MAX35103

Reduced Power Time-to-Digital Converter

with AFE, RTC, and Flash

General Description

Beneﬁts and Features

● High Accuracy Flow Measurement for Billing and

The MAX35103 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 con-

sumes about half the average power and increases the

maximum ToF measurement frequency in event timing

mode from 2Hz to 16Hz.

Leak Detection

• Time-to-Digital Accuracy Down to 20ps

• Measurement Range Up to 8ms

• Two 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

With a time measurement accuracy of 20ps and auto-

matic differential time-of-flight (ToF) measurement, this

device makes for simplified computation of liquid flow.

● Maximizes Battery Life with Low Device and Overall

System Power

Average power consumption is the lowest available with

ultra-low 5.5μA ToF measurement and < 125nA duty-

cycled temperature measurement.

• Ultra-Low 5µA ToF Measurement and < 125nA

Duty-Cycled Temperature Measurement

•

Event Timing Mode Reduces Host Microcontroller

Overhead to Minimize System Power Consumption

Applications

● Ultrasonic Heat Meters

● Ultrasonic Water Meters

● Ultrasonic Gas Meters

• 2.3V to 3.6V Single-Supply Operation

● High-Integration Solution Minimizes Parts Count and

Reduces BOM Cost

• 8KB of Nonvolatile Flash Memory for Data Logging

• Built-in Real Time Clock

• Small, 5mm x 5mm, 32-Pin TQFP Package

• -40°C to +85°C Operation
