LM4041DFTA

LM4041DFTA is a Texas Instruments precision shunt voltage reference (LM4041 family). It acts like a stable reference diode: when biased with current, it clamps its output node to a fixed voltage that is largely insensitive to supply or load changes. It’s a small, two-terminal, low-power device used to bias ADCs, DACs, and precision analog circuits.
How it works: connect the anode to ground and the cathode to the reference node through a resistor from a supply. The resistor sets the operating current within the device’s specified range; the LM4041 maintains its nominal voltage at the cathode.
Key features: low dynamic impedance, good line/load regulation, and low noise. Output options span fixed voltages in the LM4041 family; versions like DFTA denote a particular package/lead-free variant.
Common uses: precision voltage references for converters and sensors, bias/reference generation in analog circuits, and calibration references.
Notes: check the datasheet for the exact Vout option, operating current ranges, and packaging details for LM4041DFTA.

LM4041DFTA is a precision shunt voltage reference. Key features:
- Three-terminal shunt reference with fixed/adjustable output options.
- Tight initial accuracy and low drift (temperature-dependent variants available).
- Low dynamic impedance for excellent load regulation.
- Wide operating current range (supports very low power to higher bias for stability).
- Low noise and good line regulation.
- Short-circuit protection and robustness to variations in supply and load.
- Available in compact surface-mount DFTA packaging (industry-standard footprints).
Note: Exact voltage, current range, and tempco are variant-dependent. Please specify the target output voltage and operating conditions to get precise specs.

LM4041DFTA is a 3-pin surface-mount device in a SOT-23 (SC-70-3) style package.

- Pin count: 3 pins
- Function: Three-terminal precision shunt voltage reference. Pins: A = Anode (ground/return), K = Cathode (to supply via bias resistor), R = Reference/output (Vref). The device shunts current from K to A to hold the R pin at a fixed reference voltage relative to A.

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits (ICs) and related software.
