Features
Transconductance Amplifier (OTA)
• Low Initial Input Offset Voltage: 500µV (Max) (CA3280A)
The CA3280 and CA3280A types consist of two variable
operational amplifiers that are designed to substantially reduce
the initial input offset voltage and the offset voltage variation
with respect to changes in programming current. This design
• Low Offset Voltage Change vs IABC: <500µV (Typ)
for All Types
• Low Offset Voltage Drift: 5µV/oC (Max) (CA3280A)
results in reduced “AGC thump,” an objectionable characteristic
• Excellent Matching of the Two Amplifiers for All
of many AGC systems. Interdigitation, or crosscoupling, of
critical portions of the circuit reduces the amplifier dependence
upon thermal and processing variables.
mThe CA3280 has all the generic characteristics of an
operational voltage amplifier except that the forward transfer
ocharacteristics is best described by transconductance rather
.cthan voltage gain, and the output is current, not voltage. The
magnitude of the output current is equal to the product of
transconductance and the input voltage. This type of
Uoperational transconductance amplifier was first introduced in
1969, and it has since gained wide acceptance as a gateable,
t4gain controlled building block for instrumentation and audio
applications, such as linearization of transducer outputs,
estandardization of widely changing signals for data processing,
multiplexing, instrumentation amplifiers operating from the
enanopower range to high current and high speed comparators.
hFor additional application information on this device and on
OTAs in general, please refer to Application Notes: AN6818,
SAN6668, and AN6077.
