DESCRIPTION
The LEADCHIP A8290 is a high-voltage adjustable current source with accurate temperature compensation.
The device is designed to provide a constant current source determined by an external sense resistor R .
SENSE The current is adjustable from 10mA to 20mA with less than 10% error while input changes from 5V to 90V.
With an external resistor (R1 in Figure 1) between VA and IS pin, the heat in the IC can be significantly reduced while keeping the summation of IC and R1 current to be constant.
This is extremely useful in the area that power lines are not very stable.
A typical application for the...
