The AK7451 angular and linear position sensor is a highly precise, low-power monolithic CMOS integrated circuit with a dual-channel, analog-to-digital converter. The device operates from a single 2.7-5.5V power supply and provides an output of either an analog voltage or a digital value that represents the angular or linear position of a moving object. This type of sensor is commonly used in the automobile, aerospace, medical, and consumer electronics industries to measure and provide feedback on linear and angular positions.

The AK7451 is designed to accurately measure the angular or linear position of a moving object down to a resolution of 0.01° or 0.025mm, depending on the configuration. It features a configurable precision that can be set to up to 12 bits. The sensor operates on a single-ended power supply, and it is also manually programmable for either voltage or serial output. The onboard EEPROM enables the user to customize the sensor to the application. Furthermore, the device also includes an Overvoltage Protection (OVP) with adjustable trip levels.

The AK7451 angle or linear position sensor works in two different modes, Single Conversion and Continuous Conversion. In Single Conversion, the analog-to-digital converter samples the input for one conversion cycle and then outputs the conversion result. In Continuous Conversion, the analog-to-digital converter samples the input continuously and creates an output for each conversion cycle.

The AK7451 has a range of applications including automotive, industrial, medical, and consumer electronics. Automotive applications include airbag deploy system monitoring, vehicle speed sensor measurements, and fuel tank level monitoring. Industrial applications include linear and angular position sensors used in robotics and automated systems. Medical applications include measurement of oxygen or blood glucose levels. Consumer electronics applications include gaming devices, digital cameras, and digital audio players.

The AK7451 is a reliable, low-power, and highly accurate angular and linear position sensor that is capable of providing precise measurements down to a resolution of 0.01° or 0.025mm. It is suited for a wide variety of applications in the automotive, aerospace, medical, and consumer electronics industries where precise measurements of angular and linear positions are required.
