10 / 20 page REV. D –10– AD8610/AD8620 Driving Large Capacitive Loads The AD8610 has excellent capacitive load driving capability and can safely drive up to 10 nF when operating with ±5 V supply. Figures 4 and 5 compare the AD8610/AD8620 against the OPA627 in the noninverting gain configuration driving a 10 k Ω resistor and 10,000 pF capacitor placed in parallel on its output, with a square wave input set to a frequency of 200 kHz. The AD8610 has much less ringing than the OPA627 with heavy capacitive loads. TIME – 2 s/DIV VS = 5V CL = 10,000pF RL = 10k Figure 4. OPA627 Driving CL = 10,000 pF TIME – 2 s/DIV VS = 5V CL = 10,000pF RL = 10k Figure 5. AD8610/AD8620 Driving CL = 10,000 pF The AD8610/AD8620 can drive much larger capacitances without any external compensation. Although the AD8610/AD8620 is stable with very large capacitive loads, remember that this capacitive loading will limit the bandwidth of the amplifier. Heavy capacitive loads will also increase the amount of overshoot and ringing at the output. Figures 7 and 8 show the AD8610/AD8620 and the OPA627 in a noninverting gain of +2 driving 2 µF of capacitance load. The ringing on the OPA627 is much larger in magnitude and continues more than 10 times longer than the AD8610. VIN = 50mV 2k 2k –5V +5V 2 F 3 2 7 4 Figure 6. Capacitive Load Drive Test Circuit TIME – 20 s/DIV VS = 5V RL = 10k CL = 2 F Figure 7. OPA627 Capacitive Load Drive, AV = +2 TIME – 20 s/DIV VS = 5V RL = 10k CL = 2 F Figure 8. AD8610/AD8620 Capacitive Load Drive, AV = +2 Slew Rate (Unity Gain Inverting vs. Noninverting) Amplifiers generally have a faster slew rate in an inverting unity gain configuration due to the absence of the differential input capacitance. Figures 9 through 12 show the performance of the AD8610 configured in a gain of –1 compared to the OPA627. The AD8610 slew rate is more symmetrical, and both the positive and negative transitions are much cleaner than in the OPA627. |
