Description
The WSI57C291B-45T is an electronic component model in the IC Chips product category. The WSI57C291B-45T integrates two nonvolatile E2POT™ digitally controlled potentiometers on a monolithic CMOS microcircuit. It features a two-wire serial interface and a register-oriented format, allowing for direct write and read of wiper position. The WSI57C291B-45T also has low power CMOS, a direct write cell with endurance of 100,000 writes per register, and register data retention of 100 years. It comes in 20-lead plastic DIP and 20-lead SOIC packages.
