MAX1340BETX+

ADCs/DACs - Special Purpose Overview

The MAX1340BETX+ is a specialized data acquisition integrated circuit featuring a multichannel 12-bit analog-to-digital converter (ADC) and a quad 12-bit digital-to-analog converter (DAC). It integrates an internal temperature sensor, configurable general-purpose I/O ports, and a FIFO buffer. The device operates on a single +4.75V to +5.25V supply and communicates via a 25MHz SPI-compatible serial interface. Key electrical parameters include a 225ksps ADC conversion rate, 2.0µs DAC settling time, and low glitch energy of 4nV·s. It is housed in a TQFN-36 package.

ADCs/DACs - Special Purpose Feature Summary

• Integrated 12-bit ADC with up to 8 input channels and 225ksps throughput
• Quad 12-bit DAC with 2.0µs settling time and low glitch energy
• Internal ±1°C accurate temperature sensor and programmable GPIOs
• Built-in FIFO for reduced processor overhead and AutoShutdown mode

ADCs/DACs - Special Purpose Applications

• Industrial process control systems requiring multi-channel signal conditioning
• Closed-loop digital control applications utilizing fast-response DAC outputs
• Data acquisition modules with integrated environmental monitoring needs

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix ETX against the official datasheet to confirm the TQFN-36 package variant. Confirm RoHS compliance status through manufacturer documentation. Check current availability as distribution status may vary by region. Ensure the ordering part number matches the exact functional revision required for the design.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a combined ADC/DAC solution with integrated sensing is required. The MAX1340B supports both 4-channel and 8-channel ADC configurations within the family; verify channel count requirements. Consider the 2.5mA active current consumption at full speed versus 22µA at lower speeds for power budgeting. Ensure the system voltage aligns with the strict 4.75V to 5.25V operating range.

ADCs/DACs - Special Purpose Part Context

This part belongs to the MAX1340B series, which includes variants like the MAX1342, MAX1346, and MAX1348. These devices share core functionalities such as the 12-bit resolution and serial interface but differ in GPIO availability and ADC channel counts. The MAX1340 specifically denotes the base configuration within this multichannel data acquisition family.

ADCs/DACs - Special Purpose Replacement Considerations

Cross-reference with other members of the MAX1340/MAX1342/MAX1346/MAX1348 family. Verify pin compatibility and functional differences regarding GPIO presence and ADC channel count before substitution.
