DESCRIPTION
The
µPC311 is a voltage comparator that has input currents more than a hundred times lower than devices like
conventional standard type of 710. It is also designed to operate over a wide range of supply voltages; from
±15 V op
amp supplies down to the single 5 V supply used for IC logic. Its output is compatible with HNIL, DTL and TTL as well
as MOS circuits.
FEATURES
• Operate from single 5 V supply
• Maximum input current: 250 nA
• Maximum offset current: 50 nA
• Fast transient response: 200 ns TYP.
