The Texas Instruments (TI) 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 a TI
MSP430/C2000 MCU, power, wireless, and source code, the combo 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, says the company.
