•
•
Video switchers/routers
Video line drivers
The flat gain response to 120 MHz, 450 MHz small
signal bandwidth and 1500 V/µs slew rate make the
device an excellent solution for video applications such
as driving video signals down significant cable lengths.
Twisted pair driver/receiver
Active filters
Other applications which may take advantage of the
ZL40122 superior dynamic performance features
include low cost high order active filters and twisted pair
driver/receivers.
Description
The ZL40122 is a high speed, quad, current feedback
operational amplifier offering high performance at a
low cost. The device has a very high output current
drive capability of 65 mA while requiring only 5.2 mA of
static supply current. This feature makes the ZL40122

Application Notes
Current Feedback Op Amps
Current feedback op amps offer several advantages over voltage feedback amplifiers:
•
•
•
AC bandwidth not dependent on closed loop gain
High Slew Rate
Fast settling time
The architecture of the current feedback opamp consists of a high impedance non-inverting input and a low
impedance inverting input which is always feedback connected. The error current is amplified by a transimpedance
amplifier which can be considered to have gain
Zo
Z( f ) =
f
1+ j
fo
where Zo is the DC gain.
It can be shown that the closed loop non-inverting gain is given by
Vout
Vin
Av
=
fRf
1+ j
foZo
where Av is the DC closed loop gain, Rf is the feedback resistor. The closed loop bandwidth is therefore given by
foZo GBOL
BWCL =
=
Rf
Rf
and for low values of closed loop gain Av depends only on the feedback resistor Rf and not the closed loop gain.
Increasing the value of Rf
•
•
•
•
•
Increases closed loop stability
Decreases loop gain
Decreases bandwidth
Reduces gain peaking
Reduces overshoot
Using a resistor value of Rf=510 Ω for Av=+2 V/V gives good stability and bandwidth. However since requirements
for stability and bandwidth vary it may be worth experimentation to find the optimal Rf for a given application.
Layout Considerations
Correct high frequency operation requires a considered PCB layout as stray capacitances have a strong influence
over high frequency operation for this de0ice. The Zarlink evaluation board serves as a good example layout that
should be copied. The following guidelines should be followed:
•
•
Include 6.8 uF tantalum and 0.1 uF ceramic capacitors on both positive and negative supplies
Remove the ground plane under and around the part, especially near the input and output pins to reduce
parasitic capacitances
•
Minimize all trace lengths to reduce series inductance

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate
conditions for which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed
specifications and the test conditions, see the Electrical Characteristics.
