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.Features- 10-bit angle resolution- Split power supplies for 1.8 V I/O applications- Sampling initiated via SPI command or dedicated pin- typ. 4 kHz maximum sampling frequency- 21 µA typical supply current at 10 Hz sampling frequency- Low power mode reduces current to 3 µA at 10 Hz- Automatic power-down to 100 nA between samples- Standard 4-wire SPI communication- Automatic Hall array gain control (AGC)- Digital filter to reduce measurement noise- Operational temperature range of -40 to +125 °C- Space-saving, RoHS compliant 4x4 mm QFN16 packageApplications- Battery-powered equipment- Digital potentiometers- Front panel controls- Servo or stepper motor control- Assembly robots and autonomous vehicles- Office equipment and household appliances
