MAX1031BEEG+T

Analog To Digital Converters (ADC) Overview

The MAX1031BEEG+T is a serial 10-bit analog-to-digital converter (ADC) featuring an internal reference and temperature sensor. It operates from a +2.7V to +3.6V supply with a maximum sampling rate of 300ksps using an external clock. The device includes a 16-entry FIFO, scan mode, internal averaging, and AutoShutdown. It offers 16 configurable input channels supporting single-ended or differential inputs in unipolar or bipolar modes. The part utilizes a 10MHz SPI/QSPI/MICROWIRE-compatible serial interface and is specified over the -40°C to +85°C extended temperature range.

Analog To Digital Converters (ADC) Procurement Notes

Verify the B suffix indicates the extended industrial temperature range (-40°C to +85°C). Confirm the E package corresponds to the 24-pin QSOP form factor. Ensure the T suffix denotes tape and reel packaging for automated assembly processes. Cross-reference the specific ordering code against manufacturer documentation to validate lead times and availability status before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high channel count is required within a compact footprint. The integrated FIFO reduces microprocessor overhead during multi-channel scanning operations. Verify that the 10-bit resolution meets system accuracy requirements. Ensure the 300ksps sampling rate aligns with the bandwidth needs of the monitored signals. Check compatibility with existing SPI or MICROWIRE controller interfaces.

Analog To Digital Converters (ADC) Part Context

This device belongs to the MAX1027/MAX1029/MAX1031 family of low-power serial ADCs. While sharing core architecture, the MAX1031 distinguishes itself by offering sixteen analog input channels compared to eight in the MAX1027 and twelve in the MAX1029. All variants share identical electrical characteristics regarding resolution, speed, and power consumption.

Analog To Digital Converters (ADC) FAQ

How does the FIFO buffer manage overflow conditions?

If the 16-entry FIFO is filled and further conversions are requested without reading data, the oldest ADC results are overwritten by new results.

What is the resolution of the internal temperature sensor?

The internal temperature sensor provides measurements with a resolution of 1/8 degree Celsius.

Can the device operate with both single-ended and differential inputs simultaneously?

No, input channels must be configured via the setup register as either single-ended or differential; they cannot operate in mixed modes concurrently.
