These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) − TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability. 2. The package thermal impedance is calculated in accordance with JESD 51-7. recommended operating conditions MIN MAX UNIT TA Operating free-air temperature LT1004C 0 70 °C TA Operating free-air temperature LT1004I −40 85 °C electrical characteristics at specified free-air temperature PARAMETER TEST TA‡ LT1004-1.2 LT1004-2.5 UNIT PARAMETER TEST CONDITIONS TA‡ MIN TYP MAX MIN TYP MAX UNIT 25 °C 1.231 1.235 1.239 2.48 2.5 2.52 VZ Reference voltage IZ = 100 µA Full LT1004C 1.225 1.245 2.47 2.53 V VZ Reference voltage IZ = 100 µA Full range LT1004I 1.225 1.245 2.47 2.53 V a V Average temperature coefficient IZ = 10 µA 25 °C 20 ppm/ °C a V Z temperature coefficient of reference voltage§ IZ = 20 µA 25 °C 20 ppm/ °C Change in IZ = IZ(min) to 1 mA 25 °C 1 1 ∆VZ Change in reference voltage IZ = IZ(min) to 1 mA Full range 1.5 1.5 mV ∆VZ reference voltage with current IZ = 1 mA to 20 mA 25 °C 10 10 mV with current IZ = 1 mA to 20 mA Full range 20 20 ∆VZ/∆t Long-term change in reference voltage IZ = 100 µA 25 °C 20 20 ppm/khr IZ(min) Minimum reference current Full range 8 10 12 20 µA zz Reference impedance IZ = 100 A 25 °C 0.2 0.6 0.2 0.6 Ω zz Reference impedance IZ = 100 µA Full range 1.5 1.5 Ω Vn Broadband noise voltage IZ = 100 µA, f = 10 Hz to 10 kHz 25 °C 60 120 µV ‡ Full range is 0°C to 70°C for the LT1004C and −40°C to 85°C for the LT1004I. § The average temperature coefficient of reference voltage is defined as the total change in reference voltage divided by the specified temperature range. |
