FAN4041
Precision Micropower Shunt Voltage Reference
Features
• • • • • • Adjustable shunt reference Tolerances to +0.
5% (25°C) Low output noise Low temperature coefficient to 100 ppm/°C max Small packages Extended operating current range
Description
The FAN4041 adjustable precision shunt references are ideal for space- and cost-sensitive applications.
They are available with output voltage tolerances of 0.
5% and 1%.
They also have excellent temperature coefficients, to 100ppm/°C for the tighter tolerance grades.
The FAN4041 series has an extended operating current range, sinking as much as 25mA.
The FAN4041 series is available in SOT-23 and TO-92 packages.
Applications
• • • • • Portable equipment Disk drives Instrumentation Audio equipment Data acquisition systems
