PGA308AIDGST

Sensor And Detector Interfaces Overview

The PGA308AIDGST is a single-supply, auto-zero sensor amplifier manufactured by Texas Instruments. It operates within a voltage range of 2.7 V to 5.5 V and supports a maximum supply voltage of 5.5 V. The device features a single channel with an input bias current of 100 pA. It is housed in a 10-MSOP package (also designated as 10-VSSOP) and is designed for surface-mount installation. The component functions across an extended temperature range from -40°C to +125°C. As part of the PGA308 series, it serves as a programmable analog sensor signal conditioner.

Sensor And Detector Interfaces Feature Summary

• Integrates auto-zero technology to minimize offset and drift errors in sensor signal paths.
• Provides digital calibration capabilities for gain and offset adjustments via a 1-wire interface.
• Includes onboard one-time programmable memory for storing calibration parameters.

Sensor And Detector Interfaces Applications

• Signal conditioning for bridge sensors
• Programmable analog sensor interfaces
• Single-supply measurement systems

Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the required operating temperature range and supply voltage constraints before integration. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents.

Sensor And Detector Interfaces Selection Notes

Select this component when a single-channel, low-bias-current amplifier with integrated digital calibration is required. Compare against the PGA309 if additional channels or different packaging options are needed. Verify that the 10-MSOP footprint fits the target PCB layout and that the 1-wire programming interface aligns with the system's control architecture.

Sensor And Detector Interfaces Part Context

The PGA308AIDGST belongs to the PGA308/309 family of programmable sensor signal conditioners. These devices are designed to simplify the interface between sensors and microcontrollers by providing amplification and digital calibration in a single IC. The PGA308 specifically offers a single-channel configuration suitable for applications requiring precise signal conditioning without external calibration components.

Sensor And Detector Interfaces Replacement Considerations

PGA308AIDGSR is a reel-based alternative within the same series. PGA308AIDGSRG4 is a lead-free variant. Verify pinout and electrical specifications match before substitution.
