Product details
Overview
TLC080CDR from Texas Instruments is a single-channel, wide-bandwidth BiMOS operational amplifier optimized for single-supply operation (4.5 V to 16 V), delivering 10 MHz gain-bandwidth, ±57 mA output drive, and 16 V/µs positive slew rate. It features shutdown capability, rail-to-rail input common-mode range (including ground), and ultralow 125 µA shutdown current per channel - used in high-fidelity audio buffers, industrial sensor signal conditioning, and active filter stages.
For engineers reviewing the TLC080CDR datasheet, TLC080CDR pinout, TLC080CDR application, or TLC080CDR equivalent, key selection criteria include its 8-pin SOIC package with integrated shutdown control, guaranteed performance across –40°C to 125°C, low 8.5 nV/√Hz input noise, and ability to drive heavy loads without external boost circuitry.
Technical Context
The TLC080CDR implements a BiMOS architecture combining a CMOS front end for high input impedance (>1 GΩ) and low input bias current (<100 pA) with a bipolar output stage enabling high-current sourcing/sinking. Its internal offset nulling pins support precision DC-coupled designs.
It operates in both linear and shutdown modes controlled by the SHDN pin, with fast turnon (0.15 µs) and turnoff (1.3 µs) times. The device maintains stability with capacitive loads up to 50 pF and exhibits 32° phase margin at unity gain with 10 kΩ load and 50 pF capacitance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461CDR | Lower bandwidth (6.4 MHz), lower output drive (±30 mA), no shutdown pin, higher input offset (150 µV typ) | Optimized for low-power, low-voltage (2.7–6 V) applications; lacks high-current drive needed for 600 Ω loads | Select when supply voltage is constrained to <5 V and output load is light (≥10 kΩ) |
| OPA2340UA/2K5 | Higher precision (50 µV VIO max), rail-to-rail output, but lower output current (±20 mA), no shutdown, 5.5 MHz GBW | Better for ultra-low-offset, low-noise instrumentation; insufficient drive for audio line or capacitive loads | Select when DC accuracy dominates over AC performance and load drive capability |
Compared with TLV2461CDR and OPA2340UA/2K5, the TLC080CDR uniquely balances wide bandwidth, high output current, and shutdown functionality in a cost-effective SOIC package - making it optimal for industrial analog front ends where both speed and drive strength are mandatory.

FAQ
What is the operating temperature range for the TLC080CDR?
The TLC080CDR is rated for commercial operation from 0°C to 70°C (C-suffix). Its datasheet specifies absolute maximum ratings up to 150°C junction temperature, but guaranteed performance and parametric specifications apply only within the 0°C to 70°C ambient range. For extended temperature operation, the TLC080IDR variant is specified from –40°C to 125°C.
Does the TLC080CDR require external compensation for stability?
No, the TLC080CDR is unity-gain stable and does not require external compensation components. It maintains ≥32° phase margin with 50 pF capacitive load and 10 kΩ feedback resistance. Stability is verified across supply voltages (4.5 V to 16 V) and temperatures (0°C to 70°C), as confirmed in the datasheet's phase margin vs. load capacitance plots (Figures 19–20).
How does the shutdown feature of the TLC080CDR function electrically?
The TLC080CDR's SHDN pin (Pin 5) is an active-low control input. When pulled ≤0.8 V (VIL), the amplifier enters shutdown mode, reducing supply current to 125 µA per channel. When pulled ≥2 V (VIH), normal operation resumes. Turnon time is 0.15 µs and turnoff time is 1.3 µs, measured from SHDN transition to 50% IDD change - enabling rapid power cycling in responsive systems.
Can the TLC080CDR drive a 600 Ω load at full output swing?
Yes, the TLC080CDR delivers ±57 mA output current, enabling full-rail output swing into 600 Ω loads at 5 V and 12 V supplies. At VDD = 5 V, VOH = 3.2 V and VOL = 0.45 V with 50 mA load (25°C), achieving >4.7 V peak-to-peak swing. This meets professional audio line-driving requirements without external buffers or transformers.
What is the purpose of Pins 1 and 8 on the TLC080CDR?
Pins 1 and 8 on the TLC080CDR are dedicated offset nulling terminals. Connecting a 10 kΩ potentiometer between them, with the wiper grounded, allows precise adjustment of input offset voltage down to <10 µV. This capability is essential for DC-critical applications like precision integrators, weigh scale amplifiers, and zero-drift sensor interfaces where residual offset would accumulate or distort measurements.
