The HA5025 is a wide bandwidth high slew rate quad

ampliﬁer optimized for video applications and gains between

1 and 10. It is a current feedback ampliﬁer and thus yields

less bandwidth degradation at high closed loop gains than

voltage feedback ampliﬁers.

The low differential gain and phase, 0.1dB gain ﬂatness, and

ability to drive two back terminated 75Ω cables, make this

ampliﬁer ideal for demanding video applications.

The current feedback design allows the user to take

advantage of the ampliﬁer’s bandwidth dependency on the

feedback resistor.

NOTES:

o

1. Maximum power dissipation, including output load, must be designed to maintain junction temperature below 175 C for die, and below 150 C

for plastic packages. See Application Information section for safe operating area information.

2. θ is measured with the component mounted on an evaluation PC board in free air.

JA

3. The non-inverting input of unused amplifiers must be connected to GND.

4. Output is protected for short circuits to ground. Brief short circuits to ground will not degrade reliability, however, continuous (100% duty cycle)

output current should not exceed 15mA for maximum reliability.

Application Information

Optimum Feedback Resistor

The plots of inverting and non-inverting frequency response,

see Figure 8 and Figure 9 in the typical performance section,

illustrate the performance of the HA5025 in various closed

loop gain configurations. Although the bandwidth dependency

on closed loop gain isn’t as severe as that of a voltage

feedback amplifier, there can be an appreciable decrease in

bandwidth at higher gains. This decrease may be minimized

by taking advantage of the current feedback amplifier’s unique

Driving Capacitive Loads

Capacitive loads will degrade the ampliﬁer’s phase margin

resulting in frequency response peaking and possible

oscillations. In most cases the oscillation can be avoided by

placing an isolation resistor (R) in series with the output as

shown in Figure 6.

frequency response. Thus, the amplifier’s bandwidth is

inversely proportional to R . The HA5025 design is optimized

for a 1000Ω R at a gain of +1. Decreasing R in a unity gain

application decreases stability, resulting in excessive peaking

and overshoot. At higher gains the amplifier is more stable, so

The selection criteria for the isolation resistor is highly

dependent on the load, but 27Ω has been determined to be

a good starting value.

R can be decreased in a trade-off of stability for bandwidth.

PC Board Layout

The frequency response of this ampliﬁer depends greatly on

the amount of care taken in designing the PC board. The

use of low inductance components such as chip resistors

and chip capacitors is strongly recommended. If leaded

components are used the leads must be kept short

especially for the power supply decoupling components and

those components connected to the inverting input.

Attention must be given to decoupling the power supplies. A

large value (10µF) tantalum or electrolytic capacitor in

parallel with a small value (0.1µF) chip capacitor works well

in most cases.

SUPPLY VOLTAGE (±V)

A ground plane is strongly recommended to control noise.

Care must also be taken to minimize the capacitance to

ground seen by the amplifier’s inverting input (-IN). The larger

this capacitance, the worse the gain peaking, resulting in

pulse overshoot and possible instability. It is recommended

that the ground plane be removed under traces connected to
