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 specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C. fCUTOFF is the filter’s cutoff frequency and is equal to fCLK/100. The

fCLK signal level is TTL or CMOS (clock rise or fall time ≤ 1μs), VS = 3.3V to ±5V, RL = 10k, unless otherwise noted. All AC gains are

measured relative to the passband gain.
