Product details
Overview
TLC081IP 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 - enabling robust signal conditioning in audio line drivers and industrial sensor interfaces.
For engineers reviewing the TLC081IP datasheet, TLC081IP pinout, TLC081IP application, or TLC081IP 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 8-pin PDIP package compatibility with legacy through-hole layouts.
Technical Context
The TLC081IP integrates a low-noise CMOS front end with a high-current bipolar output stage in TI's LBC3 BiCMOS process, enabling both high impedance (>1 TΩ differential input resistance) and strong drive capability. Its architecture supports stable unity-gain operation with phase margin ≥32° at CL = 50 pF and RL = 10 kΩ.
Unlike TL08x predecessors, it ensures ground-sensing common-mode input range and features dedicated shutdown control (SHDN pin) with logic-level thresholds (VIH = 2 V, VIL = 0.8 V), allowing precise power sequencing in battery-powered systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - supports audio and medium-speed signal conditioning up to ~1.6 MHz closed-loop with gain of 6. |
| Output Drive | ±57 mA - drives heavy loads like 600 Ω audio lines or capacitive DAC buffers without external boost. |
| Slew Rate | +16 V/µs / –19 V/µs - enables fast settling for pulse amplification and active filter stages. |
| Supply Range | 4.5 V to 16 V - compatible with 5 V, 12 V, and dual-rail-derived single supplies. |
| Input Offset | 60 µV typical - reduces DC error in precision transimpedance or instrumentation amplifier front ends. |
| Shutdown Current | 125 µA/channel - cuts quiescent power by >93% versus active mode (1.9 mA), critical for portable devices. |
| Input Noise | 8.5 nV/√Hz at 1 kHz - suitable for low-level sensor signal amplification without dominant noise contribution. |
Pinout & Package
Package: 8-pin plastic DIP (P package), through-hole mount, 0.3-inch width, RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NULL | No internal connection - unused pin; leave unconnected or tie to GND for mechanical stability. |
| 2 | IN– | Inverting input - accepts feedback network for inverting configurations or reference voltage in non-inverting setups. |
| 3 | IN+ | Non-inverting input - high-impedance node (1000 GΩ) for sensor or reference signal routing. |
| 4 | GND | Analog ground reference - must be low-impedance path to system ground plane; separates analog return from digital. |
| 5 | NC | No connection - pin 5 is unassigned in TLC081 (distinct from TLC080 which uses it for SHDN). |
| 6 | VDD | Positive supply - accepts 4.5–16 V; bypass with 0.1 µF ceramic capacitor near pin for stability. |
| 7 | OUT | Amplifier output - capable of sourcing/sinking ±57 mA into resistive or moderate capacitive loads. |
| 8 | NULL | No internal connection - unused pin; same handling as Pin 1. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS input stage (ultralow IB, 100 pA typ) with bipolar output (high IOUT, low Zo = 0.25 Ω), eliminating trade-offs between speed and drive. |
| Ground-Sensing Input Range | VICR extends to GND - enables direct interfacing with 0 V-referenced sensors (e.g., thermocouples, bridge outputs) without level-shifting circuitry. |
| Logic-Compatible Shutdown | SHDN pin absent on TLC081IP - unlike TLC080, this variant lacks shutdown functionality, simplifying control logic in always-on applications. |
| Stable Unity-Gain Operation | Phase margin ≥32° with 50 pF load - eliminates need for external compensation in most buffer and follower designs. |
| Low Distortion at High Load | THD+N = 0.005% at 1 kHz, 8 VPP into 10 kΩ - preserves fidelity in audio line drivers and precision waveform generation. |
Applications
| Audio Line Driver | Industrial Sensor Interface |
|---|---|
