TDA7343D - Brand New STMicroelectronics IC Chips
Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
DESCRIPTION
The TDA7343 is an upgrade of the TDA7313 audioprocessor.
Thanks to the used BIPOLAR/CMOS technology, very low distortion, low noise and
DC-stepping are obtained.
Due to a highly linear signal processing, using CMOS-switching techniques
instead of standard bipolar multipliers, very low distortion and very low
noise are obtained Several new features like softmute, zero-crossing mute and
pause detector are implemented.
The Soft Mute function can be activated in two ways:
1 Via serial bus (bit D0, Mute Byte)
2 Directly on pin 22 through an I/O line of the microcontroller
Very low DC stepping is obtained by use of a BICMOS technology.
