DESCRIPTION
PT2259 is an 8-pin 2-channel volume controller which utilizes CMOS technology and incorporates the
I2C interface control. The controller features an attenuation range of 0 to -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.
