ISL21070

25μA Micropower Voltage References ISL21070 The ISL21070 voltage references are analog voltage references featuring low supply voltage operation at ultra-low 25μA max operating current. Additionally, the ISL21070 family features guaranteed initial accuracy as low as ±0.2% and 30ppm/°C temperature coefficient. These references are ideal for general purpose applications for performance at lower cost. The ISL21070 is provided in an industry standard 3 Ld SOT-23 pinout. The ISL21070 offers output voltages that can be used as precision voltage sources for control loops, standby voltages for low power states for DSP, FPGA, Data path Controllers, Microcontrollers and other core voltages: 0.600V, 2.048V, and 2.5V.

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, -40°C to +85°C = +125°C. 10. Thermal Hysteresis is the change of VOUT measured @ TA = +25°C after temperature cycling over a specified range, ΔTA. VOUT is read initially at TA = +25°C for the device under test. The device is temperature cycled and a second VOUT measurement is taken at +25°C. The difference between the initial VOUT reading and the second VOUT reading is then expressed in ppm. For Δ TA = +125°C, the device under test is cycled from +25°C to +85°C to -40°C to +25°C. 11. Long term drift is logarithmic in nature and diminishes over time. Drift after the first 1000 hours will be approximately 10ppm/√1khrs 12. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design. 4 FN7599.2 July 1, 2011 ISL21070 Typical Performance Characteristics Curves VOUT = 2.5V, VIN = 3V, IOUT = 0mA, TA = +25°C unless otherwise specified. 20 18 16 14 12 IIN (μA) 10 8 6 4 2 0 2.7 3.1 3.5 3.9 4.3 4.7 5.1 5.5 LOW IIN (μA) HIGH TYP 13 12 11 10 9 8 2.7 -40°C 3.1 3.5 3.9 4.3 4.7 5.1 5.5 -85°C +25°C 14 VIN (V) VIN (V) FIGURE 2.

VOUT NOISE, 0.1Hz TO 10Hz Applications Information FGA Technology The ISL21070 series of voltage references use 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 characteristics which are unique in the industry: very low temperature drift, high initial accuracy, and almost zero supply current. Also, the reference 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 provided, 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 transistor circuitry. While providing excellent accuracy, there are limitations in output noise level and load regulation due to the MOS device characteristics. These limitations are addressed with circuit techniques discussed in other sections. Handling and Board Mounting FGA references provide excellent initial accuracy and low temperature drift at the expense of very little power drain. There are some precautions to take to insure this accuracy is not compromised. Excessive heat during solder reflow can cause excessive initial accuracy drift, so the recommended +260°C max temperature profile should not be exceeded. Expect up to 1mV drift from the solder reflow process. FGA references are susceptible to excessive X-radiation like that used in PC board manufacturing. Initial accuracy can change 10mV or more under extreme radiation. If an assembled board needs to be X-rayed, care should be taken to shield the FGA reference device. FN7599.2 July 1, 2011 7 ISL21070 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 most limited at that location. Obviously, mounting the device on flexprint or extremely thin PC material will likewise cause loss of reference accuracy. If a device is expected to pass through luggage X-ray machines numerous times, it is advised to mount a 2-layer (minimum) PC board on the top, and along with a ground plane underneath will effectively shield it from 50 to 100 passes through the machine. Since these machines vary in X-ray dose delivered, it is difficult to produce an accurate maximum pass recommendation. Noise Performance and Reduction The output noise voltage in a 0.1Hz to 10Hz bandwidth is typically 30μVP-P . The noise measurement is made with a bandpass filter made of a 1 pole high-pass filter with a corner frequency at 0.1Hz and a 2-pole low-pass filter with a corner frequency at 12.6Hz to create a filter with a 9.9Hz bandwidth. Wideband noise is reduced by adding capacitor to the output, but the value should be limited to 1nF or less to insure stability. Board Assembly Considerations FGA references provide high accuracy and low temperature drift but some PC board assembly precautions are necessary. Normal Output voltage shifts of 100μV to 1mV can be expected with Pbfree reflow profiles or wave solder on multi-layer FR4 PC boards. Precautions should be taken to avoid excessive heat or extended exposure to high reflow or wave solder temperatures, this may reduce device initial accuracy. Post-assembly x-ray inspection may also lead to permanent changes in device output voltage and should be minimized or avoided. If x-ray inspection is required, it is advisable to monitor the reference output voltage to verify excessive shift has not occurred. If large amounts of shift are observed, it is best to add an X-ray shield consisting of thin zinc (300μm) sheeting to allow clear imaging, yet block x-ray energy that affects the FGA reference. Temperature Drift The limits stated for output accuracy over-temperature are governed by the method of measurement. For the -40°C to 85°C temperature range, measurements are made at +25°C and the two extremes. This measurement method combined with the fact that FGA references have a fairly linear temperature drift characteristic insures that the limits stated will not be exceeded over the temperature range. Special Applications Considerations In addition to post-assembly examination, there are also other Xray sources that may affect the FGA reference long term accuracy. Airport screening machines contain X-rays and will have a cumulative effect on the voltage reference output accuracy. Carry-on luggage screening uses low level X-rays and is not a major source of output voltage shift, however, if a product is expected to pass through that type of screening over 100 times, it may need to consider shielding with copper or aluminum. Checked luggage X-rays are higher intensity and can cause output voltage shift in much fewer passes, thus devices expected to go through those machines should definitely consider shielding. Note that just two layers of 1/2 ounce copper planes will reduce the received dose by over 90%. The leadframe for the device which is on the bottom also provides similar shielding. ISL21070 Used as a Low Cost Precision Current Source Using an N-JET and the ISL21070, a precision, low cost, high impedance current source can be created. The precision of the current source is largely dependent on the tempco and accuracy of the reference. The current setting resistor contributes less than 20% of the error. +8V TO 28V ISET = VOUT RSET IL = ISET + IRSET VIN 0.01μF VOUT ZOUT > 100MΩ RSET 1kΩ 0.1% 10ppm/°C ISL21070-2.5 VOUT = 2.5V GND ISY ~ 11μA ISET IL AT 0.1% ACCURACY ~2.5011mA FIGURE 17.
