MAX1358BETL+W

ADCs/DACs - Special Purpose Overview

The MAX1358BETL+W is a smart data-acquisition system integrating a 16-bit sigma-delta ADC, dual 10-bit force-sense DACs, an uncommitted op amp, and analog switches. It operates on a single +1.8V to +3.6V supply, consuming 1.15mA in normal mode and 3µA in sleep mode. The device features dual 10:1 differential input multiplexers with a programmable-gain amplifier (PGA) offering gains of 1, 2, 4, or 8. System support includes selectable internal voltage references (1.25V, 2.048V, 2.5V), temperature sensors, a real-time clock with alarm, user-programmable I/Os, and interrupt generation. Communication is handled via SPI/QSPI/MICROWIRE serial interfaces.

• Industrial control systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the ordering suffix 'W' against official manufacturer documentation to confirm specific packaging or environmental compliance details not explicitly defined in standard datasheets. Confirm availability status through authorized distributors as stock levels fluctuate. Ensure the component meets RoHS requirements if indicated by the '+' suffix in related part numbers.

ADCs/DACs - Special Purpose Selection Notes

Select this model for applications requiring high-resolution signal acquisition with integrated conditioning. The extended temperature range (-40°C to +85°C) suits industrial environments. Verify that the required conversion rate (10sps to 477sps) and PGA gain settings align with the target sensor's output characteristics and noise floor requirements.

ADCs/DACs - Special Purpose Part Context

This component belongs to the MAX1358B family of smart data-acquisition systems from Analog Devices/Maxim Integrated. It consolidates multiple analog front-end functions into a single chip, reducing external component count. The ETL+ designation typically indicates the extended temperature range and lead-free/RoHS-compliant packaging within the TQFN-EP form factor.
