LT1993-2

800MHz Low Distortion, Low

Noise Differential Ampliﬁer/

ADC Driver (A = 2V/V)

DESCRIPTIO

FEATURES

■

800MHz –3dB Bandwidth

The LT^®1993-2 is a low distortion, low noise Differential

Ampliﬁer/ADC driver for use in applications from DC to

800MHz. The LT1993-2 has been designed for ease of

use, with minimal support circuitry required. Exception-

ally low input-referred noise and low distortion products

(with either single-ended or differential inputs) make the

LT1993-2 an excellent solution for driving high speed 12-

bit and 14-bit ADCs. In addition to the normal unﬁltered

outputs (+OUT and –OUT), the LT1993-2 has a built-in

175MHz differential low pass ﬁlter and an additional pair

of ﬁltered outputs (+OUTFILTERED, –OUTFILTERED) to

reduce external ﬁltering components when driving high

speedADCs.Theoutputcommonmodevoltageiseasilyset

Differential ADC Driver for:

The LT1993-2 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 any other application requir-

ing differential drive. The LT1993-2 can be used in data

acquisition systems required to function at frequencies

down to DC.
