Application Scenarios & Design Considerations

4-Channel Automotive Digital Amplifiers 36-HSSOP -40 to 105

Alternative Part Number

  • TAS5424ATDKDMQ1 --: Same TAS54xx family 4-channel Class-D automotive amplifier in the same HTSSOP-44 (DK) package with similar pinout and supply requirements, making it a close functional substitute.
  • TAS5414BTDKDMQ1 --: Updated B-version of the same 4-channel automotive Class-D amplifier in the identical DK package, offering improved performance while remaining pin-compatible with the A-version.
  • TDA7850 --: Widely used 4-channel Class-AB automotive audio amplifier with comparable output power and supply range; a practical cross-vendor alternative when Class-D is not mandatory.
