Overload recovery

Overload recovery is defined as the time required for the op amp output to recover from a

saturated state to a linear state.

The saturation state occurs when the output voltage gets very close to either rail in the

application. It can happen due to an excessive input voltage or when the gain setting is too

high.

When the output of the TSZ182 enters in saturation state it needs 10 µs to get back to a

linear state as shown in Figure 58: "Negative overvoltage recovery VCC = 5 V" and Figure

59: "Positive overvoltage recovery VCC = 5 V".

Figure 36: "Negative overvoltage recovery VCC = 2.2 V" and Figure 37: "Positive

overvoltage recovery VCC = 2.2 V" show the overvoltage recovery for a VCC = 2.2 V.

Figure 58: Negative overvoltage recovery VCC = 5 V

Figure 59: Positive overvoltage recovery VCC = 5 V
