ISL22414  
FN6424  
Rev 2.00  
September 21, 2015  
Single Digitally Controlled Potentiometer (XDCP™) Low Noise, Low Power, SPI®  
Bus, 256 Taps  
The ISL22414 integrates a single digitally controlled  
potentiometer (DCP), control logic and non-volatile memory  
on a monolithic CMOS integrated circuit.  
Features  
• 256 resistor taps  
• SPI serial interface with write/read capability  
The digitally controlled potentiometer is implemented with a  
combination of resistor elements and CMOS switches. The  
position of the wiper is controlled by the user through the SPI  
serial interface. The potentiometer has an associated  
volatile Wiper Register (WR) and a non-volatile Initial Value  
Register (IVR) that can be directly written to and read by the  
user. The contents of the WR control the position of the  
wiper. At power-up the device recalls the contents of the  
DCP’s IVR to the WR.  
• Daisy Chain Configuration  
• Shutdown mode  
• Non-volatile EEPROM storage of wiper position  
• 14 General Purpose non-volatile registers  
• High reliability  
- Endurance: 1,000,000 data changes per bit per register  
- Register data retention: 50 years @ T 55°C  
• Wiper resistance: 70typical @ 1mA  
• Standby current <2.5µA max  
The ISL22414 also has 14 General Purpose non-volatile  
registers that can be used as storage of lookup table for  
multiple wiper position or any other valuable information.  
The ISL22414 features a dual supply that is beneficial for  
applications requiring a bipolar range for DCP terminals  
between V- and VCC.  
• Shutdown current <2.5µA max  
• Dual power supply  
- VCC = 2.25V to 5.5V  
The DCP can be used as three-terminal potentiometer or as  
two-terminal variable resistor in a wide variety of applications  
including control, parameter adjustments, and signal  
processing.  
- V- = -2.25V to -5.5V  
• 10k 50kor 100ktotal resistance  
• Extended industrial temperature range: -40°C to +125°C  
• Military temperature range: -55 to +125°C  
• 10 Lead MSOP
