TLV271IP 概要
An operational amplifier is a voltage-controlled voltage-source device used to amplify the difference between two input voltages. In a practical signal chain, it can provide gain, impedance buffering, filtering, level shifting, or active feedback control. The TLV271 family is positioned as a low-power, general-purpose amplifier family for applications that require more bandwidth than very-low-power micropower parts while keeping supply current modest. The TLV271IP provides one amplifier per package.
The verified manufacturer and distributor information identifies a 3 MHz bandwidth, 2.4 V/µs typical slew rate, 2.4 V minimum supply voltage, 16 V maximum supply voltage, 550 µA typical supply current, and input noise voltage of 39 nV/√Hz. The amplifier has rail-to-rail output operation, while the supplied data identifies a 39 nV/√Hz input noise voltage and an input bias current specification reaching 1 pA. These characteristics make it appropriate for sensor interfaces, analog measurement chains, buffering, and low-power embedded systems.
Typical circuit use places the TLV271IP in non-inverting or inverting amplifier configurations, voltage followers, transimpedance front ends, and active filters. Because the output is rail-to-rail, the device can maximize usable signal range in low-voltage systems, although the exact output swing depends on load current and supply voltage. Its 3 MHz bandwidth enables higher-frequency signal paths than a slow precision amplifier, while the 550 µA supply current helps control power use in battery-powered or space-constrained equipment.
The principal design consideration is supply and signal-headroom planning. The input common-mode range, output swing, load capability, noise performance, and stability requirements should be checked against the manufacturer datasheet for the selected supply and temperature conditions. Decoupling capacitors should be placed close to the power pins, and unused input pins must be handled according to the datasheet recommendations. The provided web data identifies the device as a CMOS amplifier in an 8-PDIP package, but detailed electrical limits and complete pin functions are not included in the supplied records.
This product data combines the verified Texas Instruments and distributor listings, identifies the TLV271IP as a 16 V, 3 MHz, rail-to-rail-output single op amp, and separates documented specifications from parameters that require confirmation in the full manufacturer datasheet. It also records commercially relevant package and application information for engineers comparing low-power operational amplifiers.
The TLV271IP is positioned for instrumentation, buffer, and general-purpose analog designs where a single amplifier, low-power operation, and rail-to-rail output are useful. It can serve as a building block in sensor signal conditioning, portable measurement equipment, industrial control interfaces, and embedded analog signal paths.

主な用途
TLV271IP の用途: 7 件s: Low-Power Sensor Signal Conditioning, Portable Instrumentation Buffer, Battery-Powered Analog Signal Path, Active Filter and Small-Signal Conditioning, Audio and Communication Interface Buffer, Industrial Control and Data Acquisition, General-Power Embedded Analog Front End.
Low-Power Sensor Signal Conditioning
The TLV271IP fits sensor front ends that need measurable bandwidth without the current demand of a higher-power amplifier. Its 550 µA typical supply current per channel helps limit power use in portable equipment, while the 3 MHz gain-bandwidth product and 2.4 V/µs typical slew rate support moderate-frequency sensor signals. Place the amplifier in a non-inverting, inverting, or voltage-follower stage and verify the input common-mode range, offset voltage, noise, and stability requirements in the full datasheet for the selected sensor impedance.
おすすめ
Portable Instrumentation Buffer
The TLV271IP is appropriate for buffering a sensor or converter before an ADC in portable measurement equipment. Its 1 pA specified input bias current can help preserve high-impedance source measurements, while the 39 nV/√Hz input noise figure provides a documented noise starting point. The rail-to-rail output can reduce signal headroom loss in a 2.4 V minimum-supply design, but output loading and the exact input range must be validated from the manufacturer datasheet.
おすすめ
Battery-Powered Analog Signal Path
The TLV271IP can serve as the active element in a battery-powered analog signal path when 3 MHz bandwidth is useful but full micropower operation is not required. Its 550 µA typical supply current is documented, and the rail-to-rail output helps use a low-voltage supply more effectively than a fixed-output amplifier. Design checks should include total quiescent current, load-dependent current, supply rejection, output swing, and the possible need for a shutdown arrangement at the system level.
おすすめ
Active Filter and Small-Signal Conditioning
The TLV271IP is suitable for active-filter and small-signal conditioning stages that require a bandwidth higher than a very slow micropower op amp. The 3 MHz gain-bandwidth product and 2.4 V/µs typical slew rate give designers useful speed margin for moderate-frequency filter sections. Component values should be calculated from the desired pole and gain, then checked for stability, parasitic capacitance, output loading, and the exact common-mode and output-swing limits.
おすすめ
Audio and Communication Interface Buffer
The TLV271IP can be evaluated for audio or communication interface buffering when its 3 MHz bandwidth and 2.4 V/µs slew rate are adequate for the signal path. The rail-to-rail output improves utilization of a low-voltage supply, and the 550 µA typical supply current may help in portable audio or control equipment. Designers should compare noise, output drive, distortion, input range, and stability against the exact application rather than relying on bandwidth alone.
おすすめ
Industrial Control and Data Acquisition
The TLV271IP can be used in industrial control and data-acquisition modules as a general-purpose low-power amplifier around sensor, comparator, or conversion stages. Its 2.4 V to 16 V supply capability permits operation across compact low-voltage and higher-voltage system rails, subject to detailed operating-condition limits. For factory equipment, check temperature-grade requirements, noise immunity, offset drift, input protection, and grounding before releasing a production design.
おすすめ
General-Power Embedded Analog Front End
The TLV271IP is suitable as a general-purpose amplifier in embedded analog front ends where one amplifier, modest supply current, and rail-to-rail output are preferable to a larger or more specialized device. Its documented 3 MHz bandwidth supports many low- and moderate-frequency embedded signal paths. The design must account for the exact package pinout, input bias current, output loading, decoupling, temperature grade, and any required protection at the connector or sensor input.

主な差別化要因

- 8-PDIP single-amplifier format （vs TLV271CP)
設計ノート
The verified 550 µA per-channel supply current is the starting point for battery-life calculations, but total current also depends on the selected package grade, load, supply voltage, and output activity. Verify the quiescent and load-current curves in the manufacturer datasheet before sizing a power budget. Add local supply bypassing at the device pins and keep return-current paths short so switching and digital currents do not share a noisy amplifier return path.
Use the documented 3 MHz gain-bandwidth product and 2.4 V/µs typical slew rate to assess whether the selected gain and signal frequency leave adequate bandwidth and phase margin. For high-impedance sources, account for the 1 pA specified input bias current and source capacitance; excessive capacitance can create stability problems even when the amplifier is intended for a unity-gain buffer. Confirm the recommended feedback network and output-load limits in the full datasheet.
Place input, output, and bypass components close to their associated TLV271IP pins and route high-impedance input traces away from power converters, clocks, and digital switching nodes. Because the package is an 8-PDIP rather than a compact surface-mount option, preserve the manufacturer's recommended lead spacing and keep analog and return paths physically separated. The supplied records do not include a verified pinout, so do not finalize board connections from this listing alone.
コンプライアンス情報
The verified records do not provide RoHS, REACH, lead-free, halogen-free, or conflict-minerals declarations. TLV271IP is an operational amplifier rather than an automotive-qualified AEC-Q100 device in the supplied records.
