LTC6603
ELECTRICAL CHARACTERISTICS
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 specified performance from
0°C to 70°C. The LTC6603C is designed, characterized and expected to
meet specified performance from –40°C to 85°C but is not tested or QA
sampled at these temperatures. The LTC6603I is guaranteed to meet the
specified performance limits from –40°C to 85°C.
Note 4: This test measures the internal oscillator accuracy (deviation from
the fCLK equation). Variations in the internal oscillator cause variations in
the filter cutoff frequency. See the “Applications Information” section.
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.
