The 10 mA output current is enough to drive the reference input of multiple ADCs or a small resistive divider network without an external buffer.
On a mixed-signal board, keep the reference close to the ADC reference input pin and use a dedicated low-impedance ground plane under the package to minimise noise coupling.
Determines if it fits the required reference voltage in the design.
Critical for precision applications; affects design margins.
Needed for PCB layout and compatibility with existing designs.
Sourcing buyers need to find stock and lead times.
Lifecycle status affects long-term availability and replacement planning.
Design engineers and maintenance techs need alternatives for sourcing or replacement.
