MAX1346BETX+

ADCs/DACs - Special Purpose Overview

The MAX1346BETX+ is a specialized data acquisition integrated circuit featuring a quad, 12-bit digital-to-analog converter (DAC) and a four-channel, 12-bit analog-to-digital converter (ADC). It integrates a temperature sensor and configurable general-purpose I/O ports. The device operates on a single +4.75V to +5.25V supply, consuming 2.5mA at 225ksps throughput. It includes an internal 4.096V reference, a FIFO buffer, and supports SPI/QSPI/MICROWIRE interfaces in a QFN-EP-36 package.

ADCs/DACs - Special Purpose Feature Summary

• Integrated quad 12-bit DAC with 2.0µs settling time and low glitch energy (4nV·s)
• Four-channel 12-bit ADC with 225ksps conversion rate
• Internal ±1°C accurate temperature sensor and programmable GPIO ports
• Built-in FIFO for reduced processor overhead and AutoShutdown mode

ADCs/DACs - Special Purpose Applications

• Digital control of fast-response closed-loop systems
• Multichannel data acquisition systems requiring simultaneous ADC/DAC functionality
• Industrial process control applications needing integrated sensing and actuation

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix ETX against official Analog Devices documentation to confirm the QFN-EP-36 package and industrial temperature range (-40°C to +85°C). Ensure compatibility with the required serial interface protocol (SPI/QSPI/MICROWIRE) before procurement.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a single IC solution is required for both analog input and output channels. The MAX1346B variant specifically provides four ADC inputs, distinguishing it from the eight-input MAX1348. Verify that the system power supply remains within the strict +4.75V to +5.25V operating window.

ADCs/DACs - Special Purpose Part Context

This part belongs to the MAX1340B family of multichannel ADCs/DACs. The MAX1346BETX+ is functionally similar to the MAX1340B but differs in ADC channel count. All variants share the same core architecture, including the internal reference, FIFO, and GPIO capabilities.

ADCs/DACs - Special Purpose Replacement Considerations

The MAX1340BETX+ serves as a functional substitute if only two ADC channels are required. The MAX1342BETX+ and MAX1348BETX+ offer different ADC channel configurations (two and eight channels, respectively) while maintaining identical DAC and peripheral features.
