The SPX1004 is a 2-terminal bandgap precision voltage reference that provides a stable fixed output voltage of 1.2V and 2.5V with a tolerance of ±10mV for SPX1004-1.2 and ±20mV for SPX1004-2.5. Design, process and precision on chip trimming yield a very low tempera- ture coefficient of 25 ppm/°C.
The SPX1004 is a bandgap precision voltage reference that provides fixed 1.2 V and 2.5 V outputs with tight initial voltage tolerances (+10 mV for 1.2 V, +20 mV for 2.5 V) and a low dynamic impedance of 0.6 Ω max. It operates from 0 °C to 70 °C and draws as little as 10 µA (1.2 V) or 20 µA (2.5 V).
The device is offered in SOT‑89, NSOIC‑8 and TO‑92 packages and can be used as a pin‑to‑pin replacement for the LT1004, LM1004 or AS1004. Application circuits include low‑noise references, high‑stability regulators and battery‑monitoring circuits. Ordering information and part numbers for each package and tolerance option are provided.
