TLV2620ID - 11MHz RRO Op Amp with Shutdown | Texas Instruments
部品番号: TLV2620ID ✓ 生産中TLV2620ID 概要
An operational amplifier is an analog integrated circuit that amplifies the voltage difference between its differential inputs. It belongs to the broader hierarchy of analog ICs, semiconductor devices, and signal-conditioning components. The TLV2620ID uses rail-to-rail output operation, allowing its output signal to approach the available supply rails under suitable load and output conditions. This characteristic is useful in low-voltage systems where conventional fixed-output amplifiers would waste signal range.
The principal highlighted specifications are an 11 MHz gain-bandwidth product, operation from a single supply with a 5.5 V maximum rating, and rail-to-rail output capability. The product family is also described as a low-power, wide-bandwidth amplifier with shutdown. Its single-channel configuration keeps the component count low in designs requiring one amplified signal path, while the small SOIC package supports conventional surface-mount assembly.
The TLV2620ID combines wide bandwidth with a modest maximum supply voltage, making it appropriate for systems operating from low-voltage rails. Its 11 MHz bandwidth provides more signal-path range than a low-frequency precision amplifier and makes the device suitable for moderate-speed sensing and interface tasks. The shutdown feature can reduce power consumption when the active circuit is not required, although the exact shutdown timing and current values should be confirmed in the manufacturer datasheet.
Typical applications include portable sensor conditioning, low-voltage audio circuits, communications interfaces, industrial measurement systems, and general-purpose buffer stages. The rail-to-rail output can improve usable dynamic range in single-supply systems, while the 11 MHz bandwidth is beneficial when the amplifier must process signals beyond low-frequency instrumentation ranges. Shutdown is useful in portable equipment where power conservation during inactive periods is important.
PCB design should place input and output decoupling close to the appropriate supply pins and keep sensitive input traces away from high-current switching paths. Confirm the complete pin assignment, input common-mode range, output-load limits, and recommended operating conditions in the manufacturer datasheet before finalizing a high-impedance or precision application.

主な用途
TLV2620ID の用途: 6 件s: Portable Sensor Signal Conditioning, Low-Voltage Audio Buffering, Industrial Communications Interface, Battery-Powered Measurement Module, Data Acquisition Front End, General-Purpose Analog Buffer.
Portable Sensor Signal Conditioning
The TLV2620ID fits portable sensor-conditioning stages that operate from a low-voltage single supply and require modest signal bandwidth. Its 11 MHz gain-bandwidth product provides useful speed for sensors with bandwidth beyond the audio range, while rail-to-rail output helps use the available voltage span more effectively. The amplifier can sit between a sensor and an ADC input as a voltage follower or noninverting gain stage. Its CMOS implementation, low-power positioning, and shutdown function also suit battery-powered instruments where the channel may be disabled during idle periods. Confirm input bias current, common-mode limits, and noise against the sensor impedance before finalizing the circuit.
おすすめ
Low-Voltage Audio Buffering
The TLV2620ID is appropriate for low-voltage audio buffering when the design needs more bandwidth than a conventional precision amplifier. Its 11 MHz gain-bandwidth product gives ample closed-loop bandwidth for many audio-band and crossover networks, while rail-to-rail output can increase the usable signal swing in a single-supply circuit. The device may serve as a unity-gain buffer after a mixing stage or as an active gain block within a compact audio module. Shutdown can disable the amplifier when the source is inactive. The manufacturer datasheet should be checked for output swing, capacitive-load stability, noise, and drive capability at the selected gain and load.
おすすめ
Industrial Communications Interface
The TLV2620ID can support low-speed communication and interface amplification in compact industrial systems using a 5.5 V-or-lower supply. The 11 MHz gain-bandwidth product provides margin for conditioning signals well above the baseband frequency, and rail-to-rail output helps retain signal amplitude in low-voltage systems. Place it between a transmitter, receiver, or level-shifting front end and an ADC or logic input when the required common-mode range and bandwidth are confirmed. The shutdown function may support duty-cycled instrumentation. Keep sensitive input routing short, bypass the supply locally, and verify ESD protection and surge requirements at the connector because amplifier bandwidth alone does not establish industrial compliance.
