Product details
Overview
TLV4113CDGQ 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, 1.5 V/µs slew rate, and operating from 2.5 V to 6 V supply. It is designed for high-current buffer and coil driver applications in portable instrumentation and industrial sensing systems.
For engineers reviewing the TLV4113CDGQ datasheet, TLV4113CDGQ pinout, TLV4113CDGQ application, or TLV4113CDGQ equivalent, key selection criteria include its MSOP-10 PowerPAD™ thermal performance, dual-channel shutdown capability, ±320 mA output drive at 5 V, rail-to-rail output swing, and specified operation from 0°C to 70°C (Commercial grade).
Technical Context
The TLV4113CDGQ integrates two independent high-output-drive op-amps with individual shutdown inputs (1SHDN, 2SHDN), enabling selective channel disable. Its internal architecture supports rail-to-rail output swing while maintaining stability into 100 Ω loads and capacitive loads up to 1 nF (with RNULL compensation).
It features low input bias current (≤100 pA), 63–68 dB CMRR, 700 µA per-channel quiescent current, and fast enable/disable timing (1 µs turn-on, 3.3 µs turn-off). The MSOP-10 PowerPAD™ package provides θJA = 52.3°C/W and supports continuous 350 mA per channel at TJ ≤ 105°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - enables independent signal conditioning paths with separate shutdown control per channel. |
| Output Drive | >300 mA per channel at 5 V - sufficient for driving solenoids, relays, or low-impedance transducers without external buffers. |
| Rail-to-Rail Output | Swings within 100 mV of rails at 100 mA load - maximizes dynamic range in single-supply 3 V or 5 V systems. |
| Unity-Gain Bandwidth | 2.7 MHz - supports stable closed-loop operation up to ~200 kHz with moderate gain and low phase margin degradation. |
| Slew Rate | 1.5 V/µs - enables clean 100 kHz sine-wave output at 1 VPP without distortion under 100 Ω load. |
| Supply Voltage Range | 2.5 V to 6 V - compatible with Li-ion (3.7 V), USB (5 V), and dual-cell alkaline (3 V) power rails. |
| Shutdown Current | 3.4 µA per channel - reduces system standby power in battery-operated devices with infrequent wake cycles. |
Pinout & Package
TLV4113CDGQ is housed in a 10-pin MSOP PowerPAD™ package with exposed thermal pad on underside (electrically isolated, must be connected to GND). This thermally enhanced construction enables high-current operation without external heatsinking when PCB layout follows TI's recommended thermal land pattern.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | Delivers high-current buffered signal; capable of sourcing/sinking ±320 mA at 5 V with proper thermal design. |
| 1IN− | Channel 1 inverting input | Differential input node; supports common-mode range from GND to VDD − 1.5 V. |
| 1IN+ | Channel 1 non-inverting input | Differential input node; matched offset and bias characteristics with 1IN−. |
| GND | Analog ground reference | Primary return path for supply and signal currents; also connects thermal pad for heat dissipation. |
| 1SHDN | Channel 1 shutdown control | Active-low logic input; pulls channel 1 output to high-Z and reduces IDD to <15 µA when driven <0.9 V at 3 V supply. |
| VDD+ | Positive supply rail | Single positive supply input (2.5–6 V); powers both channels and internal bias circuitry. |
| 2OUT | Channel 2 output | Independent high-current output; electrically identical to 1OUT with separate shutdown control. |
| 2IN− | Channel 2 inverting input | Second differential pair input; fully isolated from Channel 1 except shared supply and ground. |
| 2IN+ | Channel 2 non-inverting input | Second differential pair input; matches 2IN− in offset and bias performance. |
| 2SHDN | Channel 2 shutdown control | Active-low logic input; independently disables Channel 2 without affecting Channel 1 operation. |
Key Features
| Feature | Design Value |
|---|---|
