isl28118, isl28218 18 fn7532.1 november 22, 2010 applications information functional description the isl28118 and isl28218 are single and dual, single supply rail-to-rail output amplifiers with a common mode input voltage range extending to 0.5v below the v- rail. these op amps feature very low quiescent current of 850v, and low temperature drift. both devices are fabricated in a new precision 40v complementary bipolar di process and immune from latch-up. operating voltage range the devices are designed to operate over the 3v (1.5v) to 40v (20v) range and are characterized at 10v (5v) and 30v (15v). both dc and ac performance remain virtually unchanged over the complete operating voltage range. parameter variation with operating voltage is shown in the ?typical performance curves? beginning on page 7. input stage performance the isl28118 and isl28218 pn p input stage provides a maximum input differential voltage of 42v. the input stage is capable of below gro und sensing. the device is fully characterized down to half a volt below the v- rail at +25c. the input common mode voltage range sensitivity to temperature is shown in figure 10 (15v). these features provide excellent cmrr, ac performance and extremely low input distortion over a wide temperature range. input esd diode protection the pnp input stage has a max input differential voltage equal to a diode drop greater than the supply voltage (max 42v). this feature enables the device to function reliably in large signal pulse applications without the need for anti-parallel clamp diodes required on mosfet and most bipolar input stage op amps. thus, input signal distortion caused by nonlinear clamps under high slew rate conditions are avoided. in applications where one or both amplifier input terminals are at risk of exposure to voltages beyond the supply rails, current limiting resistors may be needed at each input terminal (see figure 62 r in +, r in -) to limit current through the power supply esd diodes to 20ma. output drive capability the bipolar rail-to-rail output stage features rail-to-rail output swing at moderate levels of output current (figures 31 through 34). the output current is internally limited. output current limit over-temperature is shown in figures 31 through 34. the amplifiers can withstand a short circuit to either rail as long as the power dissipation limits are not exceeded. this applies to only 1 amplifier at a time for the dual op amp. continuous operation under these conditions 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 isl28118 and isl28218 are immune to output phase reversal, out to 0.5v beyond the rail (v abs max ) limit (figure 49). using only one channel the isl28218 is a dual op-amp. if the application only requires one channel, the user must configure the unused channel to prevent it from oscillating. the unused channel will oscillate if the input and output pins are floating. this will result in higher 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 63). figure 62. input esd diode current limiting - + r in - r l v in - v+ v- r in + v in + figure 63. preventing oscillations in unused channels - +
