ISL21009 (R) Data Sheet September 12, 2007 High Voltage Input Precision, Low Noise FGATM Voltage References The ISL21009 FGATM voltage references are extremely low power, high precision, and low noise voltage references fabricated on Intersil's proprietary Floating Gate Analog technology. The ISL21009 features very low noise (4.5VP-P for 0.1Hz to 10Hz), low operating current (180A, Max), and 3ppm/C of temperature drift. In addition, the ISL21009 family features guaranteed initial accuracy as low as 0.5mV. This combination of high initial accuracy, low power and low output noise performance of the ISL21009 enables versatile high performance control and data acquisition applications with low power consumption.

Over the specified temperature range. Temperature coefficient is measured by the box method whereby the change in VOUT is divided by the temperature range; in this case, -40C to +125C = +165C. 5. Thermal Hysteresis is the change of VOUT measured @ TA = +25C after temperature cycling over a specified range, TA. VOUT is read initially at TA = +25C for the device under test. The device is temperature cycled and a second VOUT measurement is taken at +25C. The difference between the initial VOUT reading and the second VOUT reading is then expressed in ppm. For TA = +165C, the device under test is cycled from +25C to +125C to -40C to +25C. 6. Long term drift is logarithmic in nature and diminishes over time. Drift after the first 1000 hours will be approximately 10ppm/sqrt(1kHrs). 5 FN6327.6 ISL21009 Small Outline Plastic Packages (SOIC) M8.15 (JEDEC MS-012-AA ISSUE C) N 8 LEAD NARROW BODY SMALL OUTLINE PLASTIC PACKAGE INDEX AREA H 0.25(0.010) M B M INCHES E SYMBOL -B1 2 3 L SEATING PLANE -A- A D h x 45 -C- e A1 B 0.25(0.010) M C 0.10(0.004) C A M MIN MAX MIN MAX NOTES A 0.0532 0.0688 1.35 1.75 - A1 0.0040 0.0098 0.10 0.25 - B 0.013 0.020 0.33 0.51 9 C 0.0075 0.0098 0.19 0.25 - D 0.1890 0.1968 4.80 5.00 3 E 0.1497 0.1574 3.80 4.00 4 e B S 0.050 BSC 1.27 BSC - H 0.2284 0.2440 5.80 6.20 - h 0.0099 0.0196 0.25 0.50 5 L 0.016 0.050 0.40 1.27 6 N a NOTES: MILLIMETERS 8 0 8 8 0 7 8 - 1.
