The ISL90810 is a single digitally controlled potentiometer (XDCP™) from ISL. It features low noise, low power consumption, I2C bus and 256 taps. The product can be used in a variety of applications including control, parameter adjustments and signal processing.
The ISL90810 is a monolithic CMOS integrated circuit that provides one digitally controlled potentiometer (XDCP) with 256 resistor taps. The wiper position is set via an I²C serial interface and defaults to the mid‑scale (128‑tap) position on power‑up.
The device operates from 2.7 V to 5.5 V, draws a standby current of up to 5 µA, and is offered in an 8‑lead MSOP package. Electrical specifications include a typical wiper resistance of 70 Ω at 3.3 V, total resistance options of 10 kΩ, 50 kΩ, and 100 kΩ, and an operating temperature range from –40 °C to +85 °C (up to +105 °C for some variants).
