TDC1000PWR

用于液位和浓度感应的超声波感应模拟前端 28-TSSOP -40 to 125

The TDC1000 is a fully integrated analog front-end AFE for ultrasonic sensing measurements of level, fluid identification/concentration, flow, and proximity/ distance applications common in automotive, industrial, medical, and consumer markets. When paired with an MSP430/C2000 MCU, power, wireless, and source code, 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 31.25kHz 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 TDC1000 can be optimized for low power consumption, making it ideal 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.
