iC-TW11

10-Bit Ultra Low Power Magnetic Absolute Rotary Encoder

Logo iC-TW11

Product description

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 package

Applications
- Battery-powered equipment
- Digital potentiometers
- Front panel controls
- Servo or stepper motor control
- Assembly robots and autonomous vehicles
- Office equipment and household appliances
