TLV2464ID - Quad 6V 6.4MHz RRIO Op Amp | Texas Instruments
部品番号: TLV2464ID ✓ 生産中TLV2464ID 概要
An operational amplifier is an analog integrated circuit that amplifies the voltage difference between its two inputs. The TLV2464 belongs to the operational-amplifier hierarchy within analog ICs and combines high gain, common-mode input range, output swing capability, and output drive in a compact quad package. The rail-to-rail input stage supports signals approaching the supply rails, while the rail-to-rail output stage allows the output voltage to swing closer to both rails than a conventional non-RRIO amplifier.
The TLV2464 family is specified for operation from a 6 V supply and provides a gain-bandwidth product of 6.4 MHz. Each channel is designed for low-power operation, with the verified family data indicating approximately 500 uA of supply current per channel. The listed 80 mA output-drive capability supports higher-capacitance loads and faster transitions than a lightly loaded general-purpose amplifier can provide. These features are relevant in filtering, buffering, level translation, and sensor-interface circuits.
The input common-mode voltage range extends beyond the supply rails, increasing usable signal range in low-voltage systems. Rail-to-rail output swing improves signal utilization where conventional amplifier headroom would clip the waveform. Four independent channels reduce component count in multichannel analog front ends, although each amplifier still requires suitable bypassing and stable feedback compensation. The available TLV2464ID package is a surface-mount 14-pin SOIC rated from -40 C to +85 C.
Typical uses include portable instrumentation, low-voltage sensor conditioning, active filters, audio and communication interfaces, control loops, and general-purpose buffering. The 6.4 MHz bandwidth is appropriate for moderate-frequency precision signal paths rather than high-speed video or RF applications. When all four channels do not need identical configurations, unused amplifier inputs should be tied to a defined potential close to the common-mode operating point rather than left floating.
PCB design should place the supply bypass capacitor close to the device and preserve a low-impedance ground return. Decoupling requirements, stability criteria, input/output capacitance limits, and shutdown-pin details must be confirmed in the manufacturer datasheet because those values were not included in the supplied search data. Designers should also verify source and sink output-current limits against the actual load, especially when driving capacitive or nonlinear loads.
This page consolidates the verified manufacturer and distributor information, separates known TLV2464ID characteristics from unavailable parameters, and documents same-brand drop-in options without presenting them as verified cross-brand substitutes. It also provides application guidance, comparison fields, and design cautions that help engineers evaluate this quad amplifier for an existing 14-pin SOIC design as of 2026-10-30.

主な用途
TLV2464ID の用途: 6 件s: Portable Sensor Signal Conditioning, Active Filtering and Audio Signal Conditioning, Industrial Control and Measurement Loops, Low-Voltage Communication Interfaces, Battery-Powered Measurement Equipment, General-Purpose Buffering and Level Shifting.
Portable Sensor Signal Conditioning
TLV2464ID fits portable sensor-conditioning designs requiring several low-power analog channels on a small board. Four amplifiers are integrated into one 14-pin SOIC, while the verified family specifications indicate approximately 500 uA of supply current per channel and a 6 V supply rating. The rail-to-rail input stage is useful when sensor outputs occupy much of the available supply range, and the input common-mode range extends beyond the rails. A practical implementation can use the channels for sensor buffering, gain stages, active filtering, and active-low-pass filters. The 6.4 MHz gain-bandwidth product supplies more closed-loop bandwidth than required for many slow sensors, but the actual noise, offset, bias-current, and common-mode limits must be checked in the manufacturer datasheet before finalizing the gain.
おすすめ
Active Filtering and Audio Signal Conditioning
TLV2464ID is suitable for active filters and moderate-bandwidth audio signal-conditioning stages where four rail-to-rail I/O channels are useful. Its 6.4 MHz gain-bandwidth product provides ample open-loop bandwidth for many low-frequency filter sections and audio paths, while the verified 80 mA output-drive capability can support practical load-driving requirements. Each channel can implement a second-order Sallen-Key or multiple-feedback filter, followed by output buffering. Rail-to-rail output swing helps retain signal amplitude in a 6 V system, but filter performance still depends on the exact gain-bandwidth curve, slew rate, output impedance, and capacitive-load stability data. Audio boards should also account for output-noise specifications and decoupling requirements not present in the supplied search snippets.
