... DESCRIPTION PT2259 is an 8-pin 2-channel volume controller which utilizes CMOS technology and incorporates the I interface control. The controller attenuation range -79dB, low noise output, a high degree of stereo separation and requires only a small number of external components. PT2259 is an essential component for modern audio visual systems. ...

... I C BUS INTERFACE In PT2259 the DATA and CLK make up the bus interface through which data is transmitted to and from the microprocessor. DATA VALIDITY Data on the DATA line is considered valid and stable only when the CLK signal is in the “high” state. In addition, the “ ...

... If you do not wish the audio processor (PT2259) to detect the “acknowledge” signal, a simpler microprocessor transmission method can be used: after PT2259 has received a byte wait for one clock pulse and do not acknowledge it. If this approach is used, however, there is a greater chance for faulty operations to occur and noise immunity will be decreased ...
