ADS1274IPAPT

Analog To Digital Converters (ADC) Overview

The ADS1274IPAPT is a quad-channel, 24-bit simultaneous-sampling analog-to-digital converter (ADC) from Texas Instruments. It utilizes a delta-sigma architecture and operates with a maximum sampling rate of 144 kS/s per channel. The device features an SNR of 111 dB and supports single-ended inputs via an SPI interface. It requires a 4.75 V to 5.25 V analog supply and a 1.65 V to 2.2 V digital supply. Packaged in a 64-pin HTQFP, it functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Provides four independent channels for simultaneous signal acquisition.
• Supports daisy-chaining for multi-device system expansion.
• Integrates high-resolution 24-bit data conversion capabilities.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems
• Precision data acquisition modules
• Vibration monitoring equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature grade. Ensure compatibility with required analog and digital voltage rails during component sourcing. Confirm moisture sensitivity level handling procedures are available for the HTQFP-64 package before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this model when four synchronized channels are required at high resolution. Compare power consumption against thermal constraints in enclosed industrial enclosures. Verify that the external reference requirement aligns with system accuracy goals.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS127x family of precision ADCs. It shares architectural similarities with the ADS1278 but offers four channels instead of eight. Both devices utilize the same 64-pin HTQFP package and similar performance metrics.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS1278IPAPT serves as a compatible alternative offering eight channels with identical sampling rates and packaging. Verify pinout compatibility and software register mapping differences before substitution.
