Description for the LM4040
The LM4040 series of shunt voltage references areversatile, easy-to-use references that cater to a vast array of applications. The 2-pinfixed-output device requires no external capacitors for operation and is stable with all capacitiveloads. Additionally, the reference offers low dynamic impedance, low noise, and low temperaturecoefficient to ensure a stable output voltage over a wide range of operating currents andtemperatures. The LM4040 uses fuse and Zener-zap reverse breakdown voltage trim during wafer sortto offer four output voltage tolerances, ranging from 0.1% (max) for the A grade to 1% (max) forthe D grade. Thus, a great deal of flexibility is offered to designers in choosing the bestcost-to-performance ratio for their applications.
Packaged in space-saving SC-70 and SOT-23-3 packages and requiring a minimum current of45 µA (typ), the LM4040 also is ideal for portable applications. The LM4040xI is characterized foroperation over an ambient temperature range of –40°C to 85°C. The LM4040xQ is characterized foroperation over an ambient temperature range of –40°C to 125°C.
NEW - You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.
A custom reel
is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.
Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.TI often ships
devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