| High-output-drive capability | ±320 mA per channel at 5 V - eliminates need for discrete output transistors in actuator interfaces. |
| Thermally enhanced MSOP-10 PowerPAD™ | θJA = 52.3°C/W - enables 2.39 W power dissipation at TA = 25°C, supporting sustained high-current operation. |
| Individual channel shutdown | Two dedicated SHDN pins (1SHDN, 2SHDN) - allows dynamic power gating of each amplifier for multi-mode system control. |
| Rail-to-rail output swing | Within 100 mV of rails at 100 mA - preserves full signal headroom in low-voltage data acquisition front-ends. |
| Low quiescent current | 700 µA per channel active, 3.4 µA per channel in shutdown - extends battery life in portable medical or sensor nodes. |
| Stable into capacitive loads | Phase margin ≥66° with 10 pF load - supports direct connection to ADC input caps or long cables without oscillation. |

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 |
|---|---|---|---|
| OPA2544TJ | Higher output current (±500 mA), wider supply (±15 V to ±30 V), SOIC-16 package, no shutdown. | Designed for bipolar high-voltage industrial drivers; lacks shutdown and single-supply rail-to-rail output. | Choose OPA2544TJ only if bipolar supplies and >400 mA drive are required; TLV4113CDGQ preferred for compact 3–5 V portable designs with power gating. |
| TPS54202HDDCR | Not an op-amp - it is a 2-A synchronous buck converter with integrated FETs and enable pin. | Power regulation IC, not signal amplification; functionally incompatible for analog buffering or driver roles. | Not a functional alternative; TLV4113CDGQ serves analog signal path functions, while TPS54202HDDCR regulates power rails. |
Compared with OPA2544TJ and TPS54202HDDCR, TLV4113CDGQ uniquely combines dual-channel rail-to-rail output, per-channel shutdown, MSOP-10 thermal efficiency, and 300+ mA drive in a single-supply 2.5–6 V interface - making it optimal for space-constrained, battery-sensitive analog output stages where discrete power gating and minimal PCB area are critical.

FAQ
What is the maximum continuous output current per channel for TLV4113CDGQ at 5 V supply?
The TLV4113CDGQ delivers ±320 mA per channel at 5 V supply under typical conditions (25°C, VDD = 5 V). Continuous operation at this level requires the MSOP-10 PowerPAD™ package mounted per TI's thermal guidelines to maintain junction temperature ≤105°C. At TJ = 150°C, max continuous current drops to 110 mA per channel.
Does TLV4113CDGQ support rail-to-rail input voltage range?
No, TLV4113CDGQ does not support rail-to-rail input. Its common-mode input voltage range is specified as 0 V to VDD − 1.5 V. For example, at VDD = 5 V, valid input range is 0 V to 3.5 V. Input signals beyond this range may cause increased offset or phase reversal.
How is the thermal pad of TLV4113CDGQ connected in PCB layout?
The exposed thermal pad on the underside of the TLV4113CDGQ MSOP-10 package must be soldered to a PCB copper area tied to GND. TI recommends five 13-mil vias under the pad connected solidly (full circumference, no spokes) to an internal GND plane. This achieves θJA = 52.3°C/W and enables safe 2.39 W dissipation at 25°C ambient.
Can TLV4113CDGQ drive a 100 Ω load stably at unity gain?
Yes, TLV4113CDGQ is characterized for unity-gain stability into 100 Ω resistive loads with 10 pF capacitive load, delivering 66° phase margin and 16 dB gain margin. For heavier capacitive loads (>1 nF), TI recommends adding a 20 Ω series resistor (RNULL) between output and load to preserve stability.
What is the shutdown behavior of TLV4113CDGQ outputs?
When either 1SHDN or 2SHDN is pulled low (<0.9 V at 3 V supply), the corresponding amplifier output enters high-impedance state (not clamped), supply current drops to ≤15 µA per channel, and internal bias circuitry disables. Outputs remain floating - external pull-downs or clamps may be needed for defined idle-state voltage.
