MAX1231BETI+T

Analog To Digital Converters (ADC) Overview

The MAX1231BETI+T is a 12-bit, 300ksps analog-to-digital converter (ADC) featuring an internal temperature sensor and FIFO. It operates from a single +2.7V to +3.6V supply with 1mA current consumption at maximum sampling rate. The device includes an internal 2.5V reference or supports external differential references. It offers 16 configurable input channels supporting single-ended or true differential inputs in unipolar or bipolar modes. Accuracy specifications include ±1 LSB INL and DNL without missing codes over the operating temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing this component. Confirm that the B-grade designation aligns with required performance tolerances for your design. Ensure the TQFN-EP package footprint matches your PCB layout constraints. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX1231BETI+T when 16 input channels are required for high-density data acquisition. Choose this part for applications needing integrated temperature sensing alongside voltage conversion. Consider the low power consumption for battery-operated systems requiring continuous monitoring. Verify interface compatibility with the host microcontroller's serial peripheral capabilities.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX1227/MAX1229/MAX1231 family of 12-bit ADCs. The MAX1231 variant specifically provides 16 input channels, whereas the MAX1229 offers 12 and the MAX1227 provides 8. All members share similar architectural features including the SAR conversion technique and internal FIFO structure.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX1229 and MAX1227 are functionally compatible alternatives within the same series but offer fewer input channels. Verify channel count requirements before substituting. Other Maxim Integrated ADCs may require significant schematic and software modifications due to differing register maps.
