TLV2631ID - 9MHz RRO Op Amp | Texas Instruments
部品番号: TLV2631ID ✓ 生産中TLV2631ID 概要
An operational amplifier is a voltage-feedback amplifier whose open-loop gain, differential inputs, and feedback network determine the behavior of the completed circuit. The TLV2631 belongs to the operational-amplifier hierarchy within analog and linear integrated circuits. Its rail-to-rail output stage permits the output voltage to approach the positive and negative supply limits more closely than a conventional output stage, making it useful when the usable signal range must extend toward the rails.
The TLV2631ID combines a 9 MHz gain-bandwidth product with low channel supply current. Published device information identifies approximately 730 µA of supply current per channel. Rail-to-rail output operation and low power consumption support portable sensing, low-level signal conditioning, and general industrial instrumentation where a single amplifier must provide useful bandwidth without a high quiescent-current budget.
At the circuit level, the TLV2631 is a conventional voltage-feedback operational amplifier, so the closed-loop response is established mainly by external resistors and capacitors rather than an internal switched-capacitor network. Its 9 MHz gain-bandwidth product permits useful closed-loop bandwidth above the audio range, although actual stability, slew behavior, noise, output-current capability, and input-offset performance depend on the complete operating conditions and the manufacturer datasheet.
Typical uses include sensor-signal conditioning, buffer stages, low-level analog amplification, active filtering, and audio or instrumentation interfaces. The single-amplifier configuration is useful when board space is constrained and only one independent amplifier channel is required. The 8-SOIC package also supports conventional surface-mount assembly and hand-soldering during prototype work.
When designing around the TLV2631ID, begin by checking the 5.5 V maximum supply limit, operating-temperature limits, input common-mode range, output swing, noise, offset voltage, and stability requirements in the manufacturer datasheet. Place input, feedback, and decoupling components close to the device, and verify the chosen gain and capacitive loading against the manufacturer’s stability guidance rather than assuming that every feedback value is stable.
This product page combines manufacturer identification, exact orderable-package information, practical application guidance, and a conservative drop-in replacement assessment. It also distinguishes verified same-package candidates from generic functional equivalents, helping engineers evaluate PCB reuse without confusing broad amplifier similarity with true pin-to-pin compatibility.

主な用途
TLV2631ID の用途: 6 件s: Low-Power Sensor Signal Conditioning, Portable Measurement and Monitoring, Active Audio and Communication Filtering, Industrial Instrumentation Interface, Low-Level Analog Buffer, Sensor and Actuator Interface.
Low-Power Sensor Signal Conditioning
The TLV2631ID fits a single-supply sensor-conditioning stage that requires more bandwidth than a basic low-frequency amplifier but does not require multiple amplifier channels. Its 9 MHz gain-bandwidth product provides useful closed-loop bandwidth for many sensor signals, while approximately 730 µA of supply current per channel helps limit power demand. The rail-to-rail output also increases the usable output range near the positive supply limit. The amplifier can be configured as a non-inverting or inverting gain stage around the sensor, with feedback resistors setting the gain and output impedance. Before finalizing the design, verify the sensor’s output range, common-mode limits, offset requirements, noise sensitivity, and the minimum stable gain.
Portable Measurement and Monitoring
The TLV2631ID is appropriate for compact battery-powered measurement modules where one amplifier must process a low-level analog signal without a high quiescent-current budget. Its single-supply architecture simplifies system partitioning, and the 5.5 V maximum rating supports common low-voltage rails used in portable equipment. The 9 MHz gain-bandwidth product is substantially faster than the signal bandwidth of many temperature, pressure, and environmental sensors, allowing useful filtering and conditioning without demanding excessive bandwidth. Designers should still calculate sensor excitation power separately, inspect amplifier offset and bias current, and confirm that the selected operating point remains inside the input common-mode and output-swing limits.
