AD1582/AD1583/AD1584/AD1585 are 2.5 V to 5.0 V micropower, precision series mode voltage references from Analog Devices. They feature low quiescent current, high output current, wide supply range, low noise and small package.
The AD1582, AD1583, AD1584, and AD1585 are a family of low‑cost, low‑power, low‑dropout precision band‑gap references packaged in a compact SOT‑23 surface‑mount package. They are designed for battery‑powered 3 V or 5 V systems and provide stable output with minimal power dissipation.
Key features include a wide supply range (200 mV headroom to 12 V), low quiescent current (70 µA max), up to 5 mA source/sink capability, and tight temperature stability across –40 °C to +125 °C. Detailed specifications for each voltage version (2.5 V, 3 V, 4.096 V, 5 V) are provided, along with ordering information and absolute maximum ratings.
