4.3

Rail-to-rail input

The TSV52x series are guaranteed without phase reversal as shown in Figure 28.

It is extremely important that the current flowing in the input pin does not exceed 10 mA.

Rail-to-rail output

The operational amplifiers output levels can go close to the rails: 35 mV maximum above

and below the rail when connected to a 10 k

4.5

Driving resistive and capacitive loads

To drive high capacitive load, adding in series resistor at the output can improve the stability

of the device (see Figure 29 for recommended in series value). Once the in series resistor

has been selected, the stability of the circuit should be tested on bench and simulated with

in series resistor create a voltage divider introducing an error proportional to the ratio
