Allegro's A1330 devices feature a system-on-a-chip (SoC) architecture that includes a CVH front end, digital signal processing, and an analog or digital PWM output signal.
The devices are offered in single- and dual-pill versions for systems requiring redundant sensors. They also include on-chip EEPROM technology, capable of supporting up to 100 read/write cycles, for flexible end-of-line calibration parameter programming. Both devices are ideal for automotive applications requiring angle measurements from 0° to 360°, such as motor position measurements for pumps and other actuators, which demand low latency and high resolution. The A1330 also includes on-chip scaling to support short-stroke applications with as little as 11.25° of movement, such as valve position, pedal position, and fuel tank level detection.
The stacked nature of the dual-pill assembly provides better channel-to-channel matching than more traditional side-by-side assembly techniques. This is a key parameter for safety-critical applications where the output of the two sensors is compared to ensure the system is operating safely. Both single- and dual-pixel versions of the A1330 are offered in a low-profile, lead-free, matte, low-profile (Pb) 8-pin TSSOP package.
