LT6402-6

300MHz Low Distortion, Low

Noise Differential Amplifier/

amplifier/ADC driver for use in applications from DC to

300MHz. 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 fil-

tering components when driving high speed ADCs. The

pin, eliminating an output transformer or AC-coupling

capacitors in many applications.

The LT6402-6 is designed to meet the demanding require-

ments of communications transceiver applications. It can

be used as a differential ADC driver, a general-purpose

differential gain block, or in other applications requir-

ing differential drive. The LT6402-6 can be used in data

acquisition systems required to function at frequencies

down to DC.

TheLT6402-6operatesona5Vsupplyandconsumes30mA.

It comes in a compact 16-lead 3mm × 3mm QFN package

and operates over a –40°C to 85°C temperature range.
