RS103
Dual Operational Amplifier and
Voltage Reference
8-Lead Plastic
DIP-8
Package Code: P
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.

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.
