... LFSCP_VQ (ADA4817-2) 64 MAXIMUM SAFE POWER DISSIPATION The maximum safe power dissipation for the ADA4817-1/ ADA4817-2 are limited by the associated rise in junction temperature ( the die. At approximately 150°C (which is J the glass transition temperature), the properties of the plastic change. Even temporarily exceeding this temperature limit may change the stresses that the package exerts on the die, permanently shifting the parametric performance of the ADA4817-x ...

... Supply current and offset current are laser trimmed for optimum performance. These specifications make the ADA4817-1/ ADA4817-2 a great choice for high speed instrumentation and high resolution data acquisition systems. Its low noise, picoamp input current, precision offset, and high speed make them superb preamps for fast photo- diode applications ...

... The V temperature drift is below 8 μV/°C; therefore, it can change up to 0.3 mV due to warm-up effects for an ADA4817-1/ADA4817 LFCSP The input bias current increases by a factor of 1.7 for every 10°C rise in temperature. ...

... Due to package variations and pin-to-pin parasitics between the single and the dual models, the ADA4817-2 has a little more peaking then the ADA4817-1, especially at a gain of 2. The best way to tame the peaking is to place a feedback capacitor across the feedback resistor. Figure 46 shows the small signal frequency response of the ADA4817 gain ...

... EXPOSED PADDLE The ADA4817-1/ADA4817-2 feature an exposed paddle, which lowers the thermal resistance by 25% compared to a standard SOIC plastic package. The exposed paddle of the ADA4817-1/ ADA4817-2 floats internally which provides the maximum flexibility and ease of use. It can be connected to the ground plane or to the negative power supply plane. In cases where thermal heating is not an issue, the exposed pad can be left floating ...

... Poor PCB layout, contaminants, and the board insulator material can create leakage currents that are much larger than the input bias current of the ADA4817-1/ADA4817-2. Any voltage differential between the inputs and nearby runs sets up leakage currents through the PCB insulator, for example 100 GΩ ...

... The current equivalent noise from the inverting terminal is typically negligible for most applications. The innovative architecture used in the ADA4817-1/ADA4817-2 makes balancing both inputs unnecessary, as opposed to traditional FET input amplifiers. Therefore, minimizing the impedance seen from the noninverting terminal to ground at all frequencies is critical for optimal noise performance ...
