2.0 Capacitive Loads
The SM73710 handles capacitive loading well. Without any
special precautions, the SM73710 can drive any capacitive
load as shown in Figure 4. Over the specified temperature
range the SM73710 has a maximum output impedance of
800Ω. In an extremely noisy environment it may be necessary
to add some filtering to minimize noise pickup. It is recom-
mended that 0.1 μF be added from +V _S to GND to bypass the
power supply voltage, as shown in Figure 5. In a noisy envi-
ronment it may be necessary to add a capacitor from the
output to ground. A 1 μF output capacitor with the 800Ω output
impedance will form a 199 Hz lowpass filter. Since the thermal
time constant of the SM73710 is much slower than the 6.3 ms
time constant formed by the RC, the overall response time of
the SM73710 will not be significantly affected. For much larg-
er capacitors this additional time lag will increase the overall
response time of the SM73710.
