MAX154AENG+

Analog To Digital Converters (ADC) Overview

The MAX154AENG+ is a CMOS high-speed 8-bit analog-to-digital converter (ADC) featuring four multiplexed analog input channels and an integrated 2.5V reference. It operates from a single +5V supply with a conversion time of 2.5µs per channel. The device utilizes a half-flash architecture, combining two 4-bit flash ADC sections to achieve 8-bit resolution. It includes a built-in track/hold function and three-state data outputs for direct microprocessor interfacing without external logic. The component supports industrial temperature ranges from -40°C to +85°C and is housed in a 24-pin Plastic DIP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 2.5V on-chip reference and built-in track/hold circuitry

• Features three-state buffered digital outputs for direct bus connection

Analog To Digital Converters (ADC) Applications

• Digital Signal Processing
• High-Speed Data Acquisition
• Telecommunications
• High-Speed Servo Control
• Audio Instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'ENG+' corresponds to the 24-pin Plastic DIP package and the -40°C to +85°C industrial temperature range. Confirm that the error specification matches the ±1/2 LSB requirement for this grade. Ensure compatibility with existing board layouts designed for standard 24-DIP footprints before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-supply 8-bit ADC with integrated multiplexing and reference is required. The half-flash architecture provides faster conversion speeds compared to successive approximation types. Verify that the source impedance driving the analog inputs remains below 100Ω to prevent settling errors during the internal acquisition phase.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX154/MAX158 family of CMOS high-speed ADCs. While the MAX154 variant offers four analog input channels, the MAX158 counterpart provides eight channels. Both share identical core specifications regarding resolution, conversion speed, and power supply requirements, differing primarily in channel count and pin assignments.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same package include the MAX154BENG+, which shares the 24-PDIP form factor but carries a ±1 LSB error specification instead of ±1/2 LSB.
