MAX35104ETL+T

Sensor And Detector Interfaces Overview

The MAX35104ETL+T is a gas flow meter system-on-chip (SoC) manufactured by Analog Devices Inc. under the Maxim Integrated brand. It functions as a time-to-digital converter with an integrated analog front end for thermal mass flow sensors. The device operates on a single supply voltage ranging from 2.3 V to 3.6 V, with a typical operating current of 62 µA. It features two independent channels and communicates via a 4-wire SPI interface. The component is housed in a TQFN-EP-40 package suitable for surface mount installation and supports an industrial temperature range from -40°C to +85°C.

Sensor And Detector Interfaces Feature Summary

• Integrated analog front end designed specifically for thermal mass flow sensor signal conditioning
• Dual-channel architecture enabling simultaneous measurement of two distinct flow paths
• Low-power operation optimized for battery-powered or energy-constrained applications
• Digital output capability through standard serial peripheral interface communication

Sensor And Detector Interfaces Applications

• Industrial process control systems utilizing thermal mass flow meters
• Environmental monitoring devices measuring gas concentrations
• Semiconductor manufacturing tools requiring accurate gas delivery control

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected distributor provides traceability data consistent with Analog Devices quality standards. Check for any recent product change notices that may affect pinout or electrical characteristics.

Sensor And Detector Interfaces Selection Notes

Select this component when dual-channel thermal mass flow measurement is required within a compact form factor. Consider the low power consumption profile for portable or remote sensing applications. Verify that the SPI interface compatibility matches the host microcontroller's digital capabilities. Evaluate the TQFN-EP-40 package constraints against available PCB real estate and thermal management requirements.

Sensor And Detector Interfaces Part Context

The MAX35104 belongs to the MAX3510x family of sensor interface devices developed by Maxim Integrated, now part of Analog Devices. This series focuses on providing complete solutions for thermal mass flow sensing applications. The ETL+ designation identifies the specific lead-free, tape-and-reel variant of the chip. It complements other members like the MAX35102 which lacks certain integrated features found in the MAX35104.

Sensor And Detector Interfaces Replacement Considerations

The MAX35102 serves as a related alternative within the same family but lacks the RTC and flash memory present in the MAX35104. Designers should verify functional equivalence regarding the analog front end and channel count before substitution. Pin compatibility must be confirmed across the specific package variants being compared.
