MAX158ACWI+

Analog To Digital Converters (ADC) Overview

The MAX158ACWI+ is an 8-bit CMOS analog-to-digital converter featuring eight single-ended analog input channels and a half-flash architecture. It operates from a single +5V supply with a typical conversion time of 2µs per channel, supporting a maximum sampling rate of 400kS/s across all channels. The device integrates a 2.5V internal reference and a built-in track/hold circuit, eliminating external components. Data outputs utilize latched three-state buffers for direct microprocessor bus interfacing. It functions within a commercial temperature range of 0°C to +70°C and is housed in a 28-pin Wide SO package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix ACWI against the manufacturer's current product status documentation. Confirm that the component meets the required commercial temperature specifications and package dimensions before integration into the design. Ensure compatibility with existing board layouts regarding pin assignments and power requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and high-speed multiplexed input are required. The integrated reference simplifies the design by removing the need for external voltage references. Consider the half-flash architecture for applications demanding fast conversion times without complex timing logic.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX154/MAX158 family of high-speed ADCs. The MAX158 variant specifically provides eight analog inputs compared to the four available in the MAX154. Both share identical core conversion architectures and interface protocols, differing primarily in channel count and pin configuration.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements include other parts within the MAX154/MAX158 series such as the MAX158AEAI+ or MAX158BEWI+, depending on the required temperature grade and accuracy class. Verify pinout compatibility and electrical characteristics before substitution.
