This circuit rejects frequencies around 1 kHz and can be adjusted using C1. Equivalent operational amplifiers can be used, and the power supply must be symmetrical.
The sampling and retention circuits are used in analog to digital converters and in some other...
Launched in early 1999, the new ADC12181 high-speed A / D converter is suitable for applications...
This circuit can use NTCs from 200 to 680 ohms, just change P2. For 200 ohms use 330 ohms, for 250...
