MAX35101 EVALUATION KIT AVAILABLE Time-to-Digital Converter with Analog Front-End General Description 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. Multihit capability with stop-enable windowing allows the device to be fine-tuned for the application.
