Introduction

AI Translation

The LDC1312-Q1 and LDC1314-Q1 are 2-channel and 4-channel 12-bit inductance-to-digital converters (LDC) respectively, designed for inductive sensing solutions. With multi-channel support and remote sensing capability, the LDC1312-Q1 and LDC1314-Q1 deliver high-performance, reliable inductive sensing at minimal cost and power consumption. These devices are easy to use — simply ensure the sensor frequency falls within the 1kHz to 10MHz range to begin operation. The wide supported sensor frequency range of 1kHz to 10MHz also enables the use of very small PCB coils, further reducing the cost and size of the sensing solution.

The LDC1312-Q1 and LDC1314-Q1 feature well-matched channels for differential and ratiometric measurements. This allows designers to use one channel to compensate for environmental and aging conditions during sensing, such as temperature, humidity, and mechanical drift. Thanks to their ease of use, low power consumption, and low system cost, these devices help designers significantly improve existing sensing solutions, enabling new sensing capabilities in products across all markets — particularly consumer and industrial applications. Compared to similar sensing technologies, inductive sensing offers higher performance, reliability, and flexibility, with lower system cost and power consumption.

The LDC1312-Q1 and LDC1314-Q1 are easily configured via the I2C interface. The 2-channel LDC1312-Q1 is available in a WSON-12 package, and the 4-channel LDC1314-Q1 is available in a WQFN-16 package.
