TI Sensing InnovationDelivering better solutions today and new possibilities for tomorrow

Sensing is all around us. Designing with sensors presents various challenges as each sensor is different and requires a specific signal chain. Texas Instruments’ analog portfolio provides solutions to speed the design cycle with the right signal acquisition solutions. TI’s portfolio includes precision amplifiers and data converters providing accuracy and speed conditioning, sensor front-ends making the bridge between the sensor and the microcontroller, and connectivity products to interface the sensor. In addition, the WEBENCH Sensor Designer tool significantly reduces design time and cost by configuring a complete sensor signal path solution with just a few clicks.

Capacitive sensing with grounded capacitors is a high-resolution, low-cost, contactless sensing technique that can be applied to a variety of applications. The sensor in a capacitive sensing system is any conductor, allowing for a low-cost and highly-flexible system design. The FDC1004 is a 4-channel capacitance-to-digital converter designed for capacitive sensing applications. It features more than 16-bit effective noise-free resolution and provides compensation of up to 100 pF offset capacitance to accommodate the use of remote sensors. The FDC1004 also includes two strong drivers for sensor shields to allow focusing of sensing direction and to reduce EMI interference.

The LM57 is a precision, dual-output, temperature switch with integrated analog temperature sensor. The trip temperature (TTRIP) is programmable by using two external 1% resistors. Using extremely-small packaged resistors (0.5 mm x 1 mm), the LM57 can be programmed to any of 256 trip temperatures while consuming very little board space. The VTEMP output delivers an analog output voltage which is proportional with a negative temperature coefficient (NTC) to the measured temperature.

Features

  • Low 1.5 V operation
  • Very accurate: ±0.4°C typical
  • Wide temperature range of -50°C to 150°C
  • Low 5.4µA quiescent current
  • Average sensor gain of -5.5 mV/°C
  • LMT84-Q1 is AEC-Q100 Grade 0 qualified and is manufactured on an automotive grade flow

LM20 - 2.4 V, 10 µA, SC70, micro SMD Temperature Sensor

LM20XEVM LM20XEVM-ND EVALUATION BOARD FOR LM20X Datasheet

The LM20 is a precision analog output CMOS integrated-circuit temperature sensor that operates over a −55°C to 130°C temperature range. The power supply operating range is 2.4 V to 5.5 V. The transfer function of LM20 is predominately linear, yet has a slight predictable parabolic curvature. The accuracy of the LM20 when specified to a parabolic transfer function is ±1.5°C at an ambient temperature of 30°C. The temperature error increases linearly and reaches a maximum of ±2.5°C at the temperature range extremes.

Features

  • Rated for full −55°C to +130°C range
  • Available in an SC70 and DSBGA package
  • Predictable curvature error
  • Suitable for remote applications
