LT1367CS - Quad Precision Rail-to-Rail Op Amp | Analog Devices
MPN: LT1367CS ✓ AktifLT1367CS Genel Bakış
An operational amplifier, or op amp, is a high-gain analog building block used in the amplifier IC category to amplify, buffer, compare, filter, and perform analog signal processing. The LT1367 belongs to the broader precision amplifier hierarchy, combining differential input stages, high open-loop gain, and rail-to-rail signal capability in one integrated circuit.
The LT1367CS uses a standard quad layout in the 14-lead SO package. This arrangement allows four precision amplifier channels to be placed on a single PCB footprint. Rail-to-rail input operation is valuable when signals may approach either supply rail, while rail-to-rail output capability helps preserve output-voltage range. The verified distributor listing identifies the LT1367 as a four-circuit, rail-to-rail amplifier in a 14-SO package.
The family documentation states that the LT1367 can serve as a plug-in replacement for many standard op amps while improving input and output range and precision. Because the LT1367CS is a quad device in a 14-lead package, board-level substitution requires attention to channel order, supply pins, exposed pad availability, input common-mode limits, output swing, stability, and load capability rather than package name alone.
Typical uses include precision signal conditioning, low-frequency analog filtering, transducers, instrumentation, buffered sensor interfaces, and general analog signal chains. The 400 kHz gain-bandwidth figure makes it more appropriate for moderate-bandwidth precision and general-purpose amplification than for high-speed video or RF signal paths.
Designers should verify the complete electrical limits from the manufacturer datasheet, including supply voltage, input offset voltage, input bias current, output swing, slew rate, settling time, noise, and temperature range. Decoupling should follow the datasheet recommendations, and output loads must remain within the specified capacitive and resistive limits to preserve stability.
This product page consolidates verified manufacturer and distributor information, exact package identification, sourcing details, and pin-compatible replacement findings. It also separates directly supported LT1367CS facts from cross-reference candidates and identifies where additional electrical data is required for a final design decision.

LT1367CS için uygundur 6 uygulamas: Precision Instrumentation Signal Conditioning, Buffered Sensor and Transducer Interface, Active Analog Filtering, General-Purpose Four-Channel Analog Amplification, Precision Reference and Buffering, Low-Frequency Audio and Communication Control.
Precision Instrumentation Signal Conditioning
The LT1367CS fits instrumentation front ends that require four precision amplifier channels in one 14-lead SO package. Its rail-to-rail input characteristic is useful when sensor outputs move close to the lower or upper supply rail, while rail-to-rail output helps retain signal range in the next processing stage. The verified 400 kHz gain-bandwidth product is appropriate for moderate-bandwidth sensor conditioning rather than wideband digitization front ends. Designers should verify input offset, bias current, noise, and common-mode accuracy from the manufacturer data sheet before setting the gain. A practical implementation places local supply decoupling at the IC and keeps high-impedance sensor connections short to reduce leakage and interference.

Buffered Sensor and Transducer Interface
The LT1367CS can buffer sensor and transducer outputs where the source impedance is high and four channels share a common analog board. Rail-to-rail input operation preserves headroom when the input approaches a supply limit, and the 400 kHz gain-bandwidth product supports modest-frequency amplification and active-filter stages. Each amplifier still requires stability analysis for the actual source impedance, load, and feedback network. Input bias current is especially important because it can create offset in a high-impedance sensor interface. The board should use short traces, guard or shield techniques where appropriate, and a clean local ground reference to avoid converting common-mode interference into signal error.
Önerilen
Active Analog Filtering
The LT1367CS is suitable for first- and second-order active filters in low-to-moderate frequency analog channels. Its 400 kHz gain-bandwidth product provides more bandwidth than many precision-focused amplifier choices and allows useful closed-loop bandwidth when higher noise gain is required. Rail-to-rail output improves filter swing toward the supply rails, although capacitor and resistor tolerances will often determine real filter accuracy. Before implementation, confirm the amplifier's gain-bandwidth, slew-rate, open-loop-gain, and capacitive-load behavior against the filter's corner frequency and step response. Place filter resistors and capacitors close to the relevant pins and check output loading for every stage.

General-Purpose Four-Channel Analog Amplification
The LT1367CS consolidates four general-purpose precision amplifier channels into one 14-lead SO package, reducing board area compared with four separate single amplifiers. Rail-to-rail input and output operation can be advantageous in mixed-signal systems where signals occupy much of the available supply range. The 400 kHz gain-bandwidth figure supports moderate-frequency gain and buffering, while the four-channel arrangement simplifies routing for quadrature, differential, multi-axis, or repeated measurement functions. Designers should confirm channel-to-channel behavior, output-current capability, and thermal limits in the data sheet. Unique channels still require appropriate grounding, and bypassing should follow the manufacturer's recommended layout to minimize supply-to-output coupling.
Önerilen
Precision Reference and Buffering
The LT1367CS can provide voltage buffering or gain stages around precision references and low-level control signals. Rail-to-rail output capability helps the buffer reproduce command or reference levels with less headroom loss, while four channels allow several references or control outputs to share one package. The 400 kHz gain-bandwidth product is suitable for static and moderate-frequency reference networks. Final suitability depends on input offset, input bias current, output impedance, load-current limits, and noise, none of which are supplied in the verified excerpts. Verify those values in the manufacturer data sheet and account for reference-node loading and temperature drift in the overall error budget.
Önerilen
Low-Frequency Audio and Communication Control
The LT1367CS is applicable to low-frequency audio-control or communication-signal paths requiring four channels and broad input and output range. The 400 kHz gain-bandwidth product is consistent with general-purpose and low-frequency signal work, although it is not positioned as a dedicated high-speed audio or communications amplifier. Rail-to-rail output can improve headroom in dual-supply or asymmetric-rail circuitry. Design verification should include output swing at the actual load, slew rate for large-signal transients, noise for quiet audio paths, and stable operation with the selected feedback network. The exact LT1367CS electrical limits must be consulted before claiming a particular signal-to-noise ratio or distortion performance.

Tasarım Notları
Place the supply bypass capacitor and amplifier input or feedback components close to their associated LT1367CS pins. Keep the 14-lead SO footprint within the manufacturer's recommended copper and solder-mask land pattern, and route the V+ and V- pins with low-impedance traces. Because the verified excerpts do not specify the required capacitor value, do not select the bypass network from generic guidance; use the manufacturer data sheet or reference circuit for the exact value and ESR considerations.
Treat the LT1367CS as a precision but bandwidth-limited amplifier with a verified 400 kHz gain-bandwidth product. Set closed-loop gain and noise-gain requirements conservatively, and calculate the resulting bandwidth before relying on a filter corner or settling specification. For high-impedance inputs, minimize leakage from board contamination and adjacent switching nodes. The actual input bias current and offset voltage must be obtained from the manufacturer data sheet before completing a high-impedance error budget.
Do not assume that every quad 14-pin op amp is a functional drop-in replacement. Rail-to-rail behavior must be checked for both input and output, along with supply range, common-mode limits, output swing under load, stability with the selected feedback network, and electrical grade. The supplied cross-reference data names AD811, OPA2673, and THS3201, but their channel counts and packages are not established as equivalent to the four-channel LT1367CS, so they are not listed as drop-ins here.
Uyumluluk Bilgisi
The verified excerpts do not explicitly state the compliance status of the base LT1367CS. The #PBF ordering code commonly denotes a lead-free finish, but that designation was not independently interpreted as a formal RoHS, REACH, or halogen-free declaration in the supplied data, so all compliance fields remain unknown.
