Overview
The TPA1517DWPRG4 is a stereo audio amplifier manufactured by Texas Instruments, belonging to the TPA1517 series. It operates as a Class-AB amplifier with two output channels. The device delivers up to 6W of output power into an 8-ohm load and features a total harmonic distortion plus noise (THD+N) of 0.1%. It functions on a single power supply ranging from 9.5V to 18V. Key electrical specifications include a gain of 20 dB, a maximum output current of 4 A, and a quiescent operating current of 45 mA. The component is housed in a 20-HSOIC package with exposed pad for surface mount installation.
Feature Summary
- Stereo audio amplification using Class-AB topology
- Integrated thermal protection circuitry
- Built-in mute and standby functionality
Applications
- Speaker systems
- Audio signal processing circuits
Procurement Notes
Verify that the ordering suffix 'G4' corresponds to lead-free and RoHS compliance status as defined by Texas Instruments. Confirm the specific package variant matches the required 20-HSOIC footprint with exposed pad. Ensure the component meets the specified -40°C to +85°C operating temperature range for the intended application environment.
Selection Notes
Select this component when a stereo Class-AB amplifier with high output current capability is required. The 20-HSOIC package suits surface-mount designs needing robust thermal dissipation via the exposed pad. Verify compatibility with single-supply voltages between 9.5V and 18V and ensure the 20 dB fixed gain aligns with system input requirements.
Part Context
This part is a green version of the TPA1517DWPR, adhering to environmental standards. It shares the same functional specifications as the standard TPA1517 series but includes packaging and material modifications to meet regulatory requirements. It is categorized under linear audio amplifiers within the Texas Instruments portfolio.
Replacement Considerations
The TPA1517NE serves as a through-hole alternative within the same family. Direct pin-to-pin replacement requires verifying package compatibility between the HSOIC and other available formats.
