LT1256CS#PBF

LT ®1256 is a 2-input, 1-output, 40MHz current feedback amplifier with a linear control circuit that sets the amount each input contributes to the output. This part make excellent electronically controlled variable gain amplifiers, filters, mixers and faders. The only external components required are the power supply bypass capacitors and the feedback resistors. Typical applications include composite video gain control, RGB, YUV video gain control, video faders, keyers, gamma correction amplifiers, audio gain control, faders, multipliers, modulators and electronically tunable filters.

• Wide supply range: ±2.5V to ±15V, 13.5mA typ supply current at VC = VFS = 2.5V, VS = ±5V
• Accurate linear gain control: ±1% typ, ±3% max
• Constant gain with temperature
• Wide bandwidth: 40MHz at VS = ±15V, 0°C ≤ TA ≤ 70°C, VS = ±5V, VIN = 1VRMS, f = 1kHz
• 300V/µs typ slew rate at VIN = ±2.5V, VO at ±2V, RL = 150 ohm, 0°C ≤ TA ≤ 70°C
• 0.02%/0.02° typ differential gain/phase at control = 0% or 100%
• 0.002% typ total harmonic distortion at gain = 100%
• 65ns typ setting time at 0.1%, ∆VO = 2V, 0°C ≤ TA ≤ 70°C
• 14 lead SOIC package
• Operating temperature range from -40 to 85°C
