It targets precision analog circuits — ADCs, DACs, and regulator feedback dividers — where initial accuracy and thermal drift directly affect system error budgets.
Lifecycle status is Active. The part is ROHS3 compliant.
As a series reference, it requires an external output capacitor for stability. No other external components are needed for the basic reference function — the internal bandgap and output buffer are self-contained.
The temperature coefficient is 3 ppm/°C. Over the -40 to 125 °C operating range, that adds roughly 1.2 mV of voltage drift.
