Figure 3. Capacitive Load with RNULL
VIN VIN 100mV/div 100mV/div VOUT VOUT 100mV/div 100mV/div Time 5μs/div Time 5μs/div
Figure 4. Test Result Without RNULL Figure 5. Test Result with RNULL 330Ω
Reducing capacitive load ringing and overshoot, the RC snubber circuit also can be used, shown in Figure 6, it does allow the amplifier to drive larger values of capacitance while maintaining a minimum of overshoot and ringing. Figure 7 shows AS2333 test result for capacitive load 470pF with snubber circuit. VIN 100mV/div VOUT 100mV/div Time 5μs/div
