sgm8061/2/3 application notes driving capacitive loads the sgm806x family is optimized for bandwidth and speed, not for driving capacitive loads. output capacitance will create a pole in the amplifier?s feedback path, leading to excessive peaking and potential oscillation. if dealing with load capacitance is a requirement of the application, the two strategies to consider are (1) using a small resistor in series with the amplifier?s output and the load capacitance and (2) reducing the bandwidth of the amplifier?s feedback loop by increasing the overall noise gain. figure 1 shows a unity gain follower using the series resistor strategy. the resistor isolates the output from the capacitance and, more importantly, creates a zero in the feedback path that compensates for the pole created by the output capacitance. v in v out sgm8061 c load r iso figure 1 . series resistor isolating capacitive load power-supply bypassing and layout the sgm806x family operates from either a single +2.7v to +5.5v supply or dual 1.35v to 2.75v supplies. for single-supply operation, bypass the power supply v dd with a 0.1 f ceramic capacitor which should be placed close to the v dd pin. for dual-supply operation, both the v dd and the v ss supplies should be bypassed to ground with separate 0.1 f ceramic capacitors. 2.2 f tantalum capacitor can be added for better performance. good pc board layout techniques optimize performance by decreasing the amount of stray capacitance at the op amp?s inputs and output. to decrease stray capacitance, minimize trace lengths and widths by placing external components as close to the device as possible. use surface-mount components whenever possible. for the high speed operational amplifier, soldering the part to the board directly is strongly recommended. try to keep the high frequency big current loop area small to minimize the emi (electromagnetic interfacing). sgm8061 v dd vn vp v ss v out 10f 0.1f 10f 0.1f sgm8061 vn vp v dd v ss (gnd) v out 10f 0.1f figure 2. amplifier with bypass capacitors grounding a ground plane layer is important for high speed circuit design. the length of the current path speed currents in an inductive ground return will create an un wanted voltage noise. broad ground plane areas will reduce the parasitic inductance. input-to-output coupling to minimize capacitive coupling, the input and output signal traces should not be parallel. this helps reduce unwanted positive feedback.
sgm8061/2/3 typical application circuits differential amplifier the circuit shown in figure 3 performs the difference function. if the resistors ratios are equal ( r4 / r3 = r2 / r1 ), then v out = ( vp ? vn ) r 2 / r 1 + vref. vn vp v out sgm8061 vref r1 r2 r3 r4 figure 3. differential amplifier low pass active filter the low pass filter shown in figure 4 has a dc gain of ( - r 2 / r 1 ) and the ?3db corner frequency is 1/2 r 2 c. make sure the filter is within the bandwidth of the am plifier. the large values of feedback resistors can couple with parasitic capacitance and cause undesired effects such as ringing or oscillation in high-speed amplifiers. keep resistors value as low as possible and consistent with output loading consideration. v in v out sgm8061 r1 r2 r3 = r1 // r2 c figure 4. low pass active filter driving video the sgm806x can be used in video applications like in figure 5 . v in sgm8061 r g r f 75 75 cable v out 75 g = 1 + r f / r g figure 5. typical video driving
