Catalyst CAT5419 Dual Digitally Programmable Potentiometer Datasheet
The CAT5419 is a dual digitally programmable potentiometer (DPP) featuring 64 resistor taps per potentiometer and a 2‑wire serial interface compatible with I2C. It includes four non‑volatile wiper settings, write protection, and up to 100‑year data retention, making it suitable for circuit‑level adjustments.
The device operates from 2.5 V to 6.0 V, provides a standby current of less than 1 µA, and supports up to 1 000 000 write cycles. It can be addressed on a shared bus with up to sixteen devices, and its pins are available in SOIC, TSSOP, and BGA packages.
