[原创] Maxim MAX35101超声波热量(流量)表解决方案

Maxim公司的MAX35101是内置了放大器和比较器的时间/数字转换器,是超声波热量(流量)表完整的模拟前(AFE)解决方案.时间/数字转换精度20ps,测量范围高达8ms,单电源2.3V-3.6V工作,主要用在超声波热量表,超声波水表和超声波气表.本文介绍了MAX35101主要特性和优势,框图,应用电路,以及MAXREFDES70#超声波流量表主要特性,框图,电路图,材料清单和PCB元件布局图.

The MAX35101 is a time-to-digital converter with built-in amplifier and comparator targeted as a complete analog front-end (AFE) solution for the ultrasonic heat meter and flow meter markets.

With a time measurement accuracy of 20ps and auto­matic differential time-of-flight (TOF) measurement, this device makes for simplified computation of liquid flow. Early edge detection ensures measurements are made with consistent wave patterns to greatly improve accuracy and eliminate erroneous measurements.
