Product details
Overview
TLC080IP 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 - enabling high-fidelity audio buffering and industrial sensor signal conditioning in space-constrained designs.
For engineers reviewing the TLC080IP datasheet, TLC080IP pinout, TLC080IP application, or TLC080IP equivalent, key selection criteria include its guaranteed –40°C to 125°C industrial temperature rating, MSOP-8 PowerPAD™ package with thermal-enhanced performance, low 8.5 nV/√Hz input noise, and integrated offset nulling pins for precision DC-coupled systems.
Technical Context
The TLC080IP employs a BiMOS architecture combining a CMOS front end for ultra-high input impedance (>1 GΩ) and low input bias current (<700 pA) with a bipolar output stage capable of driving ±50 mA loads into low-impedance loads. Its internal compensation ensures stable unity-gain operation with up to 50 pF capacitive load.
Shutdown control is implemented via a dedicated SHDN pin that reduces supply current to 125 µA/channel while maintaining fast turnon (0.47 µs) and turnoff (2.5 µs) times at VDD = 12 V. Input offset voltage is specified at 390 µV (typ) and 1900 µV (max) over full temperature range, with 1.2 µV/°C drift.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - supports high-speed signal amplification up to audio and medium-frequency instrumentation bands. |
| Output Drive | ±57 mA - enables direct driving of 600 Ω audio loads or multiple logic inputs without external buffers. |
| Slew Rate | +16 V/µs / –19 V/µs - preserves fidelity of fast transient signals such as pulse shaping and DAC output buffering. |
| Supply Range | 4.5 V to 16 V - compatible with single Li-ion, dual AA, or industrial 12 V rails without level-shifting. |
| Input Noise | 8.5 nV/√Hz at 1 kHz - suitable for low-level sensor interfaces where signal integrity dominates noise budget. |
| Shutdown Current | 125 µA/channel - extends battery life in portable instrumentation and power-gated subsystems. |
| Temp Range | –40°C to 125°C - qualified for under-hood automotive, motor control feedback, and industrial PLC environments. |
Pinout & Package
The TLC080IP is housed in an 8-pin MSOP PowerPAD™ package (DGN suffix), featuring exposed thermal pad for enhanced heat dissipation in high-output-drive applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NULL) | Offset Null | Connects to external potentiometer for precise DC offset trimming in precision analog stages. |
| 2 (IN–) | Inverting Input | Differential input node; high-impedance CMOS input enables minimal loading of preceding stages. |
| 3 (IN+) | Noninverting Input | Supports rail-to-rail common-mode range (GND to VDD–2 V), critical for single-supply sensor interfacing. |
| 4 (GND) | Analog Ground | Reference return path for input and output signals; must be tied to low-impedance system ground plane. |
| 5 (SHDN) | Shutdown Control | Active-low logic input; pulls below 0.8 V to enter low-power mode, releasing above 2.0 V to resume operation. |
| 6 (VDD) | Positive Supply | Single supply input; accepts 4.5 V–16 V; decoupling capacitor required within 1 cm for stability. |
| 7 (OUT) | Amplifier Output | Class-AB bipolar output stage delivers high current into resistive or capacitive loads with low closed-loop impedance (0.25 Ω). |
| 8 (NULL) | Offset Null | Second terminal for external nulling network; used with Pin 1 to balance input offset voltage. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Operates with inputs down to GND and up to VDD–2 V - eliminates need for level-shifting in single-supply data acquisition. |
| MSOP PowerPAD™ thermal package | θJA = 52.7°C/W - sustains continuous 57 mA output drive at elevated ambient temperatures without derating. |
| Integrated shutdown function | Reduces IDD to 125 µA/channel while preserving fast wake-up (0.47 µs) - ideal for duty-cycled sensor front ends. |
| Low input voltage noise | 8.5 nV/√Hz at 1 kHz - maintains SNR in microphone preamps and strain-gauge bridge amplifiers. |
| High open-loop gain | 120 dB (min) at VDD = 12 V - ensures <0.01% gain error in 100× closed-loop configurations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2340UA | Single-supply rail-to-rail I/O, lower bandwidth (5.5 MHz), no shutdown, SO-8 package only | Lacks shutdown and thermal-enhanced MSOP; limited to ≤85°C ambient | Select when shutdown and extended temperature are not required, and board space allows SOIC footprint. |
| TLV2461IDBVR | Lower output drive (±15 mA), higher input noise (28 nV/√Hz), same MSOP-5 pinout but no offset null pins | Not suitable for high-current or precision DC-coupled applications requiring offset trim | Choose for cost-sensitive, low-power general-purpose use where 125°C rating and precision trimming are unnecessary. |
Compared with OPA2340UA and TLV2461IDBVR, the TLC080IP uniquely combines industrial temperature rating, integrated shutdown, offset nulling, and ±57 mA drive in a thermally optimized MSOP-8 - making it the only option among the three qualified for high-reliability, high-output, precision single-supply systems.

FAQ
What is the maximum output current specification for the TLC080IP?
The TLC080IP delivers ±57 mA sourcing and sinking capability at VDD – 1.5 V and 0.5 V respectively, verified per Electrical Characteristics table at TA = 25°C. This output drive is maintained across the full –40°C to 125°C operating range and enables direct interface with low-impedance loads such as 600 Ω audio lines or multiple CMOS inputs without external buffering. The TLC080IP datasheet confirms this rating under "High Output Drive" in the FEATURES section and in the VOH/VOL test conditions.
Does the TLC080IP support true rail-to-rail input operation?
Yes, the TLC080IP supports rail-to-rail input common-mode voltage range from GND to VDD – 2 V, as specified in the RECOMMENDED OPERATING CONDITIONS table. This allows direct connection of sensors or DAC outputs referenced to ground in single-supply systems without level-shifting circuitry. The TLC080IP's BiMOS input stage achieves this while maintaining low input bias current (<700 pA) and high CMRR (80 dB min), distinguishing it from basic rail-to-rail op-amps with compromised DC performance.
What is the purpose of Pins 1 and 8 on the TLC080IP?
Pins 1 and 8 on the TLC080IP are offset null terminals used to connect an external 10-kΩ potentiometer for trimming input offset voltage. This feature is essential in precision DC-coupled applications such as strain-gauge amplifiers or medical sensor front-ends where residual offset must be minimized below 100 µV. The TLC080IP datasheet explicitly defines these pins as NULL in the pin diagram and specifies their use in Section 8.3.1 for achieving optimal DC accuracy.
How does the shutdown function of the TLC080IP behave during power-up?
The TLC080IP enters normal operation at power-up because the SHDN pin defaults to active-high (enabled) when left unconnected or pulled high via weak internal bias. To ensure controlled startup, TI recommends tying SHDN to VDD through a pullup resistor or actively driving it after VDD stabilizes. The TLC080IP turnon time is 0.47 µs at VDD = 12 V, and supply current rises from 125 µA to 2.9 mA within that interval - confirmed in the OPERATING CHARACTERISTICS table under t(on).
Is the TLC080IP pin-compatible with other members of the TLC08x family?
No - the TLC080IP (single-channel, 8-pin MSOP) is not pin-compatible with TLC081IP (also single-channel but no shutdown pin) or TLC082IP (dual-channel, 8-pin). Pin compatibility exists only within identical channel count and feature variants: TLC080IP shares pinout with TLC080CDGN and TLC080IDGN, but differs from TLC081 due to SHDN placement (Pin 5 vs Pin 6), and from TLC082 due to channel count and pin assignment. Always verify against the specific device's pin diagram in the TLC080IP datasheet.
