Driving Capacitive Load
The ability to maintain shutoff is shown on the curve
Shutdown Supply Current vs Temperature in the Typical
Performance Characteristics section. At very high
elevated temperatures it is important to hold the shut-
down pin close to the negative supply to keep the supply
current from increasing.
Murphy Circuits
There are several precautions the user should take when
using the LT1190 in order to realize its full capability.
Although the LT1190 can drive a 50pF load, isolating the
capacitance with 10
can be helpful. Precautions prima-
rily have to do with driving large capacitive loads.
Other precautions include:
1. Use a ground plane (see Design Note 50, High Fre-
quency Amplifier Evaluation Board).
2. Do not use high source impedances. The input
capacitance of 2pF and RS = 10k for instance, will give
an 8MHz – 3dB bandwidth.
3. PC board socket may reduce stability.
4. A feedback resistor of 1k or lower reduces the effects of
stray capacitance at the inverting input. (For instance,
closed-loop gain of 2 can use RFB = 300 and RG =
300
.)
