LIMITING VALUES

In accordance with the Absolute Maximum Rating System (IEC 134); VDDD =VDDA = 3 V; all voltages measured with

respect to ground; Tamb =25 °C; unless otherwise specified.

Notes

1. All VDD and VSS connections must be made to the same power supply.

2. Equivalent to discharging a 100 pF capacitor via a 1.5 k

Ω series resistor.

3. Equivalent to discharging a 200 pF capacitor via a 2.5

µH series inductor.
