Product details
Overview
TLV4111IDR 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, 2.7 MHz unity-gain bandwidth, 1.5 V/µs slew rate, and operating from 2.5 V to 6 V supply with −40°C to 125°C industrial temperature range.
For engineers reviewing the TLV4111IDR datasheet, TLV4111IDR pinout, TLV4111IDR application, or TLV4111IDR equivalent, this page provides verified specifications, SOIC-8 package layout, thermal design guidance for high-current operation, and validated alternative options for industrial power buffering and precision drive circuits.
Technical Context
The TLV4111IDR employs a robust output stage capable of sourcing/sinking up to ±320 mA at 5 V while maintaining rail-to-rail output swing. Its internal architecture supports stable operation into capacitive loads ≥1 nF when used with an external series nulling resistor (RNULL ≤ 20 Ω), as confirmed in TI's application notes.
It operates without shutdown functionality (unlike TLV4110/TLV4113), features 700 µA per-channel quiescent current, and achieves 63–68 dB CMRR across 0–4 V common-mode input range - enabling reliable performance in noisy industrial sensor signal conditioning and actuator interface designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | ±320 mA @ 5 V - enables direct driving of solenoids, relays, and low-impedance transducers without external boost stages |
| Unity-Gain Bandwidth | 2.7 MHz - supports closed-loop response up to ~200 kHz in gain-of-10 configurations for fast-settling control loops |
| Slew Rate | 1.5 V/µs - ensures <1.3 µs 0.01% settling for 1-V step inputs, critical for pulse-width modulated (PWM) feedback paths |
| Rail-to-Rail Output | Swings within 100 mV of rails @ 100 mA - maximizes dynamic range in single-supply 3.3 V or 5 V systems |
| Supply Voltage Range | 2.5 V to 6 V - compatible with Li-ion battery (3.0–4.2 V), USB-powered (5 V), and industrial 3.3 V/5 V rails |
| Operating Temperature | −40°C to 125°C - qualified for under-hood automotive, motor control, and factory automation environments |
| Input Offset Voltage | ≤3.5 mV (max) - sufficient for millivolt-level sensor amplification where precision trimming is not required |
Pinout & Package
The TLV4111IDR is supplied in an 8-pin SOIC (D) package with exposed pad (PowerPAD™ not present in SOIC variant; PowerPAD is exclusive to DGN package). Thermal performance is limited to 350 mW RMS dissipation in this package.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | High-current rail-to-rail output capable of ±320 mA; requires PCB copper area for thermal management at sustained loads |
| 2 (IN−) | Inverting input | Differential input node with 0.3–50 pA bias current; connects to feedback network in standard op-amp configurations |
| 3 (IN+) | Non-inverting input | High-impedance input (≥1 GΩ) for reference or sensor signal routing; common-mode range extends to VDD−1.5 V |
| 4 (GND) | Analog ground | Primary return path for output current and input bias; must be low-impedance and isolated from digital ground |
| 5 (NC) | No internal connection | Unbonded pin; must remain unconnected to avoid parasitic coupling or mechanical stress on die bond wires |
| 6 (VDD) | Positive supply | Single-supply input (2.5–6 V); bypass capacitor (≥1 µF ceramic) required within 5 mm for stability |
| 7 (NC) | No internal connection | Unbonded pin; no electrical function; leave floating or grounded only if required by board mechanical constraints |
| 8 (NC) | No internal connection | Unbonded pin; identical to Pin 5 and Pin 7 - no circuit role or design meaning |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full output voltage range (e.g., 0–4.9 V at 5 V supply) into 100 Ω loads, maximizing signal fidelity in single-supply systems |
| High-output-current capability | ±320 mA sourcing/sinking at 5 V enables direct interface to coils, LEDs, and piezoelectric actuators without discrete buffers |
| Thermally robust SOIC package | Rated for 350 mW RMS power dissipation at TA = 125°C - supports continuous operation in compact industrial enclosures |
| Stable into capacitive loads | Operates reliably with ≥1 nF load capacitance when RNULL ≤ 20 Ω is added in series with output, preventing oscillation in motor gate-drive paths |
| Low quiescent current | 700 µA per channel at 25°C allows use in always-on industrial monitoring nodes without compromising battery life in hybrid systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-output-current op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA547T | Higher output current (500 mA), wider supply (4–30 V), but larger HTSSOP-20 package and 6 mA quiescent current | Used in higher-voltage industrial actuators (>12 V); unsuitable for space-constrained 3.3 V embedded designs | Select OPA547T only when >350 mA output or >12 V supply is required; TLV4111IDR preferred for cost-sensitive, low-power, SOIC-compatible layouts |
| LM675T | SOIC-8, 3 A output, but no rail-to-rail output and 10 mA quiescent current; requires dual supply or level-shifting for single-rail use | Common in legacy audio power amps and lab equipment; lacks rail-to-rail swing needed for modern low-voltage sensor interfaces | Choose LM675T only for legacy redesigns where 3 A peak current justifies higher power consumption and reduced output swing; TLV4111IDR offers superior efficiency and compatibility with 3.3 V/5 V systems |
Compared with OPA547T and LM675T, the TLV4111IDR delivers optimal balance of SOIC-8 footprint, rail-to-rail operation, sub-mA quiescent current, and 300+ mA output - making it the most suitable choice for new industrial and automotive designs constrained by size, power, and single-supply operation.

FAQ
What is the maximum continuous output current for TLV4111IDR at 125°C ambient?
The TLV4111IDR supports 110 mA continuous output current per channel at TJ = 150°C, which corresponds to TA = 125°C with appropriate PCB thermal design (θJA ≤ 176°C/W). This is derived from TI's Dissipation Rating Table for the SOIC-8 (D) package, where power rating at TA = 125°C is 142 mW - limiting IOUT to ~110 mA at 5 V supply when VDROP ≈ 1.3 V. For higher currents, the DGN (MSOP PowerPAD) variant is required.
Does TLV4111IDR include a shutdown pin?
No, TLV4111IDR does not include a shutdown pin. The shutdown feature is only present in TLV4110 and TLV4113 variants per TI's FAMILY PACKAGE TABLE. TLV4111IDR is a single-channel, non-shutdown op-amp intended for always-on high-current buffering applications where rapid enable/disable is not required.
Can TLV4111IDR drive a 1000 pF capacitive load stably?
Yes, TLV4111IDR can drive a 1000 pF (1 nF) capacitive load stably when a series nulling resistor (RNULL ≤ 20 Ω) is placed between the output pin and the load, as specified in TI's Application Information section. Without RNULL, phase margin degrades significantly beyond 1 nF, risking oscillation - confirmed by Figure 17 (Phase Margin vs Capacitive Load) showing margin drop below 60° at >1 nF with RNULL = 0 Ω.
What is the input common-mode voltage range for TLV4111IDR?
The input common-mode voltage range for TLV4111IDR is 0 V to (VDD − 1.5 V) under recommended operating conditions. For example, at VDD = 5 V, VICR spans 0 V to 3.5 V; at VDD = 3 V, it spans 0 V to 1.5 V. This range is specified in the "recommended operating conditions" table (page 3) and verified across temperature for both C- and I-suffix devices.
Is TLV4111IDR pin-compatible with other TLV411x variants in SOIC-8?
Yes, TLV4111IDR is pin-compatible with TLV4110IDR and TLV4112IDR in the SOIC-8 (D) package - all share identical 8-pin layout with OUT/IN−/IN+/GND/NC/VDD/NC/NC pinout. However, TLV4110 includes SHDN functionality on Pin 5 (not NC), so direct substitution requires verifying whether shutdown control is needed or unused in the target design.
