LT1228  
100MHz Current Feedback  
Amplifier with DC Gain Control  
U
FEATURES  
DESCRIPTIO  
The LT®1228 makes it easy to electronically control the  
gain of signals from DC to video frequencies. The LT1228  
implements gain control with a transconductance ampli-  
fier (voltage to current) whose gain is proportional to an  
externally controlled current. A resistor is typically used to  
convert the output current to a voltage, which is then  
amplified with a current feedback amplifier. The LT1228  
combines both amplifiers into an 8-pin package, and  
operates on any supply voltage from 4V (± 2V) to 30V  
(±15V). A complete differential input, gain controlled  
amplifier can be implemented with the LT1228 and just a  
few resistors.

Very Fast Transconductance Amplifier  
Bandwidth: 75MHz  
gm = 10 × ISET  
Low THD: 0.2% at 30mVRMS Input  
Wide ISET Range: 1µA to 1mA  
■
Very Fast Current Feedback Amplifier  
Bandwidth: 100MHz  
Slew Rate: 1000V/µs  
Output Drive Current: 30mA  
Differential Gain: 0.04%  
Differential Phase: 0.1°  
High Input Impedance: 25MΩ, 6pF  
■
Wide Supply Range: ±2V to ±15V  
The LT1228 transconductance amplifier has a high imped-  
ancedifferentialinputandacurrentsourceoutputwithwide  
output voltage compliance. The transconductance, gm, is  
setbythecurrentthatflowsintoPin5, ISET. Thesmallsignal  
gm isequaltotentimesthevalueofISETandthisrelationship  
holds over several decades of set current. The voltage at Pin  
5 is two diode drops above the negative supply, Pin 4.

APPLICATIO S  
■
Video DC Restore (Clamp) Circuits  
■
The LT1228 current feedback amplifier has very high input  
impedance and therefore it is an excellent buffer for the  
output of the transconductance amplifier. The current feed-  
back amplifier maintains its wide bandwidth over a wide  
range of voltage gains making it easy to interface the  
transconductance amplifier output to other circuitry. The  
current feedback amplifier is designed to drive low imped-  
ance loads, such as cables, with excellent linearity at high  
frequencies.
