TLV2621ID - 11MHz RRO Low-Power Op Amp | Texas Instruments
N.º da peça: TLV2621ID ✓ AtivoTLV2621ID Visão geral
An operational amplifier is an analog signal-conditioning semiconductor that uses differential feedback to amplify or buffer a voltage signal. The TLV2621 belongs to the operational-amplifier hierarchy, where rail-to-rail output means the output voltage can swing close to both supply rails. Within low-voltage power management and analog signal conditioning, this capability supports portable sensing, low-voltage instrumentation, and interface circuits operating from a 5.5 V maximum supply.
The TLV2621 combines an 11 MHz gain-bandwidth product with low quiescent current of 800 uA per channel. Its 9.5 V/us slew rate provides useful response to changing input signals, while the 2.7 V to 5.5 V operating range accommodates low-energy electronic systems. The single-channel configuration conserves board area when only one amplifier is required, and the standard 8-SOIC package supports conventional surface-mount assembly.
The TLV2621 is described by Texas Instruments as a low-power, wide-bandwidth, single-supply operational amplifier with shutdown capability in the product family. Rail-to-rail output behavior is particularly useful in systems whose signal range extends toward the positive supply rail. Designers should still account for input common-mode range, output swing, noise, stability, and load-drive limits when selecting feedback components and defining the usable signal range.
Typical uses include low-voltage sensor interfaces, portable measurement equipment, industrial signal conditioning, battery-powered monitoring, and general-purpose analog amplification. The 11 MHz bandwidth makes the device relevant to higher-bandwidth feedback networks than low-frequency precision amplifiers, while its 800 uA per-channel supply current supports designs where amplifier power consumption is an important system constraint.
Design around the exact 2.7 V to 5.5 V supply range, and verify the required input and output swing for the application. Place input and feedback components close to the device, maintain the decoupling structure recommended by the manufacturer, and use stable compensation for non-inverting gain and capacitive-load conditions. Confirm shutdown behavior and pin functions in the pin-description table before assigning board connections.
This page combines the manufacturer product information, distributor identification, pin-package details, family-level construction options, and practical selection guidance. It also distinguishes verified drop-in candidates from options requiring separate electrical review, helping engineers identify whether TLV2621ID is appropriate for a new design or an existing 8-SOIC layout.

