Application Information
For additional application information, refer to
Application Note AN6048, “Some Applications of a
Programmable Power/Switch Amplifier IC” and AN6077
“An IC Operational Transconductance Amplifier (OTA)
with Power Capability”.
Design Considerations
The selection of the optimum amplifier bias current (I
ABC
)
depends on:
1. The Desired Sensitivity - The higher the I
ABC
, the higher
the sensitivity, i.e., a greater drive current capability at the
output for a specific voltage change at the input.
2. Required Input Resistance - The lower the I
ABC
, the high-
er the input resistance.
If the desired sensitivity and required input resistance are
not known and are to be experimentally determined, or the
anticipated equipment design is sufficiently flexible to
tolerate a wide range of these parameters, it is
recommended that the equipment designer begin his
calculations with an I
ABC
of 100
μ
A, since the CA3094 is
characterized at this value of amplifier bias current.
The CA3094 is extremely versatile and can be used in a
wide variety of applications.
