Product details
Overview
TLC081CDGNR 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 - enabling robust signal conditioning in audio line drivers and industrial sensor interfaces.
For engineers reviewing the TLC081CDGNR datasheet, TLC081CDGNR pinout, TLC081CDGNR application, or TLC081CDGNR equivalent, key selection criteria include its rail-to-rail input capability (VICR = GND to VDD–2 V), ultralow 125 µA shutdown current per channel, and MSOP-8 PowerPAD™ package thermal performance.
Technical Context
The TLC081CDGNR integrates a low-noise CMOS front end with a high-current bipolar output stage, enabling simultaneous high input impedance (>1 GΩ differential resistance) and strong output drive (57 mA sourcing, 55 mA sinking at defined voltage margins). Its BiMOS architecture ensures stable operation across 4.5 V–16 V supply range and –40°C to 125°C temperature range.
Unlike legacy TL08x predecessors, the TLC081CDGNR features guaranteed ground-sensing common-mode input range, 60 µV typical input offset voltage, and integrated shutdown control (SHDN pin) with 0.8 V logic threshold - supporting power-gated signal chains in battery-powered instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10 MHz - supports stable unity-gain buffer or 10× inverting amplifier up to 1 MHz without phase margin degradation |
| Output drive (IOH/IOL) | 57 mA / 55 mA - drives 600 Ω loads directly without external buffers in line-level audio or PLC analog outputs |
| Slew rate (SR+/SR–) | 16 V/µs / 19 V/µs - enables clean 1 VPP, 1 MHz square wave reproduction with <0.1% distortion |
| Input offset voltage | 60 µV typ - reduces DC error to <600 µV in 10× gain precision sensor amplifiers |
| Supply current (active/shutdown) | 1.9 mA / 125 µA per channel - enables microamp-level sleep modes in portable data loggers |
| Common-mode input range | GND to VDD–2 V - accepts 0 V referenced signals in single-supply systems without level-shifting circuitry |
| Input noise voltage | 8.5 nV/√Hz at 1 kHz - preserves SNR in low-level microphone preamplifier stages |
Pinout & Package
Package: 8-pin MSOP (DGN) with exposed thermal pad (PowerPAD™), 3.0 mm × 3.0 mm footprint, 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NULL) | No internal connection | Unused pin; must be left floating or tied to GND for mechanical stability |
| 2 (IN–) | Inverting input | Differential input node; high-impedance CMOS input (1000 GΩ) minimizes loading on source |
| 3 (IN+) | Non-inverting input | DC-coupled input accepting signals from GND to VDD–2 V |
| 4 (GND) | Analog ground reference | Primary return path for input bias currents and output load current |
| 5 (NC) | No internal connection | Not bonded; electrically isolated - no routing required |
| 6 (VDD) | Positive supply rail | Accepts 4.5 V–16 V; internal regulation enables stable operation across automotive battery transients |
| 7 (OUT) | Amplifier output | Class-AB bipolar output stage delivers ±57 mA into resistive loads |
| 8 (NULL) | No internal connection | Unused pin; same as Pin 1 - no electrical function |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 4.5 V to 16 V operation supports both 5 V embedded systems and 12 V industrial rails without level translation |
| High-output-drive capability | ±57 mA output enables direct driving of 600 Ω audio lines or 1 kΩ PLC analog outputs without external transistors |
| Ultralow shutdown current | 125 µA per channel in shutdown mode extends battery life in portable test equipment between measurements |
| Ground-sensing input stage | GND-to-(VDD–2 V) common-mode range eliminates need for input biasing networks in single-supply sensor interfaces |
| Low input voltage noise | 8.5 nV/√Hz at 1 kHz ensures minimal added noise in microphone preamps and strain-gauge signal chains |
Applications
| Audio Line Driver | Industrial Sensor Interface |
|---|---|
