 显示了当PD引脚在禁用和启用状态之间切换时OPA858的瞬态响应。PD禁用和启用阈值电压参考负电源。如果放大器的正电源配置为3.3 V，负电源配置为接地，则禁用和启用阈值电压分别为0.65 V和1.8 V。如果放大器配置了±1.65-V电源，则禁用和启用阈值电压分别为–1 V和0.15 V。如果放大器配置有±2.5V电源，则阈值电压为–1.85 V和–0.7 V。图54显示了当PD引脚从启用状态向下扫描到禁用状态时典型放大器的开关行为。类似地，图55显示了当PD引脚从禁用状态向上扫描到启用状态时典型放大器的开关行为。下扫和上扫之间切换阈值的微小差异是由于放大器中设计的滞后，以提高其对PD引脚上噪声的抗扰度。图54.切换阈值（PD引脚从高电平扫描到低电平）图55.切换阈值。当放大器被配置为非反相放大器时，反馈（RF）和增益（RG）电阻器网络形成到show the transient response of the OPA858 as the PD pin toggles between the disabled and enabled states. The PD disable and enable threshold voltages are with reference to the negative supply. If the amplifier is configured with the positive supply at 3.3 V and the negative supply at ground, then the disable and enable threshold voltages are 0.65 V and 1.8 V, respectively. If the amplifier is configured with ±1.65-V supplies, then the disable and enable threshold voltages are at –1 V and 0.15 V, respectively. If the amplifier is configured with ±2.5-V supplies, then the threshold voltages are at –1.85 V and –0.7 V. Figure 54 shows the switching behavior of a typical amplifier as the PD pin is swept down from the enabled state to the disabled state. Similarly Figure 55 shows the switching behavior of a typical amplifier as the PD pin is swept up from the disabled state to the enabled state. The small difference in the switching thresholds between the down sweep and the up sweep is due to the hysteresis designed into the amplifier to increase its immunity to noise on the PD pin.

Switching Threshold (PD Pin Swept from LOW to HIGH) Connecting the PD pin low disables the amplifier and places the output in a high-impedance state. When the amplifier is configured as a noninverting amplifier, the feedback (RF) and gain (RG) resistor network form a parallel load to the output of the
