Features, Applications


The RH119 dual comparator features low input offset voltage and offset current, high voltage gain, guaranteed common mode rejection and input protection diodes. The RH119 is capable of operation over a supply range from to 15V and can drive 25mV leads from each open collector output. A separate GND pin allows the RH119 to isolate system grounds. The wafer lots are processed to Linear Technology's inhouse Class S flow to yield circuits usable in stringent military applications.

Note 3: The offset voltages and currents given are the maximum values required to drive the output within 1V of either supply with a 1mA load thus, these parameters define an error band and take into account the worst-case effects of voltage gain and input impedance. Note 4: Response time specified for a 100mV input step with 5mV overdrive. Note 15V, VCM = 25C unless otherwise noted. Note 1: For supply voltages less than 15V, the maximum input voltage is equal to the supply voltage. Note 2: Unless otherwise noted, supply voltage equals 15V and = 25C. The GND pin is grounded. Note that the maximum voltage allowed between the GND pin and 18V. Do not tie the GND pin V when the power supply voltage exceeds 9V. The offset voltage, offset current and bias current specifications apply for all supply voltages between 15V and 5V unless otherwise specified.
