产品说明

The LDC1312 and LDC1314 are 2- and 4-channel, 12-bit inductance to digital converters (LDCs) for inductive sensing solutions. With multiple channels and support for remote sensing, the LDC1312 and LDC1314 enable the performance and reliability benefits of inductive sensing to be realized at minimal cost and power. The products are easy to use, only requiring that the sensor frequency be within 1 kHz and 10 MHz to begin sensing. The wide 1 kHz to 10 MHz sensor frequency range also enables use of very small PCB coils, further reducing sensing solution cost and size.

The LDC1312 and LDC1314 offer well-matched channels, which allow for differential and ratiometric measurements. This enables designers to use one channel to compensate their sensing for environmental and aging conditions such as temperature, humidity, and mechanical drift. Given their ease of use, low power, and low system cost these products enable designers to greatly improve on existing sensing solutions and to introduce brand new sensing capabilities to products in all markets, especially consumer and industrial applications. Inductive sensing offers better performance, reliability, and flexibility than competitive sensing technologies at lower system cost and power.

The LDC1312 and LDC1314 are easily configured via an I2C interface. The two-channel LDC1312 is available in a WSON-12 package and the four-channel LDC1314 is available in a WQFN-16 package.
