Product details
Overview
TLC081AID 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 rail-to-rail input common-mode range (including ground), 60 µV max input offset voltage (A-grade), and ultralow 125 µA/channel shutdown current - enabling high-fidelity audio buffering and industrial sensor signal conditioning in extended temperature environments (–40°C to 125°C).
For engineers reviewing the TLC081AID datasheet, TLC081AID pinout, TLC081AID application, or TLC081AID equivalent, key selection criteria include its guaranteed ground-sensing input stage, high-output-drive capability into heavy loads (e.g., 600 Ω), low 8.5 nV/√Hz input noise, and compatibility with precision single-supply systems requiring fast settling (<0.4 µs at 0.01%) and robust phase margin (≥32°) across capacitive loads.
Technical Context
The TLC081AID employs a BiMOS architecture combining a low-noise CMOS front end with a high-current bipolar output stage, enabling simultaneous high dc precision and ac performance. Its input stage supports full rail-to-rail common-mode operation down to GND, while the output delivers symmetrical sourcing/sinking capability without external level-shifting circuitry.
It integrates an active shutdown control pin (SHDN) that reduces supply current to 125 µA/channel while maintaining fast turn-on (0.47 µs) and turn-off (2.5 µs) times. The device is specified over –40°C to 125°C and exhibits stable operation with load capacitances up to 50 pF and phase margins ≥32° under unity-gain conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10 MHz - enables stable unity-gain buffer or gain-of-10 amplification up to 1 MHz without peaking. |
| Output current (IOH/IOL) | ±57 mA / ±55 mA - drives 600 Ω loads directly at ±5 V swing with <0.5 V saturation, eliminating external buffers. |
| Slew rate (SR+/SR–) | 16 V/µs / 19 V/µs - supports clean 1-Vpp, 1-MHz sine wave generation with <0.01% THD+N at 12 V supply. |
| Input offset voltage (VIO) | 60 µV max (A-grade) - ensures ≤0.6 mV error in 10-V full-scale 16-bit DAC output buffers. |
| Supply voltage range | 4.5 V to 16 V - operates from Li-ion battery (3.7 V nominal + headroom) up to industrial 12 V rails without regulation. |
| Shutdown current | 125 µA/channel - reduces system standby power by >93% vs active mode (1.9 mA), critical for battery-powered instrumentation. |
| Input noise voltage | 8.5 nV/√Hz @ 1 kHz - preserves SNR in low-level sensor interfaces (e.g., thermocouple, strain gauge) without added filtering. |
Pinout & Package
Package: 8-pin SOIC (D package), RoHS-compliant, rated for –40°C to 125°C operation. Thermal resistance θJA = 176°C/W; maximum power dissipation = 710 mW at TA ≤ 25°C.
| Pin | 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 - accepts feedback network; high impedance (>1 TΩ) minimizes loading on precision dividers. |
| 3 | IN+ | Non-inverting input - supports rail-to-rail common-mode range (GND to VDD–2 V), enabling direct sensor interfacing. |
| 4 | GND | Analog ground reference - requires low-impedance star connection to minimize PSRR degradation and crosstalk. |
| 5 | NC | No connection - pin 5 is unconnected in TLC081 (unlike TLC080 which uses it for shutdown); must not be bonded. |
| 6 | VDD | Positive supply - accepts 4.5–16 V; bypassing with 0.1 µF ceramic + 10 µF tantalum recommended near pin. |
| 7 | OUT | Amplifier output - capable of ±57 mA drive; layout must minimize trace inductance when driving capacitive loads >100 pF. |
| 8 | NULL | No internal connection - identical to pin 1; electrically isolated, no routing required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Includes GND and extends to VDD–2 V - eliminates level-shifting for single-supply microcontroller ADC inputs. |
| High-output-drive bipolar stage | Delivers ±57 mA into 600 Ω at 12 V - replaces discrete emitter-follower stages in audio line drivers and actuator interfaces. |
| Low-input-noise CMOS front end | 8.5 nV/√Hz @ 1 kHz - maintains dynamic range in 24-bit delta-sigma ADC front ends without gain-stage noise penalty. |
| Guaranteed A-grade offset voltage | ≤60 µV max at 25°C - reduces calibration overhead in precision weigh scales and medical sensor signal chains. |
| Fast shutdown enable/disable | Turnon time = 0.47 µs, turnoff = 2.5 µs - enables burst-mode operation in portable data loggers with microsecond-level power gating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA350UA | Lower noise (7 nV/√Hz), lower GBW (38 MHz), no shutdown pin, SOIC-8 package | Lacks shutdown control; higher bandwidth suits RF IF stages but overkill for DC–1 MHz sensor apps | Choose when ultra-low noise dominates over power gating; verify stability with capacitive loads. |
| TLV2461CDR | Lower drive (±15 mA), lower supply current (550 µA), rail-to-rail output only, same SOIC-8 footprint | Insufficient output current for 600 Ω loads; better for low-power, low-voltage (2.7 V) designs | Select for cost-sensitive, low-power systems where ±57 mA drive is unnecessary. |
Compared with OPA350UA and TLV2461CDR, the TLC081AID uniquely balances high output drive, guaranteed A-grade offset, and integrated shutdown in a standard SOIC-8 - making it optimal for industrial and audio applications demanding both precision and robust load handling without layout changes.

FAQ
What is the maximum load capacitance the TLC081AID can drive stably?
The TLC081AID maintains ≥32° phase margin with up to 50 pF capacitive load at unity gain (RL = 10 kΩ, CL = 50 pF). For loads >50 pF, external isolation resistor (e.g., 10–50 Ω in series with output) is recommended to prevent peaking or oscillation, as confirmed in Figure 19 of the SLOS254F datasheet.
Does the TLC081AID have a shutdown pin, and how is it controlled?
No - the TLC081AID does not include a shutdown pin. Unlike the TLC080 (which has SHDN on pin 5), the TLC081 uses pin 5 as NC (no connection). Shutdown functionality is absent in this variant; only TLC080, TLC083, and TLC085 offer active shutdown per the FAMILY PACKAGE TABLE in the datasheet.
What is the input common-mode voltage range for the TLC081AID at 5 V supply?
At VDD = 5 V, the TLC081AID supports a common-mode input range from GND (0 V) to VDD–2 V (3 V), as specified in the RECOMMENDED OPERATING CONDITIONS table. This rail-to-ground capability enables direct interfacing with zero-referenced sensors and microcontroller I/O without level-shifting circuitry.
How does the TLC081AID's output drive compare to standard rail-to-rail op-amps?
The TLC081AID delivers ±57 mA sourcing/sinking current - significantly higher than typical rail-to-rail op-amps (e.g., TLV2461: ±15 mA). This enables direct driving of low-impedance loads like 600 Ω audio lines or relay coils without external buffers, reducing BOM count and PCB area while maintaining <0.5 V saturation voltage.
Is the TLC081AID pin-compatible with the TLC080 or TL081?
The TLC081AID is pin-compatible with the TLC080 in SOIC-8 (D) package regarding pin 1–4 and 6–8, but differs critically at pin 5: TLC080 uses pin 5 for SHDN, while TLC081 leaves it NC. It is not pin-compatible with TL081 (JFET-input, no rail-to-rail input, different offset specs) due to incompatible input stage architecture and performance envelope.
