TLV2475ID - 4-Channel 2.8 MHz RAIL-to-RAIL Op Amp | Texas Instruments
N.º de pieza: TLV2475ID ✓ ActivoTLV2475ID Descripción general
An operational amplifier, or op amp, is an analog integrated circuit that amplifies the difference between two input voltages. The TLV2475 is a four-amplifier device, making it useful when a design needs multiple signal-conditioning channels in one package. Its rail-to-rail input and output characteristics support operation close to the supply rails, while the low-power architecture is intended for portable, battery-powered, sensor, and low-voltage signal-chain applications.
Key characteristics include a 2.8 MHz gain-bandwidth product, 600 uA per channel, low input-bias current, and shutdown support. The CMOS construction supports low quiescent current and operation from a 6 V-rated supply environment. The 16-SOIC package provides a conventional leaded footprint that is useful for prototypes, industrial assemblies, and designs requiring through-hole-compatible soldering rather than a very small land pattern.
The TLV2475ID belongs to the TLV247x family of low-power, high-drive operational amplifiers. The family is intended to balance bandwidth and supply current rather than maximize either parameter independently. The 2.8 MHz bandwidth gives useful closed-loop response for general-purpose amplification, filtering, and buffering, while the 600 uA per-channel current supports power-conscious designs. Users should still evaluate output drive, slew rate, noise, and input common-mode behavior against the specific signal and load before finalizing a design.
Typical applications include low-voltage sensor interfaces, portable instrumentation, battery-powered measurement systems, analog signal conditioning, and multichannel filtering. The quad configuration reduces the number of packages and can simplify power distribution when four independent amplifier channels are required. The shutdown pin can also reduce system power when the measurement subsystem is not active.
A key design consideration is ensuring that input and output signals remain within the electrical limits of the selected rail-to-rail implementation. Place bypass capacitors close to the supply pins and route sensitive input and feedback traces away from noisy switching nodes. When using shutdown, verify that the shutdown logic and timing meet the system power-management requirements. For exact pin assignments, limits, timing, and test conditions, consult the manufacturer datasheet.

Aplicaciones típicas
TLV2475ID es adecuado para 6 aplicacións: Low-Voltage Sensor Signal Conditioning, Portable Instrumentation, Battery-Powered Environmental Monitoring, Analog Filtering and Buffering, Industrial Control Signal Conditioning, Audio and Communication Interface Circuits.
Low-Voltage Sensor Signal Conditioning
The TLV2475ID suits multichannel sensor front ends that need low-power amplification close to the sensor. Its rail-to-rail input and output characteristics provide useful signal range flexibility in low-voltage systems, while the 600 uA per-channel specification helps preserve battery life. Four channels can amplify resistive, capacitive, or buffered sensor outputs without requiring four separate amplifier packages. The 2.5 pA input-bias-current value is particularly helpful when the source impedance is high, because it limits input loading. The system designer should still verify the sensor output range, amplifier noise, common-mode limits, and stability with the selected feedback network.
Recomendado
Portable Instrumentation
The TLV2475ID is appropriate for handheld or battery-powered measurement equipment requiring several analog channels at modest bandwidth. Its 2.8 MHz gain-bandwidth product is adequate for general-purpose low-frequency signal acquisition, while 600 uA per channel supports a conservative power budget. The quad architecture reduces board area and simplifies supply routing for instrumentation that processes multiple analog channels. Shutdown can be used during inactive measurement intervals if the surrounding control logic and board design satisfy the family’s shutdown requirements. For precision measurement, verify input offset, noise, drift, and settling performance in the manufacturer datasheet.
Recomendado
Battery-Powered Environmental Monitoring
A quad TLV2475ID can support environmental monitoring nodes that combine several sensor inputs, such as temperature, light, or gas-sensor conditioning. The low 600 uA per-channel supply current helps limit average system energy, and the input-bias-current specification of 2.5 pA reduces loading on high-impedance sensor networks. Rail-to-rail input and output operation can improve usable signal swing in systems powered from low-voltage sources. The amplifier does not replace sensor excitation or protection circuitry, so designers should include appropriate filtering, clamping, and sensor-specific bias networks. Shutdown is useful for duty-cycled monitoring when the device is otherwise inactive.
Recomendado
Analog Filtering and Buffering
The TLV2475ID can implement active filters, sample-and-hold support circuitry, and general-purpose buffers where multiple channels and moderate bandwidth are required. Its 2.8 MHz gain-bandwidth product gives design engineers a defined bandwidth target when selecting closed-loop gain and filter poles. The quad package allows several filter sections to be placed close to a sensor or ADC input, reducing sensitive trace lengths. Component tolerances and amplifier behavior must be considered when designing higher-order filters, and the feedback network should be checked for stability with the intended source and load. The manufacturer datasheet should be used for recommended operating conditions and layout requirements.
Recomendado
Industrial Control Signal Conditioning
The TLV2475ID can condition low-level control signals in industrial equipment where four channels and a conventional 16-SOIC footprint are useful. Its 6 V-rated supply and rail-to-rail input/output characteristics support compact analog sections powered from a low-voltage rail. The 2.8 MHz bandwidth is appropriate for many control-loop signals rather than high-speed data acquisition. Industrial implementations should still include transient protection, grounding and filtering appropriate to the environment, and verify the -40 °C to +125 °C operating-temperature designation for the exact orderable part. The shutdown function can reduce power during inactive operating states.
Recomendado
Audio and Communication Interface Circuits
The TLV2475ID can serve as a general-purpose amplifier in low-level audio or communication interface circuits when the signal bandwidth is modest and low supply current is important. The 600 uA per-channel architecture is compatible with portable or compact communication equipment, while the four-channel configuration can support microphone, headphone, or control-interface signal paths. Actual audio-system suitability depends on output swing, load capability, noise, and distortion requirements that vary with the operating point. Designers should compare the family’s high-drive characteristics with the required load and include appropriate coupling or biasing components. Use the manufacturer datasheet to verify limits before selecting it for precision audio paths.

Notas de diseño
Budget the four active channels at approximately 600 uA each, or 2.4 mA under the stated family condition, before adding load and bias-current effects. Place the supply bypass capacitor close to the device power pins and keep the return path short. If shutdown is used for duty cycling, verify its logic polarity and ensure control signals cannot leave the amplifier in an indeterminate state during power-up.
Route the 16-SOIC footprint according to the manufacturer package drawing and keep input, feedback, and shutdown traces away from high-current switching paths. Connect the bypass network near the supply pins, provide a continuous ground reference, and avoid long traces between the amplifier and its feedback resistors. Confirm pin assignments in the TLV2475 datasheet before finalizing the PCB because the shutdown and channel functions are family-specific.
Do not treat a same-family ordering suffix as automatically interchangeable. Compare TLV2475ID against TLV2475AIDR, TLV2475CDR, and other listed 16-SOIC candidates for temperature grade, qualification, pin behavior, and production status. Also check the output load, input common-mode range, and shutdown timing against the actual operating point before approving a substitution.
Información de cumplimiento
No specific RoHS, REACH, lead-free, halogen-free, or conflict-minerals statement is present in the product references. AEC-Q100 status is not applicable because the TLV2475ID is identified as an industrial temperature-grade amplifier rather than an automotive-qualified variant.
