TLV274CD 概要
An operational amplifier is an analog integrated circuit that uses high open-loop gain to amplify voltage differences between its input terminals. The TLV274 belongs to the operational-amplifier, analog-amplifier, and signal-conditioning IC hierarchy. Its four amplifiers in one package make it suitable for multi-channel systems, while rail-to-rail output helps the output approach the supply rails and improves dynamic range in low-voltage designs.
The verified data lists 3 MHz bandwidth, 2.4 V/µs slew rate, 16 V maximum supply voltage, 550 µA per channel, and 550 µA/channel input-noise-related information. The wide supply range supports portable, industrial, test, and measurement systems. The low power per channel is useful when four amplifiers must operate continuously, while the 3 MHz bandwidth is more appropriate for general-purpose signal paths than precision low-frequency instrumentation alone.
The TLV274CD uses a 14-pin SOIC package and is offered through distributors including DigiKey, Mouser, LCSC, and Octopart. The verified DigiKey result identifies it as a standard general-purpose amplifier with four circuits and rail-to-rail output. Because the available data does not provide complete pin names, exact electrical limits, or validated drop-in alternatives, those details are marked as needed rather than guessed.
Typical uses include low-frequency sensor interfaces, buffered analog measurement chains, current or voltage signal conditioning, audio preamplifier stages, and general embedded control systems. Keep the input common-mode range, output swing, load, supply voltage, and stability requirements within the manufacturer datasheet limits, and account for input bias current, noise, and capacitive loading.
For PCB design, place the bypass capacitor close to the supply pins and keep analog input and output routing short. Avoid excessive capacitive loading at the output and verify stability with the selected feedback network. This page combines verified manufacturer and distributor information with practical design guidance; confirm final electrical and mechanical details against the official TI datasheet before release.

主な用途
TLV274CD の用途: 6 件s: Sensor Signal Conditioning, Low-Power Data Acquisition, Audio Preamplifier, Industrial Control Interface, Portable Instrumentation, General Buffering and Level Conditioning.
Sensor Signal Conditioning
The TLV274CD is suitable for conditioning low-frequency outputs from sensors because it combines four channels, 3 MHz bandwidth, and 550 µA supply current per channel in one 14-pin SOIC. Place the amplifier near the sensor interface to minimize noise pickup, and use a resistor-defined gain stage that remains within the input common-mode and output-swing limits. The 2.4 V/µs slew rate is useful when the conditioned waveform needs more response than a very-low-bandwidth precision amplifier, while low power helps portable or distributed sensor systems.
おすすめ
Low-Power Data Acquisition
The four-channel TLV274CD can reduce the number of amplifier packages in a compact data-acquisition front end. Its 2.7 V to 16 V supply range supports multiple system rails, and the 3 MHz bandwidth provides margin for general-purpose analog signals rather than only static measurements. Use one channel per input where channel-to-channel matching and local routing matter, place supply bypassing near the package, and check settling time against the required sample rate before using the part in precision instrumentation.
おすすめ
Audio Preamplifier
The TLV274CD can serve as a general-purpose audio preamplifier stage when the design needs multiple low-power channels and moderate bandwidth. The 3 MHz gain-bandwidth and 2.4 V/µs slew rate provide response for many small-signal audio paths, while the 550 µA per-channel supply current is suitable for compact systems. Confirm output swing into the next stage, configure input and feedback resistors for the intended gain, and test distortion because the verified data does not specify a complete output-capability or distortion table.
おすすめ
Industrial Control Interface
The TLV274CD is applicable to industrial control boards where four analog signals must be amplified close to an ADC or comparator. Its -40 °C to +125 °C verified temperature range and 2.7 V to 16 V supply span support a range of embedded systems, although the exact CD-grade limits must be confirmed in the official datasheet. Keep high-current switching nodes away from the input traces, use a solid ground reference, and validate transient immunity and settling at the system level.
おすすめ
Portable Instrumentation
The TLV274CD fits portable measurement equipment where four amplifier channels are needed without the power budget of a high-current precision amplifier family. Its 550 µA-per-channel supply current is the primary power advantage, while the 3 MHz bandwidth is suitable for signals beyond DC and the 2.4 V/µs slew rate helps preserve waveform shape. Estimate battery impact from the actual supply voltage and measured operating current, and ensure the chosen ADC or sensor has compatible input-range requirements.
おすすめ
General Buffering and Level Conditioning
The TLV274CD can buffer sources before downstream analog circuitry when a design requires rail-to-rail output and moderate speed. Its 14-pin SOIC package consolidates four independent amplifiers, reducing component count in a multi-node analog board. Use a unity-gain buffer configuration only after checking output stability and capacitive-load limits; otherwise use a resistor feedback network that controls noise gain. The 2.7 V to 16 V supply range makes it adaptable to different system rails, subject to the datasheet’s absolute-maximum limits.

主な差別化要因

- Rail-to-rail output capability （vs TLV9154)
設計ノート
The verified 550 µA-per-channel current is the starting point for battery and thermal planning, but measure the actual operating current in the final circuit because output loading, supply voltage, and input conditions affect it. For four channels, the nominal current is approximately 2.2 mA before package-level effects. Calculate estimated dissipation as P = VDD × IDD and provide local supply bypassing according to the manufacturer layout guidance.
Place the supply bypass capacitor close to the amplifier supply pins and keep the ground return compact. Route each sensitive input away from switching nodes, clocks, and high-current outputs. Because the TLV274CD contains four channels in one package, use short, symmetrical routes when channel matching matters and avoid sharing long return paths between analog and digital portions of the board.
Rail-to-rail output does not automatically mean rail-to-rail input operation. Before using the amplifier near 0 V or the positive supply rail, verify the input common-mode range, output swing, and absolute-maximum limits in the official TI datasheet. Also check capacitive loading and feedback compensation before adding a large capacitive load directly to an output.
Use resistor feedback values that keep noise gain appropriate for the intended bandwidth and load. If driving an ADC, buffer or filter the amplifier output according to the ADC’s input-capacitance and sampling requirements. The verified 3 MHz bandwidth and 2.4 V/µs slew rate are useful starting points, but they do not replace settling-time and distortion checks for a specific signal chain.
