7.3.2 Input and ESD Protection
The OPA2810 is built using a very high-speed complementary bipolar process. The internal junction breakdown
voltages are relatively low for these very small geometry devices. These breakdowns are reflected in the
Absolute Maximum Ratings table. All device pins are protected with internal ESD protection diodes to the power
supplies as shown in Figure 3.
These diodes provide moderate protection to input overdrive voltages above the supplies as well. The protection
diodes can typically support 30-mA continuous current. Where higher currents are possible (for example, in
systems with ±12-V supply parts driving into the OPA2810), current limiting series resistors should be added into
the two inputs. Keep these resistor values as low as possible because high values degrade both noise
performance and frequency response.
