ISL22416 is a single digitally controlled potentiometer from ISL with 128 resistor taps. It can be controlled by the user through the SPI serial interface. The DCP can be used as a three-terminal potentiometer or as a two-terminal variable resistor in a wide variety of applications including control, parameter adjustments, and signal processing.
The ISL22416 integrates a single digitally controlled potentiometer (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, a supply range of 2.7 V to 5.5 V, shutdown mode with 54 µA max current, and RoHS‑compliant Pb‑free packaging in 10‑lead MSOP or TDFN packages.