Use Scenario: Driving balanced/unbalanced 600 Ω audio lines from microcontroller DAC outputs in broadcast equipment. IC Role / Device Role / Timing Role: Single-supply voltage follower with high output current and low THD+N to preserve signal integrity over long cables. Use Value: Delivers ±57 mA into 600 Ω while maintaining <0.01% distortion - avoids external emitter-follower stages and reduces BOM count. | Use Scenario: Amplifying low-level mV-range signals from strain gauges or RTDs in PLC analog input modules. IC Role / Device Role / Timing Role: Precision non-inverting amplifier with rail-to-rail input (GND to VDD–2 V) and 60 µV offset for minimal DC error. Use Value: Enables direct connection to grounded sensors without biasing networks - improves measurement accuracy and simplifies PCB layout. |
| Active Filter Stage | High-Speed Comparator Buffer |
Use Scenario: Implementing 2nd-order Sallen-Key low-pass filters in medical ECG front ends requiring >100 dB CMRR. IC Role / Device Role / Timing Role: Gain stage with 10 MHz GBW and 8.5 nV/√Hz input noise to maintain SNR in multi-stage filtering. Use Value: Provides sufficient bandwidth and low noise to support 1 kHz cutoff filters with <0.1 dB passband ripple - no performance compromise vs. discrete op-amp alternatives. | Use Scenario: Buffering comparator outputs (e.g., LM393) driving 50 Ω transmission lines or ADC sample-and-hold inputs. IC Role / Device Role / Timing Role: Fast-settling unity-gain buffer (ts = 0.17 µs @ 0.01%) isolating sensitive comparator outputs from capacitive loads. Use Value: Prevents comparator oscillation and timing skew caused by back-driving - ensures clean, jitter-free sampling clock edges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL081CP | Lower bandwidth (3 MHz), higher input offset (3 mV max), no guaranteed ground-sensing VICR. | Limited to lower-frequency, less precision-critical designs; requires input biasing for GND-referenced sources. | Select when cost sensitivity outweighs bandwidth and DC precision requirements. |
| OPA2340PA | Rail-to-rail input/output, lower noise (7 nV/√Hz), but lower output drive (30 mA) and narrower supply range (2.7–5.5 V). | Better suited for low-voltage portable systems; insufficient for 12 V line drivers or high-current loads. | Choose for battery-powered instrumentation where rail-to-rail swing and ultra-low voltage operation are mandatory. |
Compared with TL081CP and OPA2340PA, the TLC081IP uniquely balances 10 MHz bandwidth, ±57 mA drive, and ground-sensing input in a legacy-compatible PDIP package - making it optimal for industrial and audio upgrades where performance and pinout compatibility are jointly required.

FAQ
What is the operating temperature range for the TLC081IP?
The TLC081IP is rated for operation from –40°C to +125°C (I-suffix grade), making it suitable for under-hood automotive, industrial control, and outdoor equipment applications where ambient temperatures exceed commercial limits. This extended range is confirmed in the "Recommended Operating Conditions" table of the official SLOS254F datasheet.
Does the TLC081IP include a shutdown pin?
No, the TLC081IP does not feature a shutdown pin. Unlike the TLC080 (which has SHDN on Pin 5), the TLC081IP uses Pin 5 as NC (no connection). The datasheet explicitly states "TLC081 - Refer to the EVM Selection Guide" under shutdown capability, confirming absence of shutdown functionality in this variant.
What is the maximum output current capability of the TLC081IP?
The TLC081IP delivers ±57 mA continuous output current - 57 mA sourced (IOH) at VDD – 1.5 V and 55 mA sunk (IOL) at 0.5 V - verified across the full temperature range. This is specified in the "Features" section and confirmed in Electrical Characteristics tables for both 5 V and 12 V supply conditions.
Can the TLC081IP operate with a single 5 V supply?
Yes, the TLC081IP is fully specified for single-supply operation down to 4.5 V. At VDD = 5 V, it maintains 10 MHz gain-bandwidth, 16 V/µs slew rate, and ground-sensing input range (VICR = GND to 3.0 V), enabling direct use with 5 V microcontrollers and ADCs without level-shifting circuitry.
How does the input offset voltage of the TLC081IP compare to the TL081?
The TLC081IP has a typical input offset voltage of 60 µV - a 50× improvement over the TL081's typical 3 mV (3000 µV). This is documented in the "Electrical Characteristics" table and reflects the BiMOS process advantage, directly reducing DC error in precision amplification stages using the TLC081IP.
