ISL90462数据手册集成电路（IC）的数字电位计规格书PDF

描述 Description

The Intersil ISL90462 is a digitally controlled potentiometer (XDCP). Configured as a variable resistor, the device consists of a resistor array, wiper switches, a control section, and volatile memory. The wiper position is controlled by a 2- pin Up /Down interface.
The potentiometer is implemented by a resistor array composed of 31 resistive elements and a wiper switching network. Between each element and at either end are tap points accessible to the wiper terminal. The position of the wiper element is controlled by the CS and U/D inputs. The device can be used in a wide variety of applications including: •LCD contrast control
•Parameter and bias adjustments
•Industrial and Automotive Control
•Transducer adjustment of pressure, temperature, position, chemical, and optical sensors
•Laser Diode driver biasing
•Gain control and offset adjustment