Active Audio and Communication Filtering
TLV2631ID can be used in small active-filter or auxiliary signal-conditioning stages where a 9 MHz gain-bandwidth product and rail-to-rail output are useful. These functions may include microphone preamplification, audio-frequency smoothing, or the active input section of a communication circuit. The single amplifier allows one polarity or channel to be conditioned without committing to a dual package. Component tolerances and the amplifier’s open-loop response will determine the filter’s practical behavior, so simulate the complete network and verify stability with the intended source impedance and load. Keep input and feedback connections short, and confirm the maximum signal amplitude against the rail-to-rail output capability before filtering.
Industrial Instrumentation Interface
The TLV2631ID is suitable for buffering or conditioning the first analog stage of an industrial instrumentation interface when operating from a supply no higher than 5.5 V. A single 8-SOIC package keeps the footprint compact, and the 9 MHz gain-bandwidth product can accommodate many process-control and diagnostic signals while preserving margin for feedback-network roll-off. Rail-to-rail output improves signal swing in low-voltage systems, but input range, offset accuracy, noise, and output-current capability remain critical in precision measurements. Validate the full signal chain at the highest expected input and output levels, and include adequate supply bypassing close to the device to prevent supply disturbance from appearing as signal error.
Low-Level Analog Buffer
When a sensor or divider cannot directly drive the next circuit, the TLV2631ID can provide a voltage buffer with approximately 730 µA of supply current per channel. Voltage-follower operation keeps the nominal closed-loop gain near unity while presenting a much lower output impedance to the following stage. Its 9 MHz gain-bandwidth product leaves useful bandwidth for many dynamic signals, and the single-circuit package avoids unused amplifier channels. The design should still account for input bias current, offset voltage, capacitive loading, output swing, and stability at unity gain. Place the amplifier close to the sensitive source, keep the feedback route short, and confirm that the source impedance remains within the device’s recommended operating conditions.
Sensor and Actuator Interface
The TLV2631ID can bridge a low-voltage sensor front end to a downstream actuator-control stage by providing gain and impedance isolation. Its single supply operation and 5.5 V maximum rating are useful in systems where signal and control voltages share the same low-voltage rail. The 9 MHz gain-bandwidth product allows the amplifier to respond to signal components beyond the audio range, while the rail-to-rail output can improve command swing. Designers must verify output-current capability, output saturation near the rails, and the load presented by the actuator driver. A current-limiting or buffer stage may be required if the load is capacitive or demands more current than the operational amplifier can supply safely.

設計ノート
Place the decoupling capacitor and amplifier input, output, and feedback components close to the 8-SOIC leads. Keep the feedback loop compact because parasitic resistance and capacitance can alter closed-loop response and phase margin. Route sensitive input and feedback traces away from switching-node and high-current supply paths. If the input source has appreciable capacitance, verify stability with the actual source impedance rather than relying only on a simulation with ideal components.
The TLV2631ID has a 5.5 V maximum supply rating, so verify the complete power-source range, including tolerance and transients, before applying power. Place supply and ground connections directly to the relevant pins and provide local high-frequency bypassing in addition to any bulk supply capacitance. If the circuit also powers an actuator or load, separate that transient-producing path from the amplifier supply to prevent rail disturbance from corrupting the conditioned signal.
Choose the closed-loop gain with the 9 MHz gain-bandwidth product in mind, then check the resulting bandwidth against the required signal spectrum. Add filtering where bandwidth is unnecessary, because additional bandwidth can increase noise and susceptibility to interference. For sensor inputs, account for offset, bias current, source impedance, and common-mode range. For capacitive loads, follow the manufacturer’s stability guidance and avoid adding large load capacitance directly to the output without validation.
Do not treat the family name TLV2631 as proof that every package and channel-count option is interchangeable. The TLV2631ID is specifically the single-amplifier 8-SOIC orderable variant. Also do not assume rail-to-rail output means unlimited output swing; the output remains constrained by the supply rails, load, and device specifications. Verify shutdown, common-mode range, thermal limits, and minimum stable gain in the manufacturer datasheet for the exact operating conditions.
