Texas Instruments TDC1011 Ultrasonic Sensing Analog Front End (AFE)
Texas Instruments TDC1011 Ultrasonic Sensing Analog Front End (AFE) is a fully integrated analog front-end (AFE) for ultrasonic sensing measurements. This can used for liquid level, fluid identification/concentration, and proximity/distance applications. When paired with an MSP430/C2000 MCU, power, wireless, and source code, they provide the complete ultrasonic sensing solution. This device offers programmability and flexibility to accommodate a wide-range of applications and end equipment. The TDC1011 from Texas Instruments can be configured for multiple transmit pulses and frequencies, gain, and signal thresholds. This can be uses with a wide-range of transducer frequencies (31.25kHz to 4MHz) and Q-factors. The programmability of the receive path allows ultrasonic waves to be detected over a wider range of distances/tank sizes and through various mediums.
