because high values degrade both noise performance
and frequency response.
INPUT AND ESD PROTECTION
The OPA2673 is built using a high-speed
complementary bipolar process. The internal junction
breakdown voltages are relatively low for these very
small geometry devices and are reflected in the
Absolute Maximum Ratings table. All device pins
have limited ESD protection using internal diodes to
the power supplies, as shown in Figure 87.