Aplicações típicas
TLV2621ID é adequado para 6 aplicaçãos: Low-Voltage Sensor Signal Conditioning, Portable Battery-Powered Instrumentation, Industrial Control and Monitoring, ADC and Comparator Input Drivers, Audio and Communication Signal Buffers, Power-Sequenced Control and Interface Circuits.
Low-Voltage Sensor Signal Conditioning
The TLV2621ID fits low-voltage sensor front ends because it operates from 2.7 V to 5.5 V, provides rail-to-rail output, and consumes 800 uA per channel. It can amplify or buffer a sensor signal before it reaches an ADC or comparator while conserving power in a 3.3 V system. The 11 MHz gain-bandwidth product provides more bandwidth than a conventional slow precision amplifier, although the source impedance and target signal bandwidth must be considered when selecting the feedback network. Verify the sensor's output range against the amplifier's complete input common-mode specifications before implementation.
Recomendado
Portable Battery-Powered Instrumentation
The TLV2621ID is appropriate for portable instrumentation where a 2.7 V to 5.5 V supply and 800 uA per-channel quiescent current are important constraints. Its single-channel architecture avoids allocating power to an unused amplifier, while rail-to-rail output improves utilization of a low-voltage signal range. The 11 MHz gain-bandwidth product also allows the device to serve wider-band signal paths than a typical micropower precision amplifier. Designers should still calculate the complete system power budget because sensor excitation, references, ADCs, and interface logic may consume more energy than the amplifier itself.
Recomendado
Industrial Control and Monitoring
The TLV2621ID can condition low-level signals in industrial monitoring systems operating from 3.3 V or 5 V rails. Its 11 MHz bandwidth and 9.5 V/us slew rate provide useful dynamic range for controls, diagnostics, and sensor interfaces, while the 800 uA per-channel current support low-power channel designs. Rail-to-rail output allows the amplifier to use more of the available output swing when the downstream circuit accepts signals near the supply rail. Industrial qualification requirements, transient protection, input filtering, and grounding should be evaluated at the system level rather than inferred from the amplifier ordering information.
Recomendado
ADC and Comparator Input Drivers
The TLV2621ID is suitable for driving the input of an ADC or comparator when the system supply is between 2.7 V and 5.5 V. Rail-to-rail output increases usable signal range, while the 11 MHz gain-bandwidth product allows the amplifier to preserve signal amplitude into the sampling or switching node. Source impedance and the ADC sample-and-hold architecture should be checked together because an op amp may require isolation resistance or a dedicated drive capacitor. Place the amplifier output close to the converter input and keep the feedback network away from high-impedance and switching nodes.
Recomendado
Audio and Communication Signal Buffers
The TLV2621ID can buffer low-level signals in compact audio or communication equipment when the design requires more bandwidth than a micropower precision amplifier. Its 11 MHz gain-bandwidth product, 9.5 V/us slew rate, and rail-to-rail output behavior support small-signal amplification within a 2.7 V to 5.5 V supply. Actual signal quality depends on noise, distortion, input common-mode range, and output drive at the operating frequency, which must be checked against the manufacturer electrical characteristics. For high-fidelity audio paths, verify those parameters rather than treating bandwidth alone as a complete performance criterion.
Recomendado
Power-Sequenced Control and Interface Circuits
The TLV2621ID can be used in low-voltage control systems that need a single analog amplifier channel and a compact 8-SOIC footprint. Its rail-to-rail output supports buffering between a sensor, control element, and digital converter, while the 800 uA per-channel current limits amplifier demand when multiple boards or channels are deployed. The family is associated with shutdown capability, so the exact TLV2621ID shutdown and enable-pin behavior must be confirmed in the pin-description table. Use a defined state for the shutdown control rather than relying on an undriven input during power sequencing.

Guia de seleção
Use TLV2621IP when its ordering suffix matches the required temperature or manufacturing profile. Consider TLV2621AIP when its approximately 12 MHz bandwidth provides useful headroom in a wider-band signal path, and consider TLV2622IP when approximately 10 MHz bandwidth is sufficient and a different family member offers a better sourcing fit. Verify pin functions and full electrical limits before replacing the original. For multi-channel or ultra-low-power designs, a different amplifier family may use less board area or less current than a dedicated single-channel device.

Notas de projeto
Keep the IN+, IN−, output, and feedback components close to the TLV2621ID and return the supply ground directly to the device ground pin. Place the supply bypass capacitor beside the power pins, and avoid routing the feedback trace beneath or alongside noisy switching nodes. The 11 MHz bandwidth makes small PCB parasitics more relevant than they would be in a slow precision-amplifier design, particularly around high-impedance inputs and the output node.
Design the power system for a 2.7 V to 5.5 V operating range and include the TLV2621ID's 800 uA per-channel quiescent current in the complete power budget. Rail-to-rail output does not imply zero headroom; use the manufacturer output-swing characteristics to determine the maximum load current at the required output voltage. Account for supply startup, shutdown-state current, and any external load current rather than estimating system demand from quiescent current alone.
Do not assume that rail-to-rail output means rail-to-rail input. Check the input common-mode range, output swing, noise, distortion, and stability requirements at the actual signal frequency and load. When driving a capacitive load, use the stability guidance in the manufacturer datasheet; excessive output capacitance can cause ringing even when the amplifier's gain-bandwidth product is sufficient for the intended closed-loop bandwidth.
Assign the shutdown control only after checking the exact TLV2621ID pin-description table. If the shutdown function is not used, connect it according to the manufacturer's recommendations rather than leaving the control floating. Confirm the pin number against the 8-SOIC drawing and use the package-library pin mapping from the same source, since an incorrect shutdown connection can place the amplifier in an unintended operating state.
