Analog Front End IC with 8bit MCU and UART / I2C / I/O communication
The GW7125 is a device that combines an integrated microcontroller and an analog front end to provide ultrasonic range detection from 0 to 10 cm to using a minimal number of components. Its pulse-width modulation (PWM) output allows for programmable bursts ranging from 30kHz to 80kHz to be sent to a single ultrasonic transducer connected through a center-tapped transformer. With the use of supported transducers, this device enables distance measurement between 20cm and 7m, achieving a resolution of 1mm. Fast Calibration Data and Program Update via LIN interface
