5 PGA460 Parameters

Optimization is the most cost efficient and least time consuming when all parameters are controlled by and verified in software. The integration of all key operating parameters of the PGA460 device enables software based performance sweeps and automated module characterization. This section lists the PGA460 registers and parameters from greatest importance to least importance. The ultrasonic module example used for this section assumes the use of a Murata MA58MF14-7N closed-top transducer and EPCOS B78416A2232A003 fixed center-tap transformer at a voltage reference of 12 V DC.
