LT6402-20

The LT^®6402-20 is a low distortion, low noise differential amplifi er/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 unfi ltered outputs (+OUT and OUT), the LT6402-20 has a built-in 75MHz differential low pass fi lter and an additional pair of fi ltered outputs (+OUTFILTERED, OUTFILTERED) to reduce external fi ltering components when driving high speed ADCs. The output common mode voltage is easily set via the V_OCM pin, eliminating an output transformer or ACcoupling capacitors in many applications.

The LT6402-20 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. The device 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 40ºC to 85ºC temperature range.
