TLV2464CN - Quad 6V RRIO Op Amp | Texas Instruments
料号： TLV2464CN ✓ 量产中TLV2464CN 概述
A rail-to-rail input/output operational amplifier is a voltage-feedback amplifier whose input common-mode range and output swing can approach its supply rails. The TLV2464 family uses this capability to process signals near the limits of a low-voltage supply. Its role within the hierarchy is operational amplifier → rail-to-rail amplifier → low-power analog signal-conditioning IC, making it useful where amplifier channels must operate from limited supply voltage and headroom is constrained.
Four amplifiers are integrated into one TLV2464CN package, reducing the number of packages required for multichannel analog designs. The 6.4 MHz gain-bandwidth product supports higher-frequency signal paths than a conventional low-power slow-slew-rate amplifier. Rail-to-rail input operation helps preserve signal integrity when common-mode input levels approach either supply rail, while rail-to-rail output operation increases usable output range at low supply voltages.
The approximately 500 µA per-channel supply current and 80 mA output-drive capability provide a practical balance between power efficiency and drive capability. The 80 mA figure is relevant when the amplifier must charge external capacitive loads, drive ADC input networks, or operate with resistive loading. Actual usable bandwidth and output amplitude depend on closed-loop gain, load impedance, output voltage, and the device’s stability configuration.
Typical uses include portable instrumentation, sensor-signal conditioning, battery-powered measurement systems, low-voltage analog front ends, communications equipment, and general-purpose buffering. Multiple channels can process related signals, such as sensor outputs, transducer feedback, analog monitoring nodes, or small-signal conditioning stages without requiring four separate amplifier packages.
When designing around the TLV2464CN, verify the complete datasheet for input bias current, offset voltage, input protection behavior, output swing, and stability before fixing capacitor values or gain settings. Preserve the required bypass capacitance close to the supply pins and route feedback paths away from high-impedance input nodes. Consider whether the 6 V maximum supply and low-power operating point satisfy the system’s noise, slew-rate, and load requirements.
This page consolidates verified manufacturer and distributor information, observed pricing, same-package alternatives, and practical design guidance for engineers evaluating the TLV2464CN. It also distinguishes documented electrical characteristics from values that require confirmation in the complete manufacturer datasheet.

典型应用
TLV2464CN 适用于 6 应用s: Portable Sensor Signal Conditioning, Battery-Powered Measurement Systems, Low-Voltage Communications Front End, Precision Analog Buffering, Audio Preamplifier and Filter Stages, Industrial Process Monitoring.
Portable Sensor Signal Conditioning
The TLV2464CN fits portable sensing systems because it combines four rail-to-rail-input amplifiers with approximately 500 µA of supply current per channel. The 14-pin PDIP package simplifies through-hole prototyping, while the 6.4 MHz gain-bandwidth provides more bandwidth than slow micropower amplifiers. It can condition temperature, pressure, strain-gauge, or resistive-sensor outputs when those signals remain within the amplifier’s supply and common-mode limits. Rail-to-rail input capability is especially useful when the transducer operates near a rail. The 80 mA output-drive figure can support modest ADC input networks, although the ADC’s sampling capacitor and acquisition requirements must be checked before the source impedance is finalized.
推荐
Battery-Powered Measurement Systems
The TLV2464CN is useful in battery-powered instruments where four analog channels must operate from a nominal 6 V supply. Its approximately 500 µA per-channel supply current limits the amplifier contribution to system power, while the 6.4 MHz gain-bandwidth supports signal paths beyond the bandwidth of very slow comparators or precision amplifiers. Four integrated channels can amplify, buffer, or level-shift multiple measurement nodes without requiring separate packages. Because rail-to-rail output operation reduces wasted headroom, the device may be useful near the upper or lower supply limit. Final battery-life calculations should include the complete application load, regulator efficiency, and the operating mode selected for each channel.
