The TDC1000 is a fully integrated analog front-end (AFE) for ultrasonic sensing measurements of level, fluid identification/concentration, and proximity/distance applications common in automotive, industrial, and consumer markets. When paired with an MSP430/C2000 MCU, power, wireless, and source code, TI provides the complete ultrasonic sensing solution.

TI’s Ultrasonic AFE offers programmability and flexibility to accommodate a wide-range of applications and end equipment. The TDC1000 can be configured for multiple transmit pulses and frequencies, gain, and signal thresholds for use with a wide-range of transducer frequencies (31.25 kHz to 4 MHz) and Q-factors. Similarly, the programmability of the receive path allows ultrasonic waves to be detected over a wider range of distances/tank sizes and through various mediums.

Selecting different modes of operation, the TDC1000 can be optimized for low power consumption for battery-powered flow meters, level instrumentation, and distance/proximity measurements. The low noise amplifiers and comparators provide extremely low jitter, enabling picosecond resolution and accuracy for zero and low flow measurements.
