The SPX1004 is a 1.2V/2.5V micropower voltage reference that provides a stable fixed output voltage of 1.2V and 2.5V with a tolerance of ±4mV for SPX1004-1.2 and ±20mV for SPX1004-2.5.
The SPX1004 is a 2‑terminal bandgap precision voltage reference offering fixed output voltages of 1.2 V (SPX1004‑1.2) and 2.5 V (SPX1004‑2.5) with low temperature coefficient and low dynamic impedance. It is available in SOT‑89, SOIC‑8, and TO‑92 packages and operates over a temperature range of 0 °C to 70 °C.
The device can be used as a direct pin‑to‑pin replacement for LT1004, LM1004 and AS1004 and is suitable for A/D and D/A reference, power‑supply monitoring, and low‑noise reference applications. Ordering information, pin‑outs, and example application circuits are included in the datasheet.
