Both devices are fabricated in a new precision 40V complementary bipolar DI process. A superbeta NPN input stage with input bias current cancellation provides low input bias current (1nA typical), low input offset voltage (10µV typ), low input noise voltage (3nV/√Hz), and low 1/f noise corner frequency (5Hz). These amplifiers also feature high open loop gain (1500V/mV) for excellent CMRR (120dB) and THD+N performance (0.0002% @ 3.5VRMS, 1kHz into 2kΩ). 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). Parameter variation with operating voltage is shown in the “Typical Performance Curves” beginning on page 8. Input ESD Diode Protection The input terminals (IN+ and IN-) have internal ESD protection diodes to the positive and negative supply rails, and an additional anti-parallel diode pair across the inputs (see Figures 38 and 39). V+ VIN RIN VOUT + RL V- FIGURE 38. INPUT ESD DIODE CURRENT LIMITING- UNITY GAIN For unity gain applications (see Figure 38) where the output is connected directly to the non-inverting input a current limiting resistor (RIN) will be needed under the following conditions to protect the anti-parallel differential input protection diodes. • The amplifier input is supplied from a low impedance source. • The input voltage rate-of-rise (dV/dt) exceeds the maximum slew rate of the amplifier (±3.6V/µs). If the output lags far enough behind the input, the anti-parallel input diodes can conduct. For example, if an input pulse ramps from 0V to +10V in 1µs, then the output of the ISL28x27 will reach only +3.6V (slew rate = 3.6V/µs) while the input is at 10V, The input differential voltage of 6.4V will force input ESD diodes to conduct, dumping the input current directly into the output stage and the load. The resulting current flow can cause permanent damage to the ESD diodes. The ESD diodes are rated to 20mA, and in the previous example, setting RIN to 1k resistor (see Figure 38) would limit the current to < 6.4mA, and provide additional protection up to ±20V at the input. In applications where one or both amplifier input terminals are at risk of exposure to high voltage, current limiting resistors may be needed at each input terminal (see Figure 39 RIN+, RIN-) to limit current through the power supply ESD diodes to 20mA. 14 VINVIN+ RIN- - RIN+ + VOUT RL V- FIGURE 39. INPUT ESD DIODE CURRENT LIMITING DIFFERENTIAL INPUT Output Current Limiting The output current is internally limited to approximately ±45mA at +25°C and can withstand an 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 ISL28127 and ISL28227 are immune to output phase reversal, even when the input voltage is 1V beyond the supplies. Power Dissipation It is possible to exceed the +150°C maximum junction temperatures under certain load and power supply conditions. It is therefore important to calculate the maximum junction temperature (TJMAX) 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: (EQ. 1) T JMAX = T MAX + θ JA xPD MAXTOTAL where: • PDMAXTOTAL is the sum of the maximum power dissipation of each amplifier in the package (PDMAX) • PDMAX for each amplifier can be calculated using Equation 2: V OUTMAX PD MAX = V S × I qMAX + ( V S - V OUTMAX ) × -----------------------R (EQ. 2) L where: • TMAX = Maximum ambient temperature • θJA = Thermal resistance of the package • PDMAX = Maximum power dissipation of 1 amplifier • VS = Total supply voltage • IqMAX = Maximum quiescent supply current of 1 amplifier • VOUTMAX = Maximum output voltage swing of the application RL = Load resistance FN6633.6 December 16, 2010 ISL28127, ISL28227 ISL28127 and ISL28227 SPICE Model LICENSE STATEMENT Figure 40 shows the SPICE model schematic and Figure 41 shows the net list for the ISL28127 and ISL28227 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 parameters are VOS, IOS, total supply current and output voltage swing. The model does not model input bias current. The model uses typical parameters given in the “Electrical Specifications” Table beginning on page 4. The AVOL is adjusted for 128dB with the dominate pole at 5Hz. The CMRR is set higher than the “Electrical Specifications” Table to better match design simulations (150dB, f = 50Hz). The input stage models the actual device to present an accurate AC representation. The model is configured for ambient temperature of +25°C.
