TPA3116D2EVM: 50W x 2 @ 4Ω, 6 ~ 26V in, Class D


The TPA3116D2EVM evaluation module (EVM) demonstrates the TPA3116D2 integrated circuit from Texas Instruments (TI).

The TPA3116D2 is a 50-W (per channel), efficient, stereo, digital-amplifier power stage for driving two bridge-tied speakers or a single parallel bridge-tied load. The TPA3116D2 can drive a speaker with an impedance as low as 3.2 Ω (4 Ω typical).

The TPA3116D2 is available in a 32-pin TSSOP.

This document covers EVM specifications and design documentation that includes schematics, bill of materials, and layout design.
