The ISL23425WFVZ-T7A is a dual, 256-tap, low voltage digitally controlled potentiometer featuring an SPI Bus interface. It operates with a total resistance of 10kOc and is designed for low power consumption, making it suitable for battery-operated devices. Each potentiometer is controlled via a volatile Wiper Register, which allows for direct writing and reading of the wiper position. The device supports a power supply range of 1.7V to 5.5V for analog power and 1.2V to 5.5V for the SPI bus, eliminating the need for additional level translation for low bus supply voltages. The ISL23425WFVZ-T7A includes a shutdown mode that reduces power consumption by disconnecting the potentiometer from the circuit. It has a typical wiper resistance of 70Oc at 3.3V and is designed to operate over an extended temperature range of -40¬8C to +125¬8C. The product is available in a 16-lead ¬µTQFN package and is RoHS compliant. Applications include power supply margining, trimming sensor circuits, and gain adjustments in battery-powered instruments.
The ISL23425 is a volatile, low voltage, low noise, low power, 256-tap, dual digitally controlled potentiometer (DCP) with an SPI Bus™ interface. It integrates two DCP cores, wiper switches and control logic on a monolithic CMOS integrated circuit.brbr Each 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. Each potentiometer has an associated volatile Wiper Register (WRi, i = 0, 1) that can be directly written to and read by the user. The contents of the WRi controls the position of the wiper. When powered on, the wiper of each DCP will always commence at mid-scale (128 tap position).brbr The low voltage, low power consumption, and small package of the ISL23425 make it an ideal choice for use in battery operated equipment. In addition, the ISL23425 has a VsubLOGIC/sub pin allowing down to 1.2V bus operation, independent from the VsubCC/sub value. This allows for low logic levels to be connected directly to the ISL23425 without passing through a voltage level shifter.brbr 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.
