ok,

tripath released a relatively new amplifier IC that requires a single supply voltage yet is able to produce a relatively high output compared to other typical single supply amps.

they claim it will output 50watts RMS @ 10% THD (4ohm load and 20Volt supply voltage).

i took a look at the spec sheets... when using 14.4Volts(for automotive applications), it is able to output aprox 20watts RMS @ 1% distortion. anything under 20watts has a much lower distortion of 0.04% and anything higher than 20watts has much more than 1% THD. at 10% THD, output is around 27watts. frequency used for testing is 1khz.

so the chip doesn't seem to be exactly what it was hyped to be but still looks pretty good compared to typical IC amplifiers found in HU's. ( typical HU amps will reach 1% THD at around 12watts RMS(4ohm load) and 23watts RMS @10% THD.)

panasonic has already implemtented the tripath chip in their MXE CQ-C9800U. they claimed 60watts rms but i'm almost sure the specs are still overated. from looking at the datasheets, if panasonic somehow managed to make the amplifier IC's supply voltage 20V, it'll still max out at 50watts RMS @ 10% THD. at more realistic maximum distortion levels, it should be able to do 40watts RMS @ 1% THD if the chip's supply voltage was 20volts. now if panasonic counldn't boost the source voltage to 20volts, but the IC amp in the Panasonic deck is still getting only 14.4V battery voltage, max output will be aprox. 27watts RMS @10%THD and 20watts RMS @ 1% THD. still quite a bit better than the typical deck but not what it's hyped up to be.


so what do you peeps think? did panasonic make the IC supply voltage 20v?

btw, here's the datasheet...

Tripath hasn't released their chips to anyone yet...but i'd buy the stock now while its relatively cheap....Motorola, Panasonic and other companys have jumped on the bandwagon already....its going to be successful!
