Ultrasonic signal processor and transducer driver 'PGA460'
The PGA460 device is a highly integrated system-on-chip ultrasonic transducer driver and signal conditioner, featuring an advanced DSP core. This device includes a complementary low-side driver pair, allowing it to drive transducers using either a boost transformer-based topology or a direct drive topology with external high-side FETs. The device can receive and condition reflected echo signals, enabling reliable object detection. This functionality is achieved using an analog front end (AFE), which consists of a low-noise amplifier and a subsequent programmable time-varying gain stage that supplies signals to the ADC. **Features** - Fully integrated solution for ultrasonic sensing - Low-noise receiver with programmable 6-point time-varying gain - Built-in DSP for echo envelope detection (BPF, demodulation) - Object detection with 12-point time-varying threshold and two presets *For more details, please contact us.*
