LPC660

Low Power CMOS Quad Operational Amplifier

General Description

The LPC660 CMOS Quad operational amplifier is ideal for

operation from a single supply. It features a wide range of

operating voltages from +5V to +15V and features rail-to-rail

output swing in addition to an input common-mode range

that includes ground. Performance limitations that have

plagued CMOS amplifiers in the past are not a problem with

this design. Input V

, drift, and broadband noise as well as

voltage gain (into 100 kΩand5kΩ) are all equal to or better

than widely accepted bipolar equivalents, while the power

supply requirement is typically less than 1 mW.

This chip is built with National’s advanced Double-Poly

Silicon-Gate CMOS process.

See the LPC662 datasheet for a Dual CMOS operational

amplifier and LPC661 datasheet for a single CMOS opera-

tional amplifier with these same features.

Application Hints

AMPLIFIER TOPOLOGY

The topology chosen for the LPC660 is unconventional

(compared to general-purpose op amps) in that the tradi-

tional unity-gain buffer output stage is not used; instead, the

output is taken directly from the output of the integrator, to

allow rail-to-rail output swing. Since the buffer traditionally

delivers the power to the load, while maintaining high op

amp gain and stability, and must withstand shorts to either

rail, these tasks now fall to the integrator.

As a result of these demands, the integrator is a compound

affair with an embedded gain stage that is doubly fed forward

(via C

and C

) by a dedicated unity-gain compensation

driver. In addition, the output portion of the integrator is a

push-pull configuration for delivering heavy loads. While

sinking current the whole amplifier path consists of three

gain stages with one stage fed forward, whereas while

sourcing the path contains four gain stages with two fed

forward.

The large signal voltage gain while sourcing is comparable

to traditional bipolar op amps, for load resistance of at least

5kΩ. The gain while sinking is higher than most CMOS op

amps, due to the additional gain stage; however, when driv-

ing load resistance of 5 kΩor less, the gain will be reduced

as indicated in the Electrical Characteristics. The op amp

can drive load resistance as low as 500Ωwithout instability.

COMPENSATING INPUT CAPACITANCE

Refer to the LMC660 or LMC662 datasheets to determine

whether or not a feedback capacitor will be necessary for

compensation and what the value of that capacitor would be.

CAPACITIVE LOAD TOLERANCE

Like many other op amps, the LPC660 may oscillate when

its applied load appears capacitive. The threshold of oscilla-

tion varies both with load and circuit gain. The configuration

most sensitive to oscillation is a unity-gain follower. See the

Typical Performance Characteristics.

The load capacitance interacts with the op amp’s output

resistance to create an additional pole. If this pole frequency

is sufficiently low, it will degrade the op amp’s phase margin

so that the amplifier is no longer stable at low gains. The

addition of a small resistor (50Ωto 100Ω) in series with the

op amp’s output, and a capacitor (5 pF to 10 pF) from

inverting input to output pins, returns the phase margin to a

safe value without interfering with lower-frequency circuit

operation. Thus, larger values of capacitance can be toler-

ated without oscillation. Note that in all cases, the output will

ring heavily when the load capacitance is near the threshold

for oscillation.

Capacitive load driving capability is enhanced by using a pull

up resistor to V

(Figure 3). Typically a pull up resistor

conducting 50 µA or more will significantly improve capaci-

tive load responses. The value of the pull up resistor must be

determined based on the current sinking capability of the

amplifier with respect to the desired output swing. Open loop

gain of the amplifier can also be affected by the pull up

resistor (see Electrical Characteristics).

PRINTED-CIRCUIT-BOARD LAYOUT

FOR HIGH-IMPEDANCE WORK

It is generally recognized that any circuit which must operate

with less than 1000 pA of leakage current requires special

layout of the PC board. When one wishes to take advantage

of the ultra-low bias current of the LPC660, typically less

than 0.04 pA, it is essential to have an excellent layout.

Fortunately, the techniques for obtaining low leakages are

quite simple. First, the user must not ignore the surface

leakage of the PC board, even though it may sometimes

appear acceptably low, because under conditions of high

humidity or dust or contamination, the surface leakage will

be appreciable.

To minimize the effect of any surface leakage, lay out a ring

of foil completely surrounding the LPC660’s inputs and the

terminals of capacitors, diodes, conductors, resistors, relay

terminals, etc. connected to the op-amp’s inputs. See Figure

4. To have a significant effect, guard rings should be placed

on both the top and bottom of the PC board. This PC foil

must then be connected to a voltage which is at the same

voltage as the amplifier inputs, since no leakage current can

flow between two points at the same potential. For example,

a PC board trace-to-pad resistance of 10

ohms, which is

normally considered a very large resistance, could leak 5 pA

if the trace were a 5V bus adjacent to the pad of an input.

This would cause a 100 times degradation from the

LPC660’s actual performance. However, if a guard ring is

held within 5 mV of the inputs, then even a resistance of

ohms would cause only 0.05 pA of leakage current, or

perhaps a minor (2:1) degradation of the amplifier’s perfor-

mance. See Figure 5a,Figure 5b,Figure 5c for typical

connections of guard rings for standard op-amp configura-

tions. If both inputs are active and at high impedance, the

guard can be tied to ground and still provide some protec-

tion; see Figure 5d.

LPC660

www.national.com 10

Application Hints (Continued)

The designer should be aware that when it is inappropriate

to lay out a PC board for the sake of just a few circuits, there

is another technique which is even better than a guard ring

on a PC board: Don’t insert the amplifier’s input pin into the

board at all, but bend it up in the air and use only air as an

insulator. Air is an excellent insulator. In this case you may

have to forego some of the advantages of PC board con-

struction, but the advantages are sometimes well worth the

effort of using point-to-point up-in-the-air wiring.

BIAS CURRENT TESTING

The test method of Figure 7 is appropriate for bench-testing

bias current with reasonable accuracy. To understand its

operation, first close switch S2 momentarily. When S2 is

opened, then

A suitable capacitor for C2 would be a 5 pF or 10 pF silver

mica, NPO ceramic, or air-dielectric. When determining the

magnitude of I

−

, the leakage of the capacitor and socket

must be taken into account. Switch S2 should be left shorted

most of the time, or else the dielectric absorption of the

capacitor C2 could cause errors.

Similarly, if S1 is shorted momentarily (while leaving S2

shorted)
