Product Overview
The LDC1612 is a Texas Instruments inductance-to-digital converter categorized as a Sensor component. It is specified as a 2-channel device with 28-bit conversion resolution, supporting inductive sensing with sensor frequencies from 1 kHz to 10 MHz. The sensing capability is stated as beyond two coil diameters, making the device applicable to target-distance inductive sensing arrangements based on coil geometry.
The device operates from a recommended 2.7 V to 3.6 V supply and is rated for operation from -40 C to 125 C ambient temperature. Typical supply current is 2.1 mA, not including sensor current, with fCLKIN at 10 MHz. Low-power states include sleep mode at 35 uA typical and shutdown mode at 0.2 uA typical when SD is tied to VDD.
The LDC1612 is supplied in a WSON-12 package with a nominal 4 mm x 4 mm body size. Interface and control details include I2C address selection at 0x2A for ADDR low and 0x2B for ADDR high. The shutdown pin must not float; SD low selects normal operation and SD high selects inactive mode.
