The LTC1560-1, unlike other high frequency filters, is
designed for low noise and low distortion. With a 1V
input signal, the signal-to-noise ratio is 69dB and the THD
is – 63dB. The maximum SNR of 75dB is obtained with a

The LTC1560-1 operates with 5V supplies, has a power
saving mode and is available in an SO-8 surface mount
package.
Other cutoff frequencies from 450kHz to 1.5MHz can be
obtained. Demo board DC135A is available for the
LTC1560-1. For more information please contact LTC
