MAX1231BCTI+

Analog To Digital Converters (ADC) Overview

The MAX1231BCTI+ is a 12-bit successive-approximation analog-to-digital converter (ADC) featuring an internal temperature sensor and a 16-entry FIFO buffer. It supports up to 16 single-ended or 8 differential input channels with configurable unipolar/bipolar modes. The device operates on a +2.7V to +3.6V supply, achieving sampling rates up to 300ksps via an external clock or internally timed modes. Key specifications include ±1 LSB INL/DNL accuracy, a 10MHz SPI-compatible serial interface, and operation within the -40°C to +85°C extended temperature range.

Analog To Digital Converters (ADC) Feature Summary

• Integrated 16-entry first-in/first-out (FIFO) buffer for efficient data handling
• On-chip temperature sensor with specified accuracy over temperature range
• Configurable analog multiplexer supporting true differential and single-ended inputs
• Internal 2.5V reference option alongside support for external differential references

Analog To Digital Converters (ADC) Applications

• System supervision
• Data-acquisition systems
• Industrial control systems
• Patient monitoring
• Data logging

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BCTI+' against official documentation to confirm package type and temperature grade. Confirm availability status as distribution listings may vary. Ensure compatibility with existing system voltage levels and serial interface requirements before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 16-channel acquisition is required with integrated buffering. Compare against MAX1229 (12 channels) or MAX1227 (8 channels) if fewer inputs suffice. Verify that the 12-bit resolution and 300ksps speed meet application bandwidth needs.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1227/MAX1229/MAX1231 family of low-power, serial-output ADCs. It shares architectural features such as the SAR conversion technique, internal track-and-hold, and compatible serial interfaces with its siblings, differing primarily in channel count and package options.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include MAX1229 and MAX1227 variants, though channel counts differ. Verify pinout compatibility and register mapping if substituting with other Maxim Integrated ADC families.
