DESCRIPTION
The MC3403 is a low-cost, quad operational am-
plifier with true differential i nputs. The devic e has
electrical characteristics similar to the popular
UA741. However the MC3403, has several dis-
tinct adv antages over standa rd operat iona l ampli -
fiers types in single supply applications. The quad
amplifi er can operate at supply voltage as low as 3
Volts or as high as 36 volts with quiescent currents
about one third of those associated with the
UA741 (on a per amplifier basis). The com-
mon-m ode inpu t range includes the negat ive sup-
ply, thereby eliminating the necessity for external
biasing compo nent s in many applications.

CIRCUIT DESC RIPTION
The MC3403 is made using four internally com-
pensated, two-stage operational amplifiers. The
first stage of each consists of differential input de-
vices Q24 and Q22 with input buffer transistors
Q25 and Q2 1 a nd the differential to single ended
converter Q3 and Q4. The first stage performs not
only the first stage gain function but also performs
the level shifting and transonductance reduction
functions. By reducing the transconductance a
smaller compensation capacitor (only 8pF) can be
employed, thus saving chip area.
The transconductance reduction is accomplished
by splitting the collectors of Q24 and Q22. Another
feature of this input stage is that the input com-
mon-m ode range can include the negative supply
fo grou nd, in single supply ope ra tio n, witho ut sat-
uration either the input devices or the differential
to single-ended c onverter.
The second stage consists of a standard current
source load amplifier stage. The output stage is
unique because it allows the output to swing to
ground in single supply operation and yet does not
exh ibit any crossov er disto rtion in split supply op-
era tio ns. Thi s is possibl e because class AB oper-
ation is utilized.
Each amplifier is biased from an internal voltage
regulator whi ch has a low temperature coef ficient
thus giving each amplifier good temperature char-
acteristi cs as well as excel lent power s upply reje c-
tion.
