Product details
Overview
TLV4111ID from Texas Instruments is a single-channel, rail-to-rail output operational amplifier optimized for high-current buffer and coil driver applications, delivering >300 mA continuous output current at 5 V, with 2.7 MHz unity-gain bandwidth, 1.5 V/µs slew rate, and operation across −40°C to 125°C industrial temperature range.
For engineers reviewing the TLV4111ID datasheet, TLV4111ID pinout, TLV4111ID application, or TLV4111ID equivalent, this page provides verified package mapping (SOIC-8), confirmed thermal performance in industrial-grade operation, real-world output voltage swing vs. load data, and validated alternatives for high-current op-amp selection in motor drive, solenoid control, and precision analog output stages.
Technical Context
The TLV4111ID employs a robust output stage capable of sourcing/sinking up to ±320 mA at 5 V while maintaining rail-to-rail output swing down to within 200 mV of rails at 100 mA load. Its internal architecture supports stable unity-gain operation with 66° phase margin into 100 Ω + 10 pF loads, and features low input offset drift (3 µV/°C) and 55 nV/√Hz input voltage noise at 100 Hz.
Unlike standard op-amps, the TLV4111ID is thermally engineered for sustained high-current delivery: its SOIC-8 package is rated for 350 mW RMS dissipation (700 mW peak), and it achieves <0.7 µs 0.1% settling time in voltage-follower configuration-critical for fast analog output buffering in programmable logic controllers and industrial I/O modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | ±320 mA at 5 V supply - enables direct driving of coils, relays, and low-impedance DAC outputs without external transistors |
| Rail-to-Rail Output | Swings within 200 mV of VDD/GND at 100 mA - preserves dynamic range in 3.3 V and 5 V systems with tight supply margins |
| Unity-Gain Bandwidth | 2.7 MHz - supports stable closed-loop operation up to 200 kHz with 100 Ω load, suitable for fast-settling analog output stages |
| Slew Rate | 1.5 V/µs - ensures ≤0.7 µs 0.1% settling for 1 V step, critical for pulse-width modulated analog reconstruction |
| Supply Voltage Range | 2.5 V to 6 V - compatible with Li-ion, USB, and industrial 3.3 V/5 V rails without level-shifting circuitry |
| Operating Temperature | −40°C to 125°C - qualified for under-hood automotive, factory automation, and outdoor industrial environments |
| Input Offset Voltage | 4 mV max (full range) - enables accurate DC-coupled signal conditioning in sensor front-ends and current-sense amplifiers |
Pinout & Package
TLV4111ID is packaged in an 8-pin SOIC (D package) with exposed pad not electrically connected. The device uses standard op-amp pinout: non-inverting input (IN+), inverting input (IN−), output (OUT), ground (GND), and supply (VDD), with two no-connect (NC) pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No internal connection | Unused pin; must be left floating or tied to GND per layout best practice - no electrical function |
| 2 (IN−) | Inverting input | Accepts feedback network input; high-impedance node (1000 GΩ) enabling precision gain-setting with minimal loading |
| 3 (IN+) | Non-inverting input | High-impedance input (1000 GΩ); common-mode range extends from GND to VDD−1.5 V for wide signal capture |
| 4 (GND) | Analog ground reference | Primary return path for output current and bias currents; must be connected to low-impedance system ground plane |
| 5 (NC) | No internal connection | Unused pin; no internal bond wire - electrically isolated and thermally inert |
| 6 (VDD) | Positive supply rail | Accepts 2.5–6 V; PSRR of 65–79 dB suppresses supply ripple in noisy industrial power domains |
| 7 (OUT) | Amplifier output | Delivers >300 mA continuously; output impedance <1 Ω at DC, rising to ~10 Ω at 1 MHz - requires RNULL for >1 nF capacitive loads |
| 8 (NC) | No internal connection | Unused pin; no thermal or electrical role - PCB footprint may omit solder mask opening |
Key Features
| Feature | Design Value |
|---|---|
| High-output-current capability | ±320 mA at 5 V enables direct interface to 15 Ω solenoids, 100 Ω DAC loads, and piezo drivers without discrete boost stages |

| Industrial temperature grade | −40°C to 125°C operation with guaranteed 4 mV max input offset ensures accuracy in uncontrolled ambient environments |
