The XTR105TDC2 is a CMOS/TDC sensor interface, a product of Intersil Corporation. It is designed to interface with sensors that measure a physical phenomenon such as position, motion, pressure, temperature, etc. The XTR105TDC2 enables easy cabling, signal condition, and data conversion of a sensor’s output. This makes it the ideal choice for customers looking for a simple, low-cost, efficient solution for applications involving sensors.

Application Fields of XTR105TDC2

The XTR105TDC2 is designed for use in applications that require measurement of a physical phenomenon, such as:

• Position sensing
• Altitude or pressure sensing
• Temperature sensing
• Flow or transducer sensor measurement
• Motion control

The XTR105TDC2 can be used in any application requiring a low-cost, low-power, reliable, and accurate sensing platform. These applications include automotive, medical, industrial, and consumer electronics.

Working Principle of XTR105TDC2

The XTR105TDC2 is an analog-to-digital converter with Time-to-Digital Conversion (TDC) capability. It uses linear-ramp technology to provide a high-accuracy, low-power solution for multi-point data conversion. It is designed to interface directly with any type of linear or rotary position or motion sensor, such as optical encoders, potentiometers, Hall effect sensors, and strain gages.

The XTR105TDC2 includes two linear-ramp tracks, each with a resolution of 1 ns. These two tracks can be used for both up-down and up/down comparisons. This allows the XTR105TDC2 to be used for position sensing applications that use multiple-point data acquisition such as motor encoders and flow-rate sensors.

When used for position sensing, the XTR105TDC2 uses the two linear-ramp tracks to compare the changing voltage of the sensor to a voltage reference on each track. When the voltage reference is exceeded, the XTR105TDC2 generates a digital output pulse which can be read by an attached microcontroller.

For motion control applications, the XTR105TDC2 can also be used to measure velocity and acceleration. In these applications, the XTR105TDC2 uses the two linear-ramp tracks to measure the changes in rate. This allows the XTR105TDC2 to be used for controlling the speed and acceleration of a motor or other actuator.

In summary, the XTR105TDC2 is a low-cost, low-power, reliable, and accurate sensor interface. It is designed for use in any application that requires the measurement of a physical phenomenon and is ideal for applications involving sensors such as position, motion, pressure, temperature, etc.
