MAX1230BETI+

Analog To Digital Converters (ADC) Overview

The MAX1230BETI+ is a 12-bit, 300ksps analog-to-digital converter (ADC) featuring an internal reference and temperature sensor. It provides 16 configurable single-ended or differential input channels with ±1 LSB INL/DNL accuracy. The device includes a 16-entry FIFO, scan mode, internal averaging, and AutoShutdown™. Operating from a +5V supply, it draws 2.3mA at maximum sampling rates. Key specifications include a 4.096V internal reference, 10MHz SPI-compatible serial interface, and operation over the -40°C to +85°C extended temperature range in a 28-pin TQFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BETI+' against official documentation to confirm the package type and temperature grade. Ensure the ordering information matches the required thermal performance and pin configuration for your design. Cross-reference the manufacturer's latest datasheet revision to confirm availability and any potential obsolescence notices before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 16-channel acquisition is required alongside integrated temperature sensing. The internal FIFO reduces microprocessor bus overhead during scanning operations. Verify that the system power supply remains stable within the 4.75V to 5.25V range to maintain specified accuracy levels. Consider the external reference option if higher precision than the internal 4.096V reference is necessary for the application.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1226/MAX1228/MAX1230 family of 12-bit ADCs. While sharing core architecture, the MAX1230 specifically offers 16 analog input channels compared to the 8-channel MAX1226 and 12-channel MAX1228. All variants support similar features like FIFO, internal reference, and temperature sensing, but channel count and package options vary by model number.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the MAX1226 and MAX1228, though they offer fewer input channels. Verify pin compatibility and register mapping if substituting between these models. No other cross-family replacements are confirmed in the provided documentation.
