• Description: Dual Adjustable Lowpass Filter
• Manufacturer: Linear Technology

ELECTRICAL CHARACTERISTICS
LTC6603
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: LTC6603C and LTC6603I are guaranteed functional over the
operating temperature range of –40°C to 85°C.
Note 3: LTC6603C is guaranteed to meet specifi ed performance from
0°C to 70°C. The LTC6603C is designed, characterized and expected to
meet specifi ed performance from –40°C to 85°C but is not tested or QA
sampled at these temperatures. The LTC6603I is guaranteed to meet the
specifi ed performance limits from –40°C to 85°C.

Note 5: Guaranteed by design, not subject to test.
Note 6: To conform to the logic IC standard, current out of a pin is
arbitrarily given a negative value.
