MAX154ACWG+T

Analog To Digital Converters (ADC) Overview

The MAX154ACWG+T is a CMOS high-speed 8-bit analog-to-digital converter (ADC) featuring four single-ended analog input channels. It utilizes a half-flash architecture with a built-in track/hold and an internal 2.5V reference, eliminating the need for external components. The device operates from a single +5V supply and supports parallel data output via latched three-state buffers. Key electrical parameters include a typical conversion time of 2µs, a maximum sampling rate of 400kS/s, and a total unadjusted error of ±1/2 LSB. It functions within a temperature range of 0°C to +70°C and is housed in a 24-pin Wide SO package.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a complete data acquisition system with a multiplexer, track/hold circuit, and internal voltage reference.
• Employs a half-flash conversion technique to achieve high-speed 8-bit resolution without requiring an external clock.
• Features simplified microprocessor interfacing through memory-mapped or I/O port compatibility using only Chip Select and Read control inputs.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix 'T' corresponds to tape-and-reel packaging as specified by the manufacturer's documentation. Confirm the component status and availability directly with Analog Devices or authorized distributors, as lead times and stock levels fluctuate. Ensure the specific grade matches the required operational temperature range for the intended application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a compact, single-supply solution for multi-channel signal digitization is required. The integrated reference and track/hold simplify board layout compared to discrete alternatives. Verify that the source impedance of the driving circuitry remains low enough to meet the 1µs acquisition time requirements for accurate conversion results.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX154/MAX158 family of high-speed ADCs. While the MAX154 provides four channels, the MAX158 variant offers eight channels. Both share identical core architectures and performance characteristics, differing primarily in channel count and pin assignments. This series represents a legacy product line from Maxim Integrated, now part of Analog Devices.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes within the same package and specification profile are not explicitly listed in the provided documentation. Designers should evaluate newer generations of ADCs from Analog Devices for improved performance metrics, ensuring interface compatibility and pinout mapping are addressed during migration.
