JAJSVI0H December 2001 – October 2024 OPA690
PRODUCTION DATA
The OPA690 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 Section 6.1. All device pins are protected with internal ESD protection diodes to the power supplies. Figure 7-3 shows the internal ESD protection.
These diodes also provide moderate protection to input overdrive voltages greater than the supplies. The protection diodes can typically support 10 mA of continuous current. Where higher currents are possible (for example, in systems with ±15-V supply parts driving into the OPA690), add current-limiting series resistors into the two inputs. Keep these resistor values as low as possible, because high values degrade both noise performance and frequency response.
