TLV4113CD - Dual High-Drive R-R Op Amp | Texas Instruments
MPN: TLV4113CD ✓ Hoạt độngTLV4113CD Tóm tắt
An operational amplifier, commonly shortened to op amp, is an analog signal-conditioning semiconductor that amplifies the voltage difference between its differential inputs. The TLV4113 belongs to the operational-amplifier family, amplifier IC category, and broader analog semiconductor hierarchy. Rail-to-rail output allows the output voltage to approach the positive and negative supply limits, while the shutdown function can place the device into a low-power state when the application no longer requires active operation.
Key features include two amplifier channels in one package, shutdown support, output currents in excess of 300 mA at 5 V, and a standard 14-SOIC footprint. The 2.7 MHz unity-gain bandwidth supports higher-frequency signal paths than a low-bandwidth precision or micropower amplifier. Its 0.55 V/µs minimum slew rate improves large-signal response, while 63 dB nominal common-mode rejection helps attenuate signals common to both inputs.
The high-drive architecture is the central technical distinction of the TLV4113 family. According to the Texas Instruments TLV4113 product page, the amplifiers can source or sink more than 300 mA at 5 V, allowing standard op-amp pinouts to serve as high-current buffers or in coil-driver applications. This drive capability supports low-impedance loads without requiring an external output stage, although sustained high current increases power dissipation and requires careful PCB thermal design.
Typical uses include audio output stages, low-impedance buffers, transducer drivers, relay or solenoid interfaces, and industrial control-signal conditioning. The device is particularly relevant when a conventional dual op amp lacks the current capability to drive a load directly. Shutdown can also reduce consumption in intermittently operating systems, provided the shutdown logic and timing are checked against the device requirements.
For PCB design, use a solid ground return, place input and decoupling capacitors close to their associated pins, and preserve adequate copper around the package for thermal dissipation. Verify output-current limits, supply voltage, load transients, and stability with the selected feedback network. Because output drive is a core feature rather than an incidental specification, calculate worst-case dissipation before assigning the amplifier to a continuous-load position.
This page combines the manufacturer's functional description with verified package and parametric details, application guidance, engineering design notes, and strictly same-package replacement information. It is intended to support faster part selection while keeping package, electrical, sourcing, and lifecycle checks explicit.

Ứng dụng tiêu biểu
TLV4113CD phù hợp cho 6 Áp dụngs: Audio Output Buffer, Coil Driver Interface, Low-Impedance Signal Buffer, Industrial Sensor Conditioning, Relay and Solenoid Interface, Portable Test and Measurement Front End.
Audio Output Buffer
The TLV4113CD fits audio output buffering because it combines rail-to-rail output with more than 300 mA of output current at 5 V. This allows the amplifier to drive a lower-impedance transducer or output stage more effectively than a conventional low-power dual operational amplifier. Its 2.7 MHz nominal unity-gain bandwidth supports audio-band signal amplification, while the 0.55 V/µs minimum slew rate improves large-signal response. The circuit should use negative feedback appropriate for the load, and the designer must verify output swing, distortion, stability, and thermal rise at the highest expected current. Sustained near-limit loading is not implied by the 300 mA performance point and should be treated as a separate worst-case condition.
Được đề xuất
Coil Driver Interface
The TLV4113CD is suitable for driving a coil when the load current remains inside the device’s verified limits. Texas Instruments identifies output current above 300 mA at 5 V as a family capability suitable for coil-driver applications, allowing the operational amplifier to replace a design that would otherwise need an external output stage. The amplifier is used as a closed-loop current or voltage driver, with the feedback network selected for the coil and supply configuration. A flyback diode or other appropriate recirculation path is essential because inductive current continues when the switch opens. Check peak coil current, output voltage swing, repetition rate, and package dissipation rather than relying only on the nominal current statement.

