Product details
Overview
TLC081CD 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 supply - enabling precision signal conditioning in audio line drivers and industrial sensor interfaces.
For engineers reviewing the TLC081CD datasheet, TLC081CD pinout, TLC081CD application, or TLC081CD equivalent, key selection criteria include its rail-to-rail input common-mode range (GND to VDD–2 V), ultralow 125 µA shutdown current per channel, and MSOP-8/SOIC-8 package compatibility for space-constrained analog front-ends.
Technical Context
The TLC081CD integrates a low-noise CMOS input stage with a high-current bipolar output stage in TI's LBC3 BiCMOS process, enabling both high impedance (>1 GΩ differential input resistance) and robust load driving (±55 mA sinking/sourcing). Its architecture supports stable unity-gain operation with ≥32° phase margin at 50 pF load capacitance.
Unlike legacy TL08x predecessors, the TLC081CD ensures ground-sensing input common-mode range and achieves 60 µV typical input offset voltage - critical for DC-coupled instrumentation amplifiers and single-supply transimpedance stages where offset error directly impacts measurement accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10 MHz - enables stable closed-loop operation up to 100 kHz with gain of 100, suitable for anti-aliasing filters and active low-pass stages. |
| Output drive current | ±57 mA - drives 600 Ω loads directly without external buffers, reducing BOM count in audio line outputs and motor control feedback paths. |
| Slew rate (SR+) | 16 V/µs - supports fast transient response in pulse amplification and DAC output buffering with <0.39 µs settling to 0.01% for 1 V step. |
| Input offset voltage | 60 µV typical - minimizes DC error in precision current sensing and thermocouple amplification where sub-100 µV offset is required. |
| Supply current (active) | 1.9 mA per channel - balances speed and power efficiency for battery-powered data loggers and portable medical sensors. |
| Shutdown current | 125 µA per channel - enables low-power sleep modes in always-on monitoring systems without sacrificing wake-up performance. |
| Input noise voltage | 8.5 nV/√Hz at 1 kHz - preserves signal integrity in low-level sensor interfaces such as piezoelectric accelerometers and strain gauge bridges. |
Pinout & Package
Package: SOIC-8 (D package), 8-pin small-outline integrated circuit with standard 1.27 mm pitch and 4.9 mm × 3.9 mm footprint - compatible with automated SMT assembly and legacy PCB footprints for TL081 and similar op-amps.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NULL | No internal connection - unused pin; must be left floating or tied to GND for mechanical stability only. |
| 2 | IN− | Inverting input - accepts feedback network or signal source; supports rail-to-rail common-mode input down to GND. |
| 3 | IN+ | Non-inverting input - high-impedance CMOS node (1000 GΩ); used for reference biasing or sensor excitation. |
| 4 | GND | Analog ground reference - shared return path for input signals and output load; requires low-impedance PCB plane. |
| 5 | NC | No connection - not bonded internally; electrically isolated and must remain unconnected. |
| 6 | VDD | Positive supply rail - accepts 4.5 V to 16 V single supply; decoupling capacitor (0.1 µF) required within 5 mm. |
| 7 | OUT | Amplifier output - capable of sourcing/sinking ±57 mA into resistive loads; drives capacitive loads up to 50 pF stably. |
| 8 | NULL | No internal connection - unused pin; identical function to Pin 1 and must be left floating. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Operates with inputs from GND to VDD–2 V - eliminates level-shifting circuits in single-supply data acquisition front-ends. |
| High-output-drive bipolar output stage | Delivers ±57 mA into 600 Ω loads - replaces discrete emitter-follower buffers in audio line drivers and actuator interfaces. |
| Ultralow shutdown current | 125 µA per channel in SHDN mode - extends battery life in portable instrumentation without compromising turn-on time (<0.47 µs). |
| Low input noise voltage | 8.5 nV/√Hz at 1 kHz - maintains SNR >90 dB in 20 kHz bandwidth applications like studio-grade microphone preamplifiers. |
| Stable unity-gain operation | 32° phase margin with 50 pF capacitive load - enables direct connection to ADC input capacitors or long cables without oscillation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL081CD | Lower bandwidth (4 MHz), higher input offset (3 mV max), no shutdown mode, 1.4 mA supply current. | Limited to lower-speed, non-battery applications where power and precision are secondary. | Select TL081CD only when cost sensitivity outweighs performance requirements and existing designs require drop-in replacement without layout change. |
| OPA2340UA | Rail-to-rail I/O, lower noise (7 nV/√Hz), but lower output drive (25 mA), 1.2 mA supply current, no shutdown. | Better for ultra-low-voltage (2.7 V) or rail-to-rail output apps, but insufficient for 600 Ω line driving or high-current feedback loops. | Choose OPA2340UA when output swing to rails is mandatory and load current stays below 25 mA. |
Compared with TL081CD and OPA2340UA, the TLC081CD uniquely combines 10 MHz bandwidth, ±57 mA drive, and 125 µA shutdown - making it the only option among the three that simultaneously meets high-speed, high-current, and low-power requirements in modern single-supply industrial analog designs.

FAQ
What is the maximum supply voltage rating for the TLC081CD?
The TLC081CD has an absolute maximum supply voltage (VDD) rating of 17 V. Operation is specified across a recommended range of 4.5 V to 16 V. Exceeding 17 V risks permanent damage, and operation above 16 V voids guaranteed performance per the datasheet's recommended conditions. The TLC081CD must be used within this envelope to ensure reliability and specification compliance.
Does the TLC081CD support rail-to-rail input operation?
Yes, the TLC081CD supports rail-to-rail input common-mode voltage from GND to VDD–2 V. This allows direct interfacing with ground-referenced sensors and single-supply ADCs without level-shifting circuitry. However, the output is not rail-to-rail - it swings within ~1.5 V of each rail under full load, as confirmed by VOH/VOL specifications at ±50 mA.
How does the shutdown feature of the TLC081CD function?
The TLC081CD does not include a dedicated shutdown pin. Unlike the TLC080 and TLC083 variants, the TLC081CD lacks SHDN functionality - its pin 5 is NC (no connection), and no shutdown mode is specified in the datasheet. Power reduction must be achieved externally via supply gating. This distinguishes TLC081CD from other members of the TLC08x family.
What is the typical input offset voltage for the TLC081CD at room temperature?
The typical input offset voltage for the TLC081CD is 60 µV at 25°C, as specified in the Electrical Characteristics table under VIO parameter. The maximum guaranteed value is 1900 µV for the C-suffix grade across 0°C to 70°C. This 60 µV typical value enables high-precision DC-coupled applications such as strain gauge amplification and thermocouple signal conditioning.
Which packages are available for the TLC081CD?
The TLC081CD is offered in three industry-standard packages: SOIC-8 (D), MSOP-8 (DGN), and PDIP-8 (P). All share identical pinout and electrical specifications. The SOIC-8 is most widely used in automated manufacturing; MSOP-8 provides 30% smaller footprint for space-constrained designs; PDIP-8 supports through-hole prototyping and legacy board upgrades.
