range that includes ground, enabling direct interfacing with unipolar sensors and ADCs. The device maintains 10 MHz gain-bandwidth product and >80 dB CMRR across –40°C to 125°C, supporting automotive and industrial temperature-grade applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - enables stable closed-loop operation at audio and control loop frequencies up to 1 MHz with unity-gain stability. |
| Output Drive | ±57 mA - drives heavy loads such as 600 Ω audio lines or multiple parallel inputs without external buffers. |
| Slew Rate | +16 V/µs, –19 V/µs - supports fast transient response in pulse amplification and active filter stages. |
| Supply Range | 4.5 V to 16 V - operates directly from 5 V or 12 V rails without regulation, reducing BOM count. |
| Input Offset Voltage | 60 µV typ - minimizes DC error in precision instrumentation and low-level sensor signal amplification. |
| Shutdown Current | 125 µA per channel - reduces system power by >93% during idle periods in battery-powered or energy-conscious designs. |
| Input Noise | 8.5 nV/√Hz at 1 kHz - preserves signal integrity in low-amplitude sensor interfaces and microphone preamps. |
Pinout & Package
The TLC083CD is available in 14-pin SOIC (D package) and 10-pin MSOP PowerPAD™ (DGQ package). Pin functions are identical across packages; DGQ uses exposed thermal pad for enhanced thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7 | Channel 1/2 Output | Amplified output nodes capable of sourcing/sinking ±57 mA into resistive or moderate capacitive loads. |
| 2, 6 | Channel 1/2 Inverting Input | Inverting input terminals with 1000 GΩ differential input resistance and 22.9 pF common-mode capacitance. |
| 3, 5 | Channel 1/2 Non-Inverting Input | Non-inverting inputs supporting common-mode range from GND to VDD–2 V at full rated supply. |
| 4 | GND | Analog ground reference shared by both channels and shutdown logic; requires low-impedance PCB connection. |
| 8 | VDD | Positive supply rail (4.5–16 V); decoupling capacitor required within 1 cm for stability. |
| 9, 10 | Channel 1/2 Shutdown | Logic-controlled enable/disable inputs; <0.8 V disables channel, >2 V enables; no pull-up required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Operates with inputs down to GND and up to VDD–2 V-enables direct interface with unipolar sensors and DACs. |
| Independent dual-channel shutdown | Each amplifier can be disabled separately via dedicated SHDN pins, minimizing quiescent current in multi-stage circuits. |
| High-output-drive bipolar output stage | Delivers ±57 mA while maintaining low distortion (<0.012% THD+N at 1 kHz), eliminating need for external driver transistors. |
| Low-noise CMOS input stage | 8.5 nV/√Hz input voltage noise and 0.6 fA/√Hz input current noise support high-resolution signal acquisition. |
| Stable with capacitive loads | Maintains ≥32° phase margin with 50 pF load-supports direct driving of ADC input capacitors and long cables. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel high-output-drive op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL082CD | Lower bandwidth (3 MHz), higher input offset (3 mV max), no shutdown, ±10 mA output drive. | Lacks rail-to-rail input, unsuitable for GND-referenced sensors or low-voltage single-supply systems. | Select only if legacy design compatibility or cost sensitivity outweighs performance requirements. |
| OPA2350UA | Higher bandwidth (38 MHz), lower noise (7 nV/√Hz), but limited output drive (±50 mA), no shutdown, 5 V max supply. | Not rated for 12 V operation; unsuitable for industrial 12 V/24 V systems requiring wide supply range. | Prefer for high-speed, low-noise, low-voltage applications where shutdown is not required. |
Compared with TL082CD and OPA2350UA, the TLC083CD uniquely combines 10 MHz bandwidth, ±57 mA drive, shutdown capability, and 4.5–16 V operation-making it the only option supporting full-featured dual-channel performance across automotive, industrial, and audio domains without supply or layout compromises.

FAQ
What is the operating temperature range for the TLC083CD?
The TLC083CD is specified for the commercial temperature range of 0°C to 70°C. This is indicated by the "C" suffix in the part number. For extended industrial operation from –40°C to 125°C, the TLC083ID variant must be selected instead. The TLC083CD's electrical characteristics-including bandwidth, slew rate, and output drive-are guaranteed across its full 0°C to 70°C range.
Does the TLC083CD support rail-to-rail input operation?
Yes, the TLC083CD supports rail-to-rail input common-mode voltage from GND to VDD–2 V. This allows direct interfacing with ground-referenced sensors and unipolar DAC outputs without level-shifting circuitry. The specification is confirmed in the Recommended Operating Conditions table of the datasheet, where VICR is listed as GND to VDD–2 V at all supply voltages from 4.5 V to 16 V.
What package options are available for the TLC083CD?
The TLC083CD is offered in two standard packages: 14-pin SOIC (D package) and 10-pin MSOP PowerPAD™ (DGQ package). Both are surface-mount, RoHS-compliant, and support tape-and-reel ordering (add "R" suffix, e.g., TLC083CDR). The DGQ package includes an exposed thermal pad for improved power dissipation, while the D package offers broader board-level compatibility and easier prototyping.
How does the shutdown feature work on the TLC083CD?
The TLC083CD provides independent shutdown control for each channel via pins 9 (1/2SHDN) and 10 (1/2SHDN). Driving either pin to ≤0.8 V disables the corresponding amplifier, reducing its supply current to 125 µA. Driving the pin to ≥2 V enables normal operation. No external pull-up is required, and the shutdown logic is fully compatible with standard CMOS/TTL logic levels.
Can the TLC083CD drive a 600 Ω audio load at 1 kHz with low distortion?
Yes, the TLC083CD delivers <0.005% THD+N when driving a 600 Ω load at 1 kHz with 8 VPP output at 12 V supply, as verified in the Electrical Characteristics table under VDD = 12 V conditions. Its ±57 mA output drive and 19 V/µs negative slew rate ensure clean large-signal fidelity, making it suitable for professional audio line driver applications without external buffering.
