投稿日: 2015-05-24, Maxim Integrated
Maxim's MAX35102 time-to-digital converter is suitable for gas, water, and thermosonic metering applications. The device includes a built-in amplifier and comparator designed to provide a low-cost analog front-end (AFE) solution for the ultrasonic flowmeter market. This device is similar to the MAX35101 but has a reduced feature set and does not include a real-time clock (RTC). The device has 20ps time measurement accuracy and automatic differential time-of-flight (ToF) measurement function, which can simplify the calculation of liquid flow. The company states that power consumption is lowest when using an ultra-low 5.5μAToF measurement and a duty cycle temperature measurement of less than 125nA.
