Part Number : TPA3118D2
Function : 30W, Filter-Free Class-D Stereo Amplifier Family with AM Avoidance
Package : HTSSOP 32 Pin type
Maker : Texas Instruments
Pinouts : 
Description :
The TPA31xxD2 series are stereo efficient, digital amplifier power stage for driving speakers up to 100W/2Ω in mono. The high efficiency of the TPA3130D2 allows it to do 2x15W without external heat sink on a single layer PCB.
The TPA3118D2 can even run 2x30W/8Ω without heat sink on a dual layer PCB. If even higher power is needed the TPA3116D2 does 2x50W/4Ω with a small heat-sink attached to its top side PowerPad. All three devices share the same footprint enabling a single PCB to be used across different power levels.
