isl28107, isl28207, isl28407 19 fn6631.5 october 21, 2011 applications information functional description the isl28107, isl28207 and is l28407 are single, dual and quad, very low 1/f noise (14nv/ hz @ 10hz) precision op-amps. these amplifiers feature very high open loop gain (50kv/mv) for excellent cmrr (145db) and gain accuracy. both devices are fabricated in a new precision 40v complementary bipolar di process. the super-beta npn input stage with bias current cancellation provides bipolar-like levels of ac performance, with the low input bias currents approaching jfet levels. the temperature stabilization provided by bias current cancellation removes the high input bias current temper ature coefficient commonly found in jfet amplifiers. figures 9 and 10 show the input bias current variation over temperature. the input offset voltage (v os ) has a very low, worst case value of 75v max at +25c and a maximum t c of 0.65v/c. figure 38 shows v os as a function of supply voltage and temp erature with the common mode voltage at 0v for split supply operation. the complementary bipolar outp ut stage maintains stability driving large capacitive loads (to 10nf) without external compensation. the small signal ov ershoot vs. load capacitance is shown in figure 54. operating voltage range the devices are designed to operate over the 4.5v (2.25v) to 40v (20v) range and are fully characterized at 10v (5v) and 30v (15v). both dc and ac performance remain virtually unchanged over the complete 4.5v to 40v operating voltage range. parameter variation with op erating voltage is shown in the ?typical performance curves? be ginning on page 11. the input common mode voltage range sensitivity to temperature is shown in figure 38 (15v). input esd diode protection the input terminals (in+ and in-) each have internal esd protection diodes to the positive and negative supply rails, a series connected 500 current limiting resistor followed by an anti-parallel diode pair across th e input npn transistors (circuit 1 in ?pin descriptions? on page 3). figure 51. small signal transient response v s = 5v, 15v, 20v figure 52. positive output overload response time, v s =15v figure 53. negative output overload response time, v s = 15v figure 54. % overshoot vs load capacitance, v s = 15v typical performance curves v s = 15v, v cm = 0v, r l = open, t a = +25c unless otherwise specified.

isl28107, isl28207, isl28407 20 fn6631.5 october 21, 2011 the resistor-esd diode configurat ion enables a wide differential input voltage range equal to the lesser of the maximum supply voltage in the ?absolute maximum ratings? on page 6 (42v), or a maximum of 0.5v beyond the v+ and v- supply voltage. the internal protection resistors eliminate the need for external input current limiting resistors in unity gain connections and other circuit applications where large volt ages or high slew rate signals are present. although the amplifie r is fully protected, high input slew rates that exceed the amplifier slew rate (0.32v/s) may cause output distortion. output current limiting the output current is internally limited to approximately 40ma at +25c and can withstand a short circuit to either rail as long as the power dissipation limits are not exceeded. this applies to only one amplifier at a time fo r the dual op-amp. continuous operation under these condit ions may degrade long-term reliability. output phase reversal output phase reversal is a change of polarity in the amplifier transfer function when the input voltage exceeds the supply voltage. the isl28107, isl2820 7 and isl28407 are immune to output phase reversal, even when the input voltage is 1v beyond the supplies. unused channels if the application only requires one channel, the user must configure the unused channels to prevent them from oscillating. the unused channels can oscillate if the input and output pins are floating. this results in high er than expected supply currents and possible noise injection into the channel being used. the proper way to prevent this oscillation is to short the output to the inverting input and ground the positive input, as shown in figure 55. power dissipation it is possible to exceed the +150c maximum junction temperatures under certain load and power supply conditions. it is therefore important to ca lculate the maximum junction temperature (t jmax ) for all applications to determine if power supply voltages, load conditions , or package type need to be modified to remain in the safe operating area. these parameters are related using equation 1: where: ?p dmaxtotal is the sum of the maximum power dissipation of each amplifier in the package (pd max ) pd max for each amplifier can be calculated using equation 2: where: ?t max = maximum ambient temperature ? ja = thermal resistance of the package ?pd max = maximum power dissipation of one amplifier ?v s = total supply voltage ?i qmax = maximum quiescent supply current of one amplifier ?v outmax = maximum output voltage swing of the application ?r l = load resistance isl28107, isl28207, isl28407 spice model figure 56 shows the spice model schematic, and figure 57 shows the net list for the isl28107, isl28207 and isl28407 spice model. the model is a simplified version of the actual device and simulates important ac and dc parameters. ac parameters incorporated into the model are: 1/f and flatband noise, slew rate, cmrr, gain and phase. the dc pa rameters are vos, ios, total supply current and output voltage swing. the model uses typical parameters given in the ?electrical specifications? table beginning on page 6. a vol is adjusted for 155db with the dominant pole at 0.01hz. cmrr is set (145db, f cm = 100hz). the input stage models the actual devi ce to present an accurate ac representation. the model is conf igured for ambient temperature of +25c. figures 58 through 68 show the characterization vs simulation results for the noise voltage, closed loop gain vs frequency, closed loop gain vs r l , large signal step response, open loop gain phase and simulated cmrr vs frequency. license statement the information in this spice model is protected under the united states copyright laws. intersil corporation hereby grants users of this macro-model hereto referred to as ?licensee?, a nonexclusive, nontransferable licence to use this model as long as the licensee abides by the terms of this agreement. before using this macro-model, the licensee should read this license. if the licensee does not accept these terms, permission to use the model is not granted. the licensee may not sell, loan, re nt, or license the macro-model, in whole, in part, or in modified form, to anyone outside the licensee?s company. the licensee may modify the macro-model to suit his/her specific applications, and the licensee may make copies of this macro-model for use within their company only. this macro-model is provided ?as is, where is, and with no warranty of any kind either expressed or implied, including buy not limited to any implied warranties of merchantability and fitness for a particular purpose.?
