They are designed to operate from single supply (1.8V to 5.5V) or dual supply (±0.9V to ±2.75V). The parts have an input common mode range that extends 100mV above and below the power supply voltage rails. The output stage can swing to within 15mV of the supply rails with a 10kΩ load. Power Dissipation It is possible to exceed the +125°C maximum junction temperatures under certain load, power supply conditions and ambient temperature 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: T JMAX = T MAX + θ JA xPD MAXTOTAL (EQ. 1) Input ESD Diode Protection All input terminals have internal ESD protection diodes to both positive and negative supply rails, limiting the input voltage to within one diode beyond the supply rails. They also contain back-to-back diodes across the input terminals (see “Pin Descriptions - Circuit 1” on page 3). For applications where the input differential voltage is expected to exceed 0.5V, an external series resistor must be used to ensure the input currents never exceed 20mA (see Figure 18). 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 L (EQ. 2) where: • TMAX = Maximum ambient temperature VIN RIN + RL VOUT • 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 FIGURE 18. INPUT CURRENT LIMITING Although the amplifier is fully protected, high input slew rates that exceed the amplifier slew rate (±1V/µs) may cause output distortion. 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 ISL28113, ISL28213 and ISL28413 are immune to output phase reversal, even when the input voltage is 1V beyond the supplies. ISL28113, ISL28213 and ISL28413 SPICE Model Figure 20 shows the SPICE model schematic and Figure 21 shows the net list for the 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 IOS, total supply current and output voltage swing. The model uses typical parameters given in the “Electrical Specifications” Table beginning on page 4. The AVOL is adjusted for 85dB with the dominate pole at 100Hz. The CMRR is set 72dB, f = 35kHz). The input stage models the actual device to present an accurate AC representation. The model is configured for ambient temperature of +25°C. Figures 22 through 31 show the characterization vs simulation results for the Noise Voltage, Closed Loop Gain vs Frequency, Large Signal 5V Step Response, CMRR and Open Loop Gain Phase. Unused Channels If the application requires less than all amplifiers one channel, the user must configure the unused channel(s) to prevent it from oscillating. The unused channel(s) 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 19). + FIGURE 19.
