Product details
Overview
TLV4110ID from Texas Instruments is a single-channel, rail-to-rail output operational amplifier with shutdown control, designed for high-current buffer and coil driver applications. It delivers >300 mA output current at 5 V, features 2.7 MHz unity-gain bandwidth, 1.5 V/µs slew rate, and operates from 2.5 V to 6 V supply across −40°C to 125°C industrial temperature range.
For engineers reviewing the TLV4110ID datasheet, TLV4110ID pinout, TLV4110ID application, or TLV4110ID equivalent, key selection criteria include output drive capability (>300 mA), thermal performance in MSOP PowerPAD package, shutdown functionality, rail-to-rail output swing, and compatibility with low-voltage (2.5 V) systems requiring robust analog buffering.
Technical Context
The TLV4110ID implements a high-output-current CMOS op-amp architecture optimized for driving heavy resistive or inductive loads without external transistors. Its internal design supports fast turn-on/off times (1 µs / 3.3 µs) and maintains stability with capacitive loads up to 1 nF when using recommended RNULL series output resistance.
It integrates a dedicated SHDN terminal that places the amplifier in high-impedance state with only 10 µA typical supply current per channel in shutdown mode. The device's thermal management relies on the MSOP PowerPAD package's low θJA (52.7°C/W) and electrically isolated thermal pad soldered to PCB ground.

Pinout & Package
The TLV4110ID is supplied in an 8-pin MSOP PowerPAD™ package (DGN), featuring an exposed thermal pad on the underside that must be soldered to a PCB ground plane for optimal thermal performance. This thermally enhanced package achieves θJA = 52.7°C/W and supports continuous power dissipation up to 474.4 mW at 125°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |

| 3 (IN+) | Non-inverting input | Differential input node; common-mode range extends from GND to VDD−1.5 V |
| 4 (GND) | Analog ground reference | Primary return path for output current and supply; must connect directly to low-impedance ground plane |
| 5 (SHDN) | Active-high shutdown control | Pulled high (>3.8 V @ 5 V) to enable; pulled low (<1.65 V) to disable amplifier and enter ultra-low-IDD mode |
| 6 (VDD) | Positive supply rail | Accepts 2.5–6 V; absolute max 7 V; PSRR = 70 dB @ 5 V supply |
| 7 (OUT) | Amplifier output | Capable of sourcing/sinking ±320 mA; rail-to-rail swing with <0.55 V VOL @ 100 mA sink |

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 | Higher supply voltage (up to 16 V), lower output current (100 mA), no shutdown pin | Lacks integrated shutdown and thermal enhancement; requires external transistor for >100 mA loads | Select when operating above 6 V or when shutdown is unnecessary and cost is primary constraint |
| OPA547TP | Higher output current (500 mA), wider supply range (8–60 V), TO-220 package | Requires heatsink; larger footprint; no rail-to-rail output; higher quiescent current (10 mA) | Select for high-voltage (>12 V), high-power industrial actuators where PCB space is less constrained |
Compared with TLC071CDR and OPA547TP, the TLV4110ID uniquely combines rail-to-rail output, integrated shutdown, MSOP PowerPAD thermal efficiency, and 320 mA drive in a 2.5–6 V system-making it optimal for space-constrained, battery-sensitive industrial and portable applications.

FAQ
What is the maximum continuous output current specification for TLV4110ID at 125°C ambient?
The TLV4110ID supports 110 mA continuous output current per channel at junction temperature ≤150°C, which corresponds to ~110 mA at 125°C ambient when using the MSOP PowerPAD package with proper PCB thermal design (θJA = 52.7°C/W). This is derived from the absolute maximum ratings table specifying "Continuous/RMS output current: TJ ≤ 150°C → 110 mA".
Does TLV4110ID require external components to drive capacitive loads?
Yes-when driving capacitive loads >1 nF, TLV4110ID requires a series resistor (RNULL) between the output and load to maintain phase margin and prevent oscillation. The datasheet recommends RNULL ≤20 Ω and provides Figure 27(a) as the standard snubber configuration. Without this, ringing or instability may occur due to reduced phase margin.
Is the thermal pad on the TLV4110ID MSOP PowerPAD package electrically connected to any internal circuit?
No-the thermal pad on the TLV4110ID MSOP PowerPAD package is electrically isolated from all internal terminals, as explicitly stated in the "APPLICATION INFORMATION" section (Figure 30 note A). It must be soldered to PCB ground solely for thermal conduction-not for electrical reference or signal return.
Can TLV4110ID operate from a 2.5 V supply while maintaining rail-to-rail output swing?
Yes-TLV4110ID is fully specified down to 2.5 V supply and delivers rail-to-rail output swing. At 2.5 V and 10 mA load, VOH ≥ 2.4 V and VOL ≤ 0.1 V, preserving >95% of full-scale output range. This capability is confirmed in the "electrical characteristics" tables under "output characteristics" with VDD = 2.5–6 V test conditions.
What is the shutdown current consumption of TLV4110ID across its full temperature range?
TLV4110ID draws ≤15 µA per channel in shutdown mode across its full operating temperature range of −40°C to 125°C, as specified in the "shutdown characteristics" table under IDD(SHDN). At 25°C, typical shutdown current is 3.4 µA, enabling ultra-low-power sleep states in portable and energy-harvesting systems.
