Product details

Precision 2.048 V shunt reference in a SOT-23-3

The Maxim Integrated LM4050AEM3-2.1+T is a precision shunt voltage reference delivering a fixed 2.048 V output with ±0.1% initial tolerance. Housed in a SOT-23-3 package, it targets precision analog circuits — ADC references, comparator thresholds, and regulator feedback dividers — where a stable, low-drift voltage is needed across -40°C to 125°C.

What the ratings mean for your BOM

The 15 mA output current and 65 µA minimum cathode current define the bias resistor range.

Temperature grade and environment

Rated for -40°C to 125°C operation, this part covers industrial control cabinets, outdoor telecom gear, and under-hood automotive modules.

Sourcing and lifecycle

ROHS3 compliant.
