LM324ANE4 - Quad 14-PDIP Op Amp | Texas Instruments
MPN: LM324ANE4 ✓ פעילLM324ANE4 סקירה
An operational amplifier is an analog integrated circuit that uses high-gain differential amplification to compare and process voltages. The LM324 family belongs to the operational-amplifier hierarchy within analog and signal-chain ICs. Four amplifiers in one package can support buffer, amplifier, comparator, summing, difference, filtering, and level-conversion functions while reducing board area and external component count.
The LM324ANE4 combines four amplifier channels with single-supply operation. The component documentation describes operation from split supplies with a total supply difference from 3 V to 32 V, and notes a typical low supply-current drain of 0.8 mA. Its input common-mode voltage range includes ground, allowing the amplifier to process input signals near the lower supply rail. This rail-to-near-ground input capability is particularly useful in systems powered from a single positive supply.
Each internal amplifier includes the input and output functions needed for conventional closed-loop analog designs. Feedback components establish gain and filtering behavior, while the open-loop characteristics of the internal transistor stages determine signal amplification, common-mode behavior, and output-drive capability. Because all four channels share one package and supply pins, the device is especially practical when a board needs several similar signal-conditioning channels rather than unrelated mixed functions.
Typical applications include low-frequency audio and control circuits, DC signal amplifiers, active filters, sensor-signal conditioning, and general industrial interface boards. The four-channel organization can simplify a design requiring multiple gain stages or parallel low-bandwidth analog channels. The 14-PDIP package also supports through-hole assembly and prototype-board layouts where a surface-mount package would be inconvenient.
Designers should verify the exact input common-mode limits, output-swing limits, supply-current behavior, electrical characteristics, and operating-temperature grade in the manufacturer datasheet before finalizing signal headroom. Input and output stability also depends on the selected feedback network, source impedance, load, decoupling, and board layout. Place bypass capacitors close to the supply pins and keep sensitive input nodes away from high-current return paths.
This product page combines manufacturer-product information, datasheet references, package and pinout details, application guidance, and same-footprint alternative analysis. It is designed to help engineers evaluate the LM324ANE4 alongside other Texas Instruments LM324 ordering codes while preserving the constraints of a 14-PDIP, four-channel general-purpose amplifier.

DC Sensor Signal Conditioning
The LM324ANE4 suits low-frequency sensor interfaces that require amplification from a signal referenced near ground. Its input common-mode range includes ground, which is useful when a sensor produces a small positive voltage from 0 V upward, while four channels allow related signals to be conditioned in one 14-PDIP package. According to the Texas Instruments LM324 documentation, the device is a low-power quad amplifier designed for single-supply operation. Designers should choose resistor values that keep the closed-loop output within the datasheet swing limits and use nearby supply bypassing to reduce supply-related disturbance. The amplifier is best suited to sensors with bandwidth well below the LM324’s gain-bandwidth limit.
מומלץ
Active Audio and Control Filtering
The LM324ANE4 is appropriate for low-frequency active filters and control-signal amplifiers built with conventional external resistors and capacitors. Four amplifier sections permit cascaded stages or parallel channels without using four separate packages, while the 3 V to 32 V split-supply total-voltage capability supports a broad range of rails. The device’s single-supply compatibility makes it practical in compact audio and industrial-control boards. According to the LM324ANE4 datasheet information, input common-mode operation includes ground. Verify the closed-loop bandwidth, output swing, and stability for each filter topology, especially when signal levels approach either supply rail.
מומלץ
Industrial Control Signal Amplification
The LM324ANE4 can amplify and buffer low-bandwidth control signals in industrial equipment where four similar channels are needed on one board. Its 14-PDIP format is useful for legacy control systems, test fixtures, and through-hole assembly, while the typical 0.8 mA supply-current drain supports low-power operation according to the LM324ANE4 documentation. The quad arrangement can implement error amplifiers, comparators with reference networks, actuator-signal conditioners, and status-monitoring channels. Keep sensitive inputs away from switching nodes and relay-return currents, and confirm operating-temperature suitability and output-current requirements against the manufacturer datasheet.
מומלץ
Precision Test and Measurement Buffering
The LM324ANE4 is suitable for general-purpose buffering and low-level amplification in laboratory or field test equipment when the required bandwidth and accuracy fall within its data-sheet limits. Four channels make it possible to condition multiple measurement inputs while reducing component count. The input common-mode range including ground supports systems whose signals are referenced to the lower rail, and split-supply operation is possible with a total voltage difference from 3 V to 32 V. According to the Texas Instruments product page, the LM324 is a low-power quad amplifier intended for wide-range single-supply operation. For precision measurements, compare offset voltage, bias current, open-loop gain, and drift before selecting the device.
מומלץ
Power-Supply Feedback and Monitoring
The LM324ANE4 can implement error amplifiers, feedback comparators, and auxiliary monitoring channels in a power-control board because it combines four general-purpose amplifiers with low-power single-supply capability. A typical arrangement compares a scaled output voltage with a reference and drives an external compensation network or control stage. The 0.8 mA typical supply-current drain reported for the LM324ANE4 is useful where amplifier loading must remain modest. The package should be positioned away from heat-producing elements and switching nodes, while input and output paths should avoid ground-current coupling. Confirm loop stability and saturation recovery before operating near the output limits.
מומלץ
Single-Supply Interface Conditioning
The LM324ANE4 is well matched to legacy single-supply interfaces that accept signals referenced to ground and need buffering before entering an ADC, comparator, or controller. The manufacturer identifies the LM324 as a low-power quad operational amplifier designed for single-supply operation across a wide voltage range. Its input common-mode range includes ground, while the 14-PDIP package simplifies through-hole prototype construction. Use the four channels for independent gain and impedance-matching stages, but verify the input bias current against high-impedance sensors and confirm output-swing headroom for the ADC’s full-scale range. Supply decoupling and quiet grounding remain essential for small-signal accuracy.

הערות תכנון
Do not assume that an LM324-family member can replace every ordering code without qualification. LM324ANE4, LM324AN, LM324N, and LM324NG share the general LM324 architecture, but temperature grade, qualification, and ordering details can differ. Compare the manufacturer ordering-information table and electrical-characteristics tables for gain bandwidth, slew rate, input offset, bias current, common-mode range, output swing, and supply limits before approving a substitution.
The documented typical supply-current drain is 0.8 mA for the LM324ANE4, but total board consumption also includes output-current demand and external circuitry. Place a supply-bypass capacitor close to pin 11 and provide a low-impedance return path from pin 4. Keep sensitive input returns separate from output and load currents where possible, because shared ground paths can convert load current into input error voltage.
Route the four amplifier channels in the same order as their pins, and keep feedback resistors and capacitors physically close to the associated input and output pins. Longer loops can pick up noise or interact with parasitic capacitance. Place bypass capacitance at the supply pins, use a ground plane where practical, and isolate each channel’s input node from adjacent high-impedance nodes to reduce crosstalk and oscillation risk.
Confirm that the required closed-loop gain and signal frequency remain within the LM324 gain-bandwidth and slew-rate limits listed in the manufacturer datasheet. For sensor interfaces, also compare source impedance with input bias current and verify that the signal stays within the common-mode range, which includes ground for this family. Use gain stages close to the signal source when source impedance is high.
