Product Summary

The AD7525U005 is a monolithic CMOS 3 1/2 digit BCD digitally controlled potentiometer designed for precision incremental voltage-divider applications. With the addition of an external op amp, the output of the AD7525U005 can be digitally controlled from 0 to 1.999 Vin with resolution of 0.001 Vin. AC or DC voltage up to ±10V can be applied to the input providing high application flexibility in field such as audio gain control, etc.
