DESCRIPTION
The TSM103W 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 offers both space and cost savings in many applications such as power supply management or data acquisition systems.
