ON MC33178D Low power, low noise operational amplifier Datasheet

MC33178, MC33179
Low Power, Low Noise
Operational Amplifiers
The MC33178/9 series is a family of high quality monolithic
amplifiers employing Bipolar technology with innovative high
performance concepts for quality audio and data signal processing
applications. This device family incorporates the use of high
frequency PNP input transistors to produce amplifiers exhibiting low
input offset voltage, noise and distortion. In addition, the amplifier
provides high output current drive capability while consuming only
420 mA of drain current per amplifier. The NPN output stage used,
exhibits no deadband crossover distortion, large output voltage swing,
excellent phase and gain margins, low open−loop high frequency
output impedance, symmetrical source and sink AC frequency
performance.
The MC33178/9 family offers both dual and quad amplifier
versions in several package options.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. Either or both input voltages should not exceed VCC or VEE.
2. Power dissipation must be considered to ensure maximum junction temperature (TJ) is not exceeded. (See power dissipation performance
characteristic, Figure 2.)

APPLICATION INFORMATION
MC33179 (quad op amp). Shorting more than one amplifier
could easily exceed the junction temperature to the extent of
causing permanent damage.
This unique device uses a boosted output stage to combine
a high output current with a drain current lower than similar
bipolar input op amps. Its 60° phase margin and 15 dB gain
margin ensure stability with up to 1000 pF of load
capacitance (see Figure 24). The ability to drive a minimum
600 W load makes it particularly suitable for telecom
applications. Note that in the sample circuit in Figure 34
both A2 and A3 are driving equivalent loads of
approximately 600 W .
The low input offset voltage and moderately high slew
rate and gain bandwidth product make it attractive for a
variety of other applications. For example, although it is not
single supply (the common mode input range does not
include ground), it is specified at +5.0 V with a typical
common mode rejection of 110 dB. This makes it an
excellent choice for use with digital circuits. The high
common mode rejection, which is stable over temperature,
coupled with a low noise figure and low distortion, is an
ideal op amp for audio circuits.
The output stage of the op amp is current limited and
therefore has a certain amount of protection in the event of
a short circuit. However, because of its high current output,
it is especially important not to allow the device to exceed
the maximum junction temperature, particularly with the
Stability
As usual with most high frequency amplifiers, proper lead
dress, component placement, and PC board layout should be
exercised for optimum frequency performance. For
example, long unshielded input or output leads may result in
unwanted input/output coupling. In order to preserve the
relatively low input capacitance associated with these
amplifiers, resistors connected to the inputs should be
immediately adjacent to the input pin to minimize additional
stray input capacitance. This not only minimizes the input
pole frequency for optimum frequency response, but also
minimizes extraneous “pick up” at this node. Supplying
decoupling with adequate capacitance immediately adjacent
to the supply pin is also important, particularly over
temperature, since many types of decoupling capacitors
exhibit great impedance changes over temperature.
Additional stability problems can be caused by high load
capacitances and/or a high source resistance. Simple
compensation schemes can be used to alleviate these
effects.

MC33178, MC33179
For moderately high capacitive loads (500 pF < CL
< 1500 pF) the addition of a compensation resistor on the
order of 20 W between the output and the feedback loop will
help to decrease miller loop oscillation (see Figure 36). For
high capacitive loads (CL > 1500 pF), a combined
compensation scheme should be used (see Figure 37). Both
the compensation resistor and the compensation capacitor
affect the transient response and can be calculated for
optimum performance. The value of CC can be calculated
using Equation 1. The Equation to calculate RC is as follows:
If a high source of resistance is used (R1 > 1.0 kW), a
compensation capacitor equal to or greater than the input
capacitance of the op amp (10 pF) placed across the
feedback resistor (see Figure 35) can be used to neutralize
that pole and prevent outer loop oscillation. Since the closed
loop transient response will be a function of that
capacitance, it is important to choose the optimum value for
that capacitor. This can be determined by the following
Equation:
CC + (1 ) [R1ńR2])2
CL (ZOńR2)
(1)
RC + ZO
where: ZO is the output impedance of the op amp.
