It integrates I²C control for volume adjustment, a shutdown pin for power saving, and thermal protection. The 24-VQFN package with exposed pad (4x4 mm) is surface-mount and hand-solderable with care — a fine-tip iron and flux work, but a hot-air station is cleaner for the pad. This part is aimed at portable or battery-powered audio gear — think Bluetooth speakers, soundbars, or handheld radios — where efficiency and small footprint matter. ## Output power and load considerations Rated at 2W into 4Ω, this is a modest output — enough for a small speaker in a portable device. The Class D topology keeps efficiency high, so heat dissipation in the 4x4 mm QFN is manageable with the exposed pad soldered to a ground plane. No external output filter is required for typical speaker loads; the modulation scheme is designed for direct speaker drive. If you're driving a piezo tweeter or long cable runs, add a ferrite bead and a small capacitor to suppress EMI. The thermal protection circuit shuts down the output if the die exceeds the safe limit, so a dead-shorted speaker won't destroy the part — it'll cycle until the fault clears.","metaTitle":"TAS2505IRGET Class D Audio Amplifier, 2W Mono, 24-VQFN","metaDescription":"TI TAS2505IRGET Class D audio amp delivers 2W into 4Ω mono, I²C control, 1.5V–1.95V supply, -40°C to 85°C.

That's the maximum rated output; real-world level depends on supply voltage and speaker impedance."},{"question":"Does TAS2505IRGET require an external output filter?","answer":"No. The Class D output is designed to drive a speaker directly without a filter. For long cable runs or EMI-sensitive applications, a small ferrite bead and capacitor are recommended."},{"question":"What are the alternatives to TAS2505IRGET?","answer":"Within the TAS2505 family, other variants offer different output power levels but share the same 24-VQFN footprint and I²C interface. No pin-compatible second source from another manufacturer is documented."},{"question":"Is TAS2505IRGET compatible with 3.3V logic?","answer":"The I²C and shutdown pins are 1.8V-tolerant only. For 3.3V logic, use a level shifter on SDA, SCL, and the shutdown line."},{"question":"How to connect TAS2505IRGET to an I2C bus?","answer":"Connect SDA and SCL to the 1.8V bus through pull-up resistors (typically 2.2kΩ to 4.7kΩ). The device address is set by the ADR pin; leave it floating or tie to GND for the default address. Ensure the bus voltage doesn't exceed 1.95V."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TAS2505IRGET","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TAS2505IRGET when reusing this data.
