Product details
Overview
TLV4111CD 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 TLV4111CD datasheet, TLV4111CD pinout, TLV4111CD application, or TLV4111CD equivalent, key selection considerations include verified 300 mA continuous output drive (MSOP PowerPAD required above 200 mA), thermal performance in SOIC vs DGN packages, shutdown absence (distinguishing it from TLV4110/TLV4113), and rail-to-rail output swing within 100 mV of rails at 100 mA load.
Technical Context
The TLV4111CD employs a proprietary high-current output stage enabling >300 mA sourcing/sinking while maintaining rail-to-rail output swing down to 100 mV from supply rails at 100 mA. Its 2.7 MHz gain-bandwidth product and 1.5 V/µs slew rate support medium-speed closed-loop buffering without instability under 100 Ω loads.
No internal shutdown circuitry is integrated - unlike TLV4110 and TLV4113 - making TLV4111CD suitable for always-on high-drive applications where power sequencing simplicity and absence of SHDN pin interactions are required. Input bias current remains below 100 pA across 0°C–70°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | ±320 mA at 5 V (measured at 0.5 V from rail); enables direct driving of coils, relays, and low-impedance sensors without external transistors |
| Unity-Gain Bandwidth | 2.7 MHz; supports stable voltage-follower operation up to ~200 kHz with 100 Ω load and 10 pF capacitance |
| Slew Rate | 1.5 V/µs (at 5 V); ensures ≤1.3 µs settling to 0.01% for 1 V step, suitable for pulse amplification in actuator interfaces |
| Supply Voltage Range | 2.5 V to 6 V; compatible with single-cell Li-ion (3.0–4.2 V), 3.3 V logic, and 5 V legacy systems |
| Rail-to-Rail Output | Swings to within 100 mV of VDD/GND at 100 mA; preserves dynamic range in low-voltage sensor signal conditioning |
| Quiescent Current | 700 µA per channel; allows battery-powered designs to sustain >1-year operation on 200 mAh coin cell when active |
| Input Offset Voltage | 3500 µV max (full range); sufficient for precision DC-coupled buffers where <10 mV error is acceptable |
Pinout & Package
TLV4111CD is offered in 8-pin SOIC (D) package with standard op-amp pinout and no shutdown terminal. Thermal performance is limited to 350 mW RMS dissipation in this package; MSOP PowerPAD (DGN) variant required for sustained >200 mA output.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | High-current rail-to-rail output capable of ±320 mA; requires thermal relief in SOIC for >200 mA continuous use |
| 2 (IN−) | Inverting input | Differential input node with 1000 GΩ input resistance; accepts signals from 0 V to VDD−1.5 V common-mode range |
| 3 (IN+) | Non-inverting input | High-impedance input referenced to GND or feedback network; offset voltage drift ≤3 µV/°C |
| 4 (GND) | Power ground | Return path for output current and supply; must be low-impedance for stability with heavy loads |
| 5 (NC) | No internal connection | Unbonded pin; must remain unconnected to avoid parasitic coupling or mechanical stress |
| 6 (VDD) | Positive supply | Accepts 2.5–6 V; PSRR ≥65 dB ensures immunity to supply ripple in noisy industrial environments |
| 7 (NC) | No internal connection | Unbonded pin; PCB layout must omit trace or pad to prevent solder bridging |
| 8 (NC) | No internal connection | Unbonded pin; electrically and thermally isolated from die; no routing or copper fill required |

Applications
| Industrial Sensor Excitation | DC Solenoid / Valve Driver |
|---|---|
Use Scenario: Providing precise, stable current to RTD or strain gauge bridges in factory-floor temperature and pressure transmitters. IC Role / Device Role / Timing Role: High-current voltage follower configured as constant-voltage source for 2-wire or 3-wire bridge excitation.

