A1330
Programmable Angle Sensor IC
with Analog and PWM Output
FEATURES AND BENEFITS Analog output, configurable to ratiometric or non-ratiometric Contactless 0В° to 360В° angle sensor IC, for angular
position, rotational speed, and direction measurement Single and dual die options available in same package Non-volatile memory (EEPROM) for use in application
trimming/calibration Circular Vertical Hall (CVH) technology provides a
single-channel sensor system with air gap independence 12-bit resolution possible in Low RPM mode, 10-bit
resolution in High RPM mode Angle Refresh Rate (output rate) configurable between
25 and 3200 Вµs through EEPROM programming Customer-programmable output clamp levels provide
short-circuit diagnostic capabilities Open-circuit detection on ground pin (broken wire) Undervoltage lockout for VCC below specification Fine angle scaling for short-stroke applications Missing Magnet Error flag for notifying controller of low
magnetic field level Continued on the next page… PACKAGE: 8-pin TSSOP (LE package) Regulator
Multisegment
CVH Element The A1330 is a 360В° angle sensor IC that provides contactless
high-resolution angular position information based on magnetic
Circular Vertical Hall (CVH) technology. It has a system-onchip (SoC) architecture that includes: a CVH front end, digital
signal processing, and an analog output driver. It also includes
on-chip EEPROM technology, capable of supporting up to
100 read/write cycles, for flexible end-of-line programming
of calibration parameters. Broken ground wire detection and
user-selectable output voltage clamps make the A1330 ideal
for high-reliability applications requiring high-speed 0В° to
360В° angle measurements.
The A1330 provides adjustable internal averaging, allowing …
