32 fn8082.13 december 17, 2007 applications information fga technology the isl60002 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 e xcellent characte ristics which are unique in the industry: very low temperature drift, high initial accuracy, and almost zero suppl y 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 am plifier 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 limita tions are addressed with circuit techniques discussed in other sections. nanopower operation reference devices achieve their highest accuracy when powered up continuously, and after initial stabilization has taken place. this drift can be eliminated by leaving the power on continuously. the isl60002 is the first high precision voltage reference with ultra low power consumption that makes it possible to leave power on continuously in battery operated circuits. the isl60002 consumes extremely lo w supply current due to the proprietary fga technology. supply current at room temperature is typically 350na, which is 1 to 2 orders of magnitude lower than compet itive devices. 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 disabled when not in use can remain powered up between conversions as shown in figure 116. data acquisition circuits providing 12 to 24 bits of accuracy can operate with the reference device continuously biased with no power penalty, providing the highest accuracy and lowest possible long term drift. other reference devices consuming higher supply currents will need to be disabled in betw een conversions to conserve battery capacity. absolute accuracy will suffer as the device is biased and requires time to settle to its final value, or, may not actually settle to a final value as power on time may be short. 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. high current application figure 114. different v in at room temperature figure 115. different v in at high temperature 2.486 2.488 2.490 2.492 2.494 2.496 2.498 2.500 2.502 0 5 10 15 20 25 30 i load (ma) v out (v) v in = 3.3v v in = 3.5v v in = 5v 2.4980 2.4983 2.4986 2.4989 2.4992 2.4995 2.4998 2.5001 0 4 8 12 16 20 24 28 32 i load (ma) v out (v) normalized to 0ma load 3.3v in , +85c 5v in , +85c 3.2v in , +85c v in = +3.0v 0.001f to 0.01f serial bus v in v out gnd isl60002-25 ref in enable sck sdat a/d converter 12 to 24-bit 0.01f 10f figure 116. vout = 2.5v isl60002
33 fn8082.13 december 17, 2007 noise performance and reduction the output noise voltage in a 0.1hz to 10hz bandwidth is typically 30v p-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 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. noise in the 10khz to 1mhz bandwidth is approximately 400v p-p with no capacitance on the output, as shown in figure 117. 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 freque ncy. figure 117 also shows the noise in the 10khz to 1mhz band can be reduced to about 50v p-p using a 0.001f capacitor on the output. noise in the 1khz to 100khz band can be further reduced using a 0.1f capacitor on the output, but noise in the 1hz to 100hz band increases due to instability of the very low power amplifier with a 0.1f capacitance load. for load capacitances above 0.001f the noise reduction network shown in figure 118 is recommended. this network reduces noise significantly over the full bandwidth. as shown in figure 117, noise is reduced to less than 40v p-p from 1hz to 1mhz using this network with a 0.01f capacitor and a 2k resistor in series with a 10f capacitor. turn-on time the isl60002 devices have ultra-low supply current and thus the time to bias up internal circuitry to final values will be longer than with higher power references. normal turn-on time is typically 7ms. this is shown in figure 119. since devices can vary in supply current down to >300na, turn-on time can last up to about 12ms. care should be taken in system design to include this delay before measurements or conversions are started. temperature coefficient the limits stated for temperature coefficient (tempco) are governed by the method of measurement. the overwhelming standard for specifying the temperature drift of a reference is to measure the reference voltage at two temperatures, take the total variation, (v high ? v low ), and divide by the temperature extremes of measurement (t high ?t low ). the result is divided by the nominal reference voltage (at t = +25c) and multiplied by 10 6 to yield ppm/c. this is the ?box? method for specifying temperature coefficient. cl = 0 cl = 0.001f cl = 0.1f cl = 0.01f and 10f + 2k 400 350 300 250 200 150 100 50 0 1 10 100 1k 10k 100k noise voltage (v p-p ) figure 117. noise reduction v in = 3.0v v in v o gnd isl60002-25 0.01f 10f 2k 0.1f 10f figure 118. vout = 2.50v figure 119. turn-on time v in 3.0 2.5 2.0 1.5 1.0 0.5 0 v in and v out (v) -11357911 time (ms) unit 3 unit 1 unit 2 3.5 v in 3.0 2.5 2.0 1.5 1.0 0.5 0 v in and v out (v) -11357911 time (ms) unit 3 unit 1 unit 2 3.5 isl60002
