Mikroelektronika MIKROE-3302: PGA460 Integrated Ultrasonic Signal Processor, Transducer Driver, SPI,

Technical description of the product (MIKROE-3302):

MIKROE-3302 PGA460. Integrated ultrasonic signal processor and transducer driver, SPI, 3.3V. The Ultrasonic 2 Click board is an ultrasonic range detection Click board, capable of detecting both near-field and far-field objects. It is equipped with the PGA460, a highly-integrated system-on-chip (SoC), based on SONAR principle. This SoC consists of a low-noise analog front end (AFE) with a programmable time-varying gain stage, a digital signal processor (DSP), and an integrated transducer driver. The PGA460 offers very accurate and reliable range detection, regardless of the position of an object: the incoming echo signal is conditioned and dynamically amplified over time before it is digitized, so that the optimal signal-to-noise ratio can be achieved. Applications: It can be used for park assist, collision detection, lane departure warning (LDW), and similar automotive-related applications, object distance and position sensing, presence and proximity detection, drone landing assist and obstacle detection applications, etc. On-board modules: PGA460, an integrated ultrasonic signal processor and transducer driver by Texas Instruments. TLV61046, a 28V output voltage boost converter by Texas Instruments. Key Features: A highly integrated SoC with advanced DSP processing functions which allow very accurate and reliable object range detection, processed distance data available on the output, a complete ultrasonic range detection solution supported by software libraries for rapid development, non-volatile parameter storage for a fast initialization. Interface: SPI. Input Voltage: 3.3V. Click board size: M (42.9 x 25.4 mm).
