MAX154BCWG+

Analog To Digital Converters (ADC) Overview

The MAX154BCWG+ is a CMOS high-speed analog-to-digital converter featuring four single-ended analog input channels and an integrated multiplexer. It provides 8-bit resolution with a typical conversion time of 2.0µs per channel, supporting a maximum sampling rate of 400kS/s across all channels. The device operates from a single +5V supply and includes an internal 2.5V reference output. It utilizes a half-flash architecture and offers parallel CMOS data outputs via latched three-state buffers. The component is housed in a 24-pin Wide SO package and supports an operating temperature range of 0°C to +70°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CWG+' against the manufacturer's current ordering guide to confirm the package type and accuracy grade. Confirm RoHS compliance status as indicated in the latest datasheet revision. Ensure the intended application environment remains within the specified commercial temperature limits of 0°C to +70°C for this particular variant.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a multi-channel acquisition system requires high speed without external multiplexers or references. Compare the 8-bit resolution and 400kS/s aggregate throughput against requirements. Verify that the single-ended input range matches the signal source characteristics before finalizing the design.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX154/MAX158 family of high-speed ADCs manufactured by Analog Devices / Maxim Integrated. The MAX154 variant specifically provides four analog inputs, whereas the MAX158 variant offers eight channels. Both share identical core conversion architectures and timing specifications.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX154ACWG+ serves as a functional alternative within the same series, offering similar performance characteristics but potentially differing in accuracy specifications or manufacturing lot details. Verify pinout compatibility and electrical parameters before substitution.
