Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 5:
To conform with the Logic IC Standard convention, current out of may cause permanent damage to the device. Exposure to any Absolute a pin is arbitrarily given as a negative value. Maximum Rating condition for extended periods may affect device
Note 6:
Output rise and fall times are measured between the 10% and 90% reliability and lifetime. power supply levels. These specifi cations are based on characterization.
Note 2:
Frequencies near 100kHz and 1MHz may be generated using two
Note 7:
Guaranteed by 5V test. different values of RSET (see the Selecting the Divider Setting Resistor
Note 8:
The LTC6900C is guaranteed to meet specifi ed performance from paragraph in the Applications Information section). For these frequencies, 0°C to 70°C. The LTC6900C is designed, characterized and expected to the error is specifi ed under the following assumption: 20k < RSET ≤ 200k. meet specifi ed performance from – 40°C to 85°C but is not tested or
Note 3:
Frequency accuracy is defi ned as the deviation from the QA sampled at these temperatures. The LTC6900I is guaranteed to meet fOSC equation. specifi ed performance from –40°C to 85°C.
Note 4:
Jitter is the ratio of the peak-to-peak distribution of the period to the mean of the period. This specifi cation is based on characterization and is not 100% tested. Also, see the Peak-to-Peak Jitter vs Output Frequency curve in the Typical Performance Characteristics section. 6900fa 3
