Product details
Overview
TLC080IDGN from Texas Instruments is a single-channel, wide-bandwidth BiMOS operational amplifier optimized for single-supply operation (4.5 V to 16 V), delivering 10 MHz gain-bandwidth, ±57 mA output drive, and 16 V/µs positive slew rate. It features shutdown capability, rail-to-rail input common-mode range (including ground), and ultralow 125 µA shutdown current per channel - used in high-fidelity audio line drivers and industrial sensor signal conditioning.
For engineers reviewing the TLC080IDGN datasheet, TLC080IDGN pinout, TLC080IDGN application, or TLC080IDGN equivalent, key selection criteria include its MSOP-8 PowerPAD™ package with thermal performance (θJA = 52.7°C/W), guaranteed −40°C to +125°C operation, and high-output-drive capability into heavy loads without external buffers.
Technical Context
The TLC080IDGN integrates a low-noise CMOS front end with a high-current bipolar output stage in TI's LBC3 BiCMOS process, enabling both high input impedance (>1 GΩ) and robust output sourcing/sinking. Its internal offset nulling pins support precision DC-coupled designs, while the dedicated SHDN pin provides fast enable/disable control (ton = 0.47 µs at VDD = 12 V).
Designed for single-supply systems, it achieves full input voltage range from GND to VDD−2 V and delivers symmetrical output swing within 0.5 V of rails under 50 mA load. The device maintains stability with capacitive loads up to 50 pF and exhibits 37° phase margin at 12 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - supports audio and medium-speed data acquisition without external compensation. |
| Output Drive | ±57 mA - drives 600 Ω loads directly, eliminating need for external buffer stages. |
| Slew Rate | +16 V/µs / −19 V/µs - enables clean 10 VPP signals at >100 kHz without distortion. |
| Supply Range | 4.5 V to 16 V - operates across automotive battery (12 V) and industrial 5 V/15 V rails. |
| Input Offset | 60 µV typical - ensures <1 mV error in precision 12-bit ADC front ends at room temperature. |
| Shutdown Current | 125 µA/channel - reduces system standby power by >90% vs active mode (1.9 mA). |
| Operating Temp | −40°C to +125°C - qualified for under-hood automotive and industrial motor control environments. |
Pinout & Package
Package: 8-pin MSOP PowerPAD™ (DGN) with exposed thermal pad for enhanced heat dissipation (θJA = 52.7°C/W, θJC = 4.7°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NULL) | Offset Null | Connects to external potentiometer for fine-tuning input offset voltage to <10 µV. |
| 2 (IN–) | Inverting Input | Differential input node; high-impedance CMOS input (1000 GΩ) minimizes loading on sensor sources. |
| 3 (IN+) | Non-Inverting Input | Supports rail-to-rail common-mode range (GND to VDD−2 V) for single-supply signal acquisition. |
| 4 (GND) | Analog Ground | Reference for input/output and shutdown logic; must be tied to PCB ground plane beneath PowerPAD. |
| 5 (SHDN) | Shutdown Control | Active-low logic input; pulls supply current to 125 µA when ≤0.8 V, enabling power-gating in battery systems. |
| 6 (VDD) | Positive Supply | Single supply input (4.5–16 V); internal regulation ensures stable bias over wide voltage range. |
| 7 (OUT) | Amplifier Output | Class-AB bipolar output stage delivers ±57 mA into resistive loads or drives 50 pF capacitive loads stably. |
| 8 (NULL) | Offset Null | Second terminal for external nulling network; paired with Pin 1 for balanced offset trimming. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Includes ground reference - enables direct interfacing with unipolar sensors (e.g., thermocouples, RTDs) without level-shifting. |
| MSOP PowerPAD™ thermal package | 4.7°C/W junction-to-case resistance - sustains 2.37 W power dissipation at TA = 25°C, critical for high-output-drive applications. |
| Low input noise voltage | 8.5 nV/√Hz at 1 kHz - preserves SNR in microphone preamps and strain-gauge amplifiers with gain >100. |
| High CMRR & PSRR | 110 dB CMRR / 100 dB PSRR - rejects power supply ripple and common-mode interference in noisy industrial environments. |
| Fast shutdown response | toff = 2.5 µs at VDD = 12 V - meets real-time power cycling requirements in portable test equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-output-drive operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2376AIDR | Lower output drive (±25 mA), no shutdown pin, 5.5 MHz GBW, 7.5 nV/√Hz noise | Better for low-noise, low-power precision apps; unsuitable for 600 Ω loads or fast shutdown | Select TLC080IDGN when ≥±50 mA drive or active power gating is required. |
| LM7321MAX/NOPB | Higher quiescent current (2.5 mA), no shutdown, 20 MHz GBW, ±80 mA drive, same MSOP-8 package | Superior speed and drive but lacks shutdown and has higher static power | Choose LM7321MAX/NOPB only if shutdown is unnecessary and >10 MHz bandwidth is critical. |
Compared with OPA2376AIDR and LM7321MAX/NOPB, the TLC080IDGN uniquely balances high output drive, integrated shutdown, and thermal efficiency in an MSOP-8 PowerPAD™ package - making it optimal for space-constrained, power-aware industrial and automotive signal chains where load driving and standby power matter.

FAQ
What is the maximum supply voltage rating for the TLC080IDGN?
The TLC080IDGN has an absolute maximum supply voltage (VDD) of 17 V, with recommended operating range from 4.5 V to 16 V. Operation at 16 V enables full output swing into heavy loads while maintaining stability and thermal safety within its MSOP PowerPAD™ package limits.
Does the TLC080IDGN support rail-to-rail input operation?
Yes, the TLC080IDGN supports rail-to-rail input common-mode voltage from GND to VDD−2 V. This allows direct connection to unipolar sensors and single-supply ADCs without external level-shifting circuitry, simplifying design in battery-powered and industrial systems.
How does the shutdown feature of the TLC080IDGN function electrically?
The TLC080IDGN's SHDN pin is active-low: pulling it ≤0.8 V disables the amplifier and reduces supply current to 125 µA per channel. At VDD = 12 V, turnoff time is 2.5 µs, enabling rapid power cycling in portable instrumentation and energy-conscious control systems.
What thermal advantages does the MSOP PowerPAD™ package provide for the TLC080IDGN?
The MSOP PowerPAD™ (DGN) package delivers θJA = 52.7°C/W and θJC = 4.7°C/W, allowing the TLC080IDGN to dissipate up to 2.37 W at TA = 25°C. This thermal performance supports sustained ±57 mA output drive without derating in compact industrial modules.
Can the TLC080IDGN drive a 600 Ω load at 10 VPP without distortion?
Yes - the TLC080IDGN delivers ±57 mA output current and achieves 0.005% THD+N at 1 kHz with 8 VPP into 10 kΩ (VDD = 12 V). When driving 600 Ω, its high slew rate (+16 V/µs) and low output impedance (0.25 Ω) maintain fidelity up to 100 kHz, meeting professional audio line driver specs.
