Circuit compensates optocoupler temperature
coefficient: 11/22/2001 EDN - Design Ideas /
When using an optocoupler in a linear application,
you should consider its gain drift with temperature.
Traditional single- and dual-transistor-output
devices have a notable gain drift with temperature.
In recent years, some temperature-compensated
optocouplers have appeared. However, another option
is to use two optocouplers or a dual optocoupler
with appropriate feedback to make the dri... . |

Optocoupler simplifies power line monitoring:
01/10/2002 EDN - Design Ideas / The use of a linear
optocoupler and a capacitor-based power supply
yields a simple, yet precise power-line-monitoring
system. The circuit in Figure 1 converts the 110V-ac
power-line voltage to an ac output voltage centered
at 2.5V, covering 0 to 5V. The circuit isolates the
output signal from the power line. . |
Optocouplers are handy for motor drive:
06/13/2002 EDN - Design Ideas / Figure 1a shows a
latching circuit based on an optocoupler, IC1. If
the off switch remains closed, pressing the on
switch powers the LED in the optocoupler. Thus, the
transistor in IC1 turns on. You can now release the
on switch, and the transistor remains on. You must
adapt the current-limiting resistor, R, to the
power-supply voltage and the optocoupler's
characteristics.. |
