DATASHEET X9511 FN8205 Rev 3.00 Single Push Button Controlled Potentiometer (XDCP) Linear, 32 Taps, Push February 2, 2007 Button Controlled, Terminal Voltage 5V FEATURES DESCRIPTION Push button controlled The Intersil X9511 is a push button controlled potenti- Low power CMOS ometer that is ideal for push button controlled resis- Active current, 3mA max tance trimming. Standby current, 100A typical The X9511 is a resistor array composed of 31 resistive 31 resistive elements elements. Between each element and at either end Temperature compensated are tap points accessible to the wiper element. The 20% end to end resistance range position of the wiper element is controlled by the PU -5V to +5V range and PD inputs. The position of the wiper can be auto- 32 wiper tap points 2 matically stored in E memory and then be recalled Wiper positioned via two push button inputs upon a subsequent power-on operation. Slow and fast scan modes AUTOSTORE option The resolution of the X9511 is equal to the maximum Manual store option resistance value divided by 31. As an example, for the Wiper position stored in nonvolatile memory X9511W (10k ) each tap point represents 323 . and recalled on power-up All Intersil nonvolatile products are designed and 100 year wiper position data retention tested for applications requiring extended endurance X9511W = 10k and data retention.

Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020. *AddT1 suffix for tape and reel. **AddT2 suffix for tape and reel. ***Pb-free PDIPs can be used for through hole wave solder processing only. They are not intended for use in Reflow solder processing applications.
