... When the VCC voltage is below the minimum supply voltage, the VSW pin is in high impedance. Therefore, current conducts directly from the input power source to the output through the inductor and diode. Once VCC reaches approximately 1.5 V, the internal power switch briefly turns on.

... The control circuit is built around a 14 pin CD40106 Hex Schmitt Trigger chip, but only four of its six identical elements are actually used. In the diagram they are numbered from 1 to 4 for reference purposes. A feature of the device is that the output of each trigger is at either 0v or 12v; never ...

InstruTECH ITC-18 16-bit Multi-Channel Data Acquisition Interface
... The ITC-18 provides eight analog input channels. Each input channel uses an 18-bit A/D converter preceded by a programmable gain stage. Each A/D input can be programmed with a full scale range of ±1, ±2, ±5, or ±10 Volts. This gain stage reduces the need for external signal amplifiers before the ...

Schmitt trigger
In electronics a Schmitt trigger is a comparator circuit with hysteresis implemented by applying positive feedback to the noninverting input of a comparator or differential amplifier. It is an active circuit which converts an analog input signal to a digital output signal. The circuit is named a ""trigger"" because the output retains its value until the input changes sufficiently to trigger a change. In the non-inverting configuration, when the input is higher than a chosen threshold, the output is high. When the input is below a different (lower) chosen threshold the output is low, and when the input is between the two levels the output retains its value. This dual threshold action is called hysteresis and implies that the Schmitt trigger possesses memory and can act as a bistable multivibrator (latch or flip-flop). There is a close relation between the two kinds of circuits: a Schmitt trigger can be converted into a latch and a latch can be converted into a Schmitt trigger.Schmitt trigger devices are typically used in signal conditioning applications to remove noise from signals used in digital circuits, particularly mechanical contact bounce. They are also used in closed loop negative feedback configurations to implement relaxation oscillators, used in function generators and switching power supplies.
