TLV2402ID - Dual 16V 5.5kHz RRIO Amplifier | Texas Instruments
料号： TLV2402ID ✓ 量产中TLV2402ID 概述
An operational amplifier is an analog integrated circuit that uses high-gain feedback to amplify the difference between two input voltages. The TLV2402 belongs to the broader operational-amplifier hierarchy, where it combines low quiescent current, rail-to-rail input and output operation, and reverse-battery protection. These characteristics place it between general-purpose precision amplifiers and micropower amplifiers designed for portable or energy-limited equipment.
The verified family description identifies rail-to-rail input and output stages, wide supply-voltage capability, high common-mode rejection, and reverse-battery protection. Rail-to-rail input operation allows the input common-mode voltage to extend toward the supply rails, which is important when sensing signals across most of the available input range. Rail-to-rail output operation permits the output to approach either rail, improving usable output swing in low-voltage systems. Reverse-battery protection helps guard the amplifier against excessive current caused by improper battery installation.
The 5.5 kHz gain-bandwidth product supports low-frequency signal amplification rather than high-speed waveform processing. Because the dual device provides two amplifiers in one package, both channels use the same supply and are intended to share common operating conditions. The approximately 900 nA per channel supply current is particularly important for battery-powered sensors, portable meters, and industrial monitoring devices that remain active for long periods.
Typical applications include low-current sensor conditioning, portable measurement systems, battery-powered monitors, low-frequency filtering, and general-purpose analog signal processing. The 8-pin SOIC package can be assembled using conventional surface-mount production methods, while the dual-channel configuration reduces component count when a design requires two amplified signals or a gain stage plus an active filter.
Designers should verify the complete electrical limits, common-mode range, output-swing behavior, stability requirements, and recommended external components in the manufacturer datasheet before releasing a production design. Because the verified information does not include the complete pin table, numeric common-mode-rejection values, input-offset specifications, or recommended external capacitor values, those details require confirmation from the authoritative TLV2402 documentation.
This product record combines the verified Texas Instruments family description, distributor availability information, package identification, and design guidance. It also distinguishes the only supported same-footprint substitute found in the supplied cross-reference results and clearly identifies missing technical values that should be obtained from the manufacturer datasheet before precise circuit calculations are performed.

典型应用
TLV2402ID 适用于 6 应用s: Battery-Powered Sensor Conditioning, Portable Environmental Monitoring, Low-Power Active Filtering, Industrial Current-Sensing Interface, Battery Voltage and Current Acquisition, Low-Power Audio and Communications Buffering.
Battery-Powered Sensor Conditioning
The TLV2402ID fits low-energy sensor interfaces because the verified family specification identifies approximately 900 nA of supply current per channel while providing rail-to-rail input and output operation. A typical implementation amplifies a low-level sensor signal before an ADC samples the result, using the 5.5 kHz gain-bandwidth product for signals well below the amplifier's bandwidth limit. The rail-to-rail input stage is useful when the sensed voltage approaches a supply rail, while the rail-to-rail output helps maximize signal range in a low-voltage system. Because the complete offset, noise, and common-mode limits were not included in the verified search data, those values should be checked against the manufacturer's datasheet before defining the smallest measurable signal.
推荐
Portable Environmental Monitoring
The TLV2402ID is appropriate for portable environmental-monitoring equipment that must condition several slowly changing analog inputs without consuming substantial battery power. Its dual configuration can support two measurement channels in one 8-pin SOIC, reducing board area compared with two separate single-channel packages. The approximately 900 nA per channel current is especially relevant for devices expected to operate for long periods between battery replacements. Rail-to-rail input and output behavior provides useful signal range when the system operates from a compact supply, although the exact common-mode limits and output-swing data must be obtained from the official datasheet before final gain and offset calculations.
