... 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 photodiode applications ...

... The V temperature drift is below 12 μV/°C; therefore, it can change 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. Heavy loads increase power dissipation and raise the chip junction temperature as described in the Absolute Maximum Ratings section ...

... CAPACITIVE FEEDBACK Due to package variations and pin-to-pin parasitic between the single and the dual, 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. ...

... 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 could 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 designer does not need to use the dedicated feedback pin to provide feedback for the ADA4817-1/ADA4817-2. The output pin of the ADA4817-1/ADA4817-2 can still be used to provide feedback to the inverting input of the ADA4817-1/ADA4817-2. WIDEBAND PHOTODIODE PREAMP The wide bandwidth and low noise of the ADA4817-1/ ...

... 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 ...

... With a 410 MHz gain bandwidth product and high slew rate, the ADA4817-1/ADA4817 ideal candidate for active filters. Moreover, thanks to the low input bias current provided by the FET stage, the ADA4817-1/ADA4817-2 eliminate any dc errors. Figure 48 shows the frequency response of 90 MHz and 45 MHz LPFs. In addition to the bandwidth requirements, the slew rate must be capable of supporting the full power band- width of the filter ...
