TDC1000PW

Sensor And Detector Interfaces Overview

The TDC1000PW is an ultrasonic sensing analog front-end (AFE) integrated circuit manufactured by Texas Instruments. It is designed to drive ultrasonic transducers and process received echo signals for time-of-flight measurements. The device operates on a single 3.3 V supply and features a digital output interface. It is housed in a 28-pin Thin Shrink Small Outline Package (TSSOP) with a width of 4.40 mm. The component supports surface mount installation and functions within a temperature range of -40°C to +125°C. It draws approximately 5 mA of supply current.

Sensor And Detector Interfaces Feature Summary

• Integrated analog front-end specifically engineered for ultrasonic sensing applications
• Capable of driving ultrasonic transducers and processing received echo signals
• Provides digital output interface for direct connection to microcontrollers or time-to-digital converters

Sensor And Detector Interfaces Applications

• Ultrasonic distance measurement systems
• Liquid level sensing applications
• Object detection and proximity sensing

Sensor And Detector Interfaces Procurement Notes

Verify the specific package variant, as the TDC1000PWR denotes tape-and-reel packaging while the TDC1000PW indicates tube packaging. Confirm that the 28-TSSOP footprint matches the target PCB design. Ensure the operating temperature range meets the environmental requirements of the final assembly. Check for RoHS compliance status prior to ordering.

Sensor And Detector Interfaces Selection Notes

Select this component when designing ultrasonic sensors requiring a dedicated AFE for signal conditioning. It pairs effectively with Time-to-Digital Converters like the TDC7200 for precise flight-time calculations. Consider the TDC1000PWR if high-volume manufacturing requires reel-based assembly processes instead of tube handling.

Sensor And Detector Interfaces Part Context

The TDC1000 belongs to the TDC1000 family of ultrasonic sensing AFEs from Texas Instruments. It is commonly used in conjunction with the TDC7200 Time-to-Digital Converter to form a complete ultrasonic ranging solution. This combination allows for accurate distance measurement in various industrial and consumer applications.

Sensor And Detector Interfaces Replacement Considerations

The TDC1000PWR serves as a functional equivalent with identical electrical characteristics but utilizes tape-and-reel packaging instead of tubes. Verify pin compatibility and software configuration requirements when substituting between these packaging variants.
