The
● denotes the specifications which apply over the full operating temperature range, otherwise specifications are at VS = ±7.5V,
RL = 1k, TA = 25°C, fCLK signal level is TTL or CMOS (maximum clock rise or fall time ≤ 1s) unless otherwise specified. All AC gain
measurements are referenced to passband gain.