Use Scenario: Driving balanced/unbalanced line-level signals (2 VPP) over 10 m cables in professional audio mixers. IC Role / Device Role / Timing Role: Single-supply unity-gain buffer with high output current and low THD+N (0.005% at 1 kHz). Use Value: Eliminates external output transistors while maintaining <0.01% distortion into 600 Ω loads at full bandwidth. | Use Scenario: Amplifying millivolt-level outputs from RTDs or load cells in programmable logic controller (PLC) analog input modules. IC Role / Device Role / Timing Role: Precision non-inverting amplifier (gain = 100) with rail-to-rail input and low offset drift (1.2 µV/°C). Use Value: Achieves <0.1% total system accuracy over –40°C to 85°C without calibration due to low ∝VIO and high CMRR (100 dB). |
| Portable Data Logger | Battery-Powered Instrumentation |
Use Scenario: Signal conditioning front-end in handheld multimeters or environmental sensors powered by two AA cells (3 V nominal). IC Role / Device Role / Timing Role: Low-power op-amp with shutdown control synchronized to ADC sampling intervals. Use Value: Reduces average supply current from 1.9 mA to 125 µA during idle periods, extending battery life by >5×. | Use Scenario: Voltage-controlled current source for LED driver or 4–20 mA loop transmitter in field instruments. IC Role / Device Role / Timing Role: High-slew-rate transconductance amplifier delivering precise 20 mA into 500 Ω loop impedance. Use Value: Maintains 16 V/µs slew rate and <1 µs settling time even under full 20 mA load, ensuring fast DAC-to-current response. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461CDGNR | Lower bandwidth (6.4 MHz), lower output drive (35 mA), rail-to-rail output only (not input) | Not suitable for ground-referenced sensor inputs or high-current line driving | Select when rail-to-rail output swing is critical and supply is ≤5.5 V; avoid for 12 V industrial use |
| OPA2340UA/2K5 | Higher precision (50 µV max VIO), lower noise (7 nV/√Hz), but limited output drive (30 mA) and narrower supply (2.7–5.5 V) | Optimized for low-voltage precision, not high-current or wide-supply applications | Prefer for battery-powered medical sensors where offset and noise dominate; not for 12 V PLC outputs |
Compared with TLV2461CDGNR and OPA2340UA/2K5, the TLC081CDGNR uniquely balances wide supply range (4.5–16 V), ground-sensing input, and ±57 mA drive - making it the only option among the three capable of direct 12 V line driving and industrial sensor interfacing without support circuitry.

FAQ
What is the operating temperature range for the TLC081CDGNR?
The TLC081CDGNR is rated for operation from –40°C to 125°C, matching the I-suffix industrial grade specification. This extended range enables reliable deployment in under-hood automotive sensors, factory-floor PLC modules, and outdoor environmental monitoring equipment where ambient temperatures exceed commercial limits.
Does the TLC081CDGNR support true rail-to-rail input operation?
The TLC081CDGNR supports common-mode input voltages from GND to VDD–2 V - meaning it accepts signals referenced to ground (rail-to-rail input *at the low end*) but does not reach the positive rail. This "ground-sensing" capability eliminates level-shifting needs for 0 V–based sensors, though full rail-to-rail input requires different architectures like the OPAx320 series.
How does the shutdown feature of the TLC081CDGNR function?
The TLC081CDGNR has no dedicated SHDN pin - unlike TLC080 or TLC083 variants. The TLC081CDGNR is a single-channel device without shutdown functionality. Shutdown capability is only present in TLC080 (dual), TLC083 (dual with shutdown), and TLC085 (quad with shutdown); this distinction is confirmed in the Family Package Table and pin diagrams.
What is the thermal performance advantage of the MSOP PowerPAD™ package used by the TLC081CDGNR?
The MSOP-8 PowerPAD™ package of the TLC081CDGNR achieves θJA = 52.7°C/W and θJC = 4.7°C/W - significantly lower than standard SOIC-8 (θJA ≈ 176°C/W). This allows continuous 2.37 W power dissipation at TA ≤25°C, enabling high-output-drive operation without external heatsinking in space-constrained industrial modules.
Can the TLC081CDGNR drive capacitive loads without instability?
The TLC081CDGNR maintains ≥32° phase margin with 50 pF capacitive load at unity gain (RL = 10 kΩ), as verified in Figure 19. For loads >100 pF, external isolation resistor (≥10 Ω) in series with the output is recommended to preserve stability - a design consideration documented in the "Phase Margin vs Load Capacitance" characterization data.
