Features
Description
• Fixed 2.500V and 3.300V
• Tolerances to ±0.1% (25°C)
• Low output noise
• Low temperature coefficient to 100ppm/°C
• Small package
The FAN4040 series of precision shunt references are ideal
for space- and cost-sensitive applications. They are available
in two output voltages (2.500V and 3.300V) and with four
output voltage tolerances (0.1%, 0.2%, 0.5% and 1%). They
also have excellent temperature coefficients, to 100ppm/°C
for the tighter tolerance grades. The FAN4040 series has an
extended operating current range, sinking as much as 25mA.
• Extended operating current range
Applications
The FAN4040 series is available in SOT-23 package.
• Portable equipment
• Disk drives
• Instrumentation
• Audio equipment
• Data acquisition systems
