15 fn6632.2 october 16, 2009 applications information functional description the isl28117 and ISL28217 are single and dual, low noise precision op amps. both devices are fabricated in a new precision 40v complementary bipolar di process. a super-beta npn input stage with input bias current cancellation provides low input bias current (180pa typical), low input offset voltage (13v typical), low input noise voltage (8nv / hz), and low 1/f noise corner frequency (~8hz). these ampl ifiers also feature high open loop gain (18kv/mv) for excellent cmrr (145db) and thd+n performance (0.0005% @ 3.5v rms , 1khz into 2k ). a complimentary bipolar output stage enables high capacitive load drive without external compensation. 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). the power supply rejection ratio typically exceeds 140db over the full operating voltage range and 120db minimum over the -40c to +125c temperature range. the worst case common mode input voltage range over temperature is 2v to each rail. with 15v supplies, cmrr performance is typically >130db over -temperature. the minimum cmrr performance over the -40c to +125c temperature range is >120db for power supply voltages from 5v (10v) to 15v (30v). input performance the super-beta npn input pair provides excellent frequency response while maintaining high input precision. high npn beta (>1000) reduces input bias current while maintaining g ood frequency response, low input bias current and low noise. input bias cancellation circuits provide additional bias current reduction to <1na, and excellent temperature stabilization. figures 9 through 16 show the high degree of bias current stability at 5v and 15v supplies that is maintained across the -40c to +125c temperature range. the low bias current tc also produces very low input offset current tc, which reduces dc input offset errors in precision, high impedance amplifiers. the +25c maximum input offset voltage (v os ) for the ?b? grade is 50v and 100v for the ?c? grade. input offset voltage temper ature coefficients (v os tc) are a maximum of 0.6v/c for the ?b? and 0.9v/c for the ?c? grade. figures 1 through 4 show the typical gaussian- like distribution over the 5v to 15v supply range and over the full temperature range. the v os temperature behavior is smooth (figures 5 through 8) maintaining constant tc across the entire temperature range. input esd diode protection the input terminals (in+ and in-) have internal esd protection diodes to the po sitive and negative supply rails, series connected 500 current limiting resistors and an anti-parallel diode pair across the inputs (figure 51). the series resistors limit the high feed-through currents that can occur in pulse applications when the input dv/dt exceeds the 0.5v/s slew rate of the amplifier. without the series resistors, the input can forward-bias the anti-parallel diodes causing current to flow to the output resulting in severe distortion and possible diode failure. figure 46 provides an example of distortion free large signal response using a 4v p-p input pulse with an input rise time of <1ns. the series resistors enable the input differential voltage to be equal to the maximum power supply voltage (40v) without damage. in applications where one or both amplifier input terminals are at risk of exposure to high voltages beyond the power supply rails, current limiting resistors may be needed at the input terminal to limit the current through the power supply esd diodes to 20ma max. output current limiting the output current is internally limited to approximately 45ma 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 1 amplifier at a time for the dual op amp. continuous operation under these conditions may degrade long term reliability. figures 25 and 26 show the current limit variation with temperature. 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 isl28117 and ISL28217 are immune to output phase reversal, even when the input voltage is 1v beyond the supplies. power dissipation it is possible to exceed the +150c maximum junction temperatures under certain load and power supply conditions. it is therefore important to calculate 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: figure 51. input esd diode current limiting- unity gain - + r l v in v out v+ v- 500 500 t jmax t max ja xpd maxtotal + = (eq. 1) isl28117, ISL28217
