NOTES:
1. Over the specified temperature range. Temperature coefficient is measured by the box method whereby the change in V_OUT is divided by the
temperature range: (-40°C to +85°C = +125°C, or -40°C to +105°C = +145°C for the ISL60002-33).
2. Thermal Hysteresis is the change in V_OUT measured @ T_A = +25°C after temperature cycling over a specified range, ∆T_A, V_OUT is read initially
at T_A = +25°C for the device under test. The device is temperature cycled and a second V_OUT measurement is taken at +25°C. The difference
between the initial V_OUT reading and the second V_OUT reading is then expressed in ppm. For ∆T_A = +125°C, the device under is cycled from
+25°C to +85°C to -40°C to +25°C, and for ∆T_A = +145°C, the device under is cycled from +25°C to +105°C to -40°C to +25°C
3. Guaranteed by device characterization and/or correlation to other device tests.
4. FGA™ voltage reference long term drift is a logarithmic characteristic. Changes that occur after the first few hundred hours of operation are
significantly smaller with time, asymptotically approaching zero beyond 2000 hours. Because of this decreasing characteristic, long-term drift is
specified in ppm/√1kHr.
5. Pb-free manufacturing can result in solder reflow temperatures exceeding the +225°C absolute maximum. Exposing the device to this reflow
temperature will not damage it or cause any functional issues and the device will operate normally. The high reflow temperature may result in
a permanent shift in output voltage of 500µV to 1.0mV depending on the temperature and exposure time. If possible, using a reduced reflow
temperature in production will result in the best possible output voltage accuracy.
