The LMV321-N is the single channel version. The LMV321-N/LMV358N/LMV324-N are the most cost effective solutions for applications where low voltage operation, space efficiency, and low price are important. They offer specifications that meet or exceed the familiar LM358/LM324. The LMV321-N/LMV358-N/LMV324-N have rail-to-rail output swing capability and the input common-mode voltage range includes ground. They all exhibit excellent speed to power ratio, achieving 1 MHz of bandwidth and 1 V/µs slew rate with low supply current. The LMV321-N is available in the space saving 5-Pin SC70, which is approximately half the size of the 5Pin SOT23. The small package saves space on PC boards and enables the design of small portable electronic devices. It also allows the designer to place the device closer to the signal source to reduce noise pickup and increase signal integrity. The chips are built with Texas Instruments's advanced submicron silicon-gate BiCMOS process. The LMV321-N/LMV358-N/LMV324-N have bipolar input and output stages for improved noise performance and higher output current drive.

The low profile of the LMV321-N/LMV358-N/LMV324-N make them possible to use in PCMCIA type III cards. Signal Integrity Signals can pick up noise between the signal source and the amplifier. By using a physically smaller amplifier package, the LMV321-N/LMV358-N/LMV324-N can be placed closer to the signal source, reducing noise pickup and increasing signal integrity. Simplified Board Layout These products help you to avoid using long PC traces in your PC board layout. This means that no additional components, such as capacitors and resistors, are needed to filter out the unwanted signals due to the interference between the long PC traces. Low Supply Current These devices will help you to maximize battery life. They are ideal for battery powered systems. Low Supply Voltage Texas Instruments provides guaranteed performance at 2.7V and 5V. These guarantees ensure operation throughout the battery lifetime. Rail-to-Rail Output Rail-to-rail output swing provides maximum possible dynamic range at the output. This is particularly important when operating on low supply voltages. Input Includes Ground Allows direct sensing near GND in single supply operation. Protection should be provided to prevent the input voltages from going negative more than −0.3V (at 25°C). An input clamp diode with a resistor to the IC input terminal can be used. Ease of Use and Crossover Distortion The LMV321-N/LMV358-N/LMV324-N offer specifications similar to the familiar LM324-N. In addition, the new LMV321-N/LMV358-N/LMV324-N effectively eliminate the output crossover distortion. The scope photos in Figure 49 and Figure 50 compare the output swing of the LMV324-N and the LM324-N in a voltage follower configuration, with VS = ± 2.5V and RL (= 2 kΩ) connected to GND. It is apparent that the crossover distortion has been eliminated in the new LMV324-N. Figure 49.

Output Swing of LM324 CAPACITIVE LOAD TOLERANCE The LMV321-N/LMV358-N/LMV324-N can directly drive 200 pF 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, the circuit in Figure 51 can be used. Figure 51. Indirectly Driving a Capacitive Load Using Resistive Isolation In Figure 51 , the isolation resistor RISO and the load capacitor CL form a pole to increase stability by adding more phase margin to the overall system. The desired performance depends on the value of RISO. The bigger the RISO resistor value, the more stable VOUT will be. Figure 52 is an output waveform of Figure 51 using 620Ω for RISO and 510 pF for CL.. Figure 52. Pulse Response of the LMV324 Circuit in Figure 51 The circuit in Figure 53 is an improvement to the one in Figure 51 because it provides DC accuracy as well as AC stability. If there were a load resistor in Figure 51, the output would be voltage divided by RISO and the load resistor. Instead, in Figure 53, RF provides the DC accuracy by using feed-forward techniques to connect VIN to RL. Caution is needed in choosing the value of RF due to the input bias current of theLMV321-N/LMV358N/LMV324-N. CF and RISO serve to counteract the loss of phase margin by feeding the high frequency component of the output signal back to the amplifier's inverting input, thereby preserving phase margin in the overall feedback loop. Increased capacitive drive is possible by increasing the value of CF . This in turn will slow down the pulse response.

