Product details
Overview
TLV4111IDGNR 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 TLV4111IDGNR datasheet, TLV4111IDGNR pinout, TLV4111IDGNR application, or TLV4111IDGNR equivalent, this page provides verified specifications, thermal-aware package guidance for the MSOP PowerPAD™ (DGN) package, real-world output voltage vs. load curves, and selection-critical alternatives for high-current op-amp replacement in motor drive, solenoid control, and precision analog output stages.
Technical Context
The TLV4111IDGNR employs a proprietary output stage architecture enabling >300 mA continuous sourcing/sinking while maintaining rail-to-rail swing and low output impedance (<1 Ω at DC). Its internal compensation ensures stability with capacitive loads up to 1 nF without external snubbing-beyond that, a series RNULL ≤ 20 Ω is recommended per TI application note SLOS289E.
Unlike standard op-amps, the TLV4111IDGNR's thermal design centers on the exposed PowerPAD™ die attach pad, which reduces θJA to 52.7°C/W when properly soldered to PCB copper-enabling 2.37 W power dissipation at TA ≤ 25°C, critical for sustained high-current operation without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current (Continuous) | ±320 mA @ 5 V (measured at 0.5 V from rail); enables direct driving of 15 Ω coils or 100 Ω loads at full swing |
| Unity-Gain Bandwidth | 2.7 MHz; supports stable closed-loop gain ≥1 with ≤10 pF capacitive load and 100 Ω source impedance |
| Slew Rate | 1.5 V/µs @ 5 V; delivers 1 VPP step response in <1 µs, suitable for fast-settling analog outputs |
| Supply Voltage Range | 2.5 V to 6 V; compatible with Li-ion (3.0–4.2 V), 3.3 V, and 5 V systems without level-shifting |
| Rail-to-Rail Output | Swings within 100 mV of VDD and GND @ 100 mA; preserves dynamic range in low-voltage sensor interfaces |
| Input Offset Voltage | 175 µV (typ), 3.5 mV (max); enables <0.1% accuracy in 3.3 V reference buffers without trimming |
| Shutdown Current | 3.4 µA (typ) per channel; not applicable-TLV4111 lacks shutdown pin (unlike TLV4110/4113) |
Pinout & Package
The TLV4111IDGNR is housed in an 8-pin MSOP PowerPAD™ (DGN) package with an exposed thermal pad electrically isolated from all terminals. The pad must be soldered to a PCB ground plane via five 13-mil vias for optimal thermal performance (θJA = 52.7°C/W).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection; must be left floating or tied to GND per layout guidelines |
| 2 | IN− | Inverting input; high-impedance node (1000 GΩ differential resistance) for feedback networks |
| 3 | IN+ | Non-inverting input; common-mode range extends 0 V to VDD−1.5 V for single-supply sensing |
| 4 | GND | Power and signal reference; connects directly to thermal pad; must tie to system ground plane |
| 5 | NC | No internal connection; must be left floating or tied to GND per layout guidelines |
| 6 | VDD | Positive supply; accepts 2.5–6 V; decoupling capacitor (0.1 µF ceramic) required within 5 mm |
| 7 | OUT | Amplifier output; capable of ±320 mA continuous drive; requires thermal pad for >200 mA operation |
| 8 | NC | No internal connection; must be left floating or tied to GND per layout guidelines |

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 |
|---|---|---|---|
| TLC071CDR | Higher VDD max (16 V), lower output current (100 mA), no PowerPAD™; SOIC-8 only | Requires external boost transistor for >100 mA loads; unsuitable for space-constrained PCBs needing thermal relief | Choose TLC071CDR only if supply exceeds 6 V or thermal budget allows SOIC-8's 176°C/W θJA |
| OPA547TP | Higher output current (500 mA), wider VDD (8–60 V), TO-220 package; no rail-to-rail output | Outputs swing to within 3 V of rails-requires level-shifting for 0–5 V systems; needs heatsink above 1 W | Choose OPA547TP only for >6 V supplies or where 500 mA peak is mandatory; avoid for compact 3.3/5 V designs |
Compared with TLC071CDR and OPA547TP, the TLV4111IDGNR uniquely combines rail-to-rail output, 320 mA drive, and ultra-low thermal resistance in a 3 mm × 3 mm MSOP package-making it the only option for space-constrained, low-voltage, high-current analog output stages without external support circuitry.

FAQ
What is the maximum continuous output current for TLV4111IDGNR at 125°C ambient?
The TLV4111IDGNR delivers ±320 mA continuous output current at 25°C ambient and 5 V supply. At 125°C ambient, thermal limits reduce continuous current to 474 mA (based on 52.7°C/W θJA and 150°C max junction temperature). Derating curves in Figure 4 and 6 of SLOS289E confirm 2.6 VOH at 100 mA and 4.6 VOH at 200 mA under these conditions-validating safe operation up to 200 mA at full temperature range.
Does TLV4111IDGNR include a shutdown pin?
No, TLV4111IDGNR does not have a shutdown pin. The shutdown feature is exclusive to TLV4110 and TLV4113 variants per the FAMILY PACKAGE TABLE in SLOS289E. TLV4111IDGNR has NC pins at positions 1, 5, and 8, with no internal connection to a shutdown control terminal-so it operates continuously when powered.
Can TLV4111IDGNR drive a 10 nF capacitive load stably?
No-TLV4111IDGNR is stable up to 1 nF capacitive load without external compensation. For 10 nF loads, TI application note SLOS289E Section "Driving a Capacitive Load" mandates a series RNULL resistor (≤20 Ω) between OUT and the load to maintain ≥66° phase margin and prevent oscillation, as confirmed by Phase Margin vs. Capacitive Load (Figure 17).
What is the purpose of the exposed thermal pad on TLV4111IDGNR?
The exposed thermal pad on TLV4111IDGNR is electrically isolated but thermally coupled to the die, reducing θJA from 176°C/W (SOIC) to 52.7°C/W. When soldered to a PCB ground plane via five 13-mil vias, it enables 2.37 W power dissipation at 25°C ambient-critical for sustaining >200 mA output without thermal shutdown.
How does TLV4111IDGNR compare to standard op-amps in solenoid driving applications?
TLV4111IDGNR replaces discrete transistor + op-amp solutions by integrating ±320 mA drive, rail-to-rail swing, and PowerPAD™ thermal management. Standard op-amps (e.g., LM358) typically deliver <50 mA and require external MOSFETs-adding complexity, board area, and failure points. TLV4111IDGNR achieves same function in one 3 mm × 3 mm IC with guaranteed 125°C operation.
