Product details
Overview
TLV4110IP from Texas Instruments is a single-channel rail-to-rail output operational amplifier with shutdown control, delivering >300 mA continuous output current at 5 V, unity-gain bandwidth of 2.7 MHz, slew rate of 1.5 V/µs, and supply current of 700 µA per channel across 2.5 V to 6 V operation - used as high-current buffer or coil driver in industrial motor control interfaces.
For engineers reviewing the TLV4110IP datasheet, TLV4110IP pinout, TLV4110IP application, or TLV4110IP equivalent, key selection criteria include verified shutdown functionality, thermal performance in MSOP PowerPAD™ package, rail-to-rail output swing under 300 mA load, and guaranteed operation from −40°C to 125°C.
Technical Context
The TLV4110IP integrates a robust output stage capable of sourcing/sinking ±320 mA at 5 V while maintaining rail-to-rail output swing down to 0.1 V from rails at 100 mA. Its internal architecture supports fast turn-on (1 µs) and turn-off (3.3 µs) via dedicated SHDN pin, with shutdown current limited to 15 µA max over full temperature range.
Designed for thermally demanding applications, the device uses Texas Instruments' MSOP PowerPAD™ package (DGN), featuring a thermally enhanced exposed die pad electrically isolated from all terminals and requiring PCB-level thermal vias connected to ground plane for optimal θJA = 52.7°C/W performance.

Pinout & Package
The TLV4110IP is packaged in an 8-pin MSOP PowerPAD™ (DGN) with exposed thermal pad on underside - requires soldering to PCB copper area tied to GND for thermal management and mechanical stability. Pin 1 is NC (no internal connection), Pin 5 is SHDN, Pin 6 is VDD, Pin 7 is OUT, Pin 8 is NC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (NC) | No internal connection | Must be left unconnected; no routing or pull-up/pull-down required |
| Pin 2 (IN−) | Inverting input | Accepts differential feedback signal; high CMRR (68 dB @ 5 V) rejects common-mode noise in noisy environments |
| Pin 3 (IN+) | Non-inverting input | High-impedance input (1000 GΩ) minimizes loading on sensor or DAC output stages |
| Pin 4 (GND) | Analog ground reference | Primary return path for output current and bias currents; must connect to low-impedance system ground plane |
| Pin 5 (SHDN) | Active-high shutdown control | Pull ≥2.1 V (at 3 V supply) or ≥3.8 V (at 5 V supply) to enable; ≤0.9 V / ≤1.65 V to disable; requires external pullup |
| Pin 6 (VDD) | Positive supply rail | Supports 2.5–6 V operation; PSRR = 70 dB ensures immunity to supply ripple in shared-rail systems |
| Pin 7 (OUT) | Amplifier output | Capable of 350 mA RMS continuous drive; thermal derating applies above TJ = 105°C (see dissipation rating table) |
| Pin 8 (NC) | No internal connection | Must be left unconnected; not internally bonded or tested |

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 |
|---|---|---|---|
| TLC071CDR | No shutdown pin; 100 mA output current; SOIC-8 package only; θJA = 176°C/W | Lacks power-gating capability; unsuitable for battery-critical designs; thermal limit restricts continuous drive to <200 mA | Select only if shutdown is unnecessary and thermal budget allows SOIC mounting |
| OPA547FKTWT | Higher 500 mA output; wider 8–36 V supply range; TO-263 package; no rail-to-rail output | Requires ≥8 V supply; output swing limited to 2 V from rails - incompatible with 3.3 V logic interfacing | Choose for higher-voltage industrial loads where rail-to-rail is not required and board space permits TO-263 footprint |

FAQ
What is the maximum continuous output current specification for TLV4110IP at 5 V supply?
The TLV4110IP delivers ±320 mA continuous output current at 5 V supply, measured at 0.5 V from the rail. This rating assumes proper thermal management using the MSOP PowerPAD™ package mounted to a PCB with thermal vias to ground. At junction temperatures exceeding 105°C, continuous current must be derated to maintain reliability - e.g., 110 mA max at TJ = 150°C.
Does TLV4110IP support rail-to-rail input voltage range?
No, TLV4110IP does not support rail-to-rail input. Its common-mode input voltage range is specified as 0 V to (VDD − 1.5 V) - meaning at 5 V supply, inputs must stay within 0 V to 3.5 V. However, its output is rail-to-rail, swinging within 0.1 V of both supply rails under 100 mA load, which is critical for maximizing dynamic range in low-voltage systems.
How is the shutdown function implemented on TLV4110IP?
The TLV4110IP features an active-high SHDN pin (Pin 5). To enable the amplifier, SHDN must be pulled to ≥2.1 V (at 3 V supply) or ≥3.8 V (at 5 V supply); to disable, it must be driven ≤0.9 V (at 3 V) or ≤1.65 V (at 5 V). An external pullup resistor is required - floating SHDN may cause unintended shutdown due to leakage. Shutdown reduces supply current to ≤15 µA per channel and places the output in high-impedance state.
Which package type does TLV4110IP use, and why is thermal design critical?
TLV4110IP uses the 8-pin MSOP PowerPAD™ (DGN) package with an exposed thermal pad on the underside. This pad must be soldered to a PCB copper area connected to GND via ≥5 thermal vias (13 mil diameter) to achieve θJA = 52.7°C/W. Without this, thermal resistance rises sharply - SOIC variants have θJA = 176°C/W, limiting continuous power to 350 mW versus >2.3 W for properly mounted DGN - directly impacting sustained output current capability.
Can TLV4110IP drive capacitive loads, and what precautions apply?
TLV4110IP can drive capacitive loads up to 1 nF stably without external compensation. For loads >1 nF, a series "nulling" resistor (RNULL) of ≤20 Ω must be placed between the output (Pin 7) and the load to preserve phase margin and prevent oscillation. This is especially critical in motor driver or relay coil applications where parasitic capacitance may exceed 1 nF - failure to add RNULL risks high-frequency ringing and output stage instability.
