MAX154BCNG+

Analog To Digital Converters (ADC) Overview

The MAX154BCNG+ is a CMOS high-speed 8-bit analog-to-digital converter (ADC) manufactured by Analog Devices / Maxim Integrated. It features four single-ended analog input channels and operates from a single +5V supply. The device utilizes a half-flash conversion architecture with a built-in track/hold function, eliminating the need for external components. It includes an internal 2.5V reference and provides latched three-state data outputs for direct microprocessor interfacing. Key electrical specifications include a typical conversion time of 2.0µs, a maximum sampling rate of 400kS/s, and a total unadjusted error of ±1/2 LSB. The component is housed in a 24-pin narrow plastic DIP package and supports an operating temperature range of 0°C to +70°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 4-channel analog multiplexer, track/hold circuit, and 2.5V internal reference into a single chip
• Employs a half-flash conversion technique to achieve high-speed 8-bit resolution without external logic
• Provides latched three-state data outputs compatible with standard microprocessor buses
• Supports flexible digital interface modes allowing operation with or without processor wait states

Analog To Digital Converters (ADC) Applications

• Digital Signal Processing systems
• High-Speed Data Acquisition applications
• Telecommunications equipment
• High-Speed Servo Control loops
• Audio Instrumentation devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'C' confirms the commercial temperature range of 0°C to +70°C and the 'NG' indicates the 24-pin narrow plastic DIP package. Confirm RoHS compliance status through official manufacturer documentation as '+'. Ensure the source impedance of the driving circuit remains below 100Ω to prevent settling errors during the internal acquisition phase.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a compact solution for multi-channel signal digitization is required without external track/hold amplifiers. The MAX154 variant is appropriate for designs needing four inputs, whereas the MAX158 offers eight channels. Consider the half-flash architecture's speed versus noise performance requirements. Verify that the system power supply is strictly regulated at +5V to maintain specified accuracy levels.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX154/MAX158 family of CMOS high-speed ADCs. The MAX154 specifically denotes the four-channel version, while the MAX158 provides eight channels. Both share identical core conversion architectures and timing characteristics. The BC grade specifies the accuracy class and temperature rating within the broader product line.
