1. CHARACTERISTICS AND SPECIFICATIONS

(All Min/Max characteristics and specifications are guaranteed over the Specified Operating Conditions. Typical

performance characteristics and specifications are derived from measurements taken at typical supply voltages

and TA = 25°C.)

Notes:

1. Operation beyond these limits may result in permanent damage to the device.

Normal operation is not guaranteed at these extremes.

2. Any pin except supplies. Transient currents of up to ±100 mA on the analog input pins will not cause

SCR latch-up.

3. The maximum over/under voltage is limited by the input current.
