A new family of high-precision, high-performance amplifiers heralds National Semiconductor's entry into the burgeoning precision market.

National's LMP linear monolithic precision line addresses existing precision applications and positions National to provide next-generation products for a market that is increasingly focused on accuracy.

The first parts in the new LMP family are the LMP2011, LMP2012 and LMP2014, for broad-based applications in industrial, medical and automotive electronics.

The LMP2011/12/14 are single, dual and quad high-precision amplifiers with a very low offset voltage of 25uV and wide bandwidth of 3MHz for accurate signal amplification and reduced error for applications where DC precision and strong AC specifications are needed.

"National Semiconductor is very excited to introduce the new LMP line and announce a new thrust area for the company", said Erroll Dietz, Vice President of National's Amplifier Product Group.

"Our goal is to provide customers with the highest-accuracy parts on the market, and we're on track to do just that".

"Our high-performance family of analogue amplifiers not only provides very high precision over time and temperature, but also an extended temperature range".

"Thanks to National's long history of innovation in analogue design, we're in a great position to support a broad range of demanding precision applications".

National's LMP2011/12/14, in addition to having very low input offset voltage, are very stable over time and temperature (0.015uV/C).

These parts feature a high common mode rejection ratio, power supply rejection ratio, and high open loop gain, all in excess of 120dB.

The LMP2011/12/14 also provide flat band noise of 35nV/(rt)Hz with no 1/f noise.

National's LMP2011 is available now in SOT23-5 packaging and is priced at $0.98, the LMP2012 is available now in MSOP-8 packaging and is priced at $1.40, and the LMP2014 is available now in TSSOP-14 packaging and is priced at $2.50, all in 1000-unit quantities.
