Texas Instruments provides a recommended PCB layout in the LDC1000QPWRQ1 evaluation module (EVM) user's guide, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
The LDC1000QPWRQ1 requires a one-time calibration process to set the internal oscillator frequency and gain. This can be done using the provided calibration software and a known inductor value. The calibration process is described in the device's user's guide.
While the datasheet specifies a frequency range of 1 kHz to 100 kHz, the LDC1000QPWRQ1 can actually operate up to 200 kHz with reduced accuracy. However, it's recommended to operate within the specified range for optimal performance.
While the LDC1000QPWRQ1 is primarily designed for inductive sensing, it can be used for capacitive sensing applications with some modifications to the sensor design and signal processing. However, it's essential to consult with Texas Instruments' application engineers to ensure feasibility and optimal performance.
The LDC1000QPWRQ1 has a sleep mode that reduces power consumption to approximately 10 μA. This mode can be enabled by setting the appropriate register bits, and it's useful for battery-powered applications where power consumption needs to be minimized.
