Product details
Overview
TLV4113IDR from Texas Instruments is a dual-channel, rail-to-rail output operational amplifier with shutdown control, delivering >300 mA output current per channel at 5 V, 2.7 MHz unity-gain bandwidth, and 1.5 V/µs slew rate. It operates from 2.5 V to 6 V and supports industrial temperature range (−40°C to 125°C), enabling high-current buffer and coil driver applications in motor control and power management circuits.
For engineers reviewing the TLV4113IDR datasheet, TLV4113IDR pinout, TLV4113IDR application, or TLV4113IDR equivalent, key selection criteria include verified shutdown functionality, thermal performance in MSOP PowerPAD™ package, rail-to-rail output swing under load, and confirmed 300 mA continuous drive capability per channel at 125°C ambient.
Technical Context
The TLV4113IDR integrates two independent high-output-drive op-amps with dedicated shutdown inputs (1SHDN, 2SHDN), enabling independent channel disable. Its architecture supports unity-gain stable operation into capacitive loads up to 1 nF without external compensation, with phase margin ≥66° at 100 pF load.
It features rail-to-rail output swing (within 100 mV of rails at 100 mA), low input offset voltage (max 4 mV), and high PSRR (70 dB at 5 V). Shutdown mode reduces supply current to ≤15 µA per channel while placing outputs in high-impedance state-critical for battery-powered systems requiring dynamic power gating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - enables independent signal conditioning or parallel current boosting in compact space-constrained designs. |
| Output Drive | >300 mA per channel - sufficient to directly drive solenoids, relays, or LED strings without external transistors. |
| Rail-to-Rail Output | Swings within 100 mV of rails at 100 mA - maximizes dynamic range in single-supply 3.3 V or 5 V systems. |
| Unity-Gain Bandwidth | 2.7 MHz - supports closed-loop gain ≥10 up to ~270 kHz with stable phase margin. |
| Slew Rate | 1.5 V/µs - enables clean 100 kHz square-wave output at 1 Vpp into 100 Ω load. |
| Supply Voltage Range | 2.5 V to 6 V - compatible with Li-ion (3.0–4.2 V), USB (5 V), and industrial 3.3 V/5 V rails. |
| Shutdown Current | ≤15 µA per channel - extends battery life in portable instrumentation and sensor nodes. |
Pinout & Package
The TLV4113IDR is packaged in a 10-pin MSOP PowerPAD™ (DGQ) thermally enhanced surface-mount package with exposed thermal pad on underside, optimized for high-current operation and junction temperature control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | High-current rail-to-rail output capable of sourcing/sinking >300 mA; requires thermal pad soldering for full rating. |
| 1IN− | Channel 1 inverting input | Differential input with CMRR ≥63 dB; supports common-mode range from GND to VDD−1.5 V. |
| 1IN+ | Channel 1 non-inverting input | Low bias current (≤500 pA) enables high-impedance sensor interfacing without significant error. |
| GND | Analog ground reference | Must be connected to PCB ground plane; thermal pad is electrically isolated but must connect to GND for thermal conduction. |
| 1SHDN | Channel 1 shutdown control | Active-low logic input; <0.9 V (at 3 V supply) disables amplifier and places 1OUT in high-Z state. |
| VDD+ | Positive supply input | Accepts 2.5–6 V; internal ESD protection rated to ±2 kV HBM; decoupling capacitor required near pin. |
| 2OUT | Channel 2 output | Independent high-current output identical to 1OUT; supports dual-coil or redundant drive configurations. |
| 2IN− | Channel 2 inverting input | Electrically isolated from Channel 1; crosstalk <−60 dB at 100 kHz ensures signal integrity in dual-channel use. |
| 2IN+ | Channel 2 non-inverting input | Matched input characteristics to Channel 1; enables synchronous dual-sensor amplification. |
| 2SHDN | Channel 2 shutdown control | Independent enable/disable control allows staggered power sequencing or fault-isolated channel shutdown. |
Key Features
| Feature | Design Value |
|---|---|
| MSOP PowerPAD™ package | Thermal resistance θJA = 52.3°C/W - enables >2.3 W power dissipation with proper PCB layout, doubling output current vs SOIC. |
| Rail-to-rail output | Delivers 2.6 V swing at 3 V supply and 100 mA load - preserves >85% of full-scale range in low-voltage systems. |
| Independent shutdown | Per-channel SHDN pins allow selective disabling without affecting other channel's bias or output state. |
| High PSRR | 70 dB at 5 V supply - rejects ripple and noise from shared DC-DC converters in mixed-signal PCBs. |
| Low THD+N | 0.035% at 100 Hz, AV=10, RL=100 Ω - suitable for precision analog front-ends in test equipment and audio line drivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-output-drive op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC072CDR | No shutdown function; 100 mA output drive; SOIC-8 only; higher supply current (2.5 mA/ch). | Lacks independent channel disable; unsuitable for battery-critical or thermally constrained designs. | Choose when cost sensitivity outweighs power efficiency and thermal performance requirements. |
| OPA2544TP | Higher output drive (1 A); TO-220 package; no rail-to-rail output; 10× higher quiescent current (7 mA/ch). | Requires heatsink; incompatible with surface-mount-only assembly; limited to 85°C max ambient. | Choose only for legacy designs needing >500 mA drive where PCB real estate and thermal design permit TO-220 mounting. |

FAQ
What is the maximum continuous output current per channel for TLV4113IDR at 125°C ambient?
The TLV4113IDR delivers up to 300 mA per channel continuously at 125°C ambient when mounted on a PCB with properly implemented MSOP PowerPAD™ thermal land pattern (5×13-mil vias to internal GND plane). This rating assumes TJ ≤ 105°C; at TJ = 150°C, continuous current drops to 110 mA per channel per absolute maximum ratings table.
Does TLV4113IDR support rail-to-rail input voltage range?
No, TLV4113IDR does not support rail-to-rail input. Its common-mode input voltage range is specified as 0 V to VDD−1.5 V. At 5 V supply, this permits input signals from 0 V to 3.5 V; at 3.3 V supply, input range is 0 V to 1.8 V. Input voltages beyond this range degrade CMRR and may cause phase reversal.
Can TLV4113IDR drive a 1000 pF capacitive load without oscillation?
TLV4113IDR is unity-gain stable into ≤1 nF capacitive loads only when a series null resistor (RNULL ≤20 Ω) is placed between output and load, as documented in Figure 27 of the datasheet. Without RNULL, phase margin falls below 45° at 100 pF, risking ringing or oscillation in feedback configurations.
What is the recommended PCB layout for TLV4113IDR's PowerPAD™ thermal pad?
The TLV4113IDR DGQ package requires five 13-mil-diameter vias centered under the exposed thermal pad, connected solidly (full circumference plating) to an internal GND plane. Top-side solder mask must expose both leads and thermal pad; bottom-side mask must cover via holes to prevent solder wicking. Thermal pad must be soldered and electrically tied to GND.
How does shutdown functionality affect output state in TLV4113IDR?
When either 1SHDN or 2SHDN is pulled low (<0.9 V at 3 V supply), the corresponding amplifier is disabled and its output enters high-impedance state-neither sourcing nor sinking current. The output remains floating, so external pull-up/down resistors may be needed to define voltage during shutdown. Supply current drops to ≤15 µA per disabled channel.
