INPUT AND ESD PROTECTION
The OPA695 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 de-
vices. These breakdowns are reflected in the Absolute Maxi-
mum Ratings table where an absolute maximum ±6.5V
supply is reported. All device pins have limited ESD protec-
tion using internal diodes to the power supplies, as shown in
Figure 19.
These diodes also provide moderate protection to input
overdrive voltages above the supplies. The protection diodes
can typically support 30mA continuous current. Where higher
currents are possible (for example, in systems with ±15V
supply parts driving into the OPA695), 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.
