Capacitive-Digital Converter Delivers Reliable Gesture Sensing


Capacitive-Digital Converter Delivers Reliable Gesture Sensing
ON Semiconductor
January 17, 2017

The LC717A30UJ capacitance-to-digital converter uses mutual capacitance to detect changes in capacitance down to femtofarad (fF) levels. Parasitic capacitance cancellation raises the detector sensitivity, while its built-in noise rejection mechanism combats the effects of electromagnetic interference (EMI). The eight capacitance-sensing input channels make the LC717A30UJ highly optimized for use in systems where an array of switches is required. The device includes an integrated multiplexer for input channel selection, analog-to-digital converter, dual-stage amplifier that determines capacitance changes plus outputs analog amplitude values, system clock, power-on reset circuit, and all the necessary control logic to create a total solution. Both I2C and SPI interfaces are selectable based on the system application needs.

As the device’s sensitivity has a range of 150 mm, its higher sensitivity enables gesture motions as well as offering conventional touch functionality, thereby enhancing users’ control options to address a wide range of application scenarios. In addition, it is capable of operating with an airgap between the sensor/PCB and the protective cover. This device also includes an integrated automatic calibration function, which optimizes and self-calibrates total capacitance according to electrode, line capacitance, and surrounding environment.

The LC717A30UJ is offered in a SSOP-30 package and priced at $1.05 each/10,000 unit quantities. A datasheet is available at http://www.onsemi.com/PowerSolutions/product.do?id=LC717A30UJ

Low-Cost RF Switches Optimize Transceiver Performance


Low-Cost RF Switches Optimize Transceiver Performance
California Eastern Laboratories (CEL)
January 17, 2017

CEL is introducing a variety of RF switches that perform as drop in replacements for a wide range of existing RF products and new designs. Target markets include test and measurement systems as well as Wi-Fi, ZigBee and Bluetooth routers, sensors, appliances, and other radio-equipped products. Typical options include:
• Single-pole-double-throw (SPDT or 1:2) switches that route signals from one input to two output paths.
• Multiport or single-pole-multiple-throw (SPnT) switches that allow a single input to multiple (three or more) output paths.
• Double-pole-double-throw (DPDT) switches can be used to switch between two inputs and two outputs

The switches operate over frequency ranges through 6 GHz and are drop-in compatible to various existing Renesas RF switches. Some of these new switches include:
• CG2179MT (SPDT) general purpose RF switch
• CG2214M6 (SDPT) general purpose RF switch with low insertion loss
• CG2185X2 (SPDT) compact wideband RF switch for WLAN applications
• CG2163X3 (SPDT) Wideband RF switch for WLAN providing high isolation features
• CG2415M6 (SPDT) Wideband RF switch for WLAN that features medium power and high isolation
• CG2430X1 (SP3T) Wideband RF switch for WLAN and Bluetooth
• CG2176X3 (Absorptive SPDT) High Power, Wideband RF Switch for WLAN

TIs’ Time-to-Digital Converter Now Available


TIs’ Time-to-Digital Converter Now Available
Texas Instruments Inc.
January 17, 2017

Mouser Electronics, Inc. is now stocking the TDC7201 time-to-digital converter from Texas Instruments (TI). The device is designed for use with ultrasonic, laser, and radar range finding equipment using time-of-flight (TOF) technique. It integrates two time-to-digital converters (TDCs) that can be used to measure distance down to 4 cm and up to several kilometers using a simple architecture, which eliminates the need to use FPGAs or processors. The chip performs the function of a stopwatch and measures the TOF between a START pulse and up to five STOP pulses. This ability to measure simultaneously and individually on two pairs of pins using two built-in TDCs offers great flexibility in time measurement design. Other features include a measurement range of 0.25 ns to 8 ms and an accuracy of 28 ps. The device has a single shot resolution of 55 ps, (equivalent to 0.825 cm).
