ISL22102IR20Z - Renesas Electronics

Description: The ISL22102 integrates two digitally controlled potentiometers (DCP) with buffered wiper outputs and an internal bias voltage generator (VB) on a monolithic CMOS integrated circuit. The wiper position is adjusted by the user through simple Up and Down push buttons, ideal for stereo volume control in audio applications. Each potentiometer is implemented using 31 polysilicon resistors in a logarithmic array. Between each of the resistors are tap points connected to the wiper terminal through switches. When p
