PGA309ASPWT

Sensor And Detector Interfaces Overview

The PGA309ASPWT is a voltage output programmable sensor conditioner from Texas Instruments, designed for high-precision signal conditioning. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an extended industrial temperature range from -55°C to +150°C. The device features a single channel with an input bias current of 100 pA. It is housed in a TSSOP-16 surface-mount package. This component belongs to the PGA309-HT series, indicating its suitability for harsh environments requiring wide thermal stability.

Sensor And Detector Interfaces Feature Summary

• Integrated programmable sensor signal conditioning for bridge sensors
• Extended high-temperature operation capability up to 150°C
• Low input bias current for minimal signal loading

Sensor And Detector Interfaces Applications

• Bridge sensor signal conditioning
• High-temperature industrial measurement systems
• Precision sensor interface circuits

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix ASPWT against official Texas Instruments documentation to confirm the HT (high-temperature) grade and TSSOP-16 packaging. Ensure compatibility with system voltage limits of 5.5 V maximum and operating temperatures up to 150°C. Cross-reference datasheet revision dates to confirm parameter consistency before integration.

Sensor And Detector Interfaces Selection Notes

Select this part when application requirements demand operation beyond standard industrial ranges, specifically up to 150°C. Compare against the standard PGA309AIPWR if lower temperature tolerance (-40°C to 125°C) suffices, as it may offer different availability or cost structures. Confirm that the 5.5 V absolute maximum rating aligns with the power supply design.

Sensor And Detector Interfaces Part Context

The PGA309ASPWT is part of the PGA309 family of sensor conditioners. It shares core functionality with variants like the PGA309AIPWR but differs in environmental ratings. The 'HT' designation typically signifies enhanced thermal performance compared to standard commercial or industrial grade counterparts within the same product line.

Sensor And Detector Interfaces Replacement Considerations

The PGA309AIPWR serves as a related variant within the same family. Note that the AIPWR version has a limited operating temperature range of -40°C to 125°C, which is narrower than the ASPWT's -55°C to 150°C specification. Substitution requires verifying that the reduced thermal headroom meets the target application's environmental constraints.
