Overview
The TAS2505IRGER is a Class-D audio amplifier manufactured by Texas Instruments, designed for single-channel mono applications. It operates within a supply voltage range of 1.5 V to 1.95 V and delivers power into a 4-ohm load. The device features I2C interface capabilities, shutdown mode, thermal protection, and volume control functions. It is housed in a 24-VQFN package with dimensions of 4x4 mm and supports surface mount installation. The operational temperature range extends from -40°C to +85°C.
Feature Summary
- Integrates digital input Class-D amplification technology for speaker driving.
- Includes built-in thermal protection mechanisms to ensure operational safety.
- Supports I2C communication for configuration and volume adjustment.
Applications
- Portable electronic devices requiring compact audio solutions
- Single-speaker systems in consumer electronics
- Battery-powered audio equipment
Procurement Notes
Verify the specific suffix IRGET against datasheet requirements to confirm package type and temperature grade. Ensure compatibility with system voltage limits of 1.5 V to 1.95 V. Confirm moisture sensitivity level handling procedures during assembly. Validate that the 24-VQFN footprint matches the PCB design constraints.
Selection Notes
Select this component for designs requiring a low-voltage, single-channel Class-D amplifier with digital control interfaces. Consider the 24-VQFN package size for space-constrained layouts. Verify that the operating temperature range of -40°C to +85°C meets environmental specifications. Compare against automotive-grade variants if higher temperature ratings are required.
Part Context
This part belongs to the TAS2505 series of audio amplifiers from Texas Instruments. It is distinct from the automotive-qualified TAS2505-Q1 variants, which offer extended temperature ranges and AEC-Q100 certification. The standard industrial version focuses on cost-effective integration for general consumer electronics applications.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate the TAS2505IRGET for identical electrical characteristics and packaging. Assess the TAS2505TRGERQ1 only if automotive qualification and extended temperature range are acceptable alternatives.
