iC-TW11 is a single-chip magnetic rotary encoder for low voltage
(1.8–3.3 V) and low-power end-of-shaft applications. It
includes three Hall elements, automatic power management
features, and offers 10-bit resolution in a space-saving 4x4 mm
QFN package with 16 pins.
Communication and control of the iC-TW11 is via a 4-wire SPI interface. Multiple devices can be chained together.
