MAX1346BETX+T

ADCs/DACs - Special Purpose Overview

The MAX1346BETX+T is a specialized data acquisition integrated circuit featuring a quad 12-bit analog-to-digital converter (ADC) and four 12-bit digital-to-analog converters (DACs). It incorporates a serial peripheral interface (SPI)-compatible communication port, an internal temperature sensor, and general-purpose I/O ports. The device operates within a supply voltage range of +4.75V to +5.25V. Key electrical parameters include a 225ksps ADC conversion rate, DAC settling time of 2.0µs, and current consumption of 2.5mA at full throughput. It is housed in a QFN-EP-36 package.

ADCs/DACs - Special Purpose Feature Summary

• Integrated quad 12-bit SAR ADC with 225ksps throughput
• Quad 12-bit DACs with 2.0µs settling time and low glitch energy
• Internal ±1°C accurate temperature sensor
• Configurable GPIO ports and FIFO buffer for data handling

ADCs/DACs - Special Purpose Applications

• Digital control of fast-response closed-loop systems
• Industrial process control instrumentation
• Data acquisition systems requiring simultaneous analog input and output

ADCs/DACs - Special Purpose Procurement Notes

Verify the suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status via official manufacturer documentation. Ensure the specific lot date code meets project requirements. Check for obsolescence notices or lifecycle changes on the Analog Devices website before finalizing procurement plans.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring integrated multichannel signal conditioning with minimal external reference components. The internal 4.096V reference simplifies design compared to external reference solutions. Consider the QFN-EP-36 thermal pad requirements for adequate heat dissipation during continuous operation at high sampling rates.

ADCs/DACs - Special Purpose Part Context

This part belongs to the MAX1346B family, which includes variants like the MAX1340B and MAX1342B. These devices share core functionalities such as 12-bit resolution and SPI compatibility but differ in channel counts and GPIO configurations. The MAX1346B specifically integrates four ADC channels and four DAC channels.

ADCs/DACs - Special Purpose Replacement Considerations

The MAX1340BETX+ and MAX1342BETX+ are pin-compatible members of the same family. Verify channel count requirements, as the MAX1340 offers different ADC/DAC configurations. No direct cross-manufacturer substitutes are documented in public sources.
