Figure 15
shows the gain vs frequency performance at various attenuation settings using a 3 pF external
feedback capacitor connected across the I

X and R
FB
X terminals. In order to maintain good analog
performance, power-supply bypassing of 0.01
μ
μ
F, is recommended. Under these conditions,
clean power supply with low ripple voltage capability should be used. Switching power supplies is usually not
suitable for this application due to the higher ripple voltage and P
frequency-dependent characteristics. It is
best to derive the DAC8812 5-V supply from the system analog supply voltages (do not use the digital 5-V
supply); see
