TPA3116 Datasheet PDF – Class-D Stereo Amplifier, 32 Pin

Part Number: TPA3116, TPA3116D2

Function: Class-D Stereo Amplifier Family With AM Avoidance

Package: HTSSOP 32 Pin Type

Manufacturer: Texas Instruments




The TPA3116 series are stereo efficient, digital amplifier power stage for driving speakers up to 100 W / 2 Ω in mono. The high efficiency of the TPA3130D2 allows it to do 2 × 15 W without external heat sink on a single layer PCB. The TPA3118D2 can even run 2 × 30 W / 8 Ω without heat sink on a dual layer PCB. If even higher power is needed the TPA3116D2 does 2 × 50 W / 4 Ω 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.



1. Supports Multiple Output Configurations

(1) 2 × 50 W Into a 4-Ω BTL Load at 21 V (TPA3116D2)
(2) 2 × 30 W Into a 8-Ω BTL Load at 24 V (TPA3118D2)
(3) 2 × 15 W Into a 8-Ω BTL Load at 15 V (TPA3130D2)

2. Wide Voltage Range: 4.5 V to 26 V

3. Efficient Class-D Operation

(1) >90% Power Efficiency Combined With Low Idle Loss Greatly Reduces Heat Sink Size
(2) Advanced Modulation Schemes

3. Multiple Switching Frequencies

(1) AM Avoidance
(2) Master and Slave Synchronization
(3) Up to 1.2-MHz Switching Frequency
