LTC1164-7

Low Power, Linear Phase

8th Order Lowpass Filter

DESCRIPTIO

EATURE

■

Better Than Bessel Roll-Off

The LTC1164-7 is a low power, clock-tunable monolithic

8th order lowpass filter with linear passband phase and

flat group delay. The amplitude response approximates a

maximally flat passband and exhibits steeper roll-off than

an equivalent 8th order Bessel filter. For instance, at twice

the cutoff frequency the filter attains 34dB attenuation

(vs12dB for Bessel), while at three times the cutoff fre-

quency the filter attains 68dB attenuation (vs 30dB for

Bessel). The cutoff frequency of the LTC1164-7 is tuned

via an external TTL or CMOS clock.

f_CUTOFFup to 20kHz, Single 5V Supply

PPLICATI

Low power is achieved without sacrificing dynamic range.

With single 5V supply, the S/N + THD is up to 75dB.

Optimum 91dB S/N is obtained with ±7.5V supplies.

Phase Matched Filters

The clock-to-cutoff frequency ratio of the LTC1164-7 can

be set to 50:1 (pin 10 to V⁺) or 100:1 (pin 10 to V^–).

When the filter operates at the clock-to-cutoff frequency

ratio of 50:1, the input is double-sampled to lower the risk

of aliasing.

The LTC1164-7 is pin-compatible with the LTC1064-X

series and LTC1264-7.
