Product Summary
The LM4041C12IDCKR is a shunt voltage reference which is versatile, easy-to-use references with a vast array of applications. It requires no external resistors or capacitors for operation and are stable with all capacitive loads. Additionally, the LM4041C12IDCKR offers low dynamic impedance, low noise, and a low temperature coefficient to ensure a stable output voltage over a wide range of operating currents and temperatures. It uses fuse and Zener-zap reverse breakdown voltage trim during wafer sort to offer 5% (max) for the C grade. Thus, a great deal of flexibility is offered to designers in choosing the best cost-to-performance ratio for their applications. The LM4041C12IDCKR is available in a 1.225 V version (which requires an external resistor divider to set the output to a value of 1.225 V). Packaged in space-saving SC-70 requiring a minimum current of 45 mA (typ), the LM4041C12IDCKR also is ideal for portable applications. The LM4041C12IDCKR is characterized for operation over an ambient temperature range of –40℃ to 85℃.
