Product details
Overview
TLC080IDR 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 is designed for high-fidelity audio buffering, industrial sensor signal conditioning, and active filter stages requiring robust output current.
For engineers reviewing the TLC080IDR datasheet, TLC080IDR pinout, TLC080IDR application, or TLC080IDR equivalent, key selection criteria include its guaranteed –40°C to 125°C industrial temperature rating, ultralow 125 µA/channel shutdown current, 60 µV max input offset voltage, and MSOP-8 PowerPAD™ package enabling high-density thermal management in space-constrained designs.
Technical Context
The TLC080IDR implements a CMOS-input / bipolar-output BiMOS architecture that combines >1 GΩ differential input resistance with ±57 mA sourcing/sinking capability-enabling direct driving of low-impedance loads like 600 Ω audio lines or capacitive DAC buffers without external boost stages. Its internal offset nulling pins support precision DC-coupled configurations.
It integrates an active shutdown control (SHDN pin) that reduces supply current to 125 µA per channel while maintaining fast 0.47 µs turn-on time and 2.5 µs turn-off time at VDD = 12 V. The device achieves 130 dB power supply rejection ratio and 110 dB CMRR over its full operating voltage and temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2340UA/2K5 | Lower bandwidth (5.5 MHz), no shutdown, SO-8 package only, higher VIO (125 µV max) | Lacks shutdown and thermal performance; unsuitable for battery-powered or high-temp industrial use | Select when cost sensitivity outweighs temp range and power savings; verify layout compatibility with SO-8 footprint |
| LM7321MAX/NOPB | Higher supply current (1.3 mA), no shutdown, wider VIO range (±1.8 mV), same MSOP-8 package | Not rated for 125°C operation; lower output drive (±80 mA but with higher thermal resistance) | Prefer for general-purpose designs where shutdown is unnecessary and extended temp is not required |
Compared with OPA2340UA/2K5 and LM7321MAX/NOPB, the TLC080IDR uniquely combines industrial temperature rating, integrated shutdown, and high output drive in an MSOP PowerPAD™ package-making it the only option among the three qualified for automotive under-hood and high-reliability industrial control applications requiring low standby power.

FAQ
What is the maximum output current capability of the TLC080IDR?
The TLC080IDR delivers ±57 mA output current when sourcing (IOH) at VDD – 1.5 V and sinking (IOL) at 0.5 V above GND. This is verified across the full –40°C to 125°C operating range and enables direct driving of 600 Ω audio loads or capacitive DAC inputs without external buffers. The TLC080IDR maintains this performance with <1% gain error at full output swing.
Does the TLC080IDR support rail-to-rail input operation?
Yes, the TLC080IDR supports rail-to-rail input common-mode voltage range from GND to VDD – 2 V, confirmed across all operating conditions including VDD = 4.5 V to 16 V and temperatures from –40°C to 125°C. This allows direct interfacing with sensors, DACs, and other single-supply components without level-shifting circuitry, simplifying design and reducing component count in the TLC080IDR-based signal chain.
What is the purpose of Pins 1 and 8 on the TLC080IDR?
Pins 1 and 8 on the TLC080IDR are dedicated offset null terminals. They connect to the ends of an external 10 kΩ potentiometer (wiper to VDD/2 or GND depending on configuration) to manually trim input offset voltage to <10 µV. These pins are optional-leaving them unconnected results in standard 60 µV max VIO performance. Their inclusion enables precision DC-coupled applications such as strain-gauge amplification where zero-error calibration is critical for the TLC080IDR implementation.
How does the shutdown feature of the TLC080IDR function electrically?
The TLC080IDR shutdown pin (Pin 5) is an active-low logic input: asserting SHDN ≤ 0.8 V disables the amplifier core and reduces supply current to 125 µA per channel, while SHDN ≥ 2 V enables normal operation. Turn-on time is 0.47 µs and turn-off time is 2.5 µs at VDD = 12 V, enabling microsecond-scale power gating in battery-powered systems using the TLC080IDR. No external pull-up is required due to internal biasing.
Is the TLC080IDR compatible with standard MSOP-8 footprints?
Yes, the TLC080IDR uses the industry-standard 8-pin MSOP (DGN) package with 0.65 mm pitch and 3.0 mm × 3.0 mm body size, fully compatible with IPC-7351B MSOP-8 land patterns. Its exposed thermal pad (PowerPAD™) requires solder paste stencil design matching TI's recommended layout in SLMA001-ensuring optimal thermal performance and mechanical reliability in the final TLC080IDR assembly.
