Texas Instruments High-Performance Analog Integrated Circuits (ICs) - Data Acquisition - ADCs-DACs - Special Purpose LDC1000NHRJ

The LDC1000NHRJ is an inductance-to-digital converter designed for high-resolution inductive sensing applications. It operates in a supply voltage range of 4.75 V to 5.25 V for analog and 1.8 V to 5.25 V for I/O, with a supply current of 1.7 mA when not using an LC tank. The device features a 16-bit resolution for R_P measurements and a 24-bit resolution for L measurements, making it suitable for precise applications such as position and motion sensing, as well as in medical devices and consumer electronics. This product supports a frequency range of 5 kHz to 5 MHz and utilizes a contact-less sensing technology that is resilient to environmental factors such as dust, dirt, and moisture. The LDC1000NHRJ is packaged in a compact WSON format, measuring 5.00 mm x 4.00 mm, which facilitates remote sensor placement in harsh environments. It also includes a serial peripheral interface (SPI) for easy integration with microcontrollers. However, it is important to note that this part number is marked as obsolete, which may affect availability for new designs.
