MAX1231BCTI+T

Analog To Digital Converters (ADC) Overview

The MAX1231BCTI+T is a 12-bit successive-approximation analog-to-digital converter (ADC) featuring an internal temperature sensor, internal reference, 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. It includes a 10MHz SPI/QSPI/MICROWIRE-compatible serial interface, ±1 LSB INL/DNL accuracy, and AutoShutdown functionality for low-power applications.

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 the operating range
• Configurable analog multiplexer supporting true differential and single-ended inputs
• Internal 2.5V voltage reference or provision for external differential reference

Analog To Digital Converters (ADC) Applications

• Data-acquisition systems
• Industrial control systems
• Patient monitoring equipment
• Data logging instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BCTI' against official documentation to confirm package type and temperature grade. Confirm RoHS compliance status as indicated by the '+' designation. Ensure compatibility with existing system power rails and serial interface protocols before integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 16-channel acquisition is required within a compact footprint. Compare against MAX1229 (12 channels) or MAX1227 (8 channels) if fewer inputs suffice. Verify that the 12-bit resolution and 300ksps speed meet system bandwidth requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1227/MAX1229/MAX1231 family of 12-bit ADCs. While sharing core architecture, the MAX1231 specifically provides 16 input channels compared to the 12-channel MAX1229 and 8-channel MAX1227. All variants share similar pinouts and feature sets like the internal FIFO and temperature sensor.

Analog To Digital Converters (ADC) Replacement Considerations

MAX1229BCTI+T offers 12 channels; MAX1227BCTI+T offers 8 channels. These are functionally compatible but provide fewer input channels. Verify channel count sufficiency before substituting.
