LTC1069-7
ELECTRICAL CHARACTERISTICS The l denotes specifications which apply over the full operating
temperature range. fCUTOFF is the filter’s cutoff frequency and is equal to fCLK/25. The fCLK signal level is TTL or CMOS (max clock rise
or fall time ≤ 1μs), RL = 10k, TA = 25°C, unless otherwise specified. All AC gains are measured relative to the passband gain.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Phase Deviation = 1/2(Phase at 0Hz – Phase at fCUTOFF) – (Phase
at 0Hz – Phase at 0.5fCUTOFF)
Phase at 0Hz = 180° (guaranteed by design)
Example: An LTC1069-7 has Phase at 0.5fCUTOFF = – 30.5° and Phase at
fCUTOFF = –235°.
Passband Phase Deviation from Linear Phase
= 1/2[180° – (–235°)] – [(180° – (–30.5°)] = –3°
