The MAX35102 is a time-to-digital converter with built-in amplifier and comparator targeted as a low-cost, analog front-end solution for the ultrasonic heat meter and flow meter markets. It is similar to the MAX35101, but with a reduced feature set and without a real-time clock (RTC). The package size has been reduced to 4mm x 4mm x 0.75mm with 0.4mm pin pitch. With a time measurement accuracy of 20ps and automatic differential time-of-flight (ToF) measurement, this device makes for simplified computation of liquid flow. Power consumption is the lowest available with ultra-low 5.5µA ToF measurement and < 125nA duty-cycled temperature measurement. Applications * Ultrasonic Gas Meters * Ultrasonic Heat Meters * Ultrasonic Water Meters * High-Accuracy Flow Measurement for Billing and Leak Detection * Time-to-Digital Accuracy Down to 20ps * Measurement Range Up to 8ms * 2 Channels—Single-Stop Channel * High-Accuracy Temperature Measurement for Precise Heat and Flow Calculations * Up to Four 2-Wire Sensors * PT1000 and PT500 RTD Support * 40mK Accuracy * Maximizes Battery Life with Low Device and Overall System Power * Ultra-Low 5.5µA ToF measurement and < 125nA Duty-Cycled Temperature Measurement * 2.3V to 3.6V Single-Supply Operation * High-Integration Solution Minimizes Parts Count and Reduces BOM Cost * Small, 4mm x 4mm, 32-Pin TQFN Package * -40°C to +85°C Operation https://elecena.pl/product/22324062/time-to-digital-converter-without-rtc 2022-12-27 https://elecena.pl/product/22324062/time-to-digital-converter-without-rtc 2024-03-25
