LMV751 SNOS468E – AUGUST 1999 – REVISED MARCH 2013 www.ti.com APPLICATION HINTS Noise There are many sources of noise in a system: thermal noise, shot noise, 1/f, popcorn noise, resistor noise, just to name a few. In addition to starting with a low noise op amp, such as the LMV751, careful attention to detail will result in the lowest overall noise for the system.
PAGE 9
LMV751 www.ti.com SNOS468E – AUGUST 1999 – REVISED MARCH 2013 Actual resistor noise measurements may have more noise than the calculated value. This additional noise component is known as excess noise. Excess noise has a 1/f spectral response, and is proportional to the voltage drop across the resistor. It is convenient to define a noise index when referring to excess noise in resistors.

LMV751 SNOS468E – AUGUST 1999 – REVISED MARCH 2013 www.ti.com Loading The LMV751 is a low noise, high speed op amp with excellent phase margin and stability. Capacitive loads up to 1000 pF can be handled, but larger capacitive loads should be isolated from the output. The most straightforward way to do this is to put a resistor in series with the output. This resistor will also prevent excess power dissipation if the output is accidentally shorted.
