MAX118EPI+

Analog To Digital Converters (ADC) Overview

The MAX118EPI+ is an 8-bit, 8-channel analog-to-digital converter (ADC) utilizing a half-flash architecture. It operates from a single +5V supply and achieves a conversion time of 660ns per channel, supporting a sampling rate of 1Msps. The device features an internal track/hold circuit and requires no external clock. A dedicated power-down pin reduces current consumption to typically 1µA. Data outputs utilize latched, three-state buffers for direct connection to an 8-bit parallel microprocessor data bus. The component is housed in a 28-pin wide plastic DIP package.

Analog To Digital Converters (ADC) Feature Summary

• Microprocessor-compatible interface with latched three-state output buffers
• Internal track/hold circuitry for fast signal digitization
• Power-down mode significantly reduces supply current consumption
• Half-flash technique enables high-speed conversion without external clocks

Analog To Digital Converters (ADC) Applications

• High-speed digital signal processing systems
• Remote data acquisition networks
• Portable equipment requiring low-power operation
• Communications systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'EPI+' against official documentation to confirm the 28-pin wide plastic DIP package and industrial temperature range (-40°C to +85°C). Ensure compatibility with existing board layouts designed for this form factor. Cross-reference the manufacturer's latest datasheet for any potential updates to electrical characteristics or recommended operating conditions prior to final procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX118EPI+ when eight single-ended analog input channels are required alongside high-speed conversion capabilities. This component is suitable for designs needing direct interfacing with 8-bit parallel buses without additional logic. Consider the power-down feature for applications requiring significant current reduction during idle periods. Verify that the system voltage aligns with the specified +5V single-supply requirement.

Analog To Digital Converters (ADC) Part Context

The MAX118EPI+ belongs to the MAX114/MAX118 family of microprocessor-compatible ADCs. While the MAX114 variant provides four channels in a 24-pin package, the MAX118 expands this to eight channels within a 28-pin footprint. Both devices share identical core performance metrics, including the half-flash architecture and 1Msps sampling rate, differing primarily in channel count and physical dimensions.
