PGA308AIDGSRG4

Sensor And Detector Interfaces Overview

The PGA308AIDGSRG4 is a single-channel, 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 consumes 1.6 mA of supply current. It is housed in a 10-VSSOP (MSOP-10) surface-mount package with a width of 3.00 mm. The component functions as a programmable analog signal conditioner, integrating digital calibration capabilities for offset and gain adjustments via a 1-Wire interface.

Sensor And Detector Interfaces Feature Summary

• Integrates a single-channel auto-zero amplifier with programmable gain and digital offset/gain calibration capabilities.
• Features a 1-Wire UART-compatible serial interface for programming gain and offset parameters into onboard OTP memory.
• Supports direct connection to three-terminal sensor modules, allowing programming through the Vout pin.

Sensor And Detector Interfaces Applications

• Signal conditioning for bridge sensors requiring precise offset and gain correction.
• Programmable analog front-end circuits for industrial sensor interfaces.
• Applications utilizing three-terminal sensor modules where programming is performed via the output pin.

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix RG4 against the manufacturer's datasheet to confirm RoHS compliance and lead-free status. Confirm that the MSOP-10 package dimensions match the design footprint requirements. Check for moisture sensitivity level (MSL 2) handling precautions during assembly. Ensure the 1-Wire interface compatibility aligns with the host microcontroller or controller system specifications.

Sensor And Detector Interfaces Selection Notes

Select this component when a single-channel solution with integrated auto-zeroing and digital calibration is required. Consider the PGA309 if logic-level inputs or additional channels are needed. Verify that the 1-Wire interface constraints fit the system architecture. Evaluate the 10-VSSOP package size against available PCB real estate. Confirm that the 2.7 V to 5.5 V supply range matches the system power rails.

Sensor And Detector Interfaces Part Context

The PGA308 belongs to the PGA30x family of programmable sensor signal conditioners designed for high-precision applications. It is part of Texas Instruments' portfolio of sensor interface ICs that combine analog amplification with digital calibration. The device simplifies sensor signal processing by reducing the need for external calibration components and complex software routines.

Sensor And Detector Interfaces Replacement Considerations

PGA308AIDGSR is listed as a manufacturer-recommended alternative. Verify if the non-RG4 suffix differs in packaging or environmental compliance. No other direct substitutes are confirmed in the provided documentation.
