LT1413S8 - Dual 5V Precision Op Amp | Analog Devices
部品番号: LT1413S8 ✓ 生産中LT1413S8 概要
An operational amplifier is a high-gain, differential analog building block used to amplify, buffer, filter, compare, and control voltage signals. The LT1413 belongs to the general-purpose operational-amplifier category within the broader amplifier and analog IC hierarchy. Its two amplifiers share a common supply but operate independently, allowing one package to implement functions such as sensor conditioning, error amplification, active filtering, or signal conversion.
The LT1413 emphasizes low offset voltage, low input bias current, and practical single-supply performance. The 60 µV offset and 0.1 nA offset current are particularly useful when reducing signal-chain errors near the input. A 950 kHz gain-bandwidth product supports moderate-frequency closed-loop operation, while the 0.3 V/µs slew rate allows comparatively rapid output transitions. The advertised output-current capability exceeds 10 mA at a 330 µA supply current.
The dual architecture improves board utilization by providing two amplifiers in one package. Its performance is characterized for both single 5 V supply operation and ±15 V supplies, although the manufacturer identifies 5 V as the optimized use case. The same-family LT1013 heritage provides a familiar general-purpose precision-amplifier position, while the LT1413 is described by Analog Devices as a low-cost, upgraded version of that industry-standard device.
Typical uses include 5 V sensor interfaces, low-level signal conditioning, active filters, instrumentation amplifiers, sample-and-hold stages, and general analog control loops. The SOIC package also allows a conventional surface-mount implementation without requiring a through-hole footprint. Designers should nevertheless verify output swing, input common-mode range, stability, and load drive at the intended supply voltage before finalizing a circuit.
For a new 5 V design, the primary design consideration is power-headroom management. Input and output operating ranges, common-mode limitations, and output-swing behavior must be checked against the actual signal. The manufacturer datasheet also identifies channel separation of 140 dB as an achieved specification, which can be valuable when both amplifiers operate on small signals in the same assembly.

主な用途
LT1413S8 の用途: 6 件s: 5 V Sensor Signal Conditioning, Precision Active Filtering, Industrial Instrumentation Control, Audio Preamplifier Signal Path, Low-Level Voltage Comparator, Portable Battery-Powered Analog Module.
5 V Sensor Signal Conditioning
The LT1413S8 fits 5 V sensor-conditioning circuits because its two amplifiers provide 60 µV input offset voltage and 0.1 nA input offset current, reducing error near the signal source. One channel can amplify a transducer output while the other provides buffering, gain, or active filtering. The 950 kHz gain-bandwidth product accommodates many low- to moderate-bandwidth industrial sensor signals, and the 0.3 V/µs slew rate gives practical response to output steps. Because the device is optimized for 5 V, designers still need to check input common-mode range and output swing against the sensor’s operating range.
おすすめ
Precision Active Filtering
The LT1413S8 can implement dual-section active filters in 5 V instrumentation because its 950 kHz gain-bandwidth product provides useful bandwidth for many precision and control applications. A 60 µV offset specification helps preserve low-level signal integrity, while the 0.1 nA input offset current is useful with high-impedance sources. The two amplifiers allow independent active sections within one 8-pin SOIC, reducing board area. Stability and noise gain must be evaluated for the selected topology, especially near the amplifier’s gain-bandwidth limit, and output swing must remain compatible with the filter’s signal excursions.
おすすめ
Industrial Instrumentation Control
The LT1413S8 is appropriate for low-level instrumentation and industrial control loops where two independent amplifiers are needed around a 5 V supply. Its 60 µV input offset voltage, 0.1 nA input offset current, and 140 dB channel separation help maintain signal integrity when both channels process related low-level signals. The dual 8-pin SOIC package simplifies board layout compared with two separate single amplifiers. Designers should verify common-mode behavior at the selected gain, ensure the selected feedback network remains stable, and confirm that load transients remain within the available output-current capability.
おすすめ
Audio Preamplifier Signal Path
The LT1413S8 can serve in a modest audio preamplifier or line-stage design when low offset and moderate bandwidth are sufficient. Its 60 µV input offset voltage, 950 kHz gain-bandwidth product, and 0.3 V/µs slew rate support low-level audio signal amplification without occupying excessive board space. The dual package can provide gain in one channel and unity or modest gain in the other. For high-fidelity applications, compare the LT1413 with a dedicated low-noise amplifier such as the NE5534 family, and verify input/output swing, distortion, noise, and stability under the intended 5 V bias conditions.
おすすめ
Low-Level Voltage Comparator
The LT1413S8 supports 5 V low-level comparison functions where input offset and input bias behavior affect the decision boundary. Its 60 µV offset and 0.1 nA offset current provide a defined error basis when comparing a sensor signal with a reference. One amplifier can form the comparator while the other amplifies or buffers the result, provided the design uses an appropriate feedback network. Designers must account for input common-mode limits, output saturation behavior, propagation delay at the selected frequency, and noise near the threshold when setting hysteresis.
おすすめ
Portable Battery-Powered Analog Module
The LT1413S8 is suitable for compact, battery-powered analog modules that use a 5 V rail and require two amplifiers rather than a single channel. The advertised capability of more than 10 mA output current at a 330 µA supply current is notable for a low-power circuit, while the 8-pin SOIC supports compact surface-mount assembly. The amplifier can buffer a sensor and perform gain or filtering within the same package. Designers should confirm quiescent current and shutdown requirements from the full manufacturer datasheet, estimate battery loading over the operating profile, and verify that the selected rail voltage keeps signals within the common-mode and output-swing limits.

設計ノート
The LT1413 is optimized for a 5 V rail, but the verified operating range extends down to 2 V and up to 18 V. Check the exact input common-mode range and output swing at the selected supply before committing the circuit. The manufacturer reports output current greater than 10 mA at a 330 µA supply current, but this should not be interpreted as proof that every load can be driven continuously. Confirm output-current, output-voltage, and thermal limits in the complete datasheet for the selected grade.
Place the supply bypass capacitor close to the SOIC power and ground pins, and route the amplifier’s ground return directly to the quiet analog ground structure. Keep feedback resistors and sensitive input traces compact to minimize parasitic capacitance and susceptibility to interference. Because the verified snippets do not provide the exact pin numbers, do not infer the footprint connection from this page; use the manufacturer pin drawing before PCB release.
Do not treat the 950 kHz gain-bandwidth product as usable closed-loop bandwidth at every gain. Closed-loop bandwidth depends on noise gain, and the 0.3 V/µs slew rate can become the limiting factor for large-amplitude outputs. Also avoid assuming rail-to-rail input or output behavior: the supplied data does not state those limits. Validate the signal path at worst-case supply, temperature, load, and output-amplitude conditions.
For low-level signals, account for the specified 60 µV input offset and 0.1 nA input offset current rather than relying on nominal gain alone. The 140 dB channel separation figure can help when both channels carry related small signals, but it does not remove errors caused by common supply impedance, ground-bounce coupling, or input overvoltage. Star-route or decouple supply branches where one amplifier’s output transient could otherwise modulate the other channel.
コンプライアンス情報
The verified data includes a lead-free #PBF ordering code but does not explicitly provide RoHS, REACH, AEC-Q100, halogen-free, or conflict-minerals statements. These fields remain unknown rather than being inferred. The component is a general-purpose precision operational amplifier rather than an automotive-qualified device.
