ADI LT6402CUD-20#TRPBF

The LT6402 - 20 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 LT6402 - 20 an excellent solution for driving high speed 12 - bit and 14 - bit ADCs. In addition to the normal unfiltered outputs (+OUT and –OUT), the LT6402 - 20 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. The output common mode voltage is easily set via the VOCM pin, eliminating an output transformer or AC - coupling capacitors in many applications. It is designed to meet the demanding requirements of communications transceiver applications. It can be used as a differential ADC driver, a general - purpose differential gain block, or in other applications requiring differential drive. It can be used in data acquisition systems required to function at frequencies down to DC. The LT6402 - 20 operates on a 5V supply and consumes 30mA. It comes in a compact 16 - lead 3mm × 3mm QFN package and operates over a - 40°C to 85°C temperature range.
