PT2259 Volume Controller IC
DESCRIPTION PT2259 is an8-pin 2-channel volume controller which utilizes CMOStechnology and incorporates the I2Cinterfacecontrol. The controller features an attenuation range of 0 to-79dB, low noise output, a high degree of stereoseparation and requires only a small number of externalcomponents. PT2259 is an essential component formodern audio visual systems.
