PGA308AQDGSRQ1

Sensor And Detector Interfaces Overview

The PGA308AQDGSRQ1 is a single-supply, auto-zero sensor amplifier designed for programmable analog signal conditioning. It features a one-wire UART-compatible interface for digital calibration of offset and gain. The device includes seven memory banks in on-board one-time programmable (OTP) memory, with four programming cycles available after power-on reset. Operating within a voltage range of 2.7 V to 5.5 V, it supports a maximum supply voltage of 5.5 V and operates between -40°C and +125°C. Packaged in a 10-MSOP (VSSOP) case, it has an input bias current of 1.5 nA and draws 1.6 mA of supply current. It is AEC-Q100 qualified for automotive applications.

Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and temperature grade. Confirm that the component meets AEC-Q100 requirements if intended for automotive use. Check for moisture sensitivity level compliance during storage and handling procedures as indicated in the datasheet.

Sensor And Detector Interfaces Selection Notes

Select this component when a single-supply, digitally calibrable sensor amplifier is required for bridge sensors. Ensure the application environment falls within the specified -40°C to +125°C operating range. Verify that the 10-MSOP package fits the PCB layout constraints and that the one-wire interface compatibility matches the system controller.

Sensor And Detector Interfaces Part Context

The PGA308AQDGSRQ1 belongs to the PGA308/PGA309 family of programmable sensor signal conditioners from Texas Instruments. It is specifically designed for applications requiring precise analog signal conditioning with digital calibration capabilities. The 'AQ' suffix indicates automotive qualification and extended temperature range, while 'DGSR' denotes the MSOP package and tape-and-reel shipping method.

Sensor And Detector Interfaces Replacement Considerations

The PGA308AIDGSRQ1 is a non-automotive qualified version of the same device family. Verify if automotive qualification is strictly required before substituting. Other PGA308 variants may differ in package or temperature rating; consult the official datasheet for pinout and electrical specification comparisons.
