The ISL22416 is a single digitally controlled potentiometer with low noise, low power, SPI bus, and 128 taps. It features non-volatile memory and can be used in a wide range of applications including control, parameter adjustments, and signal processing.
The ISL22416 is a single digitally controlled potentiometer (XDCP) that integrates a DCP and non‑volatile memory on a CMOS IC. It can be used as a three‑terminal potentiometer or a two‑terminal variable resistor and is controlled via an SPI serial interface.
Key features include 128 resistor taps, selectable total resistance of 10 kΩ or 50 kΩ, low wiper resistance (70 Ω typical at 3.3 V), and operation over a 2.7 V to 5.5 V supply range. The device is offered in 10‑lead MSOP and 10‑lead TDFN packages and meets RoHS requirements.
