2.0 Capacitive Loads
The LM60 handles capacitive loading well. Without any spe-
cial precautions, the LM60 can drive any capacitive load as
shown in Figure 4 Over the specified temperature range the
LM60 has a maximum output impedance of 800
. In an
extremely noisy environment it may be necessary to add
some filtering to minimize noise pickup. It is recommended
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 environment
it may be necessary to add a capacitor from the output to
ground. A 1 μF output capacitor with the 800
output imped-
ance will form a 199 Hz lowpass filter. Since the thermal time
constant of the LM60 is much slower than the 6.3 ms time
constant formed by the RC, the overall response time of the
LM60 will not be significantly affected. For much larger ca-
pacitors this additional time lag will increase the overall
response time of the LM60.
