Product details

1.225 V fixed shunt reference in SC-70-5

The LM4041EIM7-1.2 from Texas Instruments is a precision shunt voltage reference delivering a fixed 1.225 V output with ±2% initial tolerance.

12 mA output, 65 µA cathode current — load-driving limits

Output current is rated at 12 mA, which sets the ceiling for driving multiple loads or feeding an ADC reference input. The minimum cathode current is 65 µA — below this the reference may drop out of regulation, so the series resistor must be sized to keep at least 65 µA flowing into the cathode at all load conditions. The temperature coefficient is 150 ppm/°C, and wideband noise from 10 Hz to 10 kHz is specified at 20 µVrms. For a 1.225 V reference, this noise floor is low enough for 12-bit ADC applications without additional filtering.

The LM4041EIM7-1.2 is listed as Obsolete. Texas Instruments has discontinued this specific grade/package variant.

Frequently asked questions

Is the LM4041EIM7-1.2 obsolete?

Yes, the LM4041EIM7-1.2 is listed as Obsolete. Texas Instruments has discontinued this specific variant. Buyers should plan for a replacement or secure remaining surplus inventory.

Can I use LM4041AIM7-1.2 as a replacement for LM4041EIM7-1.2?

The LM4041AIM7-1.2 is a higher-grade variant of the same base part number (LM4041) in the same SC-70-5 package with the same 1.225 V fixed output. It typically offers tighter tolerance (±0.1% or ±0.5%) and a wider temperature range, making it a pin-compatible, performance-superior drop-in replacement. However, confirm the specific tolerance and temperature grade on the LM4041AIM7-1.2 datasheet to ensure it meets your application requirements.
