Feature Description (continued)
7.3.5 Input and ESD Protection
The OPA376 family incorporates internal electrostatic discharge (ESD) protection circuits on all pins. In the case
of input and output pins, this protection primarily consists of current steering diodes connected between the input
and power-supply pins. These ESD protection diodes also provide in-circuit, input overdrive protection, as long
as the current is limited to 10 mA as stated in the Absolute Maximum Ratings. Figure 24 shows how a series
input resistor may be added to the driven input to limit the input current. The added resistor contributes thermal
noise at the amplifier input and its value should be kept to a minimum in noise-sensitive applications.

7.4 Device Functional Modes
The OPAx376 has a single functional mode and is operational when the power-supply voltage is greater than
2.2 V (±1.1 V). The maximum power supply voltage for the OPAx376 is 5.5 V (±2.75 V).
