Frequency Response
Single 3.3V Supply 3kHz Elliptic Lowpass Filter
TYPICAL APPLICATION
DESCRIPTION
Low Power, 8th Order
Progressive Elliptic,
Lowpass Filter
The LTC1069-1 is a monolithic 8th order lowpass lter
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 lter 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.
