Introduction

AI Translation

The TDC1000 is a fully integrated ultrasonic sensing analog front-end (AFE) commonly used in liquid level, liquid identification/concentration, flow, and proximity/remote sensing applications. When used in conjunction with MSP430/C2000 MCUs, power supplies, wireless networks, and source code, it provides a complete ultrasonic sensing solution. It is programmable and flexible, suitable for a wide range of applications and end devices. It can be configured for various transmit pulses and frequencies, gains, and signal thresholds for use with multiple sensor frequencies (31.25 kHz to 4 MHz) and Q factors. The receive path is programmable, enabling the detection of ultrasonic waves propagating through various media over longer distances/larger tank sizes. Different operating modes can be selected, and it is optimized for low power consumption, making it an ideal choice for battery-powered flow meters, liquid level gauges, and distance/proximity sensing measurement devices. The low-noise amplifier and comparator generate extremely low jitter, enabling picosecond-level resolution and accuracy for zero and low flow measurements.