推荐
Low-Power Active Filtering
The TLV2402ID can implement first-order or low-frequency active-filter stages because its verified 5.5 kHz gain-bandwidth product and approximately 900 nA per channel supply current favor low-frequency, low-power signal processing. Two amplifier channels may be combined into an inverting or non-inverting topology, or the package may support two independent filtering paths. Actual filter stability and capacitor selection depend on gain, source impedance, load, and the complete frequency-response curves in the manufacturer documentation. The 16 V maximum supply also allows the device to operate from supplies below that limit, but it does not establish minimum or maximum operating-rail recommendations without consulting the datasheet.
推荐
Industrial Current-Sensing Interface
The TLV2402ID can serve as the low-frequency gain stage of an industrial current-sensing interface when the input network keeps the amplifier's differential voltage within its specified range. Rail-to-rail input operation is useful around a mid-supply-referenced shunt signal, while the 5.5 kHz bandwidth is suitable for many averaged current measurements rather than high-frequency pulse detection. The dual package allows one channel to amplify the shunt signal while the other provides buffering or an active-filter function. Designers should verify input offset voltage, CMRR, input bias behavior, and maximum common-mode voltage from the authoritative datasheet because numerical values for those parameters were not present in the supplied search snippets.
推荐
Battery Voltage and Current Acquisition
The TLV2402ID is useful in battery-powered acquisition systems that measure supply voltage and a scaled current signal through two separate amplifier channels. Its low per-channel supply current helps limit the overhead introduced by analog conditioning, and the rail-to-rail output can provide a larger usable measurement span at low supply voltages. A typical design scales the shunt and battery voltage to an ADC input range, then uses the amplifier outputs to improve signal compatibility with the converter. The verified material does not provide the input-offset or noise values needed to calculate absolute measurement uncertainty, so those specifications should be checked in the manufacturer datasheet and in the complete system error budget.
推荐
Low-Power Audio and Communications Buffering
The TLV2402ID can provide low-frequency buffering for audio-control, microphone-bias monitoring, or communications signal paths where the required bandwidth is modest and supply current matters. Its dual-channel 8-pin SOIC package supports independent signal stages, while the approximately 900 nA per channel current favors portable equipment. The verified 5.5 kHz gain-bandwidth product indicates suitability for control and voice-band functions rather than wideband audio or RF signal paths. Designers should avoid assuming that the generic high-CMRR description guarantees a particular audio performance figure, and should review the manufacturer's input-noise, output-swing, and load-capability curves before using the amplifier with demanding speakers, microphones, or line-level networks.

关键差异点
- Lower current consumption than common general-purpose dual amplifiers （对比 LM324D)
- Rail-to-rail signal range from a 5.5 kHz micropower dual amplifier （对比 TLV1504ID)
- Same-footprint commercial-grade replacement for room-temperature systems （对比 TLV2402CDR)
设计说明
Budget the approximately 900 nA per channel supply current together with the load current drawn by the external sensor, resistor network, and output circuit. Estimated: two channels at 900 nA each consume approximately 1.8 µA of amplifier supply current. This estimate excludes input bias current, output load current, leakage, and the current required by any ADC or external reference. Confirm these additional contributions against the complete circuit because they can dominate the amplifier's own consumption in a battery-powered design.
Do not treat the 16 V maximum supply rating as proof that the amplifier can operate across every supply voltage up to that limit. Before power-up, check the manufacturer's minimum and maximum recommended supply specifications, input common-mode limits, output-swing limits, and absolute maximum ratings. Also verify that reverse-battery protection is relevant to the final installation method; the protected condition does not authorize repeated reversal or protection against all reverse-energy events.
Place the amplifier, feedback resistors, and any frequency-compensation or filtering components close together to minimize parasitic capacitance and feedback-loop instability. Keep sensitive input traces away from switching nodes and high-current paths. Because the verified 5.5 kHz bandwidth is sufficient for many low-frequency sensing tasks, careful grounding and short feedback routes are generally more valuable than high-frequency layout complexity, but the final layout should still follow the manufacturer layout guidance for the selected gain and load.
合规信息
The supplied verified search results do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. The generic dual operational-amplifier function makes AEC-Q100 qualification not directly applicable unless a specific automotive-qualified orderable device is selected.
