CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
For guaranteed specifications and test conditions, see Electrical Specifications.
The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed
test conditions.
NOTES:
1. Maximum duration = 10s.
2. θ_JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
3. Post-reflow drift for the ISL21032 devices will range from 100µV to 1.0mV based on experimental results with devices tested in sockets and also
on FR4 multi-layer PC boards. The design engineer must take this into account when considering the reference voltage after assembly.
Electrical Specifications (VOUT = 0.600V) Operating Conditions: V_IN = 3.0V, I_OUT = 0mA, C_OUT = 0.001µF, T_A = -40 to +130°C,
unless otherwise specified.

NOTES:
4. Thermal Hysteresis is the change in V_OUT measured @ T_A = +25°C after temperature cycling over a specified range, ΔT_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 ΔT_A = 170°C, the device
under is cycled from +25°C to +130°C to -40°C to +25°C.
5. Limits are established by full device characterization over temperature range and are not tested in production.
6. 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.
