TICore260BTL TPA3251 non-PFFB BTL Stereo 36V (Partial Kit) Amplifier Module
Uses Infineon's OptiReg TLS205B0 24 µVRMS, 500mA linear post regulator for 12V supply, which produces clean and quiet power for the input opamps and low noise floor for a TPA3251 based module.
Designed for use with Coilcraft VER2923-682KL flat wire (not included), low loss inductors to get the most out of the TPA3251's THD+N performance. The output inductors run cool and dissipate very little heat on idle.
The analog input can accept full balanced or single ended signals which can be configured by a solder jumper under the PCB. The output is 2 channel, stereo BTL configuration.
A separate voltage supervisor IC is used to mute the amp in power on, and power off.
Use of oversized capacitors and resistors for the zobel network to ensure reliable operation and better sound quality.
1 pc stereo BTL non-PFFB partial module.
