970 a, 10mhz, rail-to-rail i/o sgm721/2/3/4 cmos operational amplifiers 9 sg micro corp www.sg-micro.com application notes driving capacitive loads the sgm721/2/3/4 can directly drive 4700pf in unity-gain without oscillation. the unity-gain follower (buffer) is the most sensitive configuration to capacitive loading. direct capacitive loading reduces the phase margin of amplifiers and this results in ringing or even oscillation. applications that require greater capacitive driving capability should use an isolation resistor between the output and the capacitive load like the circuit in figure 1. the isolation resistor r iso and the load capacitor c l form a zero to increase stability. the bigger the r iso resistor value, the more stable v out will be. note that this method results in a loss of gain accuracy because r iso forms a voltage divider with the r load . v in v out sgm721 c l r iso figure 1. indirectly driving heavy capacitive load an improved circuit is shown in figure 2. it provides dc accuracy as well as ac stability. r f provides the dc accuracy by connecting the inverting signal with the output. c f and r iso serve to counteract the loss of phase margin by feeding the high frequency component of the output signal back to the amplifier?s inverting input, thereby preserving phase margin in the overall feedback loop. v in v out sgm721 c l r iso r l r f c f figure 2. indirectly driving heavy capacitive load with dc accuracy for non-buffer configuration, there are two other ways to increase the phase margin: (a) by increasing the amplifier?s gain or (b) by placing a capacitor in parallel with the feedback resistor to counteract the parasitic capacitance associated with inverting node. power-supply bypassing and layout the sgm721/2/3/4 operate from either a single +2.5v to +5.5v supply or dual 1.25v to 2.75v supplies. for single-supply operation, bypass the power supply +v s with a 0.1f ceramic capacitor which should be placed close to the +v s pin. for dual-supply operation, both the +v s and the -v s supplies should be bypassed to ground with separate 0.1f ceramic capacitors. 2.2f 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 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). sgm721 v dd vn vp v ss v out 10f 0.1f 10f 0.1f sgm721 vn vp v dd v ss (gnd) v out 10f 0.1f figure 3. amplifier with bypass capacitors grounding a ground plane layer is important for sgm72x circuit design. the length of the current path speed currents in an inductive ground return will create an unwanted 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.
