ELECTRICAL CHARACTERISTICS
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.
The l denotes the specifi cations which apply over the full operating
temperature range, otherwise specifi cations are at T
A
= 25°C. f
CUTOFF
is the fi lter’s cutoff frequency and is equal to f
CLK
/100. The
f
CLK
signal level is TTL or CMOS (clock rise or fall time ≤ 1μs), V
S
= 3.3V to ±5V, R
L
= 10k, unless otherwise noted. All AC gains are
measured relative to the passband gain.
