The ISL90461 is an Intersil digitally controlled potentiometer (XDCP) that can be configured from 2.7V to 5.5V. It is a variable resistor comprising a resistor array, wiper switches, a control section, and volatile memory. A 2-pin Up/Down interface controls the wiper position. The potentiometer is implemented by a resistor array comprising 31 resistive elements and a wiper switching network. Between each element and at either end there 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 range 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.
The ISL90461 is a volatile solid‑state digital potentiometer (XDCP) that provides 32 wiper tap points and can be configured as a variable resistor. It is controlled via a simple 2‑pin Up/Down interface and includes chip‑select, supply, and ground pins.
The device is offered in SC‑70 and SOT‑23 packages, supports supply voltages from 2.7 V to 5.5 V, and operates over an industrial temperature range of –40 °C to +85 °C. It is RoHS‑compliant and available in several resistance options (10 kΩ, 50 kΩ, 100 kΩ).
