www.fairchildsemi.com FAN4040 Precision Micropower Shunt Voltage Reference Features • • • • • • • Fixed 2.500V, 3.300V and 5.00V Tolerances to ±0.1% (25°C) Low output noise Low temperature coefficient to 100ppm/°C Small package Extended operating current range Extended temperature range Description The FAN4040 series of precision shunt references are ideal for space- and cost-sensitive applications. They are available in three output voltages (2.500V, 3.300V and 5.00V) 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. The FAN4040 series is available in SOT-23 package. Applications • • • • • Portable equipment Disk drives Instrumentation Audio equipment Data acquisition systems Connection Diagrams SOT-23 + 1 3* – 2 *This pin must be left floating or connected to pin 2.
