TLV272IP 概述
An operational amplifier is an analog integrated circuit that uses high-gain differential feedback to amplify voltage signals. The TLV272IP belongs to the operational-amplifier hierarchy and is appropriate for sensor interfaces, buffer stages, filters, audio paths and general-purpose analog signal chains. Its rail-to-rail output is useful when the amplifier must approach the positive or negative supply rail while retaining a defined output voltage.
The main performance features are 3 MHz gain-bandwidth product, 2.4 V/us slew rate, 550 uA/channel supply current and 39 nV/Hz input noise voltage. The verified family information also specifies operation from 2.7 V to 16 V, with commercial and extended-temperature options in the broader TLV27x family. Because the TLV272IP is a dual device, one package can support two independent analog channels.
The PDIP package is through-hole and therefore useful for prototypes, educational designs, repair assemblies and applications where leaded parts are preferred over surface-mount packages. Its 8-pin arrangement matches the dual-op-amp pinout convention, but the exact pin names and electrical limits must be confirmed against the manufacturer datasheet before final PCB release. The verified sources identify the TLV272IP as a dual rail-to-rail-output operational amplifier in an 8-PDIP package.
Typical uses include low-voltage sensor buffering, portable instrumentation, audio preamplification, active filtering and industrial control signal conditioning. The 3 MHz bandwidth provides more signal bandwidth than a strictly low-frequency precision amplifier, while the 550 uA/channel current supports battery-conscious designs. The tradeoff is that the PDIP footprint is larger and less compact than an equivalent surface-mount package.
For PCB design, place input and output components close to the relevant pins and maintain a common ground reference. Decoupling capacitors should be placed at the power pins to control supply impedance and high-frequency noise. Confirm stability, input common-mode range, output-load limits and supply current in the final circuit rather than relying only on the headline bandwidth and slew-rate figures.
This product record combines verified manufacturer and distributor information with explicitly marked data gaps, practical application guidance and sourcing-oriented search terms. It is intended to help engineers identify the correct package, assess whether TLV272IP fits a signal-chain requirement and locate the manufacturer datasheet before committing to a design.

典型应用
TLV272IP 适用于 6 应用s: Low-Voltage Sensor Buffering, Portable Instrumentation, Audio Preamplification, Active Filtering, Industrial Control Signal Conditioning, Battery-Powered Analog Interface.
Low-Voltage Sensor Buffering
The TLV272IP fits sensor signal conditioning where a low-noise supply and compact dual-channel implementation are useful. Its verified 2.7 V minimum supply, 550 uA/channel current and rail-to-rail output help preserve signal range on low-voltage systems. Place one channel near the sensor output as a voltage follower and use the second channel for filtering or level conditioning. Verify the actual input common-mode range, offset and load limits against the manufacturer datasheet before production.
推荐
Portable Instrumentation
TLV272IP is suitable for portable instrumentation because it combines two amplifiers, 3 MHz bandwidth and 550 uA/channel supply current. A dual package reduces the number of active devices in a compact analog front end, while the 2.4 V/us slew rate supports signals beyond very-low-frequency precision applications. Designers should account for the through-hole PDIP footprint and confirm offset, bias-current and output-swing limits for the selected gain and load.
推荐
Audio Preamplification
The TLV272IP can serve in audio preamplifier and line-stage circuits when rail-to-rail output is important at low supply voltage. Its 3 MHz gain-bandwidth product and 2.4 V/us slew rate provide more bandwidth than a slow precision amplifier, while dual channels allow stereo or balanced signal paths. The designer should check output drive into the intended load and assess noise, distortion and stability in the actual gain configuration before selecting it for high-fidelity audio.
推荐
Active Filtering
TLV272IP is appropriate for active-filter implementations that need modest-to-wide signal bandwidth and low supply current. Each channel can form a first- or second-order filter section when the target closed-loop bandwidth and phase margin are compatible with the 3 MHz gain-bandwidth product. Place feedback components close to the relevant pins, maintain short ground returns and bypass the supply rails. Verify component tolerances and filter stability over the required temperature range.
推荐
Industrial Control Signal Conditioning
The TLV272IP can condition low-level industrial control signals when the system operates from a supply within the verified 2.7 V to 16 V range. The dual channel arrangement supports signal conditioning and output buffering in one package, and the -40 C to +125 C family specification provides a broad temperature range. Confirm whether the input common-mode range covers the actual sensor node and verify industrial qualification requirements for the specific ordering option before release.
推荐
Battery-Powered Analog Interface
TLV272IP is a reasonable candidate for battery-powered analog interfaces because the verified supply current is 550 uA per channel and operation starts at 2.7 V. Rail-to-rail output can reduce signal clipping when the available voltage headroom is limited, especially in single-supply systems. A supply bypass capacitor should be placed close to the power pins, and the complete battery range should be checked for dropout, output swing and load-current compliance.

关键差异点
- Dual amplifier in one 8-pin PDIP package （对比 TLC27M2ACPE4)
- 3 MHz bandwidth with rail-to-rail output （对比 TLC27M2ACP)
- Low supply current for a dual amplifier （对比 TLC272AIP)
- Single-supply operation from 2.7 V （对比 OPA2227PA)
设计说明
Power the TLV272IP only within the verified 2.7 V to 16 V total supply range. Place a local bypass capacitor close to the supply pins and keep the return path short so switching noise does not appear in the analog signal. Because the device draws approximately 550 uA per channel in the verified family data, estimate the complete current as two channels times the actual channel current before sizing the supply.
Use a compact layout with input, feedback and output paths kept short, especially around high-gain or filtering configurations. Connect the two amplifier channels independently unless the circuit intentionally uses cross-coupled feedback. Verify the numbered 8-pin PDIP pinout from the exact manufacturer datasheet before routing because the provided verified excerpts do not include complete pin assignments.
Do not assume rail-to-rail output means rail-to-rail input common mode, and do not assume the 3 MHz gain-bandwidth product is the closed-loop bandwidth at every gain. Check the input range, output swing under load, stability, offset and noise in the manufacturer datasheet. For a single 5 V supply, confirm that the signal and load remain within the usable output range rather than relying on the nominal supply rating alone.
合规信息
The verified search excerpts do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free or conflict-minerals status. AEC-Q100 is not applicable because the TLV272IP listing is a general-purpose amplifier, not an explicitly automotive-qualified ordering option.
