Feature Description (continued)

7.3.1.7 Wide Voltage Range

The LMC7101 is characterized at 15 V, 5 V and 3 V. Performance data is provided at these popular voltages.

This wide voltage range makes the LMC7101 a good choice for devices where the voltage may vary over the life

of the batteries.

7.4 Device Functional Modes

7.4.1 Input Common Mode

7.4.1.1 Voltage Range

The LMC7101 does not exhibit phase inversion when an input voltage exceeds the negative supply voltage.

Figure 61 shows an input voltage exceeding both supplies with no resulting phase inversion of the output.

The absolute maximum input voltage is 300-mV beyond either rail at room temperature. Voltages greatly

exceeding this maximum rating, as in Figure 62, can cause excessive current to flow in or out of the input pins,

thus adversely affecting reliability.

An input voltage signal exceeds the LMC7101 power supply

A ±7.5-V input signal greatly exceeds the 3-V supply in Figure 63

voltages with no output phase inversion.

Figure 62. Input Signal

Applications that exceed this rating must externally limit the maximum input current to ±5 mA with an input

resistor as shown in Figure 63.
