Product details
Overview
TLC081CP 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 TLC081CP datasheet, TLC081CP pinout, TLC081CP application, or TLC081CP 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 confirmed 8-pin PDIP package compatibility with legacy TL081 layouts.
Technical Context
The TLC081CP integrates a low-noise CMOS front end with a high-current bipolar output stage in TI's LBC3 BiCMOS process, enabling simultaneous high impedance (>1 TΩ differential input resistance), low input noise (8.5 nV/√Hz at 1 kHz), and strong capacitive load driving (up to 50 pF with stable phase margin).
It features internally compensated unity-gain stability, no external compensation required, and supports true single-supply operation with common-mode input range extending to ground - eliminating level-shifting circuitry in microcontroller-based analog front ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - enables accurate amplification of signals up to audio band and beyond without gain roll-off. |
| Output Drive | ±57 mA - drives heavy loads like 600 Ω audio lines or multiple logic inputs directly. |
| Slew Rate | +16 V/µs / –19 V/µs - preserves fast transient fidelity in pulse and video applications. |
| Supply Range | 4.5 V to 16 V - compatible with 5 V, 12 V, and battery-powered systems without regulation. |
| Input Offset Voltage | 60 µV typical - reduces DC error in precision gain stages and sensor amplifiers. |
| Shutdown Current | 125 µA per channel - enables low-power sleep modes in portable instrumentation. |
| Input Noise | 8.5 nV/√Hz at 1 kHz - supports clean amplification of low-level transducer signals. |
Pinout & Package
Package: 8-pin plastic DIP (PDIP), through-hole mount, 0°C to 70°C operating temperature range (C-suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NULL | No internal connection - left unconnected or grounded per layout best practice. |
| 2 | IN– | Inverting input - accepts feedback network for stable closed-loop configurations. |
| 3 | IN+ | Non-inverting input - connects to reference or sensor signal in follower or summing topologies. |
| 4 | GND | Analog ground reference - must be tied to system ground plane with low-impedance path. |
| 5 | NC | No connection - not bonded; electrically isolated from die. |
| 6 | VDD | Positive supply rail - requires local 0.1 µF ceramic decoupling capacitor. |
| 7 | OUT | Amplified output - capable of sourcing/sinking ±57 mA into resistive or capacitive loads. |
| 8 | NULL | No internal connection - unused pin; no routing required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends to GND and up to VDD–2 V - eliminates need for input biasing in single-supply designs. |
| High-output current capability | ±57 mA sourcing/sinking - drives low-impedance loads without external buffers. |
| Ultralow shutdown quiescent current | 125 µA per channel - enables power-gating in battery-operated data loggers. |
| Low input voltage noise density | 8.5 nV/√Hz at 1 kHz - preserves SNR in microphone preamps and strain gauge amplifiers. |
| Stable with capacitive loads | Phase margin ≥32° with 50 pF load - avoids oscillation when driving ADC input filters or cables. |

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 shutdown mode, 1.4 mA supply current. | Lacks single-supply rail-to-rail input support and high-output drive - unsuitable for 5 V-only systems or low-Z loads. | Select TLC081CP when upgrading from TL081CP for improved speed, precision, and power efficiency in new designs. |
| OPA2340PA | Rail-to-rail I/O, lower noise (7 nV/√Hz), but limited output drive (30 mA), narrower supply range (2.7–5.5 V). | Optimized for low-voltage portable gear; cannot replace TLC081CP in 12 V industrial or audio line-driving roles. | Choose OPA2340PA only for sub-5 V battery-powered applications where rail-to-rail output is mandatory. |
Compared with TL081CP and OPA2340PA, the TLC081CP uniquely balances 10 MHz bandwidth, ±57 mA drive, and 4.5–16 V operation - making it the only drop-in upgrade for legacy TL081 designs requiring higher performance without changing supply architecture or PCB layout.

FAQ
What is the maximum supply voltage rating for the TLC081CP?
The TLC081CP has an absolute maximum supply voltage of 17 V, with recommended operation from 4.5 V to 16 V. Exceeding 17 V risks permanent damage. At 16 V, it maintains full specified performance including ±57 mA output drive and 10 MHz bandwidth - making it suitable for 12 V industrial rails with headroom for transients.
Does the TLC081CP support true single-supply operation with input signals at ground potential?
Yes, the TLC081CP supports true single-supply operation: its common-mode input voltage range extends to GND (0 V) and up to VDD–2 V. This allows direct connection of sensors or microcontroller outputs referenced to ground without level-shifting circuitry - a key differentiator from older TL081CP devices.
What is the shutdown functionality of the TLC081CP, and how is it controlled?
The TLC081CP does not include a shutdown pin. Shutdown capability is present only in the TLC080 (pin 5), TLC083, and TLC085 variants. The TLC081CP is a fixed-function single op-amp with no enable/disable control - its supply current remains at 1.9 mA per channel under all operating conditions.
Can the TLC081CP drive a 600 Ω load at full output swing without distortion?
Yes, the TLC081CP delivers ±57 mA output current and achieves <0.005% THD+N at 1 kHz into 600 Ω with 8 VPP output when supplied at 12 V. Its high slew rate (+16 V/µs) and stable phase margin ensure clean large-signal response - meeting professional audio line driver requirements per AES3 standards.
Is the TLC081CP pin-compatible with the TL081CP for drop-in replacement?
Yes, the TLC081CP uses the same 8-pin PDIP package and identical pinout as the TL081CP (including NULL, IN–, IN+, GND, NC, VDD, OUT, NULL). No PCB changes are required - but designers must verify that the improved bandwidth, lower offset, and rail-to-rail input behavior align with system timing and accuracy requirements.
