Dual Wideband, Low Noise, Voltage Feedback Op Amp

General Description

The National LMH6628 is a high speed dual op amp that of-

fers a traditional voltage feedback topology featuring unity

gain stability and slew enhanced circuitry. The LMH6628's

low noise and very low harmonic distortion combine to form

a wide dynamic range op amp that operates from a single (5V

to 12V) or dual (±5V) power supply.

Each of the LMH6628's closely matched channels provides a

300MHz unity gain bandwidth and low input voltage noise

density (2nV/ ). Low 2nd/3rd harmonic distortion (−65/

−74dBc at 10MHz) make the LMH6628 a perfect wide dy-

namic range amplifier for matched I/Q channels.

With its fast and accurate settling (12ns to 0.1%), the

LMH6628 is also an excellent choice for wide dynamic range,

anti-aliasing filters to buffer the inputs of hi resolution analog-

to-digital converters. Combining the LMH6628's two tightly

matched amplifiers in a single package reduces cost and

board space for many composite amplifier applications such

as active filters, differential line drivers/receivers, fast peak

detectors and instrumentation amplifiers.

The LMH6628 is fabricated using National’s VIP10™ compli-

mentary bipolar process.

To reduce design times and assist in board layout, the

LMH6628 is supported by an evaluation board (CLC730036).

Application Section

LOW NOISE DESIGN

Ultimate low noise performance from circuit designs using the

LMH6628 requires the proper selection of external resistors.

By selecting appropriate low valued resistors for RF and RG,

amplifier circuits using the LMH6628 can achieve output

noise that is approximately the equivalent voltage input noise

of 2nV/ multiplied by the desired gain (AV).

DC BIAS CURRENTS AND OFFSET VOLTAGES

Cancellation of the output offset voltage due to input bias cur-

rents is possible with the LMH6628. This is done by making

the resistance seen from the inverting and non-inverting in-

puts equal. Once done, the residual output offset voltage will

be the input offset voltage (VOS) multiplied by the desired gain

(AV). National Application Note OA-7 offers several solutions

to further reduce the output offset.

OUTPUT AND SUPPLY CONSIDERATIONS

With ±5V supplies, the LMH6628 is capable of a typical output

swing of ±3.8V under a no-load condition. Additional output

swing is possible with slightly higher supply voltages. For

loads of less than 50Ω, the output swing will be limited by the

LMH6628's output current capability, typically 85mA.

Output settling time when driving capacitive loads can be im-

proved by the use of a series output resistor. See the plot

labeled "RS vs. CL" in the Typical Performance section.

LAYOUT

Proper power supply bypassing is critical to insure good high

frequency performance and low noise. De-coupling capaci-

tors of 0.1μF should be placed as close as possible to the

power supply pins. The use of surface mounted capacitors is

recommended due to their low series inductance.

A good high frequency layout will keep power supply and

ground traces away from the inverting input and output pins.

Parasitic capacitance from these nodes to ground causes fre-

quency response peaking and possible circuit oscillation. See

OA-15 for more information. National suggests the 730036

(SOIC) dual op amp evaluation board as a guide for high fre-

quency layout and as an aid in device evaluation.

ANALOG DELAY CIRCUIT (ALL-PASS NETWORK)

The circuit in Figure 1 implements an all-pass network using

the LMH6628. A wide bandwidth buffer (LM7121) drives the

circuit and provides a high input impedance for the source. As

shown in Figure 2, the circuit provides a 13.1ns delay (with R

= 40.2Ω, C = 47pF). RF and RG should be of equal and low

value for parasitic insensitive operation.

20151501

FIGURE 1.

20151502

FIGURE 2. Delay Circuit Response to 0.5V Pulse

The circuit gain is +1 and the delay is determined by the fol-

lowing equations.

(1)

(2)

where Td is the delay of the op amp at AV = +1.

The LMH6628QML provides a typical delay of 2.8ns at its

−3dB point.

FULL DUPLEX DIGITAL OR ANALOG TRANSMISSION

Simultaneous transmission and reception of analog or digital

signals over a single coaxial cable or twisted-pair line can re-

duce cabling requirements. The LMH6628's wide bandwidth

and high common-mode rejection in a differential amplifier

configuration allows full duplex transmission of video, tele-

phone, control and audio signals.

In the circuit shown in Figure 3, one of the LMH6628's amps

is used as a "driver" and the other as a difference "receiver"

amplifier. The output impedance of the "driver" is essentially

www.national.com 10

LMH6628QML

zero. The two R's are chosen to match the characteristic

impedance of the transmission line. The "driver" op amp gain

can be selected for unity or greater.

Receiver amplifier A2 (B2) is connected across R and forms

differential amplifier for the signals transmitted by driver A2

(B2). If RF equals RG, receiver A2 (B1) will then reject the sig-

nals from driver A1 (B1) and pass the signals from driver B1

(A1).

20151503

FIGURE 3.

The output of the receiver amplifier will be:

(3)

Care must be given to layout and component placement to

maintain a high frequency common-mode rejection. The plot

of Figure 4 shows the simultaneous reception of signals trans-

mitted at 1MHz and 10MHz.

20151531

FIGURE 4.

POSITIVE PEAK DETECTOR

The LMH6628's dual amplifiers can be used to implement a

unity-gain peak detector circuit as shown in Figure 5.

20151505

FIGURE 5.

The acquisition speed of this circuit is limited by the dynamic

resistance of the diode when charging Chold. A plot of the

circuit's performance is shown in Figure 6 with a 1MHz sinu-

soidal input.

20151537

FIGURE 6.

A current source, built around Q1, provides the necessary

bias current for the second amplifier and prevents saturation

when power is applied. The resistor, R, closes the loop while

diode D2 prevents negative saturation when VIN is less than

VC. A MOS-type switch (not shown) can be used to reset the

capacitor's voltage.

The maximum speed of detection is limited by the delay of the

op amps and the diodes. The use of Schottky diodes will pro-

vide faster response.

ADJUSTABLE OR BANDPASS EQUALIZER

A "boost" equalizer can be made with the LMH6628 by sum-

ming a bandpass response with the input signal, as shown in

Figure 7.

LMH6628QML

20151506

FIGURE 7.

The overall transfer function is shown in Eq. 5.

(4)

To build a boost circuit, use the design equations Eq. 6 and

Eq. 7.

(5)

(6)

Select R2 and C using Eq. 6. Use reasonable values for high

frequency circuits - R2 between 10Ω and 5kΩ, C between

10pF and 2000pF. Use Eq. 7 to determine the parallel com-

bination of Ra and Rb. Select Ra and Rb by either the 10Ω to

5kΩ criteria or by other requirements based on the impedance

Vin is capable of driving. Finish the design by determining the

value of K from Eq. 8.

(7)

Figure 8 shows an example of the response of the circuit of

Figure 9, where fo is 2.3MHz. The component values are as

follows: Ra=2.1kΩ, Rb = 68.5Ω, R2 = 4.22kΩ, R = 500Ω, KR

= 50Ω, C = 120pF.
