Convertidor de señal de tiempo a digital (TDC) TDC7200

Texas Instruments TDC7200 Time-to-Digital Converter (TDC) is for ultrasonic sensing measurements such as water flow meter, gas flow meter, and heat flow meter. When paired with the TDC1000 (ultrasonic analog-front-end), the TDC7200 can be a part of a complete ultrasonic sensing solution that includes the MSP430, power, wireless, and source code. The TDC7200 performs the function of a stopwatch and measures the elapsed time (time-of-flight) between a START pulse and up to five STOP pulses. The ability to measure from START to multiple STOPs gives users the flexibility to select which STOP pulse yields the best echo performance. The device has an internal self-calibrated time base which compensates for drift over time and temperature. Self-calibration enables time-to-digital conversion accuracy in the order of picoseconds. This accuracy makes the TDC7200 ideal for flow meter applications, where zero and low flow measurements require high accuracy.
