Overview
The TAS2505IRGET is a Class-D audio amplifier manufactured by Texas Instruments, designed for single-channel mono applications. It delivers an output power of 2.6 W into a 4-ohm load with a THD+N of -73.9 dB. The device operates on a supply voltage ranging from 1.5 V to 1.95 V and features analog input with a gain of 4 V/V. Packaged in a 24-VQFN (4x4) format, it supports surface mount installation and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates I2C interface for digital control capabilities including volume adjustment and shutdown modes.
- Includes built-in thermal protection mechanisms to ensure operational safety under varying load conditions.
- Supports analog audio input signals with fixed voltage gain configuration.
Applications
- Single-channel mono headphone amplification
- Embedded audio systems requiring low-voltage operation
- Portable electronic devices utilizing Class-D efficiency
Procurement Notes
Verify the specific suffix IRGET against the manufacturer's current datasheet to confirm package dimensions and pinout compatibility. Ensure that the required operating temperature range aligns with the industrial specification limits defined in the official documentation before finalizing component selection for production.
Selection Notes
Select this component when a single-channel mono Class-D amplifier is required for low-voltage systems. Confirm that the 1.5 V to 1.95 V supply range matches the system design. Verify that the 24-VQFN package fits the available PCB footprint and that the -40°C to +85°C operating range satisfies environmental requirements.
Part Context
This part belongs to the TAS2505 series of audio amplifiers from Texas Instruments. The series includes variants such as TAS2505IRGER and automotive-grade options like TAS2505TRGERQ1. These components share similar core functionalities but differ in qualification standards, packaging, and specific electrical characteristics tailored for different market segments.
Replacement Considerations
TAS2505IRGER is a comparable variant within the same series. Verify if the alternative meets all electrical and thermal specifications. Cross-reference the datasheet to ensure package compatibility and functional equivalence before substitution.