Indirectly Driving A Capacitive Load with DC Accuracy INPUT BIAS CURRENT CANCELLATION The LMV321-N/LMV358-N/LMV324-N family has a bipolar input stage. The typical input bias current of LMV321N/LMV358-N/LMV324-N is 15 nA with 5V supply. Thus a 100 kΩ input resistor will cause 1.5 mV 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. The circuit in Figure 54 shows how to cancel the error caused by input bias current. Figure 54. Cancelling the Error Caused by Input Bias Current TYPICAL SINGLE-SUPPLY APPLICATION CIRCUITS Difference Amplifier The difference amplifier allows the subtraction of two voltages or, as a special case, the cancellation of a signal common to two inputs. It is useful as a computational amplifier, in making a differential to single-ended conversion or in rejecting a common mode signal. 16 Submit Documentation Feedback Copyright © 2000–2013, Texas Instruments Incorporated Product Folder Links: LMV321-N LMV321-N-Q1 LMV358-N LMV358-N-Q1 LMV324-N LMV324-N-Q1 LMV321-N, LMV321-N-Q1, LMV358-N, LMV358-N-Q1 LMV324-N, LMV324-N-Q1 www.ti.com SNOS012I – AUGUST 2000 – REVISED FEBRUARY 2013 Figure 55. Difference Amplifier Instrumentation Circuits The input impedance of the previous difference amplifier is set by the resistors R1, R2, R3, and R4. To eliminate the problems of low input impedance, one way is to use a voltage follower ahead of each input as shown in the following two instrumentation amplifiers. Three-Op-Amp Instrumentation Amplifier The quad LMV324 can be used to build a three-op-amp instrumentation amplifier as shown in Figure 56. Figure 56. Three-Op-Amp Instrumentation Amplifier The first stage of this instrumentation amplifier is a differential-input, differential-output amplifier, with two voltage followers. These two voltage followers assure that the input impedance is over 100 MΩ. The gain of this instrumentation amplifier is set by the ratio of R2/R1. R3 should equal R1, and R4 equal R2. Matching of R3 to R1 and R4 to R2 affects the CMRR. For good CMRR over temperature, low drift resistors should be used. Making R4 slightly smaller than R2 and adding a trim pot equal to twice the difference between R2 and R4 will allow the CMRR to be adjusted for optimum performance. Two-Op-Amp Instrumentation Amplifier A two-op-amp instrumentation amplifier can also be used to make a high-input-impedance DC differential amplifier (Figure 57). As in the three-op-amp circuit, this instrumentation amplifier requires precise resistor matching for good CMRR. R4 should equal R1 and, R3 should equal R2.

Two-Op-Amp Instrumentation Amplifier Single-Supply Inverting Amplifier There may be cases where the input signal going into the amplifier is negative. Because the amplifier is operating in single supply voltage, a voltage divider using R3 and R4 is implemented to bias the amplifier so the input signal is within the input common-mode voltage range of the amplifier. The capacitor C1 is placed between the inverting input and resistor R1 to block the DC signal going into the AC signal source, VIN. The values of R1 and C1 affect the cutoff frequency, fc = 1/2πR1C1. As a result, the output signal is centered around mid-supply (if the voltage divider provides V+/2 at the noninverting input). The output can swing to both rails, maximizing the signal-to-noise ratio in a low voltage system. Figure 58. Single-Supply Inverting Amplifier ACTIVE FILTER Simple Low-Pass Active Filter The simple low-pass filter is shown in Figure 59. Its low-frequency gain (ω → 0) is defined by −R3/R1. This allows low-frequency gains other than unity to be obtained. The filter has a −20 dB/decade roll-off after its corner frequency fc. R2 should be chosen equal to the parallel combination of R1 and R3 to minimize errors due to bias current. The frequency response of the filter is shown in Figure 60. 18 Submit Documentation Feedback Copyright © 2000–2013, Texas Instruments Incorporated Product Folder Links: LMV321-N LMV321-N-Q1 LMV358-N LMV358-N-Q1 LMV324-N LMV324-N-Q1 LMV321-N, LMV321-N-Q1, LMV358-N, LMV358-N-Q1 LMV324-N, LMV324-N-Q1 www.ti.com SNOS012I – AUGUST 2000 – REVISED FEBRUARY 2013 Figure 59.

