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 800Ω. In an ex-
tremely 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
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
FIGURE 5. LM60 with Filter for Noisy Environment
1 μF output capacitor with the 800Ω output impedance 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 capacitors this
additional time lag will increase the overall response time of
the LM60.
