LT1251/LT1256  
40MHz Video Fader and  
DC Gain Controlled Amplifier  
U
FEATURES  
DESCRIPTION  
The LT®1251/LT1256 are 2-input, 1-output, 40MHz cur-  
rent feedback amplifiers with a linear control circuit that  
sets the amount each input contributes to the output.  
These parts make excellent electronically controlled vari-  
able gain amplifiers, filters, mixers and faders. The only  
external components required are the power supply by-  
pass capacitors and the feedback resistors. Both parts  
operate on supplies from ±2.5V (or single 5V) to ±15V  
(or single 30V).  
■
Accurate Linear Gain Control: ±1% Typ, ±3% Max  
■
Constant Gain with Temperature  
Wide Bandwidth: 40MHz  
High Slew Rate: 300V/µs  
Fast Control Path: 10MHz  
Low Control Feedthrough: 2.5mV  
High Output Current: 40mA  
Low Output Noise

45nV/√Hz at AV = 1  
270nV/√Hz at AV = 100  
Low Distortion: 0.01%  
Wide Supply Range: ±2.5V to ±15V  
Low Supply Current: 13mA  
Low Differential Gain and Phase: 0.02%, 0.02°  
Absolute gain accuracy is trimmed at wafer sort to mini-  
mize part-to-part variations. The circuit is completely  
temperature compensated.

The LT1251 includes circuitry that eliminates the need for  
accurate control signals around zero and full scale. For  
control signals of less than 2% or greater than 98%, the  
LT1251 sets one input completely off and the other  
completely on. This is ideal for fader applications because  
it eliminates off-channel feedthrough due to offset or gain  
errors in the control signals.

TheLT1256doesnothavethison/offfeatureandoperates  
linearly over the complete control range. The LT1256 is  
recommended for applications requiring more than 20dB  
of linear control range.
