Key Features
- Adjustable 1.24 V to 10 V output using two external resistors with 1.225 V ±1.15% initial accuracy
- Two-terminal shunt configuration sinks up to 12 mA, eliminating the need for a separate bias supply
- Compact 3-pin TO-92 through-hole package simplifies prototyping and low-cost production voltage reference designs
Applications
The LM4041CIZ-ADJ/NOPB serves as a precision adjustable reference in ADC bias networks, DAC reference inputs, and portable instrumentation where a stable 1.24 V to 10 V reference is needed. Its two-terminal shunt architecture suits current-loop and battery-powered circuits that already carry a series resistor for biasing. Designers use it in handheld test equipment, signal conditioning modules, and power supply feedback dividers.

Frequently Asked Questions
How is the output voltage of the LM4041CIZ-ADJ/NOPB set, and what range is achievable?
The output voltage is set with two external resistors connected to the adjustment pin, and can be programmed anywhere from 1.24 V to 10 V. The nominal reference voltage at the output terminal is 1.225 V with ±1.15% initial accuracy, giving designers precise control over the reference level.
How much current can the LM4041CIZ-ADJ/NOPB sink, and why does that matter for circuit design?
The device sinks up to 12 mA in its shunt configuration, which means the designer must provide a series resistor to set operating current. This two-terminal approach is common in low-dropout reference networks and single-supply op-amp circuits where only a resistor and the shunt reference are needed.
When is the LM4041CIZ-ADJ/NOPB a better choice than a fixed 2.5 V or 3.3 V voltage reference?
It is preferred when the target system needs a non-standard reference voltage between 1.24 V and 10 V, or when the designer wants to tune the reference to exactly match the ADC full-scale input, avoiding error from mismatched fixed references and saving 1 to 2 discrete resistor-divider components.
