Pt2258 Ic Circuit Diagram. 3 input microphone preamplifier the op amp used here is the ic lm348 due to its unique properties like high gain internally compensated quad operational amplifier with a class ab output stage low input supply drain current and so on. Ptc alldatasheet datasheet datasheet search site for electronic components and semiconductors integrated circuits diodes triacs and other semiconductors.
Pt2258 provides an i2c control interface an attenuation range of 0 to 79db at 1db ste p low noise and high channel separation. The circuit description and diagram is available in the main article. As i have mentioned earlier the pt2258 is an ic made to use as a 6 channel electronic volume controller this ic uses cmos technology specially designed for multi channel audio video applications.
This ic provides an i2c control interface with an attenuation range of 0 to 79db at 1db step and comes in a 20 pin dip or sop package.
