MAX35101

Time-to-Digital Converter with Analog Front-End

General Description

Beneﬁts and Features

● High Accuracy Flow Measurement for Billing

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.

and Leak Detection

• Time-to-Digital Accuracy Down to 20ps

• Measurement Range Up to 8ms

• Two Channels: Single-Stop Channel

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.

Early edge detection ensures measurements are made

with consistent wave patterns to greatly improve accuracy

and eliminate erroneous measurements.

● High Accuracy Temperature Measurement for

Precise Heat and Flow Calculations

• Up to Four (4) 2-Wire Sensors

• PT1000 and PT500 RTD Support

● Maximizes Battery Life with Low Device and

Overall System Power

Multihit capability with stop-enable windowing allows

the device to be fine-tuned for the application. Internal

analog switches, an autozero amplifier/comparator, real-

time clock (RTC), and programmable receiver sensitivity

provide the analog interface and control for a minimal

electrical bill of material solution. The RTC provides an

event timing mode that is configurable and runs cyclic

algorithms to minimize microprocessor interactivity and

increase battery life.

• Low 10μA ToF measurement and < 125nA

Duty-Cycled Temperature Measurement

• Event Timing Mode Reduces Host μC

● Overhead to Minimize System Power Consumption

• 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

Built-in arithmetic logic unit provides TOF difference mea-

surements. A programmable receiver hit accumulator can

be utilized to minimize the host microprocessor access

and thus minimize current consumption.

Applications

● Ultrasonic Heat Meters

● Ultrasonic Water Meters

● Ultrasonic Gas Meters

For temperature measurement, the MAX35101 supports

up to four (4) 2-wire PT1000/500 platinum resistive tem-

perature detectors (RTD).

A simple 4-wire SPI interface allows any microcon-

troller to effectively configure the device for its intended

measurement.

On-board 8KB user flash allows the MAX35101 to be

nonvolatile-configurable and provide nonvolatile energy

use data to be logged. Configuration can be recalled any-

time with a SPI command.
