What are the key features of LM4040DIM3X-6.0/NOPB?

  • Precision 6.0 V shunt reference with 0.1% initial accuracy and tight 5.994 V to 6.006 V output tolerance
  • Two-terminal shunt configuration requiring no separate enable or trim pins for simple resistor-programmed biasing
  • Compact 3-pin SOT-23 (TSOP) package minimizing board area in portable and handheld instrument designs
  • RoHS-compliant and REACH-compliant lead-free construction (NOPB designation) for global regulatory compliance
  • Low-noise output suitable for direct ADC reference input in 12-bit to 16-bit data-acquisition systems

What is LM4040DIM3X-6.0/NOPB used for?

The LM4040DIM3X-6.0/NOPB serves as a stable 6.0 V reference for ADC and DAC circuits in industrial data-acquisition systems, test and measurement equipment, and portable medical devices where a precise two-terminal shunt reference simplifies the supply biasing network. Its tight 0.1% accuracy and tiny SOT-23 footprint make it ideal for calibration reference nodes on multi-channel analog input cards where PCB space is at a premium. The device is also used in battery-powered instruments and signal-conditioning circuits that need a stable voltage anchor independent of load current variations.

Frequently Asked Questions

What is the output voltage accuracy of the LM4040DIM3X-6.0/NOPB and how is it specified?

The LM4040DIM3X-6.0/NOPB delivers a 6.0 V reference with a guaranteed output range of 5.994 V to 6.006 V, corresponding to a 0.1% initial accuracy specification at 25 degrees C, making it suitable for 12-bit and 14-bit ADC reference applications where tight voltage tolerance is required.

How does the two-terminal shunt topology of the LM4040DIM3X-6.0/NOPB simplify circuit design?

As a shunt reference it behaves like a precision 6.0 V zener diode: the designer connects a series resistor from the supply to set the operating current, and the device regulates its cathode-to-anode voltage to 6.0 V with no separate enable or trim pins, reducing design complexity and component count compared to a 3-terminal series reference.

Which package does the LM4040DIM3X-6.0/NOPB use and how does it affect PCB placement near ADCs?

The device is housed in a 3-pin SOT-23 package (JESD-30 code R-PDSO-G3) with a body size of approximately 2.9 mm x 1.6 mm, allowing placement within a few millimeters of ADC reference pins on a densely populated board, minimizing parasitic trace impedance and improving high-frequency noise immunity on the 6.0 V reference node.

Is the LM4040DIM3X-6.0/NOPB a suitable replacement for discrete zener diodes in precision analog designs?

Yes, it is a direct upgrade over a discrete zener: the LM4040 offers a guaranteed 0.1% initial accuracy at 6.0 V versus the typical 5% to 10% tolerance of general-purpose zeners, a lower dynamic impedance for better load regulation, and a temperature coefficient specification, making it far more predictable in ADC biasing, gain-setting, and calibration reference circuits.