おすすめ
Battery-Powered Measurement Module
The TLV2620ID suits a compact battery-powered measurement module that uses one analog channel and needs predictable low-voltage operation. Texas Instruments describes the TLV2620 family as a low-power, wide-bandwidth, single-supply amplifier family with shutdown, making the device relevant to duty-cycled acquisition systems. The amplifier can buffer a sensor output or amplify a low-level analog signal before digitization, while shutdown provides a mechanism to reduce activity when a measurement is not being made. Rail-to-rail output supports efficient use of the available supply range. Validate quiescent current, shutdown behavior, input bias current, and the sensor’s source impedance in the manufacturer datasheet before calculating the overall power budget.
おすすめ
Data Acquisition Front End
The TLV2620ID is useful as an analog front-end amplifier ahead of an ADC in a compact data-acquisition design. Its 11 MHz gain-bandwidth product permits gain selection that preserves bandwidth for typical sensor and sampling signals, while rail-to-rail output can improve utilization of a low-voltage ADC input range. The shutdown feature can be coordinated with a duty-cycled converter to keep the analog path inactive between conversions. Use short feedback traces, maintain stable feedback-node capacitance, and place bypass capacitance adjacent to the supply pins. The exact input common-mode range, output swing, settling behavior, and noise must be checked against the ADC acquisition requirements before release.
おすすめ
General-Purpose Analog Buffer
The TLV2620ID provides a compact general-purpose buffer for low-voltage analog systems that need more bandwidth than a slow precision amplifier. Its 11 MHz gain-bandwidth product is suitable for unity-gain buffering of moderate-bandwidth signals, and the rail-to-rail output can preserve amplitude margin in single-supply designs. The device may isolate a higher-impedance source from an ADC, filter a small sensor signal, or provide gain before a downstream converter. Shutdown is useful when the buffered channel can be disabled. Validate capacitive-load behavior, output-current capability, and stability because the correct compensation and load arrangement depend on the source impedance and external network connected to the amplifier pins.

設計ノート
Place the supply-bypass capacitor adjacent to the device power and ground pins, and connect it through short, low-inductance traces. The TLV2620ID has an 11 MHz gain-bandwidth product, so supply-disturbance coupling and long return paths can affect the signal more readily than they would in a low-bandwidth precision amplifier. Keep the feedback loop compact, particularly for higher closed-loop gain, and avoid routing input and output traces in parallel.
Do not treat the TLV2620ID, TLV2620IDBVR, and TLV2620IDRG4 ordering codes as mechanically interchangeable. The target and the SOT-23-6 option use different PCB footprints, while suffix codes can also communicate packing or manufacturing attributes. Before releasing a PCB revision, compare the complete orderable MPN, package drawing, pin table, temperature range, and quality status. A software BOM change is not sufficient for a mechanical substitution.
Check the source impedance, feedback network, load capacitance, and intended closed-loop gain against the manufacturer’s stability and output-drive guidance. A unity-gain buffer generally presents different stability behavior from a high-gain amplifier with a large feedback impedance. Add an isolation resistor near the output when driving capacitive loads, and use a low-value feedback capacitor when additional high-frequency noise filtering is needed without sacrificing the required signal bandwidth.
Coordinate the shutdown-control signal with the system power sequence. The TLV2620ID includes shutdown, which can reduce activity in a portable system, but the power architecture must prevent back-powering through signal pins or other connected circuits. Confirm the shutdown logic level, timing, input-state behavior, and current in the manufacturer datasheet. Ensure that inputs remain within their permitted voltage range while the supply is off or transitioning.
コンプライアンス情報
Compliance status must be confirmed from the manufacturer product page, ordering information, and material declaration for the exact TLV2620ID orderable code.
