Application Scenarios & Design Considerations

TDA8944AJ; 2 x 7 W BTL audio amplifier with DC gain control

Alternative Part Number

  • TDA8944J/N2 --: Same TDA8944J audio amplifier family from the successor of Philips Semiconductors, with matching pinout and function; the 'A' variant differs mainly in package/thermal details, so this is the closest drop-in option.
  • TDA8946J --: Similar 2x15W class-AB audio power amplifier in the same TDA894x family with compatible supply voltage and application circuit, usable when slightly higher output power is acceptable.
  • TDA8943AJ --: Lower-power sibling in the same TDA894x BTL audio amplifier series with comparable control and mute/standby interface, suitable as a functional substitute in less demanding designs.
