All tests, after 3 minute warm-up period, at +15 V supplies and 2 kQ load to common unless otherwise specified. All measurements are referenced to Pin 7 of the device. Output voltage error as a function of temperature is determined using the box method. Each unit is tested at Thins Tmax and +25C. At each temperature Vour must fall within the rectangular area bounded by the minimum and maximum temperature and whose maximum Vout Value is equal to Voy nominal plus or - minus the maximum +25C error plus the maximum drift error from + 25C. 3See Figure | for trim circuits. 17-28 VOLTAGE REFERENCES REV.
