The LT6402-6 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 LT6402-6 an excellent solution for driving high speed 12-bit and 14-bit ADCs. In addition to the normal unfiltered outputs (+OUT and - OUT), the LT6402-6 has a built-in 75MHz differential low pass filter and an additional pair of filtered outputs (+OUTFILTERED, - OUTFILTERED) to reduce external filtering ponents when driving high speed ADCs. The output mon mode voltage is easily set via the VOCM pin, eliminating an output transformer or AC-coupling capacitors in many applications. The LT6402-6 is designed to meet the demanding requirements of munications 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 LT6402-6 can be used in data acquisition systems required to function at frequencies down to DC. The LT6402-6 operates on a 5V supply and consumes 30m A. It es in a pact 16-lead 3mm × 3mm QFN package and operates over a - 40°C to 85°C temperature range.
