LT6402CUD-6#PBF

LT6402CUD-6#PBF is a low distortion, low noise differential amplifier/ADC driver for use in applications from DC to 300MHz. It has been designed for ease of use, with minimal support circuitry required. Exceptionally low input-referred noise and low distortion (with either single-ended or differential inputs) make the device an excellent solution for driving high-speed 12bit and 14bit ADCs. In addition to the normal unfiltered outputs (+OUT and –OUT), the LT6402-6 has a built-in 75MHz differential low pass filter and an additional pair of filtered outputs (+OUTFILTERED, –OUTFILTERED) to reduce external filtering components when driving high-speed ADCs. It is also used in applications such as differential ADC driver for imaging, communications, differential driver/receiver, single-ended to differential conversion, differential to single-ended conversion, level shifting, IF sampling receivers, and SAW filter interfacing/buffering.

• Differential inputs and outputs, additional filtered outputs
• Adjustable output common mode voltage, DC- or AC-coupled operation
• Gain is 6dB typical at (differential (+OUT, –OUT), VIN = ±800mV differential)
• Input offset voltage is 1mV typical at (TA = 25°C, VCCA = VCCB = VCCC = 5V)
• 300MHz typical -3dB bandwidth at (TA = 25°C, VCCA = VCCB = VCCC = 5V)
• Slew rate is 400V/μs typical at (TA = 25°C, VCCA = VCCB = VCCC = 5V)
• Supply current is 30mA typical at (ENABLE = 0.8V, TA = 25°C)
• Power supply rejection ratio is 90dB typical at (4V to 5.5V, TA = 25°C. VCCA = VCCB = VCCC = 5V)
• 1% settling is 10ns typical at (1% settling for a 1VP-P differential step (+OUT, –OUT))
• Operating temperature range from -40°C to 85°C, 16-lead plastic QFN package
