The ISL23415 is a volatile, low voltage, low noise, low power,
SPI™ bus, 256 taps, single digitally controlled potentiometer
(DCP), which integrates DCP core, wiper switches and control
logic on a monolithic CMOS integrated circuit.
The digitally controlled potentiometer is implemented with a
combination of resistor elements and CMOS switches. The
position of the wipers are controlled by the user through the
SPI bus interface. The potentiometer has an associated
volatile Wiper Register (WR) that can be directly written to and
read by the user. The contents of the WR controls the position
of the wiper. When powered on, the ISL23415’s wiper will
always commence at mid-scale (128 tap position).
The low voltage, low power consumption, and small package
of the ISL23415 make it an ideal choice for use in battery
operated equipment. In addition, the ISL23415 has a VLOGIC
pin allowing down to 1.2V bus operation, independent from the
VCC value. This allows for low logic levels to be connected
directly to the ISL23415 without passing through a voltage
level shifter.
The DCP can be used as a three-terminal potentiometer or as a
two-terminal variable resistor in a wide variety of applications
including control, parameter adjustments, and signal
processing.
Features
• 256 resistor taps
• SPI serial interface
- No additional level translator for low bus supply

circuit and RW is shorted to RL internally
• Power-on preset to mid-scale (128 tap position)
• Shutdown and standby current <2.8µA max
• DCP terminal voltage from 0V to VCC
• 10k 50kor 100ktotal resistance
• Extended industrial temperature range: -40°C to +125°C
• 10 Ld MSOP or 10 Ld µTQFN packages
• Pb-free (RoHS compliant)
Applications
• Power supply margining
• RF power amplifier bias compensation
• LCD bias compensation
• Gain adjustment in battery powered instruments
• Portable medical equipment calibration
