TDC1011PWR

Sensor And Detector Interfaces Overview

The TDC1011PWR is a time-to-digital converter (TDC) from Texas Instruments designed for high-resolution distance measurement applications. It features a 12-bit resolution with a typical time resolution of 50 ps, enabling precise measurements over a range up to 4 meters. The device integrates a pulse generation circuit and a time-to-digital conversion engine, operating on a single 3.3 V supply. It utilizes an I2C-compatible serial interface for configuration and data readout. Packaged in a 16-pin TSSOP, it supports operation across a temperature range of -40°C to +85°C.

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix PWR indicates the TSSOP-16 package variant when sourcing. Confirm that the component meets AEC-Q100 or other relevant qualification standards if required for automotive or harsh environment deployments. Ensure the ordering part number matches the exact pinout and thermal specifications documented in the official datasheet to avoid compatibility issues during assembly.

Sensor And Detector Interfaces Selection Notes

Select this component when sub-nanosecond timing precision is required for ultrasonic-based distance measurements. Compare against competitors based on power consumption at 3.3 V operation and the integration level of the internal pulse generator. Evaluate the I2C interface speed requirements against the host microcontroller capabilities to ensure seamless data acquisition without additional buffering hardware.

Sensor And Detector Interfaces Part Context

This device belongs to Texas Instruments' family of time-to-digital converters optimized for ultrasonic applications. It complements other analog front-end solutions by providing the digital timing core necessary for converting acoustic echo delays into digital values. Its design focuses on reducing external component count by integrating critical timing functions directly onto the silicon die.

Sensor And Detector Interfaces Replacement Considerations

Direct replacements are limited due to the specific integration of the pulse generator and TDC engine. Verify pin-to-pin compatibility with alternative TI models such as the TDC1000 series if architectural differences in the analog front end are acceptable. Cross-reference timing resolution and supply voltage requirements strictly before substitution.
