An inputclampdiodewitharesistortotheICinputterminalcanbeused. CAPACITIVE LOAD TOLERANCE The LMV721-N/722 can directly drive 4700pF in unity-gain without oscillation. The unity-gain follower is the most sensitive configuration to capacitive loading. Direct capacitive loading reduces the phase margin of amplifiers. The combination of the amplifier's output impedance and the capacitive load induces phase lag. This results in either an underdamped pulse response or oscillation. To drive a heavier capacitive load, circuit in Figure 23 can beused. Figure23. IndirectlyDrivingAcapacitiveLoadUsingResistiveIsolation In Figure 23, the isolation resistor R and the load capacitor C form a pole to increase stability by adding more ISO L phase margin to the overall system. the desired performance depends on the value of R . The bigger the R ISO ISO resistor value, the more stable V will be. Figure 24 is an output waveform of Figure 23 using 100kΩ for R OUT ISO and2000µFforC .

PulseResponseoftheLMV721-NCircuitinFigure23 The circuit in Figure 25 is an improvement to the one in Figure 23 because it provides DC accuracy as well as AC stability. If there were a load resistor in Figure 23, the output would be voltage divided by R and the load ISO resistor. Instead, in Figure 25, R provides the DC accuracy by using feed-forward techniques to connect V to F IN R . Caution is needed in choosing the value of R due to the input bias current of the LMV721-N/722. C and L F F R serve to counteract the loss of phase margin by feeding the high frequency component of the output signal ISO back to the amplifier's inverting input, thereby preserving phase margin in the overall feedback loop.

IndirectlyDrivingACapacitiveLoadwithDCAccuracy INPUT BIAS CURRENT CANCELLATION The LMV721-N/722 family has a bipolar input stage. The typical input bias current of LMV721-N/722 is 260nA with 5V supply. Thus a 100kΩ input resistor will cause 26mV of error voltage. By balancing the resistor values at both inverting and non-inverting inputs, the error caused by the amplifier's input bias current will be reduced.

Three-op-ampInstrumentationAmplifier The first stage of this instrumentation amplifier is a differential-input, differential-output amplifier, with two voltage followers.

LMV721-N, LMV722-N SNOS414I–AUGUST1999–REVISEDAUGUST2013 www.ti.com Here is a LMV721-N used as a microphone preamplifier. Since the LMV721-N is a low noise and low power op amp, it makes it an ideal candidate as a battery powered microphone preamplifier. The LMV721-N is connected in an inverting configuration. Resistors, R = R = 4.7kΩ, sets the reference half way between V = 3V and 1 2 CC ground. Thus, this configures the op amp for single supply use. The gain of the preamplifier, which is 50 (34dB), is set by resistors R = 10kΩ and R = 500kΩ. The gain bandwidth product for the LMV721-N is 10 MHz.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. Addendum-Page 1

PACKAGE OPTION ADDENDUM www.ti.com 6-Feb-2020 (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
