MAX176BEWE+

Analog To Digital Converters (ADC) Overview

The MAX176BEWE+ is a 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It utilizes successive approximation register (SAR) architecture and operates with a single-ended input configuration. The device supports a sampling rate of 250 kS/s and features an internal reference voltage. Power requirements include a 5V digital supply and analog supplies ranging from -12V to -15V. Data transmission occurs via a 3-wire SPI interface. The component is housed in a 16-SOIC surface-mount package and is rated for operation within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 12-bit SAR ADC core with a built-in sample-and-hold circuit for accurate signal capture.
• Provides a serial peripheral interface (SPI) compatible communication protocol for simplified microcontroller connectivity.
• Includes an on-chip internal reference voltage source, reducing external component count.
• Operates with dual power supplies to accommodate wide dynamic input voltage ranges.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring precise analog signal digitization.
• Data acquisition modules for monitoring sensor outputs in automated environments.
• Battery-powered instrumentation where low power consumption and high resolution are critical.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BEWE against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Ensure that the ordering information matches the required operating temperature range and package type. Cross-reference the part number with authorized distributors to confirm current availability status and authenticity before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 250 kS/s throughput are sufficient for the application. Consider the SOIC-16 package constraints for PCB layout. Evaluate the need for the internal reference versus external precision references based on system accuracy requirements. Confirm that the SPI interface timing aligns with the host controller capabilities.
