The cutoff frequency (f
CUTOFF
) of the LTC1069-1 is equal
to the clock frequency divided by 100. The gain at f
CUTOFF
is –0.7dB and the typical passband ripple is
±
0.15dB
up to 0.9f
CUTOFF
. The stopband attenuation of the
LTC1069-1 features a progressive elliptic response
reaching 20dB attenuation at 1.2f
CUTOFF
, 52dB attenua-
tion at 1.4f
CUTOFF
and 70dB attenuation at 2f
CUTOFF
.
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 0.3V
RMS
to 2.5V
RMS
, the signal-to-(noise
+ THD) ratio is
≥
70dB. The wideband noise of the
LTC1069-1 is 110
μ
V
RMS
.
Other filter responses with
lower power or higher speed can be obtained. Please
contact LTC marketing for details.
The LTC1069-1 is available in 8-pin PDIP and 8-pin SO
packages.

ESCRIPTIO
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.
