Again, the component leads To drive capacitive loads greater than 100 pF, the load should should be kept very short.

When using a 15 pF feedback capacitor, this circuit can drive 400 pF with less than 20% overshoot, as illustrated in Fig- ures 21b and 21c. Increasing capacitor C to 47 pF also in- F creases the capacitance drive capability to 1000 pF, at the expense of a 10:1 reduction in bandwidth compared with the simple unity gain inverter circuit of Figure 20a. Unity gain voltage followers (buffers) are more sensitive to capacitive loads than are inverting amplifiers because there is no attenuation of the feedback signal. The AD843 can drive 10 pF to 20 pF when connected in the basic unity gain buffer circuit of Figure 22a. The 1 kW resistor in series with the AD843’s noninverting input serves two functions: first, together with the amplifier’s input capacitance, it forms a low-pass filter which slows down the actual signal seen by the AD843. This helps reduce ringing on Figure 24.Recommended Power Supply Bypassing for the amplifier’s output voltage. The resistor’s second function is the AD843 (DIP Pinout) to limit the current into the amplifier when the differential input voltage exceeds the total supply voltage. USING A HEAT SINK The AD843 will deliver a much “cleaner” pulse response when The AD843 consumes less quiescent power than most precision connected in the somewhat more elaborate follower circuit of high speed amplifiers and is specified to operate without using a Figure 23a. Note the reduced overshoot in Figure 23b and 23c heat sink.

Even with these low resistance sink, such as the Mouser Electronics #33HS008 is recommended. values, the resultant RC time constant formed between them and stray circuit capacitances is large enough to cause peaking in the amplifier’s response. Adding a small capacitor, C , as F shown in Figures 20a to 23a will reduce this peaking and flatten the overall frequency response. C will normally be less than F 10pF in value. The AD843 can drive resistive loads over the range of 500 W to ¥ with no change in dynamic response. While a 499 W load was used in the circuits of Figures 20-23, the performance of these circuits will be essentially the same even if this load is removed or changed to some other value, such as 2 kW . To obtain the “cleanest” possible transient response when driv- ing heavy capacitive loads, be sure to connect bypass capacitors directly between the power supply pins of the AD843 and ground as outlined in “grounding and bypassing.” Offset Null Configuration (DIP Pinout) –8– REV.
