MAX111BCWE+

Analog To Digital Converters (ADC) Overview

The MAX111BCWE+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 a sigma-delta architecture with internal auto-calibration for offset and gain-error correction. The device supports differential inputs in the ±1.5V range or single-ended inputs from 0V to +1.5V. Key electrical parameters include a resolution of 14 bits plus sign and overrange, a maximum sampling rate of 50 conversions per second, and a typical supply current of 640µA, which reduces to 4µA in shutdown mode. It utilizes an SPI/QSPI/MICROWIRE compatible serial interface and is housed in a 16-pin Wide SO package.

Analog To Digital Converters (ADC) Feature Summary

• Internal auto-calibration technique eliminates the need for external components for offset and gain-error correction.
• Sigma-delta architecture provides high linearity with 50Hz/60Hz rejection capabilities.
• Flexible serial interface compatible with standard SPI, QSPI, and MICROWIRE protocols.
• Low power consumption with dedicated power-down modes reducing current to 4µA.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the 'C' temperature grade corresponds to the 0°C to +70°C operating range required by your design. Ensure the manufacturer is identified as Analog Devices Inc./Maxim Integrated to guarantee component authenticity and datasheet alignment.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring a single +5V supply and differential or single-ended input ranges up to ±1.5V or 0-1.5V respectively. Choose the MAX111 variant over the MAX110 if bipolar supplies are unavailable. Consider the 16-pin Wide SO package for surface-mount assembly constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX110/MAX111 family of low-cost, high-resolution serial ADCs. It shares architectural similarities with the MAX110 but is optimized for single-supply operation. The family utilizes first-order sigma-delta conversion loops and is designed for battery-powered or remote-sensing applications where low power and high resolution are critical.
