ADS1282SJDJ

Overview

The ADS1282SJDJ is a high-temperature, ultra-high-resolution delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a 31-bit resolution and supports two ADC channels with a sampling rate of 4 kS/s. The device utilizes an SPI interface and is housed in a 28-pin CDIP package. It operates within an analog supply voltage range of 4.75 V to 5.25 V and is designed for applications requiring high accuracy, including seismic and energy exploration.

Feature Summary

• Integrated low-noise programmable gain amplifier
• Two-channel input multiplexer
• Inherently-stable modulator with fast response

Applications

• Seismic data acquisition systems
• Energy exploration equipment
• High-precision industrial measurement

Procurement Notes

Verify the specific suffix JDJ indicates the 28-lead ceramic dual in-line package (CDIP). Confirm that the component meets the required high-temperature operational specifications for your application environment. Ensure compatibility with existing SPI communication protocols and power supply requirements before integration.

Selection Notes

Select this component when ultra-high resolution and high-temperature stability are critical. The integrated PGA reduces external component count. Consider the 4 kS/s sampling rate against system bandwidth needs. Verify package availability and lead times for specialized ceramic packaging options.

Part Context

This part belongs to the ADS1282-HT series, designed for extreme performance environments. It shares architectural similarities with other delta-sigma ADCs but distinguishes itself through high-temperature capability and ceramic packaging suitable for harsh conditions.

Replacement Considerations

ADS1282SJDJ is a specific variant. Direct substitutes may include other high-temperature delta-sigma ADCs from Texas Instruments or competitors offering similar resolution and package types, provided pinout and electrical characteristics match.
