Stereo Audio Taper Potentiometers

with Pushbutton Interface

_______________________________________________________________________________________ 3

Note 1: Parameters are 100% production tested at +85°C and limits through temperature are guaranteed by design.

Note 2: Supply current measured with the supply on and a button pushed.

Note 3: Supply current measured with the power on, no button pushed, and the wiper position fixed.

Note 4: This is the measured current with SHDN low and MODE_IND unconnected.
