–20dB at 1.2f_CUTOFF

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-

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.

input range of 0.3V_RMSto 2.5V_RMS, the signal-to-(noise

+ THD) ratio is ≥70dB. The wideband noise of the

LTC1069-1 is 110µV_RMS. Other filter responses with

lower power or higher speed can be obtained. Please
