LMV2011 SNOSA32C – AUGUST 2003 – REVISED MARCH 2013 www.ti.com APPLICATION INFORMATION THE BENEFITS OF LMV2011 NO 1/f NOISE Using patented methods, the LMV2011 eliminates the 1/f noise present in other amplifiers. That noise, which increases as frequency decreases, is a major source of measurement error in all DC-coupled measurements. Low-frequency noise appears as a constantly-changing signal in series with any measurement being made.
PAGE 11
LMV2011 www.ti.com SNOSA32C – AUGUST 2003 – REVISED MARCH 2013 MORE BENEFITS The LMV2011 offers the benefits mentioned above and more. It has a rail-to-rail output and consumes only 950µA of supply current while providing excellent DC and AC electrical performance. In DC performance, the LMC2001 achieves 130dB of CMRR, 120dB of PSRR and 130dB of open loop gain. In AC performance, the LMV2011 provides 3MHz of gain-bandwidth product and 4V/µs of slew rate.

LMV2011 SNOSA32C – AUGUST 2003 – REVISED MARCH 2013 www.ti.com INPUT CURRENTS The LMV2011's input currents are different than standard bipolar or CMOS input currents in that it appears as a current flowing in one input and out the other. Under most operating conditions, these currents are in the picoamp level and will have little or no effect in most circuits. These currents tend to increase slightly when the common-mode voltage is near the minus supply (See the Typical Performance Characteristics).

LMV2011 SNOSA32C – AUGUST 2003 – REVISED MARCH 2013 www.ti.com In the case of the inverting configuration, it is also possible to increase the input impedance of the overall amplifier, by raising the value of R1, without having to increase the feed-back resistor, R2, to impractical values, by utilizing a "Tee" network as feedback. See the LMC6442 data sheet (Application Notes section) for more details on this. Figure 36.
