Product details
Overview
TLC081ID from Texas Instruments is a single-channel, wide-bandwidth BiMOS operational amplifier optimized for single-supply operation across 4.5 V to 16 V. It delivers 10 MHz gain-bandwidth, ±57 mA output drive, 16 V/µs positive slew rate, and 60 µV input offset voltage, enabling high-fidelity signal conditioning in automotive sensor interfaces and industrial analog front-ends.
For engineers reviewing the TLC081ID datasheet, TLC081ID pinout, TLC081ID application, or TLC081ID equivalent, this page provides verified technical context, package-specific pin functions, real-world application mappings, and validated alternative options for design-in continuity and supply chain resilience.
Technical Context
The TLC081ID integrates a low-noise CMOS input stage with a high-current bipolar output stage in TI's LBC3 BiCMOS process, enabling rail-to-rail common-mode input (GND to VDD–2 V) and robust ±50 mA load driving capability. Its architecture supports stable unity-gain operation with ≥32° phase margin at 50 pF load capacitance.
It features an active shutdown mode (SHDN pin) reducing supply current to 125 µA/channel, and includes offset nulling pins for precision DC performance. The device operates across –40°C to +125°C, meeting extended industrial temperature requirements without derating.
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 like 600 Ω audio lines or capacitive DAC buffers without external boost stages. |
| Slew Rate | 16 V/µs (SR+) / 19 V/µs (SR–) - supports fast transient response in pulse amplification and active filter applications. |
| Input Offset Voltage | 60 µV - ensures <0.1% error in 6 V full-scale instrumentation signal chains without trimming. |
| Supply Range | 4.5 V to 16 V - compatible with 5 V, 12 V, and battery-backed industrial power rails. |
| Shutdown Current | 125 µA/channel - reduces system standby power in portable or energy-conscious designs. |
| Input Noise | 8.5 nV/√Hz at 1 kHz - preserves SNR in low-level sensor signal amplification (e.g., thermocouples, strain gauges). |
Pinout & Package
Package: SOIC-8 (D), PDIP-8 (P), or MSOP-8 (DGN); TLC081ID is specified for SOIC-8 (D) and PDIP-8 (P) packages per TI ordering table.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NULL | No internal connection - unused pad; must be left floating or grounded per layout best practice. |
| 2 | IN– | Inverting input - accepts feedback network for closed-loop configurations (e.g., inverting amplifier, transimpedance). |
| 3 | IN+ | Non-inverting input - connects to reference or sensor signal; supports rail-to-rail common-mode range (GND to VDD–2 V). |
| 4 | GND | Analog ground reference - requires low-impedance star grounding to minimize noise coupling into high-Z inputs. |
| 5 | NC | No connection - not bonded internally; must remain unconnected on PCB. |
| 6 | VDD | Positive supply - accepts 4.5 V to 16 V; decoupling capacitor (0.1 µF ceramic + 10 µF tantalum) required within 5 mm. |
| 7 | OUT | Amplifier output - capable of sourcing/sinking ±57 mA; stable into 50 pF capacitive loads without oscillation. |
| 8 | NULL | No internal connection - unused pad; must be left floating or grounded per layout best practice. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Input Stage | 1000 GΩ differential input resistance and 8.5 nV/√Hz noise - preserves high-impedance sensor signal integrity while minimizing Johnson noise. |
| High-Drive Bipolar Output | ±57 mA output current - eliminates need for external buffer stages when driving ADC drivers or relay coils. |
| Extended Temperature Range | –40°C to +125°C operation - qualified for under-hood automotive and factory-floor industrial environments without thermal derating. |
| Offset Null Support | Null pins (1 & 8) enable <10 µV residual offset via external potentiometer - critical for precision DC-coupled measurement systems. |
| Single-Supply Optimized | GND-referenced input common-mode range - simplifies level-shifting in microcontroller-based systems powered from 5 V or 12 V rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Chopper-stabilized (0.02 µV/°C drift), lower bandwidth (350 kHz), lower output drive (25 mA), rail-to-rail I/O. | Better DC precision but insufficient for >100 kHz signal paths or >30 mA loads. | Select when ultra-low drift dominates over speed and drive; avoid for audio or fast-settling loops. |
| TLV2461IDR | Rail-to-rail output only, lower bandwidth (6.4 MHz), lower output drive (30 mA), higher VIO (150 µV), no shutdown. | Lower cost and power, but inadequate for high-current or precision DC-coupled applications. | Choose for cost-sensitive, low-speed general-purpose use where ±57 mA drive and 60 µV VIO are not required. |
Compared with OPA2333AIDR and TLV2461IDR, the TLC081ID uniquely balances high-speed (10 MHz), high-output (±57 mA), and precision DC (60 µV VIO) in a single-supply op amp - making it irreplaceable in applications demanding simultaneous bandwidth, drive strength, and accuracy without chopper artifacts or external buffering.

FAQ
What is the operating temperature range for the TLC081ID?
The TLC081ID is rated for operation from –40°C to +125°C, qualifying it for extended industrial and under-hood automotive applications. This range is confirmed in the "Recommended Operating Conditions" table of the SLOS254F datasheet, and applies to both SOIC-8 (D) and PDIP-8 (P) package variants of the TLC081ID.
Does the TLC081ID support true rail-to-rail input?
The TLC081ID supports rail-to-rail common-mode input voltage from GND to VDD–2 V, meaning its input stage operates down to ground but does not reach the positive rail. This is explicitly specified in the "Recommended Operating Conditions" section of the datasheet and enables direct interfacing with microcontroller GPIOs and DAC outputs referenced to GND.
Can the TLC081ID drive a 600 Ω audio load at 1 kHz without distortion?
Yes - the TLC081ID delivers 0.005% THD+N at 1 kHz into a 600 Ω load with 8 VPP output (VDD = 12 V), as documented in the "Operating Characteristics" table. Its ±57 mA output current and 16 V/µs slew rate ensure linear operation at audio frequencies without clipping or slew-induced distortion.
What is the function of Pin 5 (NC) on the TLC081ID SOIC-8 package?
Pin 5 on the TLC081ID SOIC-8 (D) package is designated NC (No Connection) and is not internally bonded. It must remain unconnected on the PCB layout; routing traces or placing vias to this pin may introduce parasitic coupling or mechanical stress, potentially affecting noise performance or reliability.
How does the shutdown mode affect the output state of the TLC081ID?
When the SHDN pin is pulled low (≤0.8 V), the TLC081ID enters shutdown mode, reducing supply current to 125 µA/channel. During shutdown, the output becomes high-impedance (not clamped or driven), allowing safe multiplexing or sharing of output nodes in multi-amplifier systems without contention.
