Dual Voltage Comparator LM393 Description:
LM393 is a dual comparator circuit, consisting of two independent and precise voltage comparators with a maximum offset voltage of no more than 2.0mV. These comparators are specifically designed to operate under a wide voltage range with a single power supply, but they can also function with dual power supplies, and their power current is unaffected by the amplitude of the power supply voltage. A unique feature of these comparators is that, even when operating with a single power supply, their input common-mode voltage range remains at zero. Key features include::
Wide voltage range for power supply: Single power supply:2.0 ~ 36V, dual power supply:±1.0V ~±18V
Low input bias current:25mA
Low-input失调current:±5mA
Maximum voltage deviation:3mV
Input common mode voltage range can reach 0 V
Input differential voltage range equals power supply voltage
Output voltage is compatible with TTL, DTL, ECL, MOS, and CMOS logic systems.
Packaging Type:DIP8/SOP8
