Product details
Overview
TLC080CP 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 supply - enabling robust signal conditioning in audio line drivers and industrial sensor interfaces.
For engineers reviewing the TLC080CP datasheet, TLC080CP pinout, TLC080CP application, or TLC080CP equivalent, key selection criteria include its shutdown capability, rail-to-rail input common-mode range (GND to VDD–2 V), ultralow 125 µA shutdown current per channel, and compatibility with 8-pin PDIP packaging for through-hole prototyping and legacy industrial designs.
Technical Context
The TLC080CP integrates a low-noise CMOS front end with a high-current bipolar output stage in TI's LBC3 BiCMOS process, enabling simultaneous high input impedance (>1 GΩ differential) and strong output drive (±55 mA min). Its internal offset nulling pins support precision DC-coupled configurations without external trimming networks.
It features active shutdown control (SHDN pin), allowing rapid power gating with 0.15 µs turn-on and 1.3 µs turn-off times. The device maintains stable operation across 0°C to 70°C (C-suffix) with guaranteed VICR from ground and 130 dB supply rejection at DC - critical for noisy single-rail systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10 MHz - supports stable unity-gain buffers up to 10 MHz or closed-loop gains of 10 at 1 MHz. |
| Output drive (IOH/IOL) | ±57 mA / ±55 mA - drives 600 Ω loads directly without external boost stages. |
| Slew rate (SR+/SR−) | 16 V/µs / 19 V/µs - enables fast settling for pulse and video signals with minimal distortion. |
| Input offset voltage | 60 µV typical - ensures <1 mV total error in precision DC amplification at room temperature. |
| Supply current (active/shutdown) | 1.9 mA / 125 µA per channel - reduces system power by >93% during idle periods. |
| Common-mode input range | GND to VDD–2 V - accepts signals down to ground in single-supply configurations. |

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 (4 MHz), no shutdown, higher input offset (3 mV max), BiFET architecture. | Lacks shutdown and high-output-drive capability; unsuitable for battery-powered or heavy-load applications. | Choose TL081CP only if cost sensitivity outweighs performance requirements and shutdown is unnecessary. |
| OPA2340PA | Rail-to-rail output, lower supply current (800 µA), no shutdown, CMOS input (1 pA IIB), 5.5 MHz GBW. | Better for ultra-low-power, low-voltage (2.7–5 V) designs but cannot drive 600 Ω loads or operate above 5.5 V. | Select OPA2340PA when rail-to-rail output swing and femtoampere input bias are required at the expense of bandwidth and output drive. |
Compared with TL081CP and OPA2340PA, the TLC080CP uniquely combines 10 MHz bandwidth, ±55 mA output drive, and active shutdown in an 8-pin PDIP package - making it the only option among the three that supports high-fidelity audio line driving and industrial sensor conditioning on a single 12 V rail with power-gating capability.

FAQ
What is the operating temperature range for the TLC080CP?
The TLC080CP is rated for 0°C to 70°C (commercial temperature range), as indicated by the "C" suffix in the part number. This makes it suitable for indoor industrial controls, consumer audio equipment, and laboratory instrumentation where ambient temperatures remain within this range. The device meets all electrical specifications across this full interval without derating.
Does the TLC080CP support rail-to-rail input or output?
The TLC080CP supports rail-to-rail input common-mode range (GND to VDD–2 V) but does not provide rail-to-rail output swing. Its output typically swings to within ~1.5 V of VDD and ~0.5 V above GND under 55 mA load. For true rail-to-rail output, consider alternatives like the OPA2340PA - though those lack the TLC080CP's bandwidth and output drive.
How is the shutdown function implemented on the TLC080CP?
The TLC080CP uses an active-low SHDN pin (Pin 5) that places the amplifier in ultralow-power mode when pulled ≤0.8 V. In shutdown, supply current drops to 125 µA per channel, output becomes high-impedance, and turnoff time is 1.3 µs. A pull-up resistor to VDD ensures normal operation when no external control is applied.
Can the TLC080CP drive a 600 Ω load effectively?
Yes - the TLC080CP is specifically characterized to deliver ±55 mA continuous output current, enabling direct driving of 600 Ω loads at ±5 V output swing with minimal distortion (THD+N = 0.005% at 1 kHz). This eliminates the need for external emitter-follower buffers in professional audio line driver applications.
What is the purpose of Pins 1 and 8 on the TLC080CP?
Pins 1 and 8 are offset null terminals used to connect an external 10 kΩ potentiometer for trimming input offset voltage to near-zero. This feature enables precision DC-coupled applications such as strain gauge amplifiers or precision integrators where sub-millivolt accuracy is required over temperature and time.
