MAX174CCWI+

Analog To Digital Converters (ADC) Overview

The MAX174CCWI+ is a complete 12-bit analog-to-digital converter (ADC) utilizing successive approximation register (SAR) architecture. It integrates an internal buried zener voltage reference and on-chip clock, requiring only decoupling capacitors for operation. The device features a parallel three-state data interface compatible with 8-, 12-, and 16-bit microprocessor buses. It supports versatile analog input ranges including 0 to +10V, 0 to +20V, ±5V, and ±10V via pin strapping. Operating at a maximum conversion time of 8μs, it dissipates 150mW. The component operates within a commercial temperature range of 0°C to +70°C and is housed in a 28-pin Wide SOIC package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'C' corresponds to the commercial temperature grade (0°C to +70°C) and 'WI' indicates the Wide SOIC package. Confirm RoHS compliance status as indicated by the '+' suffix. Ensure the source document explicitly lists this exact part number variant to avoid confusion with other speed grades or package options within the MAX174 family.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 12-bit resolution with 8μs conversion speed is required for single-channel applications. It is suitable for designs needing integrated reference and clock functions to minimize external components. Verify that the parallel interface logic levels match the target microprocessor bus. Consider the ±15V or ±12V supply requirements and ensure adequate thermal management for the specified power dissipation.
