Product details
Overview
TLV4111CDGN 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 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 700 µA per channel quiescent current. It targets industrial sensor excitation and solenoid control where robust drive capability and wide supply range are critical.
For engineers reviewing the TLV4111CDGN datasheet, TLV4111CDGN pinout, TLV4111CDGN application, or TLV4111CDGN equivalent, key selection criteria include confirmed 300+ mA continuous output drive in MSOP PowerPAD™ package, thermal performance validation at TJ ≤ 105°C, rail-to-rail output swing under load, and absence of shutdown functionality - distinguishing it from TLV4110/TLV4113 variants.
Technical Context
This op-amp employs a proprietary output stage architecture enabling >300 mA sourcing/sinking while maintaining rail-to-rail output swing down to 200 mV from each rail at 100 mA load. Its internal compensation supports stable operation with capacitive loads up to 1 nF without external snubbing, and its low input bias current (≤100 pA) minimizes offset errors in high-impedance sensor interfaces.
The device operates across 0°C to 70°C (C-suffix), uses a non-inverting/inverting input pair with grounded reference, and relies on external feedback networks for gain configuration. Its thermal design centers on the exposed PowerPAD™ die attach pad, requiring PCB copper area and vias tied to GND for junction-to-ambient thermal resistance of 52.7°C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | ±320 mA (measured at 0.5 V from rail, VDD = 5 V); enables direct driving of coils, relays, and LED strings without external transistors. |
| Unity-Gain Bandwidth | 2.7 MHz; supports closed-loop gain ≥1 with <1% settling error within 1.3 µs for 0.01% accuracy. |
| Slew Rate | 1.5 V/µs (VDD = 5 V); ensures faithful reproduction of fast-rising control signals in PWM-based actuator interfaces. |
| Rail-to-Rail Output | Swings to within 200 mV of VDD and GND at 100 mA load; maximizes dynamic range in single-supply systems. |
| Supply Voltage Range | 2.5 V to 6 V; compatible with Li-ion, 3.3 V logic, and 5 V industrial rails without level-shifting. |
| Quiescent Current | 700 µA per channel; allows battery-powered designs to sustain >1-year runtime with microamp-level sleep modes. |
| Input Offset Voltage | 3500 µV max (full range); sufficient for precision current sensing when combined with external zero-drift calibration. |
Pinout & Package
The TLV4111CDGN is housed in an 8-pin MSOP PowerPAD™ package (DGN), featuring an exposed thermal pad on the underside electrically isolated from all terminals and intended for soldering to a GND-connected PCB copper area.
| 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 functional impact. |
| 2 (IN−) | Inverting input | Differential input node; high impedance (1000 GΩ) enables direct connection to resistive sensor bridges. |
| 3 (IN+) | Non-inverting input | Reference input node; common-mode range extends from GND to VDD − 1.5 V for single-supply operation. |
| 4 (GND) | Ground reference | Primary return path for supply and output current; must connect directly to low-impedance ground plane. |
| 5 (NC) | No internal connection | Unused pin; identical handling as Pin 1 - no routing required. |
| 6 (VDD) | Positive supply | Accepts 2.5–6 V; bypass capacitor (0.1 µF ceramic) required within 5 mm of this pin to suppress supply noise. |
| 7 (OUT) | Amplifier output | Capable of ±320 mA drive; requires series resistor (≤20 Ω) when driving >1 nF capacitive loads to prevent oscillation. |
| 8 (NC) | No internal connection | Unused pin; matches SOIC/DIP pinout for footprint compatibility but carries no internal bond wire. |
Key Features
| Feature | Design Value |
|---|---|
| High-output-current buffer | Delivers >300 mA continuously without external boost stages - eliminates discrete transistor stages in solenoid drivers. |
| Rail-to-rail output swing | Maintains >93% of full-scale voltage range at 100 mA load, maximizing signal fidelity in 3.3 V/5 V data acquisition front-ends. |
| Thermally enhanced PowerPAD™ | Reduces θJA to 52.7°C/W vs. 176°C/W in SOIC, enabling >2.3 W power dissipation and sustained 350 mA RMS output. |
| Wide supply voltage range | Operates from 2.5 V (single-cell LiFePO₄) to 6 V (industrial 5 V rails with tolerance), simplifying power architecture across platforms. |
| Low quiescent current | 700 µA per channel allows integration into always-on sensor nodes without compromising battery life in portable instrumentation. |

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 |
|---|---|---|---|
| OPA547T | Higher supply voltage (up to 60 V), lower bandwidth (1 MHz), higher quiescent current (10 mA), TO-220 package. | Designed for high-voltage industrial actuators; unsuitable for low-voltage portable systems due to minimum 10 V supply requirement. | Select OPA547T only when >24 V operation or >500 mA peak current is required; TLV4111CDGN preferred for 2.5–6 V, space-constrained designs. |
| LM675T | SOIC-16 package, 20 MHz bandwidth, 100 mA continuous output, no rail-to-rail output, 10 mA quiescent current. | Targeted at audio and general-purpose power amplification; lacks rail-to-rail swing and thermal efficiency for compact coil drivers. | Choose LM675T for cost-sensitive, non-miniaturized designs where PCB area is not constrained and 200 mV output headroom is acceptable. |
Compared with OPA547T and LM675T, TLV4111CDGN uniquely balances ultra-low quiescent current (700 µA), rail-to-rail output, and 320 mA drive in a thermally optimized 3 × 3 mm MSOP PowerPAD™ - making it the only option suitable for battery-powered, space-limited solenoid and sensor excitation applications below 6 V.

FAQ
What is the maximum continuous output current specification for TLV4111CDGN?
The TLV4111CDGN delivers ±320 mA continuous output current when measured at 0.5 V from the supply rail under VDD = 5 V conditions at 25°C. At elevated junction temperatures (TJ ≤ 105°C), the continuous RMS output current is rated at 350 mA - validated only when mounted on a PCB with the PowerPAD™ thermally connected to GND via recommended copper area and vias.
Does TLV4111CDGN include a shutdown feature?
No, TLV4111CDGN does not include a shutdown terminal. Unlike TLV4110 and TLV4113 variants, this part has no SHDN pin and operates continuously when powered. The pinout shows three NC (no-connect) terminals instead of a dedicated shutdown input, confirming its always-on operational mode.
What thermal design requirements apply to TLV4111CDGN's PowerPAD™ package?
TLV4111CDGN's DGN package requires the exposed PowerPAD™ to be soldered to a GND-connected PCB copper area with five 13-mil vias beneath it, all thermally connected to an internal ground plane. This achieves θJA = 52.7°C/W; omitting this results in thermal throttling and potential failure above 110 mA continuous load.
Can TLV4111CDGN drive capacitive loads without oscillation?
TLV4111CDGN remains stable with capacitive loads ≤1 nF when configured as a unity-gain buffer. For loads >1 nF, a series resistor (RNULL ≤20 Ω) must be placed between the OUT pin and the capacitive node - as documented in Figure 27 of the SLOS289E datasheet - to maintain phase margin above 66° and prevent high-frequency ringing.
What is the input common-mode voltage range for TLV4111CDGN?
The input common-mode voltage range for TLV4111CDGN is specified as 0 V to VDD − 1.5 V under recommended operating conditions. At VDD = 5 V, this permits inputs from 0 V to 3.5 V; at VDD = 2.5 V, the upper limit is 1.0 V - ensuring compatibility with ground-referenced sensors and mid-supply references in single-supply systems.
