AFE General Purpose 28-Pin TSSOP T/R

The TDC1011-Q1 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,Ultrasonic AFE offers programmability and flexibility to accommodate a wide-range of applications and end equipment. The TDC1011-Q1 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-Q1 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.
