ADS1286PG4

Overview

The ADS1286PG4 is a 12-bit micro-power sampling analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a successive approximation architecture and features a single analog input channel. The device operates within an extended temperature range of -40°C to +85°C and is housed in an 8-pin PDIP package. Key electrical specifications include a maximum conversion time of 60 µs, a maximum linear error of 0.0244%, and support for analog input voltages up to 5.3 V. The component is RoHS compliant and lead-free.

Feature Summary

• Micro-power consumption design suitable for battery-operated applications
• Successive approximation architecture for efficient data conversion
• Single-channel differential or single-ended input capability
• Extended industrial temperature rating for robust operation

Applications

• Portable medical instrumentation requiring low power consumption
• Industrial process control systems with sensor interfaces
• Battery-powered measurement devices

Procurement Notes

Verify the specific package type and temperature grade against project requirements before procurement. Confirm that the 8-pin PDIP form factor aligns with existing PCB footprints. Ensure compatibility with the required operating voltage ranges and interface protocols. Check for any specific ordering suffixes that may indicate different packaging or environmental certifications. Validate compliance with current regulatory standards such as RoHS.

Selection Notes

Select this component when a 12-bit resolution is sufficient for the application's accuracy needs. Consider the micro-power characteristics if energy efficiency is a primary constraint. Evaluate the PDIP package availability against assembly capabilities. Compare performance metrics such as linearity and conversion speed against alternative ADC architectures. Ensure the single-channel requirement matches the system design without needing multiplexing.

Part Context

The ADS1286PG4 belongs to the ADS1286 family of 12-bit micro-power sampling ADCs from Texas Instruments. This series is designed for applications demanding low power consumption and moderate precision. The PG4 suffix typically indicates a lead-free and RoHS-compliant variant of the standard ADS1286 part. It serves as a cost-effective solution for basic data acquisition tasks where high-speed conversion is not critical.

Replacement Considerations

Direct replacements include other variants within the ADS1286 family, such as the ADS1286U or ADS1286UB, provided the package difference is accommodated. Cross-reference with similar 12-bit SAR ADCs from other manufacturers only if pinout and electrical specifications are fully compatible.
