Procurement Notes
Verify the specific suffix 'DKQ' against the manufacturer's current datasheet to confirm package type and tube packaging details. Ensure compatibility with the required thermal management for the HSSOP-56 package. Confirm that the operating temperature range meets the application requirements. Cross-reference ordering information with official Texas Instruments documentation to avoid discrepancies.
Selection Notes
Select this component when a Class-D amplifier with configurable mono/stereo outputs is required. Consider the HSSOP-56 package size for PCB layout constraints. Verify that the 12V to 36V supply range aligns with the system power design. Evaluate the 0°C to +70°C operating temperature range against environmental conditions.
Part Context
The TAS3251DKQ belongs to the TAS3251 family of audio amplifiers from Texas Instruments. This series includes variants such as the TAS3251DKQR, which shares similar core functionalities but may differ in packaging or reel specifications.
