PGA460-Q1 Overview
The PGA460-Q1 device is a highly-integrated system on-chip ultrasonic transducer driver and signal conditioner with an advanced DSP core. The device has a plimentary low-side driver pair that can drive a transducer either in a transformer based topology using a step-up transformer or in a directdrive topology using external high-side FETs. The device can receive and condition the reflected echo signal for reliable...
