Description
The iC-TW11 is a single-chip magnetic rotary encoder for low-voltage (1.8 V – 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 4 mm x 4 mm QFN16 package. Built-in automatic gain control (AGC) assures optimum analog-to-digital conversion under all conditions with no setup. A noise filter improves measurement stability, and can be disabled to reduce power consumption. The iC-TW11 supports a maximum conversion rate of 4 kHz (4000 samples per second) with power consumption proportional to the conversion rate. Low power mode reduces current by a factor of 7 while increasing the maximum sampling rate to 20 kHz. Sampling is initiated over the SPI interface or via a dedicated pin for application versatility. Communication and control of the iC-TW11 is via a 4-wire SPI interface and multiple devices can be chained together for efficient usage. Absolute position angle, angle-equivalent sine and cosine values, and the three raw Hall element voltages can all be read over the SPI interface allowing both simple and sophisticated applications to be implemented easily.
