ELECTRICAL CHARACTERISTICS Note 1:
Stresses beyond those listed under Absolute Maximum Ratings is 10 sec. RMS noise is measured with a single pole highpass filter at may cause permanent damage to the device. Exposure to any Absolute 10Hz and a 2-pole lowpass filter at 1kHz. The resulting output is full wave Maximum Rating condition for extended periods may affect device rectified and then integrated for a fixed period, making the final reading an reliability and lifetime. average as opposed to RMS. A correction factor of 1.1 is used to convert
Note 2:
The LT6660 is guaranteed functional over the operating from average to RMS and a second correction of 0.88 is used to correct temperature range of –40°C to 85°C. for the nonideal bandpass of the filters.
Note 3:
If the parts are stored outside of the specified temperature range,
Note 9:
Long-term stability typically has a logarithmic characteristic the output may shift due to hysteresis. and therefore, changes after 1000 hours tend to be much smaller than
Note 4:
Temperature coefficient is measured by dividing the change in before that time. Total drift in the second thousand hours is normally less output voltage by the specified temperature range. Incremental slope is than one third that of the first thousand hours with a continuing trend also measured at 25°C. toward reduced drift with time. Long-term stability will also be affected by differential stresses between the IC and the board material created during
Note 5:
Load regulation is measured on a pulse basis from no load to the board assembly. specified load current. Output changes due to die temperature change must be taken into account separately.
Note 10:
Hysteresis in output voltage is created by package stress that differs depending on whether the IC was previously at a higher or lower
Note 6:
Thermal regulation is caused by die temperature gradients created temperature. Output voltage is always measured at 25°C, but the IC by load current or input voltage changes.
