DESCRIPTION
The X9409 integrates 4 digitally controlled potentiometers (XDCP) on a monolithic CMOS integrated microcircuit.

FEATURES
• Four potentiometers per package
• 64 resistor taps
• 2-wire serial interface for write, read, and 
   transfer operations of the potentiometer
• 50Ω Wiper resistance, typical at 5V.
• Four non-volatile data registers for each
   potentiometer
• Non-volatile storage of multiple wiper position
• Power on recall. Loads saved wiper position on
   power up.
• Standby current < 1µA typical
• 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-lead SOIC, 24-lead TSSOP, and
   24-lead CSP (Chip Scale Package) Packages
