ISL70419SEH 17 july 11, 2014 fn8653.0 submit document feedback applications information functional description the ISL70419SEH contains four, low noise precision op amps. these devices are fabricated in a new precision 40v complementary bipolar di process. a super-beta npn input stage with input bias current cancella tion provides low input bias current (180pa typical), low inpu t offset voltage (13v typical), low input noise voltage (8nv/ ? hz), and low 1/f noise corner frequency (~8hz). these amplifiers also feature high open loop gain (14kv/mv) for excellent cmrr (145db) and thd+n performance (0.0005% at 3.5v rms , 1khz into 2k ? ). a complementary bipolar output st age enables high capacitive load drive without external compensation. operating voltage range the devices are designed to operate over the 4.5v (2.25v) to 36v (18v) voltage 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 -55c to +1 25c 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-tempe rature. the minimum cmrr performance over the -55c 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 good frequency response, low input bias current and low noise. input bias cancellation circuits pr ovide additional bias current reduction to <5na, and excellent temperature stabilization. figures 6 through 8 show the high degree of bias current stability at 5v and 15v supplies that is maintained across the -55c 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 ) is 75v at 15v supplies. input offset voltage temperature coefficients (v os tc) is a maximum of 1.0v/c. the v os temperature behavior is smooth ( figures 3 through 4 ) 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 positive and negative supply rails, series connected 500 ? current limiting resistors and an anti-parallel diode pair across the inputs ( figure 53 ). the series resistors limit the high feed-through currents that can occur in pulse applications wh en 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-par allel diodes causing current to flow to the output resulting in severe distortion and possible diode failure. figure 36 provides an example of distortion free large signal response using a 4v p-p input pulse with an in put rise time of <1ns. the series resistors enable the input differential voltage to be equal to the maximum power supply voltage (36v) 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 quad op amp. continuous operation under these conditio ns may degrade long term reliability. figures 15 and figure 16 on page 10 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 ISL70419SEH is immu ne to output phase reversal, even when the input voltage is 1v beyond the supplies. figure 53. input esd diode current limiti ng- unity gain - + r l v in v out v+ v- 500 ? 500 ?
