TLV2774IN - 5.1 MHz Quad Rail-to-Rail Op Amp | Texas Instruments
部品番号: TLV2774IN ✓ 生産中TLV2774IN 概要
An operational amplifier is a voltage-gain amplifier that compares its input voltage with a feedback-determined reference. When used in a closed-loop configuration, negative feedback causes the output to approach the ideal target voltage. The quad format integrates four amplifiers in one package, reducing board area in designs that require multiple gain, buffering, filtering, or signal-conditioning channels.
The TLV2774IN combines a 5.1 MHz gain-bandwidth product with 10.5 V/µs slew rate. These characteristics make it appropriate for higher-bandwidth signal paths than general-purpose low-power amplifiers. Its rail-to-rail output allows the output voltage to approach the positive and negative supply limits, improving usable signal range in low-voltage systems. Each channel consumes 1 mA of supply current according to the family documentation.
The CMOS implementation supports low-voltage operation from 2.7 V to 5.5 V while providing high slew rate and output drive. Good DC precision is particularly useful in instrumentation, sensor-conditioning, and feedback-control circuits where offset and bias-related errors can affect system accuracy. The family also includes shutdown functionality, which can reduce supply demand when an analog subsystem is not needed.
Typical applications include low-voltage sensor interfaces, current-to-voltage conversion, active filtering, audio and communication signal conditioning, industrial control loops, and portable instrumentation. Multiple amplifiers can implement complete analog front ends without requiring four separate packages. Designers should also consider output loading, stability, noise, and the effect of the chosen feedback network when operating at higher frequencies.
For new layouts, place bypass capacitors close to the supply pins and keep feedback paths compact to reduce parasitic feedback. Keep high-speed or high-current output loops physically separate from sensitive amplifier inputs. Verify the input common-mode range, output swing, load capability, and shutdown behavior against the manufacturer datasheet before applying the device outside its intended operating conditions.
This page combines the manufacturer’s amplifier specifications with package information, application guidance, drop-in alternatives, and practical design notes. It is intended to help engineers identify whether the TLV2774IN’s combination of quad integration, 5.1 MHz bandwidth, 10.5 V/µs slew rate, and low-voltage CMOS operation fits a particular analog signal chain.

主な用途
TLV2774IN の用途: 6 件s: Low-Voltage Sensor Signal Conditioning, Active Audio Signal Conditioning, Industrial Control and Feedback Loops, Portable Measurement and Instrumentation, Communications Interface Conditioning, Current-to-Voltage Conversion.
Low-Voltage Sensor Signal Conditioning
The TLV2774IN fits sensor-conditioning front ends that require several amplifiers and a supply as low as 2.7 V. Its 5.1 MHz gain-bandwidth product is ample for conditioning many moderate-bandwidth sensor outputs, while rail-to-rail output operation preserves signal headroom in low-voltage systems. Multiple channels can provide input buffering, gain, filtering, and offset stages without using four packages. The 10.5 V/µs slew rate also supports faster edge rates than a basic precision amplifier. Design the feedback network around the actual source impedance and sensor bandwidth, and verify that the input common-mode range covers the sensor’s full output excursion.
おすすめ
Active Audio Signal Conditioning
The TLV2774IN can implement multiple audio-buffer and filtering stages in compact low-voltage equipment. Its 10.5 V/µs slew rate provides the transient response needed for larger audio signals, while the 5.1 MHz gain-bandwidth product comfortably covers a broad range of audio-band networks. Rail-to-rail output operation can increase usable output swing on 2.7 V to 5.5 V supplies. Four channels allow volume-control, summing, and equalizer functions to share one package. Headphone or speaker loading still requires a separate output stage if the load exceeds the amplifier’s drive capability, and output stability should be checked with the actual filter and load.
おすすめ
Industrial Control and Feedback Loops
The TLV2774IN supports low-voltage industrial control circuits that need several high-speed analog channels on the same board. Its 5.1 MHz gain-bandwidth product and 10.5 V/µs slew rate allow the amplifier to respond to control-loop signals without the slow edge rates of a general-purpose precision part. The quad package can implement error amplifiers, sensor amplifiers, filters, and output drivers. Because industrial environments can introduce electrical noise and temperature variation, the design should use stable feedback components, maintain short high-impedance input routes, and confirm the exact suffix temperature rating before deployment.
おすすめ
Portable Measurement and Instrumentation
The TLV2774IN is appropriate for portable instrumentation where four analog channels, a 2.7 V minimum supply, and modest power use are important. At 1 mA of supply current per channel, the family can consolidate signal-conditioning stages in battery-powered equipment. The 5.1 MHz bandwidth is suitable for many transducer, data-acquisition, and calibration paths, while rail-to-rail output improves signal range in compact systems. For precision measurements, include offset, noise, bias-current, and settling behavior in the system error budget rather than relying only on bandwidth. Select passive components with suitable tolerances and thermal coefficients.
おすすめ
Communications Interface Conditioning
The TLV2774IN can serve as a receive-side amplifier, comparator, level-conditioning stage, or analog filter in low-voltage communication equipment. Its 10.5 V/µs slew rate helps preserve fast signal transitions, and the 5.1 MHz gain-bandwidth product is useful when conditioning signals above the baseband range. Four channels allow one package to handle several related analog functions. Keep input and output routing compact and separate capacitive return currents from sensitive traces. Interface bandwidth, source impedance, and permissible input swing must be evaluated so the amplifier does not limit the communication link or introduce instability into the feedback network.
おすすめ
Current-to-Voltage Conversion
The TLV2774IN can form the transimpedance stage in a photodiode, oxygen sensor, or other current-producing sensor interface. The 5.1 MHz gain-bandwidth product supports faster feedback operation than a slow precision amplifier, while the 10.5 V/µs slew rate improves large-signal response. Other channels can provide post-amplification, filtering, and reference buffering. Compensation depends on sensor capacitance, feedback resistance, and the desired settling behavior, so the transimpedance network should be evaluated for stability rather than sized from bandwidth alone. Use short, guarded feedback traces and account for input-capitance effects in the layout.

設計ノート
Place the power-bypass capacitor immediately beside the package supply pins and connect it with the shortest practical ground path. Keep amplifier inputs, feedback components, and reference nodes away from traces carrying output current or switching-node currents. A compact analog layout matters more at higher frequencies because parasitic capacitance inside the feedback loop can reduce stability margin.
Design feedback networks for the intended closed-loop bandwidth rather than treating the 5.1 MHz gain-bandwidth product as usable signal bandwidth in every configuration. Noise gain, source impedance, and load capacitance determine stability. For high-impedance sources, minimize input capacitance and guard sensitive nodes; for capacitive loads, add the isolation resistor or isolation stage recommended by the amplifier manufacturer.
Do not assume that rail-to-rail output means the output can reach either supply rail under every load. Check output swing, load current, and input common-mode limits at the intended 2.7 V to 5.5 V operating points. Likewise, the 10.5 V/µs slew rate describes large-signal capability, not guaranteed settling accuracy in a precision measurement path.
Estimated: four channels at 1 mA each consume approximately 4 mA from the supply, excluding output-current contribution and bias-dependent variation. Calculate total supply demand using the actual output waveform and load. Keep the shunt path from bypass capacitors to ground short so switching and transient currents do not share a noisy return route with analog signal references.
