Product details
Overview
TLC080CD from Texas Instruments is a single-channel BiMOS operational amplifier optimized for wide-bandwidth, high-output-drive, single-supply operation. It delivers 10 MHz gain-bandwidth, ±57 mA output drive, 16 V/µs positive slew rate, and operates from 4.5 V to 16 V - enabling robust signal conditioning in audio line drivers and industrial sensor interfaces.
For engineers reviewing the TLC080CD datasheet, TLC080CD pinout, TLC080CD application, or TLC080CD equivalent, key selection criteria include its shutdown capability (SHDN pin), rail-to-rail input common-mode range (GND to VDD–2 V), low 8.5 nV/√Hz input noise, and SOIC-8 packaging with thermal performance validated up to 125°C.
Technical Context
The TLC080CD integrates a CMOS front end for ultralow input bias current (≤100 pA) and high input impedance (>1 GΩ), paired with a bipolar output stage enabling ±57 mA sourcing/sinking into heavy loads. Its BiMOS architecture ensures stable operation with capacitive loads up to 50 pF while maintaining ≥32° phase margin.
It features dedicated offset nulling pins (1 and 8), active shutdown control (pin 5), and guaranteed performance across 0°C to 70°C (C-suffix). The device supports unity-gain stable configurations and exhibits 100 dB CMRR and 100 dB PSRR at DC, making it suitable for precision analog front ends where supply rejection and common-mode immunity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - enables accurate amplification of signals up to audio and low-speed data rates without gain roll-off. |
| Output Drive | ±57 mA - drives 600 Ω audio loads or multiple logic inputs directly without external buffers. |
| Slew Rate | 16 V/µs (SR+) / 19 V/µs (SR–) - supports fast transient response in pulse amplification and active filtering. |
| Supply Range | 4.5 V to 16 V - compatible with single-supply 5 V and 12 V systems, eliminating need for dual rails. |
| Input Noise | 8.5 nV/√Hz - preserves signal integrity in low-level sensor amplification (e.g., thermocouples, strain gauges). |
| Shutdown Current | 125 µA/channel - reduces system power by >93% during idle periods in battery-powered instrumentation. |
| Input Offset | 60 µV (typ) - minimizes DC error in precision gain stages and closed-loop transimpedance designs. |
Pinout & Package
Package: SOIC-8 (D package), 3.9 mm × 4.9 mm, surface-mount, tape-and-reel capable (TLC080CDR variant available).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null | Connects to external potentiometer for trimming input offset voltage to <100 µV. |
| 2 | Inverting Input (IN–) | Differential input node; high-impedance CMOS input (≥1 GΩ) with 22.9 pF common-mode capacitance. |
| 3 | Noninverting Input (IN+) | Differential input node; supports common-mode range from GND to VDD–2 V at 5 V supply. |
| 4 | GND | Analog ground reference; must be low-impedance connection to minimize noise coupling. |
| 5 | Shutdown (SHDN) | Active-low digital control: ≤0.8 V disables amplifier, reducing IDD to 125 µA; ≥2 V enables full operation. |
| 6 | VDD | Positive supply rail; accepts 4.5 V–16 V; internal ESD protection rated to 2 kV HBM. |
| 7 | Output (OUT) | Class-AB output stage capable of ±57 mA; specified output impedance is 0.25 Ω at 10 kHz. |
| 8 | Offset Null | Second terminal of offset null network; used with Pin 1 for precision DC calibration. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Operates with inputs down to GND and up to VDD–2 V - eliminates level-shifting in single-supply sensor interfaces. |
| Integrated shutdown mode | Reduces quiescent current to 125 µA per channel - extends battery life in portable test equipment. |
| High-output-current bipolar stage | Delivers ±57 mA into 600 Ω loads - replaces discrete output buffers in audio line drivers and actuator interfaces. |
| Low-noise CMOS input stage | 8.5 nV/√Hz input voltage noise + 0.6 fA/√Hz input current noise - ideal for high-gain, low-frequency sensor signal chains. |
| Stable with capacitive loads | Maintains ≥32° phase margin with up to 50 pF load capacitance - simplifies layout in PCB-constrained applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL081CP | Lower bandwidth (4 MHz), no shutdown, higher input offset (3 mV max), BiFET input (higher noise: 18 nV/√Hz). | Lacks SHDN control and rail-to-rail input; unsuitable for battery-critical or precision DC-coupled designs. | Select TL081CP only if legacy compatibility or cost sensitivity outweighs performance and power advantages of TLC080CD. |
| OPA344UA | CMOS input (0.5 pA IIB), lower noise (11 nV/√Hz), but limited output drive (25 mA) and no shutdown pin. | No integrated shutdown; requires external enable circuitry; not rated for 125°C operation. | Choose OPA344UA when ultra-low input bias is mandatory (e.g., photodiode transimpedance), but accept trade-offs in drive strength and thermal rating. |
Compared with TL081CP and OPA344UA, the TLC080CD uniquely combines high output drive, integrated shutdown, rail-to-rail input, and 125°C-rated operation - making it the only option among the three qualified for automotive body control and industrial sensor front ends requiring both precision and robustness.

FAQ
What is the maximum operating temperature range for the TLC080CD?
The TLC080CD is rated for operation from 0°C to 70°C (commercial temperature range), as indicated by the "C" suffix in the part number. This is confirmed in the "TLC080 and TLC081 AVAILABLE OPTIONS" table and the Recommended Operating Conditions section of the datasheet, which specifies TA = 0°C to 70°C for C-suffix devices. The TLC080ID variant supports –40°C to 125°C.
Does the TLC080CD support rail-to-rail output swing?
No, the TLC080CD does not provide rail-to-rail output swing. Its output voltage swing is specified as VOH ≥ 3.2 V and VOL ≤ 0.7 V at VDD = 5 V and IO = ±50 mA. At VDD = 12 V, VOH ≥ 10.2 V and VOL ≤ 0.65 V. The datasheet confirms output headroom of ~1.5 V from each rail under heavy load, consistent with its bipolar output stage architecture.
How is the shutdown function implemented on the TLC080CD?
The TLC080CD uses an active-low shutdown pin (SHDN, Pin 5) that disables the amplifier core when pulled to ≤0.8 V, reducing supply current to 125 µA per channel. When SHDN ≥2 V, the device operates normally. Turnon/turnoff times are 0.15 µs and 1.3 µs respectively at 25°C, enabling rapid power cycling in responsive instrumentation systems.
Can the TLC080CD drive capacitive loads, and what is the stability limit?
Yes, the TLC080CD is stable with capacitive loads up to 50 pF, as verified by phase margin measurements of ≥32° in the Electrical Characteristics tables. The datasheet explicitly states stability under CL = 50 pF conditions and provides phase/gain margin vs. load capacitance plots (Figures 19–22), confirming robust behavior in PCB traces and filter networks without requiring isolation resistors.
What package types are available for the TLC080CD, and is lead-free compliance confirmed?
The TLC080CD is offered in the SOIC-8 (D) package, as confirmed in the "TLC080 and TLC081 AVAILABLE OPTIONS" table. TI's official documentation and packaging addenda confirm RoHS-compliant, lead-free construction for this variant. Tape-and-reel packaging is available as TLC080CDR, formed by adding an "R" suffix to the base part number.
