LTC1164-8
ELECTRICAL CHARACTERISTICS (See Test Circuit)
TA = 25°C, Center Frequency = fCLK/100, fCLK = 100kHz ( the clock signal is a TTL or CMOS square wave, clock rise or fall time ≤ 1µs),
the AC test signal level is 1VRMS for VS = ±5V or 0.5VRMS for VS = ±2.375V, unless otherwise specified.

The q denotes specifications which apply over the full operating
temperature range.
Note 1: The minimum stopband attenuation at 960Hz and 1040Hz is
guaranteed by design and test correlation.
Note 2: The maximum current over temperature is at 0°C. At 70°C the
maximum current is less than its maximum value at 25°C.
