Product details

The ISL21080CIH320Z-TK: RoHS3 compliant per the manufacturer's declaration, so no regulatory barrier for EU or global BOMs.

2.048 V reference with 1.5 µA supply current

Fixed 2.048 V output with ±0.3% initial accuracy — a common ADC reference voltage that also serves as a precision bias for DACs or sensor front-ends. Supply current is just 1.5 µA, making this reference suitable for battery-powered instrumentation where every microamp matters. Output current capability is 7 mA, enough to drive the reference input of most SAR ADCs or a small resistive load without an external buffer.

SOT-23-3 package and board integration

Housed in the SOT-23-3 (TO-236-3 / SC-59) surface-mount package, the part occupies minimal PCB area and routes easily in dense analog or mixed-signal layouts.
