either 500kHz (Pin 5 to V +) or 1MHz (Pin 5 to V –). When
programmed for 1MHz, the passband ripple is typically
±0.2dB up to 0.55fCUTOFF and ±0.3dB to 0.9fCUTOFF. The
transition band gain is – 24dB at 1.4fCUTOFF and – 51dB at
2fCUTOFF. Stopband attenuation is 63dB at 2.43fCUTOFF and
above, remaining at least 60dB to 10MHz with proper
board layout. When the LTC1560-1 is programmed for
fCUTOFF = 500kHz, the filter response closely follows the
1MHz case with the exception of passband flatness near
the cutoff frequency; the gain at fCUTOFF is – 1.3dB.
The LTC1560-1, unlike other high frequency filters, is
designed for low noise and low distortion. With a 1VRMS
input signal, the signal-to-noise ratio is 69dB and the THD
is – 63dB. The maximum SNR of 75dB is obtained with a
2.1VRMS input signal. This results in – 46dB THD.
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

DESCRIPTION
U
The LTC
1560-1 is a 5th order, continuous-time, lowpass
filter.
The elliptic transfer function of the LTC1560-1 was
carefully chosen to reach a compromise between selectiv-
ity, for antialiasing applications, and transient response.
The filter cutoff frequency, fCUTOFF, is pin selectable to