IC Role / Device Role / Timing Role: Single-supply op-amp used as low-side current sink or high-side buffer depending on configuration. Use Value: Verified ±320 mA output at 5 V enables direct drive of 25 Ω solenoids; thermal design in SOIC limits duty cycle to <30% for continuous operation. |
| Low-Voltage Actuator Interface | High-Current ADC Driver |
Use Scenario: Driving piezoelectric actuators or micro-pumps requiring fast voltage slewing and high peak current in portable medical devices. IC Role / Device Role / Timing Role: Unity-gain buffer between DAC output and capacitive actuator load. Use Value: 1.5 V/µs slew rate supports 100 kHz triangle wave generation into 1 nF; series RNULL (≤20 Ω) prevents oscillation per datasheet guidance. | Use Scenario: Buffering analog sensor outputs into SAR ADCs with switched-capacitor inputs in condition monitoring systems. IC Role / Device Role / Timing Role: Low-output-impedance driver ensuring accurate charge transfer during ADC acquisition window. Use Value: Output impedance <1 Ω at 10 kHz (per Fig. 8) minimizes settling error; 0.01% settling in 1.3 µs meets 1 MSPS ADC timing budgets. |
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 |
|---|---|---|---|
| TLV4111CDGN | Same die, MSOP PowerPAD package with 4.7 °C/W θJC; supports >1 W continuous dissipation and 350 mA RMS output | Required for sustained >200 mA loads or ambient temperatures >55°C; incompatible with SOIC footprints | Select CDGN when thermal budget exceeds SOIC limits; verify PCB thermal pad layout per SLMA002 |
| OPA547TP | Higher 500 mA continuous output, wider 4–36 V supply, but 10× higher 7 mA quiescent current and larger TO-220 package | Better for high-voltage industrial actuators; unsuitable for battery-powered or space-constrained designs | Choose OPA547TP only when >36 V operation or >350 mA continuous drive is mandatory |
Compared with TLV4111CDGN, the TLV4111CD offers identical electrical performance in a legacy SOIC footprint but trades 70% lower thermal capacity for board-level compatibility; versus OPA547TP, it provides 90% lower quiescent current and smaller size at the cost of reduced voltage range and output headroom.

FAQ
What is the maximum continuous output current for TLV4111CD in SOIC package?
The TLV4111CD in 8-pin SOIC (D) package supports 350 mA peak but is thermally limited to 350 mW RMS power dissipation. At 5 V supply and 100 mV saturation, this corresponds to ≤300 mA continuous output. Sustained >200 mA requires careful thermal design or migration to MSOP PowerPAD (TLV4111CDGN).
Does TLV4111CD include a shutdown pin?
No, TLV4111CD does not include a shutdown pin. Unlike TLV4110 and TLV4113, the TLV4111CD is a fixed-function high-drive op-amp with no enable/disable control. Its pinout omits SHDN, and all eight pins are either functional or NC - confirmed by the "TLV4111" row in the FAMILY PACKAGE TABLE showing "-" under SHUTDOWN.
Can TLV4111CD drive capacitive loads, and what is the recommended compensation?
Yes, TLV4111CD can drive capacitive loads up to 1 nF directly. For loads >1 nF, Texas Instruments recommends adding a series resistor (RNULL ≤20 Ω) between the output and load to maintain phase margin >66°, as shown in Figure 27. This prevents ringing or oscillation without degrading DC accuracy or slew rate significantly.
What is the input common-mode voltage range for TLV4111CD?
The input common-mode voltage range for TLV4111CD is 0 V to VDD−1.5 V at room temperature, per Recommended Operating Conditions table. At 5 V supply, this allows inputs from 0 V to 3.5 V; at 2.5 V supply, usable range is 0 V to 1.0 V. The device does not support rail-to-rail input operation.
How does thermal performance differ between TLV4111CD (SOIC) and TLV4111CDGN (MSOP PowerPAD)?
TLV4111CD in SOIC has θJA = 176 °C/W, limiting RMS power to 350 mW. TLV4111CDGN in MSOP PowerPAD achieves θJA = 52.7 °C/W and θJC = 4.7 °C/W, enabling >2.3 W power dissipation and 350 mA RMS output. The PowerPAD variant requires PCB thermal vias and ground-plane connection per SLMA002 guidelines.
