MAX111BCWE+T

Analog To Digital Converters (ADC) Overview

The MAX111BCWE+T is a low-cost, 2-channel, ±14-bit serial analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It utilizes an internal auto-calibration technique to achieve high resolution without external components. The device operates on a single +5V supply and supports differential or single-ended input signals. Key electrical parameters include a typical supply current of 640µA, which reduces to 4µA in shutdown mode. It features a serial interface compatible with SPI, QSPI, and MICROWIRE standards, allowing for up to 50 conversions per second. The component is housed in a 16-pin Wide SO package and operates within a temperature range of 0°C to +70°C.
