TAS5112DFD Equivalent & Substitute Parts

Part Overview

The TAS5112DFD is a Class D stereo amplifier IC manufactured by Texas Instruments, designed for 2-channel audio amplification applications. This device delivers 62W per channel at 6Ω load impedance and operates across a 16V to 25.5V supply voltage range. The TAS5112DFD is classified as an obsolete product, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. The part integrates digital audio inputs, mute control, short-circuit protection, thermal protection, and shutdown functionality within a 56-HTSSOP surface-mount package.

Engineering Selection Recommendations

The TAS5112ADFD is the direct substitute for the obsolete TAS5112DFD. Both parts are manufactured by Texas Instruments within the PurePath Digital™ series and maintain identical electrical and mechanical specifications across all critical parameters.

Selection Basis:

The TAS5112ADFD is classified as an active product, ensuring continued manufacturing support, availability, and supply chain reliability. This status directly addresses the obsolescence of the TAS5112DFD.

Both parts carry ROHS3 compliance certification and MSL 3 rating, meeting identical environmental and regulatory requirements. The 56-PowerTSSOP package geometry is identical, permitting direct PCB layout compatibility without redesign.

Electrical performance is equivalent: 62W per channel at 6Ω load, 16V to 25.5V supply operation, and identical feature integration (digital inputs, mute, protection circuits, shutdown).

The TAS5112ADFD is supplied in Tube packaging, which may differ from the original TAS5112DFD packaging specification. Verify packaging requirements for your procurement and assembly processes.
