Product details

Precision shunt reference for 4.096 V rails

The LM4050AIM3-4.1+T: This combination makes it a stable, low-drift voltage reference for precision analog circuits such as ADCs, DACs, and sensor signal chains where the 4.096 V rail aligns with common full-scale input ranges.

Parametric fit for analog signal chains

The 4.096 V output is a standard reference voltage for many 12- and 16-bit ADCs with a 4.096 V full-scale input; the ±0.1% tolerance keeps the gain error contribution below 1 LSB for a 12-bit converter. As a shunt reference, it sinks current from the load rather than sourcing it — the 73 µA minimum cathode current sets the floor for the series resistor calculation, while the 15 mA maximum output current defines the ceiling for the load plus the reference's own draw.

SOT-23-3 footprint and industrial temperature grade

Housed in a standard SOT-23-3 package (TO-236-3, SC-59 alternative), the LM4050AIM3-4.1+T occupies minimal board area and is compatible with common three-pin shunt reference layouts.

Frequently asked questions

Can LM4050AIM3-4.1+T replace LM4040AIM3-4.1 in an existing design?

The LM4050AIM3-4.1+T is a higher-precision sibling of the LM4040AIM3-4.1. Both are 4.096 V shunt references in the same SOT-23-3 package, but the LM4050AIM3-4.1+T offers ±0.1% tolerance versus the LM4040's typical ±0.5% grade. Pin-compatible for a drop-in upgrade where tighter initial accuracy is needed.

Is LM4050AIM3-4.1+T RoHS compliant?

The LM4050AIM3-4.1+T is listed as RoHS compliant per Analog Devices' standard lead-free plating for the SOT-23-3 package. The 'T' suffix in the order code typically indicates tape-and-reel packaging, which is fully RoHS-compatible.
