DESCRIPTION
Dual Very Low Noise,
Differential Amplier and
2.5MHz Lowpass Filter
The LT6604-2.5 consists of two matched, fully differential
ampliers, each with a 4th order, 2.5MHz lowpass lter. The
xed frequency lowpass lter approximates a Chebyshev
response. By integrating a lter and a differential ampli-
er, distortion and noise are made exceptionally low. At
unity gain, the measured in-band signal-to-noise ratio is
an impressive 86dB. At higher gains, the input referred
noise decreases, allowing the part to process smaller
input differential signals without signicantly degrading
the signal-to-noise ratio.
Gain and phase are well matched between the two chan-
nels. Gain for each channel is independently programmed
using two external resistors. The LT6604-2.5 enables level
shifting by providing an adjustable output common mode
voltage, making it ideal for directly interfacing to ADCs.
The LT6604-2.5 is fully specied for 3V operation. The
differential design enables outstanding performance up
to a 4VP-P signal level for a single 3V supply.
See the back page of this datasheet for a complete list of
related single and dual differential ampliers with integrated
2.5MHz to 20MHz lowpass lters.
