TI LDC131x/161x for Multichannel Inductive Sensing
Texas Instruments has introduced the world's first multichannel inductance-to-digital converters (LDCs). The four new devices – the LDC1312, LDC1314, LDC1612 and LDC1614 – offer two or four matched channels and up to 28-bit resolution in a single integrated circuit (IC).
- Multiple, well-matched channels
- Precision measurement capability (up to 28-bit resolution)
- Sensor frequency range 1 kHz to 10 MHz
- Low system power: ~6.9 mW during standard operation; 0.12 mW in shutdown mode
- Contactless sensing is immune to nonconductive contaminants
Product Description
Unlike other technologies, LDC-enabled inductive sensing employs low-cost, high-reliability inductors as sensors, which can be located remotely from the IC.
With the dual-channel LDC1312 and LDC1612 devices and the quad-channel LDC1314 and LDC1614 devices, system design can become much simpler while also improving cost effectiveness. By integrating up to four channels in a single IC, the LDC1614 family allows designers to distribute sensors throughout a system, while centralising electronics on fewer printed circuit boards (PCBs).
This can benefit precision linear or rotational sensing and metal detection in a wide range of products including white goods, printers, cameras and automotive infotainment consoles.
Power consumption has been lowered across the LDC family to benefit battery-operated applications. The supply voltage has been dropped from 5.0V to 3.3V, reducing consumption in active mode from 8.5 mW to 6.6 mW. Standby-mode power consumption has dropped from 1.25 mW to 0.11 mW. Additionally, the new LDC family features a pin for shutdown mode, during which the device consumes only 0.2 µA.
