High Precision Amplifiers Boost Accuracy

Santa Clara, Calif. — October 5, 2004 — Today National Semiconductor Corp. made its foray into the precision market with a family of high-precision, high-performance amplifiers that are said to improve accuracy in industrial, medical and automotive applications.

National's linear monolithic precision (LMP) 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 25 μV and a wide bandwidth of 3 MHz for accurate signal amplification and reduced error for applications where DC precision and strong AC specifications are needed.

National's high-performance family of analog amplifiers not only provides very high precision over time and temperature, but also an extended temperature range, said Erroll Dietz, vice president of National's Amplifier product group.

National's LMP2011/12/14, in addition to having very low input offset voltage (Vos), are very stable over time and temperature (0.015 μV/°C). These parts feature a high common mode rejection ratio, power supply rejection ratio, and high open loop gain, all in excess of 120 dB. The LMP2011/12/14 also provide flat band noise of 35 nV per root hertz with no 1/f noise.

National's LMP2011 is available now in SOT23-5 packaging and is priced at 98 cents. The LMP2012 is available now in MSOP-8 and SOIC-8 packaging and is priced at $1.40, and the LMP2014 is available now in TSSOP-14 packaging and is priced at $1.80 in 1,000-unit quantities.
