ISL23415TFRUZ-T7A

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 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.

• 256 resistor taps
• SPI serial interface
• Shutdown Mode - forces the DCP into an end-to-end open circuit and RW is shorted to RL internally
• Power-on preset to mid-scale (128 tap position)
• Shutdown and standby current
• Extended industrial temperature range: -40°C to +125°C
• 10 Ld MSOP or 10 Ld µTQFN packages
• Pb-free (RoHS compliant)
