10 / 14 page 10 FN6152.3 November 5, 2007 Pin Descriptions Applications Information Introduction The ISL28196 and ISL28197 are CMOS rail-to-rail input and output (RRIO) micropower comparators. These devices are designed to operate from single supply (1.8V to 5.5V) and have an input common mode range that extends to the positive rail and to the negative supply rail for true rail-to-rail performance. The CMOS output can swing within tens of millivolts to the rails. Featuring worst case maximum supply currents of only 4.5µA and 2µA for the ISL28196 and ISL28197 respectively, these comparators are ideally suited for solar and battery powered applications. Input 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. Both the ISL28196 and ISL28197 have a maximum input differential voltage that extends beyond the rails (+V + 0.5V to -V - 0.5V). Rail-to-Rail Output A pair of complementary MOSFET devices are used to achieve the rail-to-rail output swing. The NMOS sinks current to swing the output in the negative direction. The PMOS sources current to swing the output in the positive direction. The ISL28196 and ISL28197 with a 100k Ω load will swing to within 6mV of the positive supply rail and within 3mV of ground.
