Dual Operational Amplifier and Voltage Reference
LM103AQ8
Description
The LM103AQ8 is a monolithic integrated circuit that includes one independent op-amp and another
op-amp, for which the non-inverting input is wired to a 2.5V fixed voltage reference. This device is
offering space and cost saving in many applications like power supply management or data acquisition
systems.
Features
• Low input offset voltage : 0.5mV(typ.)
• Low supply current : 350μA/op (@VCC=5V)
• Medium bandwidth (unity gain) : 0.9MHz
• Large output voltage swing : 0V to VCC-1.5V
• Input common mode voltage range includes ground
• Wide power supply range : 3 to 32V
• Fixed output voltage reference, 2.5V
• 0.4% and 1% voltage precision
• Sink current capability : 1 ~ 100mA
• Typical output impedance : 0.2Ω
• Pb-free package
Applications
• Battery charger
• Switch mode power supply
• Linear regulator

Note : The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V. The upper
end of the common-mode voltage range is (VCC+)-1.5V. But either of both inputs can go to +36V without damage.
