Linear Technology LT1256 40MHz Video Fader and DC Gain Controlled Amplifier. The LT1256 are 2-input, 1-output current feedback amplifiers with a linear control circuit. Typical applications include variable gain amplifiers, filters, mixers and faders.

Choosing LT1251 vs LT1256: 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%, LT1251 sets one input completely off and the other completely on, eliminating off-channel feedthrough due to offset or gain errors in the control signals. The LT1256 does not have this on/off feature and operates linearly over the complete control range. LT1256 is therefore recommended for applications requiring more than 20dB of linear control range.
