30MHz, High Output Current Operational
Transconductance Amplifier (OTA)
The CA3094 is a differential input power control
switch/amplifier with auxiliary circuit features for ease of
programmability. For example, an error or unbalance signal
can be amplified by the CA3094 to provide an on-off signal or
proportional control output signal up to 100mA. This signal is
sufficient to directly drive high current thyristors, relays, DC
loads, or power transistors. The CA3094 has the generic
characteristics of the CA3080 operational amplifier directly
coupled to an integral Darlington power transistor capable of
sinking or driving currents up to 100mA.
The gain of the differential input stage is proportional to the
amplifier bias current (I
ABC
), permitting programmable
variation of the integrated circuit sensitivity with either digital
and/or analog programming signals. For example, at an I
ABC
of 100
μ
A, a 1mV change at the input will change the output
from 0 to 100
μ
A (typical).
The CA3094 is intended for operation up to 24V and is
especially useful for timing circuits, in automotive equipment,
and in other applications where operation up to 24V is a
primary design requirement (see Figures 28, 29 and 30 in
Typical Applications text). The CA3094A and CA3094B are
like the CA3094 but are intended for operation up to 36V and
44V, respectively (single or dual supply).
