NOTE:
1. All currents are in RMS unless otherwise noted.
2. 12V VPP is supported for a maximum of 100 cycles and may be connected for up to 10 cumulative hours.
3. Operating current is a linear function of operating frequency and voltage. Operating current can be calculated using
the formula shown with operating frequency (f) expressed in MHz and operating voltage (V) in volts.
Example: When operating at 2 MHz at 2V, the device will draw a typical active current of 0.8*2* 2 = 3.2mA in the page
access mode. This parameter is specified with the outputs disabled to avoid external loading effects. The user must
add current required to drive output capacitance expected in the actual system.
