概要
説明
The ISL90842 integrates four digitally controlled potentiometers (DCP) configured as variable resistors on a monolithic CMOS integrated circuit. The digitally controlled potentiometers are implemented with a combination of resistor elements and CMOS switches. The position of the wipers are controlled by the user through the I2C bus interface. Each potentiometer has an associated 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. The DCPs can be used as two-terminal variable resistors in a wide variety of applications including control, parameter adjustments, and signal processing.

Processing table
Tips for Using This Parametric Table:
- Hide Filters button in header: Collapse or expands filters
- Column sort buttons in header: Sort Column alphabetically / numerically descending or ascending
- Reset button in header: Reset all filters to the page default
- Full Screen button in header: Expand the table to full screen view (user must close out of full screen before they can interact with rest of page)
- Export button in header: Export the filtered results of the table to an Excel document
- Filter parts search bar in header: Type to filter table results by part number
- Hide column button in column headers: Select to hide columns in table
- AND / OR toggle switches in header: Toggles the logic of this particular filter to be “AND” or “OR” logic for filtering results
- Multiselect checkboxes at beginning of each row in table: Select these checkboxes to compare products against each other
- Document icon next to product name in row: View the featured document for this product
- Chip icon next to the right of the document icon in row: View the block diagram for this product
- Cart icon to the right of the chip icon: Indicates that samples are available for this product
