Division circuit diagram

Published:2011/8/19 1:50:00 Author:Jessie | Keyword: Division

As shown in figure: A1 forms Voltage controlled current source, A2is thevoltage comparator, A3 is the active low-pass filter. When time constant R1C1 equals to clock pulse cycle T, the relationship between input and output of circuit is: Vo=-V2E/V1. If make E = 1V, there were Vo=-V2/V1. V1 and V2 are required to bepositive, limited in 10V, the V2 is slightly below V1. Resistance R1, R2 and capacitance C1 required tousethe components with goodtemperature stability. A1 is HA2-2520,A2, A3 are LM101A.   (View)

Cold shutoff temperature control circuit with TWH9205

Published:2011/8/26 2:14:00 Author:Jessie | Keyword: cold shutoff, temperature control

As shown in figure, this circuit is composedofthe zero switch control circuit composedof TW9205 andits peripheral components, SCR drive refrigeration control circuit and sound circuit. The temperature sensor RT in graph uses negative temperature coefficient (NTC) thermal resistor, which is connected to the differential switch amplifier reversed-phase input terminal(pin 9) of TWH9205; Differential switch amplifier phase input terminal(pin 13) and potential clamp fixed end pin 10, 11. Adjust RP1's value so that TWH9205 in set temperature range outputs a low level, and SCR VS in a globe state. When thermistors RT increases to a predetermined value with the temperature, output state of differential switch amplifier is inside the TWH9205, an output terminal of the TWH9205 sents to the high level whenAC powerbecomes zero, SCR VS connected, appliancesget electricity and work.   (View)

MC1496 multiplication circuit diagram

Published:2011/8/19 1:39:00 Author:Jessie | Keyword: multiplication

When the circuit selects Rx = 30kΩ, Ry = 62kΩ, I1 = 0.5mA, K = 1 / 10, the output voltage Vo is Vo = VxVy/10 Since the output current Io is inverted by inverting amplifier, so the X-Vx is added to x- end, this is because positive selection of the right side decision; if the right side is selected as negative, the input signal should be added to the X + side. In order to prevent parasitic oscillation, the input end of Vx and Vy is connected 470Ω 10pF network in series.   (View)
