LT6600-15

Very Low Noise, Differential

Ampliﬁer and 15MHz Lowpass Filter

FEATURES

DESCRIPTION

TheLT^®6600-15combinesafullydifferentialampliﬁerwitha

4thorder15MHzlowpassﬁlterapproximatingaChebyshev

frequency response. Most differential ampliﬁers require

many precision external components to tailor gain and

Programmable Differential Gain via Two External

Resistors

Adjustable Output Common Mode Voltage

Operates and Speciﬁed with 3V, 5V, 5V Supplies

0.5dB Ripple 4th Order Lowpass Filter with 15MHz

Cutoff

76dB S/N with 3V Supply and 2V Output

bandwidth. In contrast, with the LT6600-15, two external

resistors program differential gain, and the ﬁlter’s 15MHz

cutoff frequency and passband ripple are internally set.

The LT6600-15 also provides the necessary level shifting

to set its output common mode voltage to accommodate

the reference voltage requirements of A/Ds.

10MHz: 63dBc 2nd, 69dBc 3rd

Fully Differential Inputs and Outputs

Compatible with Popular Differential Ampliﬁer

Using a proprietary internal architecture, the LT6600-15

integrates an antialiasing ﬁlter and a differential ampliﬁer/

driverwithoutcompromisingdistortionorlownoiseperfor-

mance. Atunitygainthemeasuredinbandsignal-to-noise

ratio is an impressive 76dB. At higher gains the input

referred noise decreases so the part can process smaller

input differential signals without signiﬁcantly degrading

the output signal-to-noise ratio.

APPLICATIONS

High Speed ADC Antialiasing and DAC Smoothing in

Networking or Cellular Base Station Applications

The LT6600-15 also features low voltage operation. The
