R_OSC
Oscillator Resistor
A resistor from this pin to circuit ground determines the operating frequency of the
oscillator. The 33794 is optimized for operation around 120 kHz.
40
CLK
Clock
This pin provides a square wave output at the same frequency as the internal
oscillator. The edges of the square wave coincide with the peaks (positive and
negative) of the sine wave.

V
DD
Monitor
This is connected through a voltage divider to V
DD
. It allows reduction of the
voltage so it will fall within the range of the ADC on the MCU.

Capacitor
A capacitor is connected to this pin to filter the internal analog regulated supply.
This supply is derived from V
PWR
.

V
PWR
Positive Power Supply Input
12 V power applied to this pin will be converted to the regulated voltages needed
to operate the part. It is also converted to 5.0 V (V
CC
) and 8.5 V (V
DD
) to power
the MCU and external devices.
