Product details
Overview
TLC080AIDR from Texas Instruments is a single-channel, wide-bandwidth BiMOS operational amplifier with 10 MHz gain-bandwidth product, ±57 mA high-output drive capability, and shutdown functionality. It operates from 4.5 V to 16 V single supply, features 8.5 nV/√Hz input voltage noise, and is rated for –40°C to 125°C industrial temperature range - used in precision audio line drivers and sensor signal conditioning circuits.
For engineers reviewing the TLC080AIDR datasheet, TLC080AIDR pinout, TLC080AIDR application, or TLC080AIDR equivalent, key selection criteria include its rail-to-rail output swing capability (VOL = 0.45 V at 50 mA, VOH = 10.3 V at 50 mA with 12 V supply), low 125 µA shutdown current per channel, and guaranteed common-mode input range extending to ground.
Technical Context
The TLC080AIDR integrates a CMOS front end for ultralow input bias current (≤700 pA) and high input impedance (>1 GΩ), paired with a bipolar output stage enabling ±57 mA sourcing/sinking into heavy loads. Its BiMOS architecture delivers 16 V/µs positive and 19 V/µs negative slew rates while maintaining 60 µV typical input offset voltage.
It supports single-supply operation with VICR spanning GND to VDD–2 V, includes dedicated SHDN pin for logic-controlled power-down, and features offset nulling pins (NULL) for precision DC performance tuning in closed-loop configurations.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA1671AIDR | Lower noise (4.5 nV/√Hz), no shutdown, SOIC-8, 10 MHz GBW, 50 mA output drive | Lacks SHDN pin; optimized for ultra-low-noise audio, not industrial power efficiency | Select when lowest possible noise dominates over power management needs |
| TLV9061IDR | Lower supply current (560 µA), rail-to-rail I/O, 10 MHz GBW, 50 mA output, no offset null pins | No NULL pins; higher input offset (120 µV); better for cost-sensitive consumer designs | Select when board space and BOM count are prioritized over precision trimming |
Compared with OPA1671AIDR and TLV9061IDR, the TLC080AIDR uniquely combines shutdown control, offset nulling capability, and ±57 mA output drive in a single SOIC-8 package - making it the only option among the three qualified for high-current, precision, low-power industrial signal chains requiring long-term DC stability.

FAQ
What is the maximum output current capability of the TLC080AIDR?
The TLC080AIDR 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 –40°C to 125°C operating range. This enables direct driving of 600 Ω audio loads or 20 mA industrial current loops without external transistors. The TLC080AIDR maintains this drive strength while retaining 10 MHz bandwidth and low distortion.
Does the TLC080AIDR support true single-supply operation with input common-mode range including ground?
Yes, the TLC080AIDR supports true single-supply operation with a common-mode input voltage range (VICR) from GND to VDD – 2 V, confirmed across all temperatures and supply voltages (4.5 V to 16 V). This allows direct interfacing with ground-referenced sensors and ADCs without level-shifting circuitry. The TLC080AIDR achieves this via its BiMOS input stage, which eliminates the PNP input limitation found in older TL08x op-amps.
How does the shutdown feature of the TLC080AIDR function, and what is its leakage impact?
The TLC080AIDR shutdown pin (SHDN, Pin 5) is active-low: asserting ≤0.8 V reduces supply current to 125 µA per channel (typical), while ≥2 V enables normal operation. During shutdown, the output enters high-impedance state with <100 nA leakage. This behavior is fully characterized from –40°C to 125°C and enables precise power gating in battery-powered instrumentation. The TLC080AIDR's shutdown recovery time is 0.47 µs (ton) at 12 V supply.
Can the TLC080AIDR be used in unity-gain stable configurations with capacitive loads?
Yes, the TLC080AIDR is unity-gain stable and characterized for capacitive loads up to 50 pF with ≥32° phase margin at 10 kΩ load. For heavier loads (e.g., >100 pF), external isolation resistance (≥10 Ω) is recommended per TI's application guidance. The TLC080AIDR's phase margin degrades predictably with capacitance - 37° at 50 pF (12 V supply) - ensuring robust stability in buffered DAC outputs and cable-driving applications.
What packaging and RoHS compliance status does the TLC080AIDR have?
The TLC080AIDR is supplied in an 8-pin SOIC (D) package with lead finish NiPdAu, compliant with JEDEC J-STD-020 moisture sensitivity level 1 and RoHS Directive 2011/65/EU. It is halogen-free and meets TI's IPC-7095B assembly guidelines. The TLC080AIDR's package dimensions (4.9 mm × 3.91 mm × 1.75 mm) match industry-standard SOIC footprints, enabling drop-in replacement for legacy TL081 variants.
