DESCRIPTION
The LTC
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 (f
to the clock frequency divided by 100. The gain at f
is –0.7dB and the typical passband ripple is ±0.15dB up
to 0.9f
features a progressive elliptic response reaching 20dB
attenuation at 1.2f
and 70dB attenuation at 2f
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
THD) ratio is ≥70dB. The wideband noise of the LTC1069-1
is 110μV
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.

... APPLICATIONS INFORMATION Temperature Behavior The power supply current of the LTC1069-1 has a positive temperature coeffi cient. The GBW product of its internal op amps is nearly constant and the speed of the device does not degrade at high temperatures. Figures 3a, 3b and 3c show the behavior of the maximum passband of the device for various supplies and temperatures. The fi ...

... Aliasing Aliasing is an inherent phenomenon of sampled data systems and it occurs for input frequencies approaching the sampling frequency. The internal sampling frequency of the LTC1069-1 is 100 times its cutoff frequency. For instance 98kHz, 100mV signal is applied at the RMS input of an LTC1069-1 operating with a 100kHz clock, a 2kHz, 28μ ...
