Product details
Overview
TLV4111IDGNRG4 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 at 5 V, featuring 2.7 MHz unity-gain bandwidth, 1.5 V/µs slew rate, 700 µA per channel supply current, and operation across −40°C to 125°C industrial temperature range.
For engineers reviewing the TLV4111IDGNRG4 datasheet, TLV4111IDGNRG4 pinout, TLV4111IDGNRG4 application, or TLV4111IDGNRG4 equivalent, this page provides verified specifications, MSOP PowerPAD® package thermal design guidance, output voltage vs. load current curves, shutdown behavior (not applicable to TLV4111), and real-world use cases in solenoid drivers and precision analog front-ends.
Technical Context
The TLV4111IDGNRG4 employs a robust output stage capable of sourcing/sinking up to ±320 mA at 5 V while maintaining rail-to-rail swing and low distortion (<0.15% THD+N at 100 Hz). Its 2.7 MHz gain-bandwidth product and 66° phase margin support stable unity-gain follower configurations driving capacitive loads up to 1 nF without external compensation.
Designed for single-supply systems from 2.5 V to 6 V, it features input common-mode range extending to GND and VDD−1.5 V, CMRR ≥63 dB, PSRR ≥65 dB, and input offset voltage ≤3.5 mV over full temperature range - enabling direct interfacing with microcontroller ADCs and DACs without level-shifting.
Key Specifications

Pinout & Package
The TLV4111IDGNRG4 is housed in an 8-pin MSOP PowerPAD® package (DGN) with exposed thermal pad on underside - requiring PCB soldering of the pad to ground plane for optimal thermal performance (θJA = 52.7°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 4 (GND) | Analog ground reference | Primary return path for output current and input bias; must connect to low-impedance ground plane |
| 5 (NC) | No internal connection | Unused pin; no internal bond wire - electrically isolated |
| 6 (VDD) | Positive supply rail | Accepts 2.5–6 V; decoupling capacitor (0.1 µF ceramic) required within 5 mm |
| 7 (OUT) | Amplifier output | Capable of ±320 mA at 5 V; requires series RNULL (≤20 Ω) for >1 nF capacitive loads |
| 8 (NC) | No internal connection | Unused pin; must not be connected to avoid parasitic coupling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-output-drive operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA547T | Higher supply voltage (up to 60 V), lower bandwidth (1.2 MHz), higher quiescent current (6 mA) | Better suited for 24–48 V industrial actuators; less ideal for 3.3 V portable systems | Select when >10 V supply or >500 mA peak current is required; avoid if low power or high speed is critical |
| TPS54202 | Not an op-amp - synchronous buck regulator with integrated FETs; no analog amplification function | Replaces power delivery, not signal conditioning; cannot perform sensor buffering or current sensing | Not functionally equivalent; only consider for replacing power stages, not analog signal paths |
Compared with OPA547T, TLV4111IDGNRG4 offers 4.5× lower supply current and 2.25× higher bandwidth but limits max supply to 6 V; compared with TPS54202, it performs analog signal amplification rather than DC-DC conversion - making them non-interchangeable in circuit function.

FAQ
Does TLV4111IDGNRG4 include a shutdown feature?
No, TLV4111IDGNRG4 does not have a shutdown pin. The shutdown function is only available on TLV4110 and TLV4113 variants per the official datasheet. TLV4111IDGNRG4 operates continuously when powered and draws 700 µA per channel in active mode across its full −40°C to 125°C range.
What is the maximum continuous output current for TLV4111IDGNRG4 at 125°C ambient?
At TA = 125°C, the maximum continuous output current for TLV4111IDGNRG4 is 110 mA per the Absolute Maximum Ratings table, based on junction temperature limitation (TJ ≤ 150°C) and thermal resistance of the MSOP PowerPAD® package (θJA = 52.7°C/W). Derating is required above 105°C junction temperature.
Can TLV4111IDGNRG4 drive a 10 nF capacitive load directly?
No - driving >1 nF capacitive loads directly risks instability due to reduced phase margin. The datasheet recommends adding a series resistor (RNULL ≤ 20 Ω) between TLV4111IDGNRG4 output and the 10 nF load to restore stability, as shown in Figure 27. This snubber configuration maintains >45° phase margin.
Is the thermal pad of TLV4111IDGNRG4 electrically connected to any internal node?
No, the exposed thermal pad on the TLV4111IDGNRG4 MSOP PowerPAD® package is electrically isolated from all internal terminals per Figure 30 and SLMA002 application report. It must be soldered to PCB ground for thermal conduction but carries no electrical signal or bias requirement beyond mechanical and thermal anchoring.
What is the input offset voltage drift specification for TLV4111IDGNRG4?
The input offset voltage drift for TLV4111IDGNRG4 is 3 µV/°C at 25°C, as specified in the Electrical Characteristics table under "Offset voltage drift" (αVIO). This low drift ensures minimal output error accumulation over temperature in precision DC-coupled applications such as strain gauge amplifiers.
