EL Frequency
The EL lamp frequency is controlled via an external resistor
connected between REL pin and VDD pin of the device. As
the lamp frequency increases, the resistor value decreases.
For resistor value selections, see the “Typical Character-
istics: EL Frequency vs. EL Resistor” or use the equation
below. The EL frequency range is 60Hz to 1000Hz, with an
accuracy of ±20%.
Micrel
In general, as the EL lamp frequency increases, the amount
of current drawn from the battery will increase. The color
of the EL lamp and the intensity are dependent upon its
frequency.

The enable function of the MIC4826 is implemented by switch-
ing the R SW and R EL resistor between ground and V DD . When
R SW and R EL are connected to ground, the switch and the
EL oscillators are disabled; therefore the EL driver becomes
disabled. When these resistors connect to V DD , both oscilla-
