SM73308

SM73308 Low Offset, Low Noise, RRO Operational Amplifier SM73308 June 1, 2011 Low Offset, Low Noise, RRO Operational Amplifier General Description The SM73308 is a Single low noise precision operational amplifier intended for use in a wide range of applications. Other important characteristics include: an extended operating temperature range of −40°C to 125°C, the tiny SC70-5 package, and low input bias current. The extended temperature range of −40°C to 125°C allows the SM73308 to accommodate a broad range of applications. The SM73308 expands National Semiconductor’s Silicon Dust™ amplifier portfolio offering enhancements in size, speed, and power savings. The SM73308 is guaranteed to operate over the voltage range of 2.7V to 5.0V and has railto-rail output. The SM73308 is designed for precision, low noise, low voltage, and miniature systems. This amplifier provides rail-to-rail output swing into heavy loads. The maximum input offset is 850 μV at room temperature and the input common mode voltage range includes ground. The SM73308 is offered in the tiny SC70-5 package.
