MAX154BENG

Analog To Digital Converters (ADC) Overview

The MAX154BENG is a CMOS high-speed 8-bit analog-to-digital converter (ADC) featuring four analog input channels. It operates from a single +5V supply and includes an internal 2.5V reference, eliminating the need for external components. The device utilizes a half-flash architecture with a built-in track/hold function, achieving a conversion time of 2.5µs per channel. It supports parallel data output via latched three-state buffers and accepts multiplexer address inputs A0, A1, and A2. The component is housed in a 24-pin narrow plastic DIP package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates four analog input channels with a built-in multiplexer and track/hold circuitry
• Includes an on-chip 2.5V voltage reference for simplified system design
• Features a half-flash conversion architecture for high-speed operation without external clocks
• Provides direct microprocessor interface capability through memory-mapped or I/O port addressing

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 ordering suffix 'E' confirms the industrial temperature range of -40°C to +85°C and the 'NG' designation indicates the 24-pin narrow plastic DIP package. Confirm RoHS compliance status as historical documentation may vary. Ensure the source document explicitly lists the MAX154BENG variant to validate the ±1 LSB error specification associated with this accuracy grade.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX154BENG when four single-ended analog channels are required with an 8-bit resolution and a sampling rate up to 400kS/s. This part is suitable for designs needing a compact 24-pin DIP footprint while maintaining a wide operating temperature range. Consider the internal reference and track/hold features if minimizing external component count is a priority.

Analog To Digital Converters (ADC) Part Context

The MAX154BENG belongs to the MAX154/MAX158 family of CMOS high-speed ADCs. While the MAX154 provides four channels, the MAX158 variant offers eight channels. Both share identical core specifications regarding conversion speed, resolution, and interface logic. The B-grade designation specifically denotes a total unadjusted error of ±1 LSB, distinguishing it from the higher-precision A-grade variants.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX154AENG serves as a higher-accuracy alternative within the same package offering ±1/2 LSB error. For expanded channel counts, the MAX158 series provides eight inputs. Verify that any substitute maintains the 24-pin DIP form factor and compatible logic levels.
