The q denotes specifications which apply over the specified
temperature range.
Note 1: The analog inputs (pins 1, 3 for the LT1203, pins 1, 3, 5, 7 for the
LT1205) are protected against ESD and overvoltage with internal SCRs.
For inputs ≤ ±2.8V the SCR will not fire. Voltages above 2.8V will fire the
SCR and the DC current should be limited to 20mA. To turn off the SCR
the pin voltage must be reduced to less than 1V or the current reduced to
less than 600µA.
