TDA7492 High-power Digital Power Amplifier Board 2*50W/100W Parallel Bridge better than TA2024/TA2021
TDA7492 digital amplifier board is the swiss printronix co ltd (STMicroelectronics ) 's TDA7492 for core,high performance! inexpensive , sound quality is very good , analog ic can say is difficult adversary . several hundred lm3886 this unlikelier monophthongs good ! suitable for multimedia , desktop amplifier , etc suitable to be more encoding audio amplifier , play electronic frequency , manufacture subwoofer amplifier , etc power supply simple (DC voltage 10-26V were simlarly ) , the most high power 50W*2/8 ohm,single audio encoding BTL power 100W/4 ohm, measurement of small , 70 * 57mm , highly 21mm ( radiator-fan ) with radiator-fan delivery.
- on-off impact sound very small , almost can ignore !
product features below :
1 , adopts smt high speed mounter smd , too high temperature reflow , very stable performance , handmade welding technology can compare
2 , the 1690s 4 group gain adjust ( batch can provide rem. technology with dissident , one-chip don't how to change the , book plate gain default adjust the biggest )
3 , Volume ultra-small 70x57mm can be used to maintenance , grinding active speaker , monophthongs improve , also can use many form more encoding audio amplifier or 2.1 amplifier , useful many-many
4 , own overdesigned output short circuit and overload protection temperature , and prevent on-off impact , the others in 50w amplifier board is very rare
note : when the speaker impedance is 4 ohm , work voltage must be smaller than 18V ,when the speaker is 6 ohm, work voltage can't more than 24V, when the speaker is 8 ohm, work voltage can't more than 26V , power supply polarity don't reversed