| Low quiescent current | 700 µA per channel at 25°C allows use in always-on industrial sensors and battery-backed I/O modules |
| Stable unity-gain operation | 66° phase margin into 100 Ω + 10 pF load eliminates need for external compensation in most buffer configurations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-output-current operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC071CD | Lower output current (100 mA), higher supply voltage (16 V), no rail-to-rail output - swings to within 1.5 V of rails | Not suitable for 3.3 V rail-to-rail buffer or <50 Ω load drive; better for high-voltage, low-current precision apps | Select TLC071CD only when >10 V supplies and <100 mA loads are required; avoid for TLV4111ID's core high-current use cases |
| OPA547TP | Higher output current (500 mA), wider supply (8–60 V), integrated thermal shutdown - but larger TO-220 package and 10× higher quiescent current (7 mA) | Overqualified for 3.3/5 V industrial I/O; TO-220 requires heatsink and violates space constraints in dense PCB layouts | Choose OPA547TP only for >24 V systems or when active thermal protection is mandatory; TLV4111ID offers superior size/power efficiency at 5 V |
Compared with TLC071CD and OPA547TP, TLV4111ID uniquely balances 300 mA output, rail-to-rail swing, 700 µA quiescent current, and SOIC-8 footprint - making it optimal for space- and power-constrained industrial analog output and solenoid drive where neither low-current precision nor high-voltage brute force is needed.

FAQ
What is the maximum continuous output current specification for TLV4111ID at 5 V supply?
The TLV4111ID delivers ±320 mA continuous output current at 5 V supply under recommended operating conditions. This value is measured at 0.5 V from the rail and applies to both sourcing and sinking. For sustained operation, thermal limits require adherence to the SOIC-8 package's 350 mW RMS power dissipation rating - meaning actual usable current depends on ambient temperature and PCB thermal design. TLV4111ID maintains this performance across its full −40°C to 125°C industrial temperature range.
Does TLV4111ID include a shutdown feature?
No, TLV4111ID does not include a shutdown feature. The shutdown function is only available on TLV4110 and TLV4113 variants within the same family. TLV4111ID is a single-channel, non-shutdown op-amp with fixed operation - its pinout contains three NC pins and no SHDN terminal. This simplifies design for always-on applications like analog output buffers and sensor excitation where standby current reduction is not required.
Which package types are offered for TLV4111ID, and what are their thermal characteristics?
TLV4111ID is offered exclusively in the 8-pin SOIC (D) package, rated for 350 mW RMS power dissipation and 700 mW peak dissipation. Its junction-to-ambient thermal resistance (θJA) is 176°C/W. Unlike the MSOP PowerPAD variants (e.g., TLV4111IDGN), the SOIC-8 version lacks an exposed thermal pad - so PCB copper area and via placement become critical for thermal management. For applications exceeding 350 mW average dissipation, the DGN package is recommended.
Can TLV4111ID drive capacitive loads, and if so, what is the recommended approach?
TLV4111ID can drive capacitive loads up to 1 nF directly, but for loads >1 nF, a series resistor (RNULL) must be added between the output and load to maintain stability. Texas Instruments recommends RNULL ≤20 Ω for most applications, placed as close as possible to the TLV4111ID output pin. This snubber configuration restores phase margin and prevents high-frequency ringing or oscillation - confirmed by typical characteristics showing stable pulse response with 50 pF load and RNULL = 20 Ω in the datasheet.
What is the input common-mode voltage range for TLV4111ID, and how does it affect sensor interface designs?
The TLV4111ID has an input common-mode voltage range of 0 V to VDD−1.5 V. At 5 V supply, this spans 0 V to 3.5 V; at 3.3 V supply, it covers 0 V to 1.8 V. This range excludes the top 1.5 V of the supply rail - meaning the device cannot accept inputs near VDD in unity-gain follower configurations. For sensor interfaces requiring full-rail input capture (e.g., bridge sensors biased at VDD/2), designers must ensure signal swing remains within this window or use level-shifting techniques.
