Texas Instruments LDC1312DNTT
The LDC1312 and LDC1314 are 2- and 4-channel, 12-bit inductance todigital converters (LDCs) for inductive sensing solutions. With multiple channels and support forremote sensing, the LDC1312 and LDC1314 enable the performance and reliability benefits ofinductive sensing to be realized at minimal cost and power. The products are easy to use, onlyrequiring that the sensor frequency be within 1 kHz and 10 MHz to begin sensing. The wide 1 kHz to10 MHz sensor frequency range also enables use of very small PCB coils, further reducing sensingsolution cost and size.
The LDC1312 and LDC1314 offer well-matched channels, which allow fordifferential and ratiometric measurements. This enables designers to use one channel to compensatetheir sensing for environmental and aging conditions such as temperature, humidity, and mechanicaldrift. Given their ease of use, low power, and low system cost these products enable designers togreatly improve on existing sensing solutions and to introduce brand new sensing capabilities toproducts in all markets, especially consumer and industrial applications. Inductive sensing offersbetter performance, reliability, and flexibility than competitive sensing technologies at lowersystem cost and power.
The LDC1312 and LDC1314 are easily configured via an I2C interface. Thetwo-channel LDC1312 is available in a WSON-12 package and the four-channel LDC1314 is available ina WQFN-16 package.
