LT-122
2CH SPI Signal Amplifier
LT-122 2CH SPI Signal Amplifier
LT-122 SPI amplifier can realize SPI (TTL) signal’s expansion, amplification and distribution. Especially suitable for multi-
channel sync control projects. It can copy the changes of one channel LEDs to others, so you can connect dozens LEDs than
before by install several signal amplifiers, and save lots of money on the project.
LT-122 SPI signal amplifier is full compatibility. can be used to expand all manufacturers' SPI(TTL) signal controller and
lamp's signal in market. And It can connect with SPI(TTL) signal of all ICs .
