7.4.1 Inputs

The TLV7081 input extends from V- to 5.6 V which is independent of supply. The input IN can be any voltage within these limits and no phase inversion of the comparator output occurs.

The input of TLV7081 is fault tolerant. It maintains the same high input impedance when V+ is unpowered or ramping up. The input can be safely driven up to the specified maximum voltage (5.6 V) with V+ = 0 V or any value up to the maximum specified.

The input bias current is typically 3 pA for input IN voltages between 0 and 5.6 V. The comparator inputs are protected from undervoltage by internal diodes connected to V-. As the input voltage goes under V-, the protection diodes become forward biased and begin to conduct causing the input bias current to increase exponentially. Input bias current typically doubles for every 10°C temperature increase.
