TLV2774CD - Quad 5.1MHz Rail-to-Rail Op Amp | Texas Instruments
부품 번호: TLV2774CD ✓ 활성TLV2774CD 개요
An operational amplifier is a voltage-gain building block that compares an input signal with a feedback network. The TLV2774CD provides four channels in one package, allowing designers to implement filters, amplifiers, level conversions, sensing paths, and signal-conditioning stages while reducing board area. Its rail-to-rail output swing supports operation near the supply rails, while the 10.5 V/μs slew rate improves responsiveness for moderate-frequency waveforms and load-step recovery.
The 5.1 MHz gain-bandwidth product and 10.5 V/μs slew rate are the primary dynamic performance indicators. A wider bandwidth supports higher closed-loop operating frequencies, while slew rate governs how quickly the output can change for larger voltage transitions. The four-channel architecture is particularly useful when several nodes require similar amplification or filtering, but common signal-ground and power-distribution quality remain essential for predictable behavior.
Typical uses include low-frequency sensor conditioning, audio signal paths, instrumentation, current-feedback or voltage-feedback filtering, and general-purpose analog amplification. The 5.5 V maximum supply rating makes the device appropriate for systems operating below that limit. Circuit designers should still verify input and output common-mode limits, output-current capability, capacitive-load behavior, and shutdown-control logic against the manufacturer datasheet before finalizing a design.
The principal design consideration is rail-to-rail behavior at the output. Designers should account for the output swing remaining inside the usable supply range, ensure feedback components preserve intended noise and stability behavior, and place bypassing capacitance close to the power pins. Decoupling helps isolate the amplifier from supply ripple and high-frequency coupling, while keeping sensitive input nodes away from switching-current paths reduces signal-integrity risk.
This page organizes the TLV2774CD’s key specifications, pin-compatible family options, application guidance, and design trade-offs into one engineering-focused reference. It also distinguishes the standard CD ordering code from other TLV2774 qualification and package codes so engineers can select a replacement without changing the 14-pin SOIC board footprint.

일반적인 애플리케이션
TLV2774CD 적합 용도: 6 애플리케이션s: Sensor Signal Conditioning, Industrial Data Acquisition, Audio Preamplifier Stages, Active Filtering and Buffering, Battery-Powered Portable Instruments, Communication Interface Buffering.
Sensor Signal Conditioning
The TLV2774CD fits four-channel sensor conditioning because each amplifier provides 5.1 MHz gain-bandwidth product and 10.5 V/μs slew rate while the family operates from 2.7 V to 5.5 V. Place separate channels around temperature, pressure, or position sensors, using the amplifier to amplify small signals and establish a stable reference-driven output. The 1 mA supply current per channel supports compact instrumentation, while the 14-pin SOIC reduces board area. Verify sensor output range, input bias current, offset, and common-mode compatibility before selecting resistor values.
추천
Industrial Data Acquisition
For industrial acquisition systems, the TLV2774CD provides four amplifiers in one 14-pin SOIC, allowing several analog channels to share the same supply architecture. Its 5.1 MHz bandwidth is suitable for moderate-bandwidth sensing and filtering, while the 10.5 V/μs slew rate supports faster signal transitions than a precision-only amplifier. A practical design can use each channel for input buffering, gain, active filtering, or level conditioning before conversion. Keep sensitive nodes away from relay, motor, and power-converter currents, and verify the amplifier’s operating limits against the selected sensor and ADC inputs.
추천
Audio Preamplifier Stages
The TLV2774CD can serve as a quad low-level audio preamplifier or buffer when the circuit operates within the device’s 2.7 V to 5.5 V supply range. Four rail-to-rail-output channels provide flexible gain and filtering stages without requiring four separate packages. The 10.5 V/μs slew rate can reproduce moderate-level dynamic waveforms, while the 5.1 MHz gain-bandwidth product supports audio-band signal conditioning. Designers should check output swing, load impedance, and distortion characteristics, and should use quiet resistors, a clean reference, and a decoupled supply to avoid degrading the signal.
추천
Active Filtering and Buffering
The four channels of the TLV2774CD are useful for cascaded or parallel active-filter stages, impedance buffering, and gain blocks. A 5.1 MHz gain-bandwidth product allows reasonably wide closed-loop bandwidth, and the 10.5 V/μs slew rate helps preserve large-signal response in moderate-speed filters. Place feedback resistors and capacitors close to the associated pins to minimize parasitic feedback and phase shift. Confirm the required noise gain, capacitive-load tolerance, and output-current capability in the datasheet, especially when driving long cable runs or ADC sampling networks.
추천
Battery-Powered Portable Instruments
The TLV2774CD fits portable measurement instruments because the TLV2774 family operates from 2.7 V and consumes 1 mA per channel. Four amplifier channels can provide compact signal conditioning without dividing the available package count among separate single or dual devices. Use the 5.1 MHz bandwidth for moderate-frequency measurement paths and the 10.5 V/μs slew rate for faster transient handling. Battery systems should also include controlled shutdown behavior, load-switching sequencing, and rail-to-rail output checks so the amplifier remains inside its valid common-mode and output-swing limits.
추천
Communication Interface Buffering
The TLV2774CD can provide receive-side buffering for low-to-moderate-frequency communication and control interfaces when the signal amplitude and bandwidth fit the amplifier’s 2.7 V to 5.5 V operating range. Its rail-to-rail output allows useful signal swing within a low-voltage system, and four channels can handle several related inputs. The 10.5 V/μs slew rate improves large-signal response for moderate-rate links. Keep the loop away from switching regulators and high-current digital outputs, and verify input common-mode range, output drive, noise, and stability before deploying it as an interface replacement.

설계 노트
Place the supply-bypass capacitor immediately beside the device’s power and ground pins, and use the shortest possible ground return. The TLV2774CD supports operation from 2.7 V to 5.5 V, so the supply network must remain within that range during startup and load transients. Keep analog input and feedback traces away from clocks, switching regulators, motor nodes, and high-current return paths to reduce coupled noise.
Do not assume that rail-to-rail output automatically makes every input and output condition valid at the supply limits. Check the manufacturer’s common-mode and output-swing limits for the selected configuration, including the effect of output loading. Also verify shutdown logic and startup sequencing; a pin connection intended for shutdown must not inadvertently place the amplifier outside its valid operating state.
Keep feedback components and filter capacitors close to the relevant amplifier pins, and avoid routing sensitive inputs beneath digital clocks or switching-node copper. The 5.1 MHz gain-bandwidth product and 10.5 V/μs slew rate provide useful dynamic performance, but parasitic capacitance and board routing can affect stability and large-signal behavior. Validate the final board with the intended feedback network, load, source impedance, and supply decoupling.
