LM4041CIM3-ADJ Datasheet – Shunt Voltage Reference – National

Part Number : LM4041CIM3-ADJ

Function : Precision Micropower Shunt Voltage Reference

Manufactures : National Semiconductor

General Description

Ideal for space critical applications, the LM4041 precision voltage reference is available in the sub-miniature (3 mm x 1.3 mm) SOT-23 surface-mount package. The LM4041’s advanced design eliminates the need for an external stabilizing capacitor while ensuring stability with any capacitive load, thus making the LM4041 easy to use. Further reducing design effort is the availability of a fixed (1.225V) and adjust able reverse breakdown voltage. The minimum operating current is 60 µA for the LM4041-1.2 and the LM4041-ADJ. Both versions have a maximum operating current of 12 mA. The LM4041 utilizes fuse and zener-zap reverse breakdown or reference voltage trim during wafer sort to ensure that the prime parts have an accuracy of better than ±0.1% (A grade) at 25˚C. Bandgap reference temperature drift curvature correction and low dynamic impedance ensure stable reverse breakdown voltage accuracy over a wide range of operating temperatures and currents.

REF01 datasheet


GENERAL Description

The REF01 precision voltage reference providesa stable 10V output that can be adjusted over a 3% range withminimal effect on temperature stability.Single-supply operation over an input voltage range of12 V to 40 V,a low current drain of 1 mA, and excellent temperature stability are achieved with an improved band gap design. Low cost, low noise, and low power make the REF01 an excellent choice whenever a stable voltage reference is required. Applications include DACs and ADCs, portable instrumentation, and digital voltmeters. Fullmilitary temperature range devices with screening to MIL-STD-883 are available. Fornew designs, refer to ADR01.
