Maxim Introduces MAXQ7667 SoC (System-on-Chip), Mixed-Signal Microcontroller for Ultrasonic Sensor Applications

The MAXQ7667 SoC provides a cost-effective solution for applications that must measure weak signals over long distances or identify multiple targets. Its integrated functions, moreover, allow designers to add intelligence to cost-sensitive sensor-conditioning applications. The MAXQ7667 is optimized for automotive-sensor systems such as EPA (electronic parking assist) and PDC (park-distance control); it is also well suited for industrial processing, automation, and handheld applications requiring position measurement. This 7mm x 7mm device integrates the main functional blocks required to accurately measure position, including burst control (pulse transmission), analog echo reception, digital signal processing, and a microcontroller. This advanced integration reduces system cost and increases sensor-mounting options. The MAXQ7667 features a programmable burst-frequency generator to compensate for transducer tolerances, adjust frequency with temperature, and perform diagnostics. Programmable burst and duty cycles can optimize power to match environmental conditions…
