OPA2690
SBOS238D − JUNE 2002 − REVISED DECEMBER 2004
INPUT AND ESD PROTECTION
The OPA2690 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 19.

Circuitry
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 OPA2690),
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.