Low-Impedance Signal Buffer
The TLV4113CD can serve as a low-impedance signal buffer where the source has limited current capability. Its high-drive output stage can source or sink more than 300 mA at 5 V, while the 2.7 MHz nominal unity-gain bandwidth provides substantially more signal-path bandwidth than a slow micropower buffer. Configure the device as a voltage follower only after confirming that the selected package and feedback arrangement support the intended load. Stability can change with capacitive loading, so keep signal traces short, place the feedback divider or connection close to the amplifier, and evaluate the worst-case load with an oscilloscope. Thermal analysis should account for the actual voltage drop across the output stage at maximum load current.

Industrial Sensor Conditioning
The TLV4113CD is appropriate for sensor-conditioning stages that require a low-output-impedance analog signal path and occasional load current. The dual configuration places two amplifier channels in one 14-SOIC package, while the 63 dB nominal common-mode rejection ratio helps reject common-mode noise present on sensor inputs. Its 4000 µV maximum input offset voltage should be included in the error budget for sensors with small output ranges. For industrial deployments, select the temperature grade that covers the required ambient and enclosure temperatures. Place input components close to the pins, maintain a low-impedance ground reference, and avoid routing sensitive sensor signals beside high-current output paths to reduce coupled noise.
Được đề xuất
Relay and Solenoid Interface
The TLV4113CD can support relay or solenoid interfaces when its output-drive capability matches the load and its shutdown behavior is useful for intermittent operation. More than 300 mA of output current at 5 V provides margin for compatible loads, while the dual channels permit complementary or separately controlled drive functions. Because inductive loads produce large reverse voltage when de-energized, use an approved flyback clamp and place it close to the load and supply return. The control logic must not exceed the amplifier’s input and shutdown thresholds, and the selected output polarity must remain within the device’s voltage limits. Continuous current and repetitive switching require separate thermal verification.
Được đề xuất
Portable Test and Measurement Front End
The TLV4113CD fits portable instrumentation front ends that need to buffer sensors into a downstream converter or measurement ADC. The 2.7 MHz nominal unity-gain bandwidth can accommodate many higher-frequency analog paths, and the rail-to-rail output helps use the available supply range. The shutdown function can reduce activity when measurements are not being acquired, although timing and logic levels must follow the manufacturer requirements. Because portable equipment can impose strict power limits, calculate the actual dissipation using the measured output voltage rather than the full supply voltage. The 14-SOIC package also requires careful grounding and decoupling to prevent output-drive transients from corrupting the low-level input measurement.

Ghi chú thiết kế
Estimated: output-stage dissipation is P = (VIN − VOUT) × IOUT. At a 5 V supply, 3 V output, and 300 mA load, the estimated amplifier dissipation is 0.6 W; add quiescent current to obtain total device power. This calculation is not a datasheet rating. Calculate dissipation at the highest sustained load and voltage difference, then check the selected package’s thermal limits and PCB copper area. A 14-SOIC footprint benefits from uninterrupted ground-plane copper and short thermal paths to the board structure.
Place input components, feedback elements, and bypass capacitors close to the associated amplifier pins. Keep the high-current output route short and pair it with a low-impedance ground return to limit voltage drops and switching noise. Avoid routing sensitive input traces beneath or beside output and load-current paths. The manufacturer’s recommended component placement and pin table should be followed because the shutdown connection and both channels must be assigned exactly as shown for the 14-SOIC package.
Do not treat the greater-than-300-mA output-current statement at 5 V as permission to operate continuously at the limit. Verify output-current capability across the actual supply voltage, load, output swing, junction temperature, and package limitations. For inductive loads, include an appropriate flyback clamp and check its reverse-energy rating. Also confirm that the feedback network remains stable with the intended capacitive and inductive loading before increasing drive or changing the operating supply.
Although the TLV4113CD has a 2.7 MHz nominal unity-gain bandwidth, the usable signal bandwidth depends on closed-loop gain, load, supply, and feedback impedance. Keep the non-inverting and inverting paths short, minimize parasitic capacitance, and avoid sharing high-impedance input nodes with test points unless their loading has been evaluated. For high-speed or high-current edges, use a ground reference that permits the output current to return without sharing a narrow path with sensitive input circuitry.
