Depop is a real BOM-level win: it eliminates the need for external muting relays or soft-start circuits that add cost and board area. The built-in short-circuit and thermal protection means the amplifier can survive a speaker-wire short during assembly test or field use without latching up or burning the PCB trace. That reduces warranty returns and board-level rework.
No official equivalent or pin-compatible replacement is listed in the manufacturer cross-reference for the TAS5753MDDCAR. For a BOM requiring a second source, review other Class D amplifiers in the same 48-HTSSOP footprint with a 4.5V to 24V supply range, but verify pinout and register map compatibility against the datasheet.
Yes, the TAS5753MDDCAR includes depop circuitry to eliminate power-on/off pops, plus short-circuit and thermal protection for robust operation.
The package is a 48-TFSOP (0.240", 6.10mm Width) with an exposed pad, supplied as a 48-HTSSOP. The exposed pad must be soldered to a PCB thermal land and connected to a ground plane for adequate heat dissipation. Follow the manufacturer's recommended land pattern in the datasheet for the 48-HTSSOP package.
