Product details
Overview
TLC080CDGN from Texas Instruments is a single-channel BiMOS operational amplifier optimized for wide-bandwidth, high-output-drive single-supply applications. 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 supply - enabling robust signal conditioning in audio line drivers and industrial sensor interfaces.
For engineers reviewing the TLC080CDGN datasheet, TLC080CDGN pinout, TLC080CDGN application, or TLC080CDGN 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 MSOP-8 PowerPAD™ package thermal performance.
Technical Context
The TLC080CDGN integrates a low-noise CMOS front end with a high-current bipolar output stage, enabling simultaneous high impedance (>1 GΩ differential input resistance), low offset (60 µV typical), and strong load driving (55 mA sink / 57 mA source) without external buffers. Its internal offset nulling pins support precision DC-coupled designs.
It features active shutdown control (SHDN pin), allowing per-channel power gating with 125 µA shutdown current. The device maintains stable operation up to 125°C and supports unity-gain stable configurations with ≥32° phase margin into 50 pF loads at 5 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - enables accurate amplification of signals up to audio and ultrasonic frequencies without gain roll-off. |
| Output Drive | ±57 mA - drives heavy loads such as 600 Ω audio lines or capacitive DAC buffers directly. |
| Slew Rate | +16 V/µs, –19 V/µs - preserves fast transient fidelity in pulse and video signal paths. |
| Supply Range | 4.5 V to 16 V - supports battery-powered (5 V/12 V) and industrial (15 V) single-rail systems. |
| Input Noise | 8.5 nV/√Hz @ 1 kHz - ensures minimal added noise in low-level sensor signal chains. |
| Shutdown Current | 125 µA/channel - reduces system standby power while retaining fast wake-up (<1.3 µs turnoff time). |
| Input Offset | 60 µV typ - minimizes DC error in precision instrumentation and closed-loop transducer interfaces. |
Pinout & Package
Package: 8-pin MSOP (DGN) with exposed thermal pad (PowerPAD™), 3.0 mm × 3.0 mm footprint, 0.65 mm pitch. Optimized for low thermal resistance (θJA = 52.7°C/W) and PCB heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NULL) | Offset Null | Connects to external potentiometer for fine-tuning input offset voltage to <1 mV. |
| 2 (IN–) | Inverting Input | Differential input node; high-impedance CMOS input (1000 GΩ) with low bias current (100 pA). |
| 3 (IN+) | Non-Inverting Input | Differential input node; supports common-mode range from GND to VDD–2 V. |
| 4 (GND) | Analog Ground | Reference return for input and output stages; must be tied to low-impedance ground plane. |
| 5 (SHDN) | Shutdown Control | Active-low logic input; pulls supply current to 125 µA when ≤0.8 V, enabling power sequencing. |
| 6 (VDD) | Positive Supply | Single supply input (4.5–16 V); powers both input and output stages; decoupling required. |
| 7 (OUT) | Amplifier Output | Class-AB bipolar output stage capable of sourcing/sinking ±57 mA into resistive or capacitive loads. |
| 8 (NULL) | Offset Null | Second terminal for external nulling potentiometer; used with Pin 1 for balanced offset adjustment. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | GND to VDD–2 V enables direct interfacing with unipolar sensors and ADC references without level-shifting. |
| Integrated shutdown function | Reduces quiescent current to 125 µA/channel, supporting low-power modes in portable and IoT edge nodes. |
| MSOP-8 PowerPAD™ package | Delivers 2.37 W power dissipation rating (θJC = 4.7°C/W), critical for sustained high-output-drive operation. |
| Low THD+N (0.005% @ 1 kHz) | Preserves signal integrity in audio line drivers and precision analog front-ends without post-amplifier filtering. |
| Stable into 50 pF capacitive loads | Maintains ≥32° phase margin without external compensation, simplifying layout for DAC output buffering. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2460CDGN | Lower bandwidth (6.4 MHz), lower output drive (±15 mA), no shutdown pin, same MSOP-8 package. | Not suitable for high-current line driving; better for low-power, low-noise sensor amps where shutdown is unnecessary. | Select TLV2460CDGN only if bandwidth and output current requirements are relaxed and shutdown is not needed. |
| OPA350UA | Higher bandwidth (38 MHz), lower noise (7 nV/√Hz), no shutdown, SO-8 package (not MSOP-8), higher supply current (4.9 mA). | Preferred for ultra-high-speed, low-noise applications but lacks shutdown and thermal advantages of PowerPAD™. | Choose OPA350UA when speed and noise dominate over power management and thermal performance. |
Compared with TLV2460CDGN and OPA350UA, the TLC080CDGN uniquely balances high output drive, integrated shutdown, and MSOP PowerPAD™ thermal efficiency - making it optimal for space-constrained, high-current, single-supply industrial and automotive signal paths where power sequencing matters.

FAQ
What is the operating temperature range for the TLC080CDGN?
The TLC080CDGN is rated for commercial operation from 0°C to 70°C (C-suffix). Its absolute maximum junction temperature is 150°C, and it maintains specified performance across this full range - including stable phase margin and output drive capability - making it suitable for enclosed industrial enclosures without forced cooling.
Does the TLC080CDGN support rail-to-rail input or output?
The TLC080CDGN supports rail-to-rail input common-mode range (GND to VDD–2 V) but does not provide rail-to-rail output swing. Its output typically swings within 1.5 V of each rail under load - e.g., 0.5 V to 3.5 V on a 5 V supply - which is sufficient for most single-supply sensor and line-driving applications.
How is the shutdown function implemented on the TLC080CDGN?
The TLC080CDGN uses an active-low SHDN pin (Pin 5). When pulled ≤0.8 V, it disables the amplifier core and reduces supply current to 125 µA per channel. The turnoff time is 1.3 µs and turnon time is 0.47 µs at 12 V supply - enabling rapid power cycling in battery-operated systems without latch-up risk.
Can the TLC080CDGN drive capacitive loads, and what is the maximum stable capacitance?
Yes, the TLC080CDGN is unity-gain stable and maintains ≥32° phase margin into 50 pF capacitive loads at 5 V supply. For heavier loads (e.g., >100 pF), external series resistance (≥10 Ω) at the output is recommended to preserve stability - a common practice when driving long cables or ADC input capacitors.
What is the purpose of the NULL pins (1 and 8) on the TLC080CDGN?
Pins 1 and 8 are offset null terminals. Connecting a 10 kΩ potentiometer between them, with the wiper grounded, allows precise adjustment of input offset voltage down to <1 mV - essential for DC-critical applications like precision weigh scales or medical sensor front-ends where zero-error calibration is mandatory.
