LTC1565-31
ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VS = 5V, RLOAD = 10k from each output to AC ground, and Pin 5 open
unless otherwise specified.

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: Input and output voltages expressed as peak-to-peak numbers are
assumed to be fully differential.
Note 3: Output DC offset is measured between Pin 8 and Pin 7 with Pin 1
and Pin 2 connected to Pin 3.
Note 4: Thermal resistance varies depending upon the amount of PC board
metal attached to the device. θJA is specified for a 3.8 square inch test
board covered with 2 oz copper on both sides.
Note 5: Output DC offset measurements are performed by automatic test
equipment approximately 0.5 seconds after application of power.
