15 / 38 page  After the device enters the saturation region, the charge carriers in the output transistors require time to return to the linear state. After the charge carriers return to the linear state, the device begins to slew at the specified slew rate. Therefore, the propagation delay (in case of an overload condition) is the sum of the overload recovery time and the slew time. The overload recovery time for the LM290xLV-Q1 family is typically 1 µs. 7.3.4 Electrical Overstress Designers often ask questions about the capability of an operational amplifier to withstand electrical overstress. These questions tend to focus on the device inputs, but can also involve the supply voltage pins. Each of these different pin functions has electrical stress limits determined by the voltage breakdown characteristics of the particular semiconductor fabrication process and specific circuits connected to the pin. Additionally, internal electrostatic discharge (ESD) protection is built into these circuits to protect them from accidental ESD events both before and during product assembly. Having a good understanding of this basic ESD circuitry and its relevance to an electrical overstress event is helpful. Figure 7-1 shows the ESD circuits contained in the LM290xLV-Q1. The ESD protection circuitry involves several current-steering diodes connected from the input and output pins and routed back to the internal power supply lines, where they meet at an absorption device internal to the operational amplifier. This protection circuitry is intended to remain inactive during normal circuit operation. + ± V + V± +IN ± IN OUT Power Supply ESD Cell Figure 7-1.

The Figure 6-28 plot illustrates the performance of the LM290xLV-Q1 family's EMI filters across a wide range of frequencies.

The devices are powered on as long as the power- supply voltage is between 2.7 V (±1.35 V) and 5.5 V (±2.75 V). www.ti.com LM2902LV-Q1, LM2904LV-Q1 SBOS987B – AUGUST 2020 – REVISED OCTOBER 2021 Copyright © 2021 Texas Instruments Incorporated Submit Document Feedback 15 Product Folder Links: LM2902LV-Q1 LM2904LV-Q1 |
