MAX11254ATJ/V+

Analog To Digital Converters (ADC) Overview

The MAX11254ATJ/V+ is a 6-channel, 24-bit delta-sigma analog-to-digital converter (ADC) from Analog Devices. It features a low-noise programmable gain amplifier (PGA) with gains from 1x to 128x and supports sample rates up to 64ksps. The device operates on a single 2.7V to 3.6V analog supply or split ±1.8V supplies, with a digital supply of 1.7V to 3.6V. Key electrical parameters include an SNR of 133dB at 50sps and 124dB at 1000sps. It communicates via SPI, is housed in a 5mm x 5mm TQFN-32 package, and is qualified under AEC-Q100 for automotive applications.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix '/V+' indicates AEC-Q100 qualification status. Confirm the package type matches the required TQFN-32 footprint. Ensure the voltage ratings align with the target application's supply rails. Check for RoHS compliance documentation. Validate that the component is sourced from authorized distributors to guarantee authenticity.

Analog To Digital Converters (ADC) Selection Notes

Select this ADC when high resolution and low noise are critical for precision DC measurements. Consider the PGA gain settings if signal conditioning is required before digitization. Evaluate the data rate requirements against the available SPI interface speed. Verify compatibility with the system's logic voltage levels for reliable communication.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX11254 family of high-performance delta-sigma ADCs. It shares core architecture with other variants in the series but differs in qualification and packaging options. The /V+ suffix specifically denotes automotive-grade reliability standards. It serves as a bridge between analog sensor signals and digital processing units in demanding environments.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family should be verified against the official datasheet. Substitutes must match the 24-bit resolution and 6-channel configuration. Ensure the alternative part supports the required SPI interface and operating temperature range.
