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

variation of the integrated circuit sensitivity with either digital

and/or analog programming signals. For example, at an I

of 100 A, a 1mV change at the input will change the output

from 0 to 100 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).
