KA311 SINGLE COMPARATOR
8 DIP
VOLTAGE CO MPARATOR
The KA311 series is a monolithic, low input current voltage
comparator. This device is also designed to operate from
dual or single supply voltage.
FEATURE
• Low input bias current : 250nA (Max) 8 SOP
• Low input offset current : 50nA (Max)
• Differential Input Voltage :
30V.
• Power supply voltage : single 5.0V supply to
15V.
• Offset voltage null capability.
• Strobe capability.
