OPA2890
SBOS364A – DECEMBER 2007 – REVISED DECEMBER 2007
The OPA2890 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 63.
Figure 63. Internal ESD Protection
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 (for example, in systems with ±15V supply
parts driving into the OPA2890), 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.
