• Small 0.75mm Profi le 16-Lead 3mm × 3mm QFN Package Description of the small 0.75mm Profi le 16-Lead 3mm x 3mm QFN package The LT6402-20 is a low distortion, low noise differential amplifier/ADC driver for use in applications from DC to 300MHz. The LT6402-20 is a low-distortion, low-noise differential amplifier/ADC driver for applications from DC to 300MHz. The LT6402-20 has been designed for ease of use, with minimal support circuitry required. The LT6402-20 has been designed to be easy to 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. With very low input noise and low distortion (single-ended or differential input), it is an excellent solution for driving the LT6402-20 for 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. In addition to the normally filtered 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 elements while driving high-speed ADCs. The output common mode voltage is easily set via the V OCM pin, eliminating an output transformer or AC-coupling capacitors in many applications. Easily set the output common-mode voltage via the V OCM pin, eliminating the need for output transformers or AC-coupled capacitors in many applications. The LT6402-20 is designed to meet the demanding requirements of communications transceiver applications. The LT6402-20 is designed to meet the demanding requirements of communication transceiver applications. It can be used as a differential ADC driver, a general-purpose differential gain block, or in other applications requiring differential drive. The LT6402-20 can be used in data acquisition systems required to function at frequencies down to DC. The LT6402-20 can be used in data acquisition systems to function when frequency drops to DC. The LT6402-20 operates on a 5V supply and consumes 30mA. LT6402-20 has a 5V power supply and consumes 30 mA. It comes in a compact 16-lead 3mm × 3mm QFN package and operates over a –40ºC to 85ºC temperature range×.
