ISL23415 - Low Voltage Digitally Controlled Potentiometer

Description

VLOGIC SPI bus/logic supply.

Features

  • 256 resistor taps.
  • SPI serial interface - No additional level translator for low bus supply - Daisy Chaining of multiple DCP.
  • Power supply - VCC = 1.7V to 5.5V analog power supply - VLOGIC = 1.2V to 5.5V SPI bus/logic power supply.
  • Wiper resistance: 70 typical @ VCC = 3.3V.
  • 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.

DATASHEET ISL23415 Single, Low Voltage Digitally Controlled Potentiometer (XDCP™) FN7780 Rev.3.00 Mar 17, 2022 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.
