Short-Circuit Currents
Short circuits to ground, positive or negative power supply
are allowed as long as the power supplies do not exceed
±5V and the ambient temperature stays below 85˚C.
Above ±5V and at elevated temperatures, continuous
Each building block of the LTC1060, together with an
external clock and a few resistors, closely approximates
2nd order filter functions. These are tabulated below in the
frequency domain.

short circuits to the negative power supply will cause
excessive currents to flow. Under these conditions, the
device will get damaged if the short-circuit current is
allowed to exceed 80mA.
