Texas Instruments TDC7200PWR Time-to-Digital Converter

The TDC7200PWR is a sophisticated time-to-digital converter (TDC) integrated circuit, designed and manufactured by Texas Instruments. This high-precision device is capable of time measurement with picosecond resolution, making it a crucial component in a wide range of applications such as ultrasonic flow meters, laser range finders, and time-of-flight mass spectrometry.

At the heart of the TDC7200PWR lies its ability to measure time intervals with extreme accuracy. The device features two measurement channels, which can measure time intervals from a start pulse to a stop pulse, with the start and stop events being on the same channel or on separate channels. This flexibility allows for a variety of measurement configurations and enhances the device's utility across different applications.

The TDC7200PWR boasts an impressive measurement range from 12 ns to 8 ms, with a resolution of 55 ps in the normal resolution mode and 275 ps in the high resolution mode. This range and precision enable the device to cater to applications that require very fine time measurements. Additionally, the TDC7200PWR is equipped with an automatic calibration feature that compensates for variations in temperature and voltage, ensuring stable and accurate measurements over time.

This time-to-digital converter operates on a supply voltage ranging from 2.7V to 5.5V, which allows for integration into systems with varying power requirements. The TDC7200PWR also features a low-power consumption mode, which is particularly beneficial for battery-powered applications where energy efficiency is critical.

The TDC7200PWR is available in a small 14-pin TSSOP package, making it suitable for space-constrained applications. Its interface is SPI-compatible, ensuring easy communication with microcontrollers and other digital systems. Engineers and designers will appreciate the ease of integration and the robust feature set that the TDC7200PWR offers, making it a versatile choice for precision time interval measurement solutions.
