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. It features low temperature coefficient, low operating current, and wide operating current range.
The SPX1004 is a bandgap precision voltage reference that provides a stable fixed output of 1.2 V or 2.5 V with tight initial voltage tolerances (+10 mV for 1.2 V, +20 mV for 2.5 V). It features a low dynamic impedance of 0.6 Ω max, very low operating current, and a temperature coefficient of 25 ppm/°C. The device is offered in SOT‑89, NSOIC‑8 and TO‑92 packages and operates from 0 °C to 70 °C.
Typical applications include use as a reference for A/D and D/A converters, power‑supply monitoring, and as a direct pin‑to‑pin replacement for LT1004, LM1004 or AS1004. Ordering information, pin‑outs, and detailed electrical characteristics are provided in the later sections of the document.