おすすめ
Industrial Control and Measurement Loops
TLV2464ID can support low-voltage industrial control and measurement circuits that require four independent amplifier channels. The 6 V supply rating and approximately 500 uA per channel make it relevant to compact control boards, while the 6.4 MHz gain-bandwidth product is suitable for many sensor-to-ADC and feedback-control paths. A four-channel implementation could handle current sensing, threshold amplification, error amplification, and output buffering. The rail-to-rail input stage is advantageous when the sensed signal approaches either supply rail. However, the ZDI listing rates the TLV2464ID from -40 C to +85 C, and the verified data does not state whether the exact device is qualified for harsher automotive or industrial temperature classes. Confirm transient protection, noise immunity, and the complete electrical limits before using it in safety-critical loops.
おすすめ
Low-Voltage Communication Interfaces
TLV2464ID is applicable to low-voltage communication interfaces that require signal conditioning close to the transceiver or connector. The rail-to-rail input stage accepts signals extending beyond the nominal supply rails, and the four-channel package can implement receive filtering, thresholding, level conditioning, and transmit-side monitoring. Its 6.4 MHz gain-bandwidth product is appropriate for many control and data-rate conditions rather than high-speed protocol retiming. The 80 mA output-drive capability provides useful margin for lightly loaded line interfaces, although cable capacitance and long traces may require isolation resistors or additional buffering. Engineer the network for the exact data rate and protocol, and verify common-mode rejection, slew rate, noise, and capacitive stability using the manufacturer datasheet rather than relying only on headline bandwidth.
おすすめ
Battery-Powered Measurement Equipment
TLV2464ID fits battery-powered measurement equipment where several analog channels must operate from limited power and a low-voltage supply. Its verified family rating of approximately 500 uA per channel helps limit amplifier contribution to total system current, while the four-channel SOIC reduces board area and external component count. The rail-to-rail input and output stages improve usable signal range in compact converters and handheld instruments. Engineers can assign channels to sensor input, gain, filtering, and output-drive functions, provided unused inputs are biased to a defined voltage. Because the verified data does not provide shutdown-current values, input bias current, noise density, or open-loop gain, a battery-life calculation must include those parameters from the manufacturer datasheet and should be checked against the complete operating mode.
おすすめ
General-Purpose Buffering and Level Shifting
TLV2464ID works as a quad general-purpose buffer or logic-level interface when source and destination voltages lie within a 6 V system. Rail-to-rail inputs and outputs reduce clipping when signals approach the supply limits, and the verified 6.4 MHz bandwidth permits moderate-speed edge transmission. The four channels can buffer MCU outputs, translate logic levels, isolate sensor outputs from ADC inputs, or amplify small baseband signals. A 6.4 MHz amplifier is normally suitable for control and low-to-moderate-speed digital buffering, but it should not be treated as a universal high-speed digital buffer without checking rise time, slew rate, output impedance, and capacitive-load behavior. The manufacturer datasheet should also be reviewed for input overvoltage, output short-circuit, and shutdown-pin constraints.

設計ノート
Place the supply bypass capacitor immediately adjacent to the device's supply and ground pins, and use a low-impedance ground plane to prevent supply ripple from appearing at the amplifier outputs. Because the exact recommended capacitance and ESR were not supplied in the verified snippets, confirm them in the Texas Instruments TLV2464 datasheet rather than assigning a generic value.
Do not leave unused amplifier inputs floating. Tie each unused non-inverting input to a defined common-mode reference and configure the corresponding inverting input to preserve stable operation. Also verify whether shutdown is active-high or active-low and whether any channel-specific shutdown pin affects only its own amplifier; the supplied product snippets do not expose that pin detail.
Treat the 6.4 MHz figure as a gain-bandwidth product, not as guaranteed closed-loop bandwidth for every gain and stability configuration. Use the manufacturer stability and capacitive-load guidance when driving ADC inputs, long PCB traces, cables, or other reactive loads. Add series isolation if oscilloscope testing reveals ringing, and compare input and output settling requirements with the actual slew rate from the datasheet.
Estimated supply power for all four amplifiers at the verified family rating of 500 uA per channel is approximately 2.0 mA at 6 V, excluding load current and shutdown behavior. This estimate uses 6 V and 4 times 500 uA; it is not a datasheet power-consumption specification. Validate the calculation against shutdown current, output load, and the electrical-characteristics table for the selected temperature grade.
コンプライアンス情報
The supplied verified snippets identify the Texas Instruments TLV2464 and TLV2464ID but do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is marked not applicable because the TLV2464ID is described as a standard general-purpose amplifier and no automotive qualification was supplied.
