X9409 is a 4-channel digitally controlled potentiometer (XDCP™) from ON Semiconductor, which features 4 potentiometers, 64 resistor taps, 2-wire serial interface, 50Ω wiper resistance, 4 non-volatile data registers, non-volatile storage of multiple wiper position, power-on recall, low standby current, system VCC: 2.7V to 5.5V operation, 10kΩ, 2.5kΩ end to end resistance, 100 yr. data retention, endurance: 100,000 data changes per bit per register, low power CMOS, 24 Ld SOIC, 24 Ld TSSOP, lead-free plus anneal available (RoHS compliant)
The X9409 integrates four digitally controlled potentiometers (XDCP) in a single CMOS microcircuit. Each potentiometer offers 64 resistor taps and can be operated via a 2‑wire serial interface for reading and writing wiper positions and non‑volatile registers.
The device operates from 2.7 V to 5.5 V, features ultra‑low standby current (< 1 pA), and retains data for up to 100 years. It supports power‑on recall, non‑volatile storage of multiple wiper positions, and up to 100 k data changes per bit per register.
