GENERAL DESCRIPTIONThe OP292/OP492 are low cost, general purpose dual and quad
operational amplifiers designed for single-supply applications
and are ideal for 5 olt systems.
Fabricated on Analog Devices’ CBCMOS process, the OP292/
OP492 series has a PNP input stage that allows the input voltage
range to include ground. A BiCMOS output stage enables the
output to swing to ground while sinking current.
The OP292/OP492 series is unity-gain stable and features an
outstanding combination of speed and performance for single-
or dual-supply operation. The OP292/OP492 provide high slew
rate, high bandwidth, with open-loop gain exceeding 40,000
and offset voltage under 800 � (OP292) and 1 mV (OP492).
With these combinations of features and low supply current, the
OP292/OP492 series is an excellent choice for battery-operated
applications.
The OP292/OP492 series performance is specified for single- or
dual-supply voltage operation over the extended industrial tem-
perature range (–40∞C to +125∞C).
Package options for the OP292 and OP492 include plastic DIP,
SO-8 (OP292) and SO-14.

APPLICATION INFORMATION
Phase ReversalThe OP492 has built-in protection against phase reversal when
the input voltage goes to either supply rail. In fact, it is safe for
the input to exceed either supply rail by up to 0.6 V with no risk
of phase reversal. However, the input should not go beyond the
positive supply rail by more than 0.9 V, otherwise the output
will reverse phase. If this condition can occur, the problem can
be fixed by adding a 5 k� current limiting resistor in series with
the input pin. With this addition, the input can go to more than
5 V beyond the positive rail without phase reversal.
An input voltage that is as much as 5 V below the negative rail
will not result in phase reversal.
Figure 1.Output Phase Reverse If Input Exceeds the Posi-
tive Supply (V+) by More Than 0.9V
Figure 2.No Negative Rail Phase Reversal, Even with Input
Power Supply ConsiderationsThe OP292/OP492 are designed to operate equally well at single 5V
or �15 V supplies. The lowest supply voltage recommended is 4.5V.
It is a good design practice to bypass the supply pins with a 0.1 mF
ceramic capacitor. It helps improve filtering of high frequency noise.
For dual supply operation, the negative supply (V–) must be applied
at the same time, or before V�. If V� is applied before V–, or in
the case of a loss of V– supply, while either input is connected to
ground or other low impedance source, excessive input current
may result. Potentially damaging levels of input current can de-
stroy the amplifier. If this condition can exist, simply add a l k�
or larger resistor in series with the input to eliminate the problem.
TYPICAL APPLICATIONS
Direct Access Arrangement for Telephone Line InterfaceFigure 3 shows a 5 V- only transmit/receive telephone line inter-
face for a modem circuit. It allows full duplex transmission of modem
signals on a transformer-coupled 600 V line in a differential man-
ner. The transmit section gain can be set for the specific modem
device output. Similarly the receive amplifier gain can be appro-
priately selected based on the modem device input requirements.
The circuit operates on a single 5V supply. The standard value
resistors allow the use of a SIP-packaged resistor array; coupled
with a quad op amp in a single package, this offers a compact,
low part-count solution.
