Printed-Circuit Layout

OUTMAX

The EL2227 are well behaved, and easy to apply in most

applications. However, a few simple techniques will help

assure rapid, high quality results. As with any high-frequency

device, good PCB layout is necessary for optimum

performance. Ground-plane construction is highly

recommended, as is good power supply bypassing. A 0.1µF

ceramic capacitor is recommended for bypassing both

supplies. Lead lengths should be as short as possible, and

bypass capacitors should be as close to the device pins as

possible. For good AC performance, parasitic capacitances

should be kept to a minimum at both inputs and at the

output. Resistor values should be kept under 5kΩ because

of the RC time constants associated with the parasitic

capacitance. Metal-film and carbon resistors are both

acceptable, use of wire-wound resistors is not

1.4V, and R = 150Ω, giving the results seen in Table 1.

Single-Supply Operation

The EL2227 have been designed to have a wide input and

output voltage range. This design also makes the EL2227 an

excellent choice for single-supply operation. Using a single

positive supply, the lower input voltage range is within

200mV of ground (R = 500Ω), and the lower output voltage

recommended because of their parasitic inductance.

Similarly, capacitors should be low-inductance for best

performance.

range is within 875mV of ground. Upper input voltage range

reaches 3.6V, and output voltage range reaches 3.8V with a

5V supply and R = 500Ω. This results in a 2.625V output

swing on a single 5V supply. This wide output voltage range

also allows single-supply operation with a supply voltage as

high as 28V.

Gain-Bandwidth Product and the -3dB Bandwidth

The EL2227 have a gain-bandwidth product of 137MHz

while using only 5mA of supply current per amplifier. For

gains greater than 2, their closed-loop -3dB bandwidth is

approximately equal to the gain-bandwidth product divided

by the noise gain of the circuit. For gains less than 2, higher-

order poles in the amplifiers' transfer function contribute to

even higher closed loop bandwidths. For example, the

EL2227 have a -3dB bandwidth of 115MHz at a gain of +2,

dropping to 28MHz at a gain of +5. It is important to note that

the EL2227 have been designed so that this “extra”

bandwidth in low-gain applications does not come at the

expense of stability. As seen in the typical performance

curves, the EL2227 in a gain of +2 only exhibit 0.5dB of

peaking with a 1000Ω load.

Output Drive Capability

The EL2227 have been designed to drive low impedance

loads. They can easily drive 6V into a 500Ω load. This

high output drive capability makes the EL2227 an ideal

choice for RF, IF and video applications.
