555 timer circuit temperature sensor temperature

555 timer is a combination of analog and digital functions in scale integrated devices. Usually made with bipolar process called 555, with the CMOS process is referred to 7555,
555 timer circuit temperature sensor temperature - schematic

in addition to single timer, there are corresponding dual timer 556/7556 Wide supply voltage range 555 timer can be 4.5V ~ 16V work, 7555 can work 3 ~ 18V, output drive current of about 200mA, so its output can be, CMOS analog circuits or compatible with TTL level in at. Low cost, reliable performance, requires only a few external resistors, capacitors, you can achieve multivibrator, Schmitt trigger, and a single-shot pulse generation and conversion circuits, etc.
