![]() ![]() The LM339B and LM2901B can drop-in replace the LM239, LM339 and LM2901, for both "A" and "V" grades.Īll devices consist of four independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. These next generation B-version comparators feature lower offset voltage, higher supply voltage capability, lower supply current, lower input bias current, lower propagation delay, and improved 2 kV ESD performance and input ruggedness through dedicated ESD clamps. The LM339B and LM2901B devices are the next generation versions of the industry-standard LM339 and LM2901 comparator family. For dual version, see the LM393B or LM2903B.Output compatible with TTL, MOS, and CMOS.The LM339 has open-collector outputs which. It can be used with Single or Dual power supplies from 2v to 36v. We set the trigger level by Zener Diode (IN5233) of 6 volts in the inverting terminal of IC. The LM339 operates with a single power supply over a wide range of voltages and has a very low offset voltage of 2 millivolts. The battery discharges are simulated with a potentiometer 5k. Differential input voltage range equal to maximum-rated supply voltage: ☓8 V This kit is centered around the very popular LM339 Quad, Precision Voltage Comparator in a 14-pin DIP package.Common-mode input voltage range includes ground.B-version is drop-in replacement for LM239, LM339 and LM2901, A and V versions.Low supply-current: 200 ♚ per comparator.
