1.0 Mounting
(Continued)
The table shown in Figure 3 summarizes the rise in die tem-
perature of the LM62 without any loading, and the thermal
resistance for different conditions.
2.0 Capacitive Loads
The LM62 handles capacitive loading well. Without any spe-
cial precautions, the LM62 can drive any capacitive load as
shown in Figure 4 Over the specified temperature range the
LM62 has a maximum output impedance of 4.7 k
. 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 sup-
ply 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 4.7 k
maximum
output impedance will form a 34 Hz lowpass filter. Since the
thermal time constant of the LM62 is much slower than the
30 ms time constant formed by the RC, the overall response
time of the LM62 will not be significantly affected. For much
larger capacitors this additional time lag will increase the
overall response time of the LM62.
