Volume Controller IC
DESCRIPTION
PT2259 is an 8-pin 2-channel volume controller which
utilizes CMOS technology and incorporates the I
2
C
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.
