LT1993-10

700MHz Low Distortion, Low

Noise Differential Ampliﬁer/

ADC Driver (A_V= 10V/V)

DESCRIPTIO

FEATURES

The LT^®1993-10 is a low distortion, low noise Differential

Ampliﬁer/ADC driver for use in applications from DC to

700MHz. The LT1993-10 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

LT1993-10 an excellent solution for driving high speed

12-bitand14-bitADCs.Inadditiontothenormalunﬁltered

outputs (+OUT and –OUT), the LT1993-10 has a built-in

175MHz differential lowpass ﬁlter and an additional pair

of ﬁltered outputs (+OUTFILTERED, –OUTFILTERED) to

reduce external ﬁltering components when driving high

speedADCs.Theoutputcommonmodevoltageiseasilyset
