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.

Note 2: Connecting any pin to voltages greater than V

+ or less than V–

may cause latch-up. It is recommended that no sources operating from

external supplies be applied prior to power-up of the LTC1164-6.

Note 3: All gains are measured relative to passband gain.

Note 4: The cutoff frequency of the filter is abbreviated as fCUTOFF or fC.

HARA TERISTICS The ● denotes specifications that apply over the full operating temperature

range, otherwise specifications are at TA = 25°C. VS = ±7.5V, RL = 10k, TA = 25°C, fCLK = 400kHz, TTL or CMOS level (maximum clock

rise or fall time

≤ 1µs) and all gain measurements are referenced to passband gain, unless otherwise specified. (fCLK/fCUTOFF) = 4kHz

at 100:1 and 8kHz at 50:1.
