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 600 µA. |
