RS103
Dual Operational Amplifier and
Voltage Reference
Description
The RS103 is a monolithic IC 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.
Operational Amplifier
• Low input offset voltage: 0.5mV typ.
• Low supply current: 350mA/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 ±1.5 to ±16V
Operational Amplifier
• Fixed output voltage reference 2.5V
• 0.5% and 1% voltage precision
• Sink current capability: 1 to 100mA
• Typical output impedance: 0.2Ω

1. 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.
