PGA308AIDRKR

Sensor And Detector Interfaces Overview

The PGA308AIDRKR is a single-supply auto-zero sensor amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an operating temperature range from -40°C to +125°C. The device features a 100 pA input bias current and utilizes a VSON-10 surface-mount package. It functions as a programmable analog sensor signal conditioner, integrating digital calibration for offset and gain via a 1-Wire interface.

Sensor And Detector Interfaces Feature Summary

• Integrates a single-supply auto-zero sensor amplifier with programmable gain capabilities.
• Provides digital calibration for offset and gain errors using onboard one-time programmable memory.
• Features a 1-Wire UART-compatible interface for configuration and parameter storage.

Sensor And Detector Interfaces Applications

• Signal conditioning for three-terminal sensor modules
• Industrial process control systems requiring precise sensor data acquisition
• Automotive sensor interfaces demanding wide temperature operation

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix 'KR' against official Texas Instruments documentation to confirm tape-and-reel specifications and moisture sensitivity levels. Ensure compatibility with existing PCB footprints for the VSON-10 package during procurement planning.

Sensor And Detector Interfaces Selection Notes

Select this component when designing circuits that require integrated auto-zeroing to minimize drift in low-level sensor signals. Consider the VSON-10 package constraints and the availability of 1-Wire programming resources if hardware simplicity is prioritized over parallel interfaces.

Sensor And Detector Interfaces Part Context

This part belongs to the PGA308 family of programmable analog front ends designed for sensor applications. It consolidates amplification, filtering, and digital calibration into a single IC, reducing the bill of materials compared to discrete solutions.

Sensor And Detector Interfaces Replacement Considerations

Direct pin-to-pin replacements within the same family include PGA308AIDRKT and PGA308AIDGSR. Verify package differences (VSON vs MSOP) and suffix variations before substitution.
