General Description
The MCP1501 is a buffered voltage reference capable
of sinking and sourcing 20 mA of current. The voltage
reference is a low-drift band gap based reference. The
band gap uses chopper-based amplifiers, effectively
reducing the drift to zero.
The MCP1501 is available in the following packages:
