MAX111BCAP+T

Analog To Digital Converters (ADC) Overview

The MAX111BCAP+T is a low-cost, 2-channel, ±14-bit serial analog-to-digital converter (ADC) from Analog Devices/Maxim Integrated. It operates on a single +5V supply and features internal auto-calibration for offset and gain-error correction without external components. The device supports differential inputs in the ±1.5V range or single-ended inputs from 0V to +1.5V. It utilizes a sigma-delta architecture with up to 50 conversions per second and offers SPI, QSPI, and MICROWIRE compatibility. Power consumption is 640µA during operation and reduces to 4µA in shutdown mode. It is housed in a 20-pin SSOP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component matches the specific suffix requirements for temperature range and packaging. Confirm that the ordering information aligns with the manufacturer's current documentation to ensure authenticity and correct specifications before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a single +5V supply is required for 14-bit resolution applications. Ensure the input signal range fits within the specified differential or single-ended limits. Verify that the serial interface timing meets the system's clock requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX110/MAX111 family of low-cost, 2-channel serial ADCs. While the MAX110 requires dual supplies, the MAX111 variant is designed for single-supply operation. The BC grade indicates a specific accuracy class within the commercial temperature range.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as other MAX111 variants with different accuracy grades or packages. Verify electrical characteristics match if substituting with similar devices from other manufacturers.
