MAX154ACWG+

Analog To Digital Converters (ADC) Overview

The MAX154ACWG+ 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 typical conversion time of 2.5µs per channel, achieving a maximum sampling rate of 400kS/s across all channels. The device utilizes a half-flash architecture and includes a built-in track/hold function. Data outputs are provided via latched three-state buffers for direct microprocessor interfacing. It is housed in a 24-pin Wide SO package and supports an industrial operating temperature range of 0°C to +70°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 2.5V on-chip voltage reference and built-in track/hold circuitry to eliminate external components.
• Features four analog input channels with a half-flash conversion architecture for high-speed data acquisition.
• Provides latched three-state data outputs that allow direct connection to microprocessor buses without external logic.

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'WG+' against current manufacturer documentation to confirm the package type and lead-free status. Confirm the 'A' grade accuracy specification matches the design requirements. Check for obsolescence notices as this component family may have limited availability or end-of-life status.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX154ACWG+ when four single-ended input channels are required with high-speed conversion capabilities. Ensure the system can accommodate the 400kS/s aggregate sampling rate. Verify that the 0°C to +70°C industrial temperature range meets environmental constraints. Consider the MAX158 variant if eight channels are needed instead of four.

Analog To Digital Converters (ADC) Part Context

The MAX154ACWG+ belongs to the MAX154/MAX158 series of CMOS high-speed ADCs. This family is characterized by its integration of multiplexers, references, and track/holds into a single chip. The AC grade specifies ±1/2 LSB total unadjusted error, distinguishing it from the BC grade which has ±1 LSB error. The WG+ suffix denotes the 24-pin Wide SOIC package with lead-free construction.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX154BCWG+ offers similar functionality but with a ±1 LSB error specification instead of ±1/2 LSB. For applications requiring eight channels, the MAX158ACWG+ is the direct functional equivalent within the same package and performance class.