Frequency Response of Simple Low-Pass Active Filter in Figure 11 Note that the single-op-amp active filters are used in the applications that require low quality factor, Q( ≤ 10), low frequency (≤ 5 kHz), and low gain (≤ 10), or a small value for the product of gain times Q (≤ 100). The op amp should have an open loop voltage gain at the highest frequency of interest at least 50 times larger than the gain of the filter at this frequency. In addition, the selected op amp should have a slew rate that meets the following requirement: Slew Rate ≥ 0.5 × (ω HVOPP) × 10−6 V/µsec (1) where ωH is the highest frequency of interest, and VOPP is the output peak-to-peak voltage.

As shown in Figure 62, resistors become capacitors, and capacitors become resistors. The resulted high pass filter has the same corner frequency and the same maximum gain as the previous 2nd-order low pass filter if the same components are chosen.

Two diodes have been used to separate the charge and discharge paths to capacitor C. Figure 64. Pulse Generator When the output voltage VO is first at its high, VOH, the capacitor C is charged toward VOH through R2. The voltage across C rises exponentially with a time constant τ = R2C, and this voltage is applied to the inverting input of the op amp. Meanwhile, the voltage at the non-inverting input is set at the positive threshold voltage (VTH+) of the generator. The capacitor voltage continually increases until it reaches VTH+, at which point the output of the generator will switch to its low, VOL which 0V is in this case. The voltage at the non-inverting input is switched to the negative threshold voltage (VTH−) of the generator. The capacitor then starts to discharge toward VOL exponentially through R1, with a time constant τ = R1C. When the capacitor voltage reaches VTH−, the output of the pulse generator switches to VOH. The capacitor starts to charge, and the cycle repeats itself. 24 Submit Documentation Feedback Copyright © 2000–2013, Texas Instruments Incorporated Product Folder Links: LMV321-N LMV321-N-Q1 LMV358-N LMV358-N-Q1 LMV324-N LMV324-N-Q1 LMV321-N, LMV321-N-Q1, LMV358-N, LMV358-N-Q1 LMV324-N, LMV324-N-Q1 www.ti.com SNOS012I – AUGUST 2000 – REVISED FEBRUARY 2013 Figure 65.

Squarewave Generator CURRENT SOURCE AND SINK The LMV321-N/LMV358-N/LMV324-N can be used in feedback loops which regulate the current in external PNP transistors to provide current sources or in external NPN transistors to provide current sinks. Fixed Current Source A multiple fixed current source is shown in Figure 68. A voltage (VREF = 2V) is established across resistor R3 by the voltage divider (R3 and R4). Negative feedback is used to cause the voltage drop across R1 to be equal to VREF. This controls the emitter current of transistor Q1 and if we neglect the base current of Q1 and Q2, essentially this same current is available out of the collector of Q1. Large input resistors can be used to reduce current loss and a Darlington connection can be used to reduce errors due to the β of Q1. The resistor, R2, can be used to scale the collector current of Q2 either above or below the 1 mA reference value. Figure 68.

Figure 72 shows a comparator with hysteresis. The hysteresis is determined by the ratio of the two resistors. VTH+ = VREF/(1+R 1/R2)+VOH/(1+R2/R1) VTH− = VREF/(1+R 1/R2)+VOL/(1+R2/R1) VH = (VOH−VOL)/(1+R 2/R1) (30) (31) (32) where VTH+: Positive Threshold Voltage VTH−: Negative Threshold Voltage VOH: Output Voltage at High VOL: Output Voltage at Low VH: Hysteresis Voltage Since LMV321-N/LMV358-N/LMV324-N have rail-to-rail output, the (VOH−VOL) is equal to VS, which is the supply voltage. VH = VS/(1+R2/R1) (33) The differential voltage at the input of the op amp should not exceed the specified absolute maximum ratings. For real comparators that are much faster, we recommend you use Texas Instruments's LMV331/LMV93/LMV339, which are single, dual and quad general purpose comparators for low voltage operation.

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
