LTC1560-1

1MHz/500kHz

Continuous Time,

Low Noise, Lowpass Elliptic Filter

FEATURES

5th Order, 1MHz Elliptic Filter in SO-8 Package

Pin Selectable 1MHz/500kHz Cutoff Frequency

Signal-to-Noise Ratio (SNR): 75dB

Signal-to-Noise Ratio with – 63dB THD: 69dB

Passband Ripple (f

= 1MHz):

±0.3dB

Stopband Attenuation Better Than 60dB

No External Components Required

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 0.55f

CUTOFF

and

±0.3dB

to 0.9f

CUTOFF

. The

transition band gain is – 24dB at 1.4f

CUTOFF

and – 51dB at

CUTOFF

. Stopband attenuation is 63dB at 2.43f

CUTOFF

and

above, remaining at least 60dB to 10MHz with proper

board layout. When the LTC1560-1 is programmed for

CUTOFF

= 500kHz, the filter response closely follows the

1MHz case with the exception of passband flatness near

the cutoff frequency; the gain at f

CUTOFF

is – 1.3dB.

The LTC1560-1, unlike other high frequency filters, is

designed for low noise and low distortion. With a 1V

RMS

input signal, the signal-to-noise ratio is 69dB and the THD

is – 63dB. The maximum SNR of 75dB is obtained with a

2.1V

RMS

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

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, f

CUTOFF

, is pin selectable to
