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

LDC1312EVM — 適用於電感轉數位轉換器且具有樣本 PCB 線圈的 LDC1312 評估模組

LDC1312 評估模組展示可用於感測和測量導電性目標是否存在的電感感測技術。評估模組包括兩個範例 PCB 感測器線圈，連接至 LDC1312 的四個通道，並且使用 MSP430 微控制器將 LDC 介接至主機電腦。

此模組旨在為使用者提供最大的彈性，以進行系統原型設計。LDC1312EVM 在兩個位置有穿孔：

PCB 感測器線圈（LC 諧振電路）和 LDC1312 之間
LDC1312 和 MSP430 介面之間

第一個穿孔可讓使用者選擇從模組中拆下 PCB 線圈，並使用自訂感測器線圈進行實驗，第二個穿孔則可讓使用者將 LDC1312 (...)
