REF3212
- Excellent specified drift performance:
- 7ppm/°C (maximum) at 0°C to +125°C
- 20ppm/°C (maximum) at –40°C to +125°C
- Microsize Package: SOT23-6
- High output current: ±10mA
- High accuracy: 0.01%
- Low quiescent current: 110µA
- Low dropout: 5mV
The REF32xx is a low drift, micropower, low-dropout, precision voltage reference family available in the SOT23-6 package.
The small size and low power consumption (130µA maximum) of the REF32xx makes the device an excellent choice for portable and battery-powered applications. This reference is stable with any capacitive load.
The REF32xx can be operated from a supply as low as 5mV above the output voltage, under no load conditions. All models are specified for the wide temperature range from –40°C to +125°C.

TIDA-00753 — 使用比流器進行三相 AC 電流量測參考設計
TIDA-00753 參考設計展示了使用 INA199 零漂移分流監測器實現三相馬達高精度、寬範圍 AC 電流測量的解決方案。此設計在增益級設定為 200 時，功耗僅 25mW，相較於分立式解決方案可顯著降低功耗。由於 INA199 內建高精度電阻，此設計的佈局面積與 BOM 成本相較分立式解決方案大幅降低。
