Temperature-to-Bits: One IC for All Sensor Types, 0.1°C Conformity
07.21.2016 · Articles
Temperature measurement is not new. Galileo invented a rudimentary thermometer capable of detecting temperature changes, and two hundred years later, Seebeck discovered the thermocouple. Given the long history of temperature measurement and its extensive use today, one would think that accuracy problems were all but eliminated. Not so...

Amplifier IC Generates a Negative Voltage Reference with the Fewest Parts and a Single Supply Rail
07.18.2016 · Circuits
Certain applications require the use of a negative voltage reference, which is usually not readily available. A common way to generate a negative voltage has been to use an operational amplifier (op amp) to invert the output of a positive precision voltage reference. This approach typically requires a positive reference, the op amp, and two supply rails to generate the negative output...
FTDI's Pioneering Arduino-Compatible Touch-Enabled Display Shield Starts Shipping

FTDI Chip will also give engineers complete access to a comprehensive development resource, which has step-by-step tutorials and projects, plus a series of software tools...
Lowpass, 30-kHz Bessel filter offers high performance for audio applications
07.14.2016 · Circuits
Thanks to its property of applying an equal amount of delay to all frequencies below its cutoff frequency, the Bessel linear-phase filter sees service in audio applications in which it's necessary to remove out-of-band noise without degrading the phase relationships of a multifrequency in-band signal. In addition, the Bessel filter's fast step response and freedom from overshoot or ringing make it an excellent choice as a smoothing filter for an audio DAC's output or as an antialiasing filter for an audio ADC's input...
