TLV2470IP - 6V 2.8MHz RRIO Op Amp with Shutdown | TI
部品番号: TLV2470IP ✗ 生産終了TLV2470IP 概要
An operational amplifier is an analog integrated circuit that uses differential feedback to amplify the difference between two input voltages. The TLV2470 family belongs to the broader hierarchy of op amp -> operational amplifier -> analog IC -> semiconductor. Rail-to-rail input and output operation allows the amplifier to operate near the supply rails, making it useful in battery-powered instrumentation, sensor interfaces, signal conditioning, audio, and industrial control systems.
The principal listed specifications are a 6 V maximum supply voltage, 2.8 MHz gain-bandwidth product, approximately 600 µA per channel supply current, and rail-to-rail input/output capability. The TLV2470 product family also includes a shutdown function, allowing the amplifier to be placed in a low-power state when the system does not require continuous amplification. The exact input offset, output-current, noise, and temperature-range details for the TLV2470IP should be confirmed against the manufacturer datasheet before final design release.
The TLV2470IP is specified as an 8-PDIP, or 8-pin dual in-line package, making it suitable for through-hole prototyping and legacy industrial or instrumentation boards where a surface-mount package is not required. Its single amplifier per package permits flexible allocation of analog channels across a larger system. The 2.8 MHz bandwidth is more than adequate for many sensor, buffer, and general signal-conditioning stages, while the approximately 600 µA per-channel consumption supports power-conscious designs.
Typical uses include low-voltage sensor conditioning, buffered instrumentation inputs, audio signal paths, portable measurement equipment, and industrial control modules. When designing around this amplifier, verify input and output common-mode limits at the selected supply voltage and confirm the required output swing against the load. Account for shutdown-state behavior, input bias currents, noise, and stability when driving capacitive loads.
This page combines the exact manufacturer and distributor identifiers for TLV2470IP with package information, lifecycle context, pricing extraction, cross-reference alternatives, and practical design guidance. Use the manufacturer datasheet as the controlling document for pin assignment, electrical limits, recommended operating conditions, and application-specific design guidance.

主な用途
TLV2470IP の用途: 6 件s: Low-Voltage Sensor Signal Conditioning, Portable Measurement Instrumentation, Industrial Process Control, Audio Signal Buffering, Battery-Powered Sensor Nodes, Data Acquisition Front End.
Low-Voltage Sensor Signal Conditioning
The TLV2470IP is suitable for conditioning low-voltage sensor outputs when the design needs a single amplifier with a 6 V-class supply, 2.8 MHz gain-bandwidth product, and rail-to-rail input/output capability. It can provide gain, filtering, or buffering ahead of an ADC or controller. The approximately 600 µA per-channel supply consumption is useful in battery-operated instrumentation. Confirm the input common-mode range, output swing, offset voltage, and noise against the sensor error budget before production release.
おすすめ
Portable Measurement Instrumentation
The TLV2470IP fits portable measurement equipment where a 6 V-class amplifier can operate from a compact supply and the approximately 600 µA per-channel current helps control power consumption. Its 2.8 MHz gain-bandwidth product supports general-purpose signal conditioning rather than only static voltage measurement. Shutdown can reduce consumption when the measurement channel is inactive. Validate offset, noise, input bias current, and temperature drift to ensure the complete measurement uncertainty remains acceptable.
おすすめ
Industrial Process Control
The TLV2470IP can serve as an interface amplifier in industrial process-control circuits handling sensor or actuator signals near the limits of a low-voltage supply. Rail-to-rail input and output operation provides flexibility when signals approach either rail, while the 2.8 MHz bandwidth is suitable for many control and monitoring signals. Its obsolete lifecycle status makes a current supported alternative preferable for new deployments. Any redesign must account for industrial temperature requirements, noise, isolation boundaries, and long-term availability.
おすすめ
Audio Signal Buffering
The TLV2470IP can buffer a general-purpose audio signal when the source impedance is moderate and the required bandwidth is below the device's 2.8 MHz gain-bandwidth product. Rail-to-rail output capability can be useful in low-voltage signal chains, while shutdown helps manage power in portable audio equipment. Confirm output drive, output-voltage swing, noise density, and capacitive-load stability in the manufacturer datasheet. The obsolete lifecycle designation should also be considered when selecting a component for a long-life production program.
おすすめ
Battery-Powered Sensor Nodes
The approximately 600 µA per-channel consumption and shutdown capability make the TLV2470IP relevant to battery-powered sensor nodes operating from a compact supply. Its single-amplifier 8-PDIP configuration allows several distributed channels to use separate packages, and the 6 V-class operating point suits common low-voltage rails. The design must verify the rail-to-rail behavior over the complete battery discharge range, including output headroom at light load and amplifier behavior during shutdown. For new deployments, compare current supported alternatives.
おすすめ
Data Acquisition Front End
The TLV2470IP can provide the first amplification or buffering stage in a data-acquisition front end when the source is low impedance and the signal bandwidth fits the 2.8 MHz gain-bandwidth product. Its rail-to-rail input and output characteristics help preserve dynamic range in a compact 6 V-class analog system. Place adequate supply bypassing near the device and keep sensitive input routing short to limit pickup. Verify the amplifier's noise and settling behavior against the acquisition bandwidth and sample-rate requirements.

主な差別化要因
- Directly identified replacement candidate with the same 8-PDIP format （vs TLV2471IP)

- Cross-brand replacement path with a documented compatible candidate （vs MCP603-I/P)
設計ノート
Do not treat a family member as an automatic drop-in replacement. Confirm the manufacturer's pin-description table, supply-voltage limits, input common-mode range, output swing, shutdown logic, and electrical limits for the exact ordering code. The TLV2470IP is obsolete, so a replacement should be reviewed against the original design requirements rather than selected only by package and bandwidth.
Estimate the amplifier's contribution to system power using the stated approximately 600 µA per-channel consumption and the actual operating voltage. Estimated: at a 5 V supply, one continuously active channel consumes approximately 3 mA, calculated as 5 V × 600 µA. If the shutdown function is used, confirm the shutdown-state current and ensure that the control signal remains valid throughout startup, reset, and fault conditions.
Use the manufacturer package drawing to reproduce the 0.300 inch, 7.62 mm 8-pin DIP footprint, and verify pin-1 orientation before insertion. Place the device close to the protected signal source, keep input traces short, and provide local supply bypassing near the power pins. For sensitive analog signals, route output and supply paths away from fast-switching nodes and use a grounded guard or shielding strategy where required.
Check closed-loop bandwidth against the highest signal frequency of interest. The TLV2470 family is identified as a 2.8 MHz gain-bandwidth-product amplifier, so higher closed-loop gains reduce available bandwidth. For example, a gain of 10 gives an ideal gain-bandwidth-limited bandwidth of 280 kHz. Confirm settling behavior and capacitive-load stability when driving long cables, sensor inputs, or sampling networks.
