LTC6258 Low Power Squarewave - Sinewave Oscillator

Aug 30th 2017
A low power sine wave generator can be derived by driving a square wave into the bandpass filter. A complete schematic is shown in Figure 4a. The LTC6992-1 easily configures as a 50% duty cycle 10kHz square wave, and can drive the relatively benign loading seen in the bandpass filter. Figures 4b and 4c show the LTC6992-1 output ...

Temperature To Frequency Converter

Jan 30th 2001
This circuit directly converts temperature to digital data. In this case, a thermistor sensor biases the RSET pin. The LTC1799 frequency output is predictable, although nonlinear. The inverse RSET vs frequency relationship combines with the thermistor’s nonlinear characteristic to give Figure 8’s data. The curve is nonlinear, ...
