MAX154ACNG+

Analog To Digital Converters (ADC) Overview

The MAX154ACAG+ is an 8-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It features four single-ended analog input channels and utilizes a half-flash architecture for conversion. The device operates from a single +5V supply with a typical power dissipation of 75 mW. It includes a built-in track/hold function and an internal 2.5V reference, eliminating the need for external components. The ADC provides a parallel CMOS data interface and supports a maximum sampling rate of 400 kS/s. It is housed in a 24-pin SSOP package and functions within a temperature range of 0°C to +70°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm the specific AC suffix indicates ±1/2 LSB error specification and industrial temperature range. Check datasheet revisions for updates on electrical characteristics. Ensure proper handling procedures are followed during installation.

Analog To Digital Converters (ADC) Selection Notes

Select this model when four-channel acquisition is required with integrated reference capabilities. Compare against the MAX158 if eight channels are needed. Verify that the 400 kS/s sampling rate meets system bandwidth requirements. Ensure the single-ended input configuration aligns with sensor output types.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX154/MAX158 family of CMOS high-speed ADCs. The MAX154 variant specifically provides four analog inputs, whereas the MAX158 offers eight. Both share identical conversion speeds and architectural features, differing primarily in channel count and pin assignments for address lines.
