These are stress ratings provided for information only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specifica- tion are not implied.

ELECTRICAL CHARACTERISTICS

(Operating Conditions: V IN = 5.0V, IOUT = 0mA, COUT = 0.001µF, TA = -40 to +85°C unless otherwise specified.) Note: 1. Over the specified temperature range. Temperature coeffi cient is measured by the box method whereby the change in VOUT is divided by the temperature range; in this case, -40°C to +85°C = 125°C. 2. Thermal Hysteresis is the change in V OUT created by package stress @ TA = 25°C after temperature cycling. VOUT is read initially at TA = 25°C; the X60003x-41 is then cycled between Hot (85°C) and Cold (-40°C) before a second VOUT measurement is taken at 25°C. The deviation between the initial VOUT reading and the second VOUT reading is then expressed in ppm. 3. Guaranteed by Device Characterization and/or correlation to other device tests.

7 FN8138.0 March 15, 2005 APPLICATIONS INFORMATION FGA Technology The X60003x-41 voltage reference uses the floating gate technology to create references with very low drift and supply current. Essentially the charge stored on a floating gate cell is set precisely in manufacturing. The reference voltage output itself is a buffered version of the floating gate voltage. The resulting reference device has excellent char acteristics which are unique in the industry: very low temperature drift, high initial accu- racy, and almost zero supply current. Also, the refer- ence voltage itself is not limited by voltage bandgaps or zener settings, so a wide range of reference voltages can be programmed (standard voltage settings are pro- vided, but customer-specific voltages are available). The process used for these reference devices is a floating gate CMOS process, and the amplifier circuitry uses CMOS transistors for amplifier and output tran- sistor circuitry. While pr oviding excellent accuracy, there are limitations in output noise level and load reg- ulation due to the MOS devi ce characteristics. These limitations are addressed with circuit techniques dis- cussed in other sections. Nanopower Operation Reference devices achiev e their highest accuracy when powered up continuously, and after initial stabili- zation has taken place. The X60003x-41 is the first high precision voltage ref- erence with ultra low power consumption that makes it practical to leave power-on continuously in battery operated circuits. The X60003x-41 consumes extremely low supply current due to the proprietary FGA technology. Supply current at room temperature is typically 500nA which is 1 to 2 orders of magnitude lower than competitive dev ices. Application circuits using battery power will benefit greatly from having an accurate, stable reference which essentially presents no load to the battery. In particular, battery powered data converter circuits that would normally require the entire circuit to be dis- abled when not in use can remain powered up between conversions as shown in figure 1. Data acqui- sition circuits providing 12 to 24 bits of accuracy can operate with the reference de vice continuously biased with no power penalty, providing the highest accuracy and lowest possible long term drift. Other reference devices consuming higher supply cur- rents will need to be disabl ed in between conversions to conserve battery capaci ty. Absolute accuracy will suffer as the device is biased and requires time to set- tle to its final value, or, may not actually settle to a final value as power-on time may be short. Figure 1. Board mounting Considerations For applications requiring the highest accuracy, board mounting location should be reviewed. Placing the device in areas subject to slight twisting can cause degradation of the accuracy of the reference voltage due to die stresses. It is normally best to place the device near the edge of a board, or the shortest side, as the axis of bending is mo st limited at that location. Obviously mounting the device on flexprint or extremely thin PC material will likewise cause loss of reference accuracy. Noise Performance and Reduction: The output noise voltage in a 0.1Hz to 10Hz bandwidth is typically 30µVp -p. This is shown in the plot in the Typical Performance Curves. The noise measurement is made with a bandpass filter made of a 1 pole high-pass filter with a corner frequency at .1Hz and a 2-pole low-pass filter with a corner frequency at 12.6Hz to create a filter with a 9.9Hz bandwidth. Noise in the 10KHz to 1MHz bandwidth is approximately 400µVp-p with no capacitance on the output, as shown in Fig. 2 below. These noise measurements are made with a 2 decade bandpass filter made of a 1 pole high-pass filter with a corner frequency at 1/10 of the center frequency and 1-pole low-pass filter with a corner frequency at 10 times the center frequency. Figure 2 also shows the noise in the 10KHz to 1MHz band can be reduced to about 50µVp- p using a .001µF capacitor on the output. Noise in the 1KHz to 100KHz band can be further reduced using a 0.1µF capacitor on the output, but noise in the 1Hz to 100Hz band increases due to instability of the very low power amplifier with a 0.1µF capacitance load.
