MAXQ7667 Overview
Key Specifications
Package: LQFP
Pins: 48
Operating Voltage: 5 V
Max Voltage (typical range): 5.5 V
Description
The MAXQ7667 smart system-on-a-chip (SoC) provides a time-of-flight ultrasonic distance-measuring solution. The device is optimized for applications involving large distance measurement with weak input signals or multiple target identification.
Key Features
- An integrated burst signal generator and echo reception components process ultrasonic signals between 25kHz and 100kHz
- DSP limits noise with a bandpass filter, and creates an echo envelope through demodulation and lowpass filtering
- Input referred noise is a low 0.7µV RMS
- An embedded 16-bit MAXQ20 microcontroller (µC) controls all the preceding functions
- The µC optimizes the burst frequency and reception frequency for each transmission at any temperature
