ELECTRICAL CHARACTERISTICS The ● denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VS = ±7.5V, RL = 10k, fCUTOFF = 100kHz or 50kHz, fCLK = 2.5MHz, TTL or
CMOS level (maximum clock rise or fall time ≤ 1µs) and all gain measurements are referenced to passband gain, unless otherwise
specified.
