PGA460TPWQ1

Sensor And Detector Interfaces Overview

The PGA460TPWQ1 is an automotive-grade analog front-end (AFE) and ultrasonic signal processor designed for proximity sensing applications. It integrates a low-noise amplifier, programmable time-varying gain stage, and a 12-bit ADC operating at an 8 MS/s sampling rate. The device features a single-channel input and supports multiple communication interfaces including 1-Wire, TCI, and UART/USART. It operates within a supply voltage range of 6 V to 28 V and functions reliably across a temperature range of -40°C to +105°C. Housed in a 16-pin TSSOP package, it meets AEC-Q100 qualification standards for automotive electronics.

Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets the required AEC-Q100 grade for automotive deployment. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Sensor And Detector Interfaces Selection Notes

Select this component for designs requiring integrated signal conditioning and driving capabilities for ultrasonic transducers. Consider the 16-pin TSSOP footprint for PCB layout constraints. Verify interface compatibility with the host controller, as the device supports TCI, 1-Wire, and UART protocols. Ensure the system power supply aligns with the specified 6 V to 28 V operating range.

Sensor And Detector Interfaces Part Context

The PGA460TPWQ1 belongs to the PGA460 family of ultrasonic signal processors from Texas Instruments. It is specifically engineered for automotive environments, offering high integration by combining the analog front-end, DSP, and transducer driver into a single system-on-chip solution. This integration reduces external component count and simplifies design complexity for proximity sensing applications.

Sensor And Detector Interfaces Replacement Considerations

Consult the PGA460 datasheet for officially listed alternative part numbers or pin-compatible substitutes. Verify that any replacement maintains the same automotive qualification status and interface compatibility.
