MAX114ENG+

Analog To Digital Converters (ADC) Overview

The MAX114ENG+ is an 8-bit, 4-channel analog-to-digital converter (ADC) from the MAX114/MAX118 family. It operates on a single +5V supply and utilizes a half-flash architecture to achieve a conversion time of 660ns, supporting a sampling rate of 1Msps. The device features a power-down pin that reduces current consumption to typically 1µA. It includes an internal track/hold circuit and provides latched, three-state data outputs for direct connection to an 8-bit parallel microprocessor bus. The component is housed in a 24-pin Narrow Plastic DIP package and supports an operating temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Microprocessor-compatible interface with latched, three-state buffers for direct bus connection
• Half-flash conversion technique enabling high-speed digitization without external clocking
• Integrated power-down mode significantly reducing standby current consumption
• Internal track/hold circuitry designed to capture fast-changing analog signals

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'ENG+' against the manufacturer's official documentation to confirm the package type and temperature grade. Ensure compatibility with system voltage levels and interface requirements before procurement. Cross-reference the part number with authorized distributors to confirm availability and authenticity.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and 1Msps sampling rate are required for multi-channel applications. The half-flash architecture offers speed advantages over SAR ADCs while maintaining lower complexity than full flash designs. Consider the power-down feature for battery-operated systems where energy efficiency during idle periods is critical.

Analog To Digital Converters (ADC) Part Context

The MAX114ENG+ belongs to the MAX114/MAX118 series of high-speed, 8-bit ADCs. This family is characterized by its microprocessor-friendly interface and ability to operate directly from a +5V supply. The MAX114 variant specifically provides four analog input channels, distinguishing it from the eight-channel MAX118 model within the same functional family.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements include other parts from the MAX114/MAX118 family, such as the MAX114CNG+ or MAX114EAG+, provided they match the required temperature range and package specifications. Verify pinout compatibility and electrical characteristics before substituting.
