OPA3680
FIGURE 15. Internal ESD Protection.
INPUT AND ESD PROTECTION
The OPA3680 is built using a very high speed complemen-
tary bipolar process. The internal junction breakdown volt-
ages 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
15.
These diodes provide moderate protection to input overdrive
voltages above the supplies as well. The protection diodes
can typically support 30mA continuous current. Where higher
currents are possible (e.g., in systems with
±
15V supply
parts driving into the OPA3680), current-limiting series
resistors should be added into the two inputs. Keep these
resistor values as low as possible since high values degrade
both noise performance and frequency response.
