Precision Amps Up Accuracy Bars November 2004 Issue Published Date: November 17, 2004
Poised for high-precision and high-accuracy applications in a variety of markets, the LMP2011/12/14 single, dual and quad amplifiers specify an input offset voltage of 25 µV and a wide bandwidth of 3 MHz. The devices are said to be very stable over time and temperature, in the realm of 0.015 µV/°C. Other shared features include a high common mode rejection ratios, high power supply rejection ratios, and high open loop gains, all in excess of 120 dB. Additionally, each amplifier provides a flat-band noise of 35 nV/Hz with no 1/f noise. Prices for the LMP2011 (SOT23-5), LMP2012 (MSOP-8 and SOIC-8), and LMP2014 (TSSOP-14) are $0.98, $1.40, and $1.80 each/1,000, respectively. NATIONAL SEMICONDUCTOR, Santa Clara, CA. (800) 272-9959.
