.. Features - - - LT6402-20 300MHz Low Distortion, Low Noise Differential Amplifier/ADC Driver (AV = 20d B) DESCRIPTIO The LT®6402-20 is a low distortion, low noise differential amplifier/ADC driver for use in applications from DC to 300MHz. The LT6402-20 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 ponents when driving high speed ADCs. The output mon mode voltage is easily set via the VOCM pin, eliminating an output transformer or ACcoupling capacitors in many applications. The LT6402-20 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 LT6402-20 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 30m A. It es in a pact 16-lead 3mm × 3mm QFN package and operates over a - 40ºC to 85ºC temperature range. - - - - - - - 300 MHz - 3d B Bandwidth Fixed Gain of 20d B Low Distortion: 48.5d Bm OIP3, - 81d Bc HD3 (20MHz, 2VP-P) Low Noise: 12.4d B NF, en = 1.9n V/√Hz (20MHz) Differential Inputs and Outputs Additional Filtered Outputs Adjustable Output mon Mode Voltage DC- or AC-Coupled Operation Minimal Support Circuitry Required Small 0.75mm Profile 16-Lead 3mm × 3mm QFN Package U APPLICATIO S - - - - - - - Differential ADC Driver for: Imaging munications Differential Driver/Receiver Single Ended to Differential Conversion...
