The TDC1011 is a fully integrated analog front-end (AFE) for ultrasonic sensing measurements of liquid level, fluid identification/concentration, and proximity/ distance applications common in automotive, industrial, medical, 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 TDC1011 can be configured for multiple transmit pulses and frequencies, gain, and signal thresholds for use with a wide-range of transducer frequencies (31.25kHz to 4MHz) 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 TDC1011 can be optimized for low power consumption, making it ideal for battery powered applications. The low noise amplifiers and comparators provide extremely low jitter, enabling picosecond resolution and accuracy.