推荐
Low-Voltage Communications Front End
The TLV2464CN can support low-voltage communications equipment that requires multiple low-power signal-conditioning channels. Rail-to-rail inputs help process signals close to the supply rails, and the 6.4 MHz gain-bandwidth product is suitable for moderate-frequency modulation, filtering, and buffering stages. The four-channel arrangement can handle separate receive or monitor paths within one package, while 80 mA output-drive capability offers useful margin for moderate resistive loads. This does not automatically make the device suitable for every RF or high-speed communications path; gain-bandwidth, slew rate, noise, distortion, and stability must be evaluated at the intended signal amplitude and load. Layout should keep feedback routing short and separate from sensitive input traces.
推荐
Precision Analog Buffering
The TLV2464CN can buffer sensor outputs, reference nodes, and intermediate analog signals in equipment built around a 6 V supply. Rail-to-rail output capability helps preserve signal swing in low-headroom designs, while the 6.4 MHz gain-bandwidth allows the amplifier to follow signals whose frequency is well above DC. Four channels permit reuse in gain-stage, filter, and monitoring sections of a measurement instrument. The 500 µA per-channel supply-current figure is attractive for portable equipment, although it should not be interpreted as total board quiescent current. Validate input offset, bias current, noise, capacitive loading, and output stability against the source impedance and desired measurement accuracy before treating the TLV2464CN as a precision instrumentation amplifier.
推荐
Audio Preamplifier and Filter Stages
The TLV2464CN can serve in low-level audio preamplifier, equalizer, and active-filter circuits when a 6 V supply and four amplifier channels are convenient. Its rail-to-rail input and output characteristics support operation over much of the available signal range, and the 6.4 MHz gain-bandwidth provides useful headroom for moderate audio-band circuitry. The approximately 500 µA per-channel supply current is beneficial in portable audio equipment, while the 80 mA output-drive capability can drive higher-impedance headphone or line-stage networks. Audio performance still depends on the complete noise, distortion, offset, and slew-rate data, which should be checked from the manufacturer datasheet. Coupling capacitors, feedback resistors, and output isolation must also be selected for the intended impedance.
推荐
Industrial Process Monitoring
The TLV2464CN is suitable for process-monitoring electronics that compare, amplify, and filter several low-voltage analog nodes. The four-channel package reduces the component count in a panel or controller, and the 14-pin PDIP format is convenient for leaded assembly and serviceable prototypes. Rail-to-rail inputs support sensors whose output can occupy much of the 6 V signal range, while the 6.4 MHz bandwidth handles faster process-control signals than a slow micropower amplifier. The approximately 500 µA per-channel consumption is useful in distributed or battery-backed installations. For industrial use, verify the exact operating-temperature grade, isolation requirements, transient protection, and grounding strategy. Sensor wiring should use suitable shielding or filtering to prevent common-mode interference from corrupting low-level measurements.

设计说明
Budget the TLV2464CN supply current from the verified figure of approximately 500 µA per channel. Four continuously active channels can consume about 2 mA before accounting for input bias current, output load current, and external circuit losses. Because this calculation is arithmetic rather than a datasheet maximum, treat it as an estimate. Confirm the complete recommended operating conditions and quiescent-current limits before sizing a low-power regulator or battery budget.
Place the required bypass capacitor immediately adjacent to the supply pins and provide a low-impedance ground return. Keep each amplifier’s feedback loop compact and route input and output traces away from the same physical region to reduce parasitic coupling between the four channels. For instrumentation boards with high-impedance sensors, use guarded grounding and separate analog signal paths from switching nodes. These layout practices reduce pickup and feedback errors that may otherwise obscure the device’s rail-to-rail performance.
Do not treat rail-to-rail input and output as unlimited. Input and output voltages must remain inside the manufacturer’s absolute-maximum and recommended operating limits, and the exact input protection behavior is not available in the supplied snippets. Similarly, the 6.4 MHz gain-bandwidth figure is not a guaranteed closed-loop bandwidth at every gain or load. Verify offset voltage, slew rate, output swing, stability, and shutdown-pin requirements in the full TLV2464 datasheet before production release.
