TYPICAL APPLICATION

DESCRIPTION

Low Power, 8th Order

Progressive Elliptic,

Lowpass Filter

The LTC®1069-1 is a monolithic 8th order lowpass ﬁlter

featuring clock-tunable cutoff frequency and 2.5mA power

supply current with a single 5V supply. An additional feature

of the LTC1069-1 is operation with a single 3.3V supply.

The cutoff frequency (fCUTOFF) of the LTC1069-1 is equal

to the clock frequency divided by 100. The gain at fCUTOFF

is –0.7dB and the typical passband ripple is ±0.15dB up

to 0.9fCUTOFF. The stopband attenuation of the LTC1069-1

features a progressive elliptic response reaching 20dB

attenuation at 1.2fCUTOFF, 52dB attenuation at 1.4fCUTOFF

and 70dB attenuation at 2fCUTOFF.

With ±5V supplies, the LTC1069-1 cutoff frequency can

be clock-tuned up to 12kHz; with a single 5V supply, the

maximum cutoff frequency is 8kHz.

The low power feature of the LTC1069-1 does not penal-

ize the device’s dynamic range. With ±5V supplies and an

input range of 0.3VRMS to 2.5VRMS, the signal-to-(noise +

THD) ratio is ≥70dB. The wideband noise of the LTC1069-1

is 110μVRMS. Other ﬁlter responses with lower power or

higher speed can be obtained. Please contact LTC market-

ing for details.

The LTC1069-1 is available in 8-pin PDIP and 8-pin SO

packages.
