TLV2362ID - Dual 7MHz Low-Noise Amplifier | Texas Instruments
部品番号: TLV2362ID ✓ 生産中TLV2362ID 概要
An operational amplifier is a voltage-feedback analog signal-conditioning component that compares its differential input voltage with a feedback-defined reference and drives its output to reduce the difference between them. The TLV2362 belongs to the dual operational-amplifier family, combining two amplifiers in one package for signal amplification, buffering, filtering, active gain control, and analog-to-digital converter input conditioning. The 8-pin SOIC form factor supports conventional surface-mount PCB assembly.
The TLV2362ID provides 8 nV/√Hz input-voltage noise density and a 7 MHz gain-bandwidth product. Low input noise helps preserve small signals during amplification, while the 7 MHz bandwidth supports signals extending well above audio frequencies. Operation from ±1 V supports low-energy systems where supply headroom is limited, and the dual configuration can process two channels while reducing board area.
According to the Texas Instruments product description, the TLV2362 family uses an original bipolar process and maintains a wide output-swing capability even at very low supply voltages. This architecture is relevant when designing low-voltage sensor paths because the amplifier can operate near the lower limit of the stated supply range without requiring a negative rail in single-supply systems, provided the input and output signals remain inside the device's operating limits.
Typical applications include low-level sensor conditioning, audio and microphone preamplification, portable measurement equipment, active filtering, and buffering signals for higher-resolution analog-to-digital converters. In a dual-signal system, one channel may amplify a sensor output while the other monitors a reference, provides gain, or drives a control signal. The same-package pairing also reduces component count compared with two separate single amplifiers.
Design layouts should keep input, feedback, and decoupling connections short, use a solid ground reference, and place the power-bypass capacitor close to the supply pins. Confirm the input common-mode range, output swing, supply limits, and stability requirements against the manufacturer datasheet before operating near the voltage boundaries. For applications requiring different noise, bandwidth, rail-to-rail input-output behavior, or shutdown control, compare the alternative amplifier families rather than assuming that every low-voltage dual op amp is interchangeable.

Low-Level Sensor Signal Conditioning
The TLV2362ID suits low-level sensor paths because its 8 nV/√Hz input-voltage noise density helps limit the amplifier's contribution to small-signal errors. One channel can amplify a sensor output while the second channel buffers a reference or monitors another input. Its 7 MHz gain-bandwidth product provides substantially more bandwidth than a basic precision op amp, while ±1 V operation supports compact, low-voltage instrumentation. Confirm that the sensor's common-mode voltage and required output swing remain inside the manufacturer's limits.
おすすめ
Portable Measurement and Instrumentation
Battery-powered measurement equipment can benefit from the TLV2362ID's ability to operate from ±1 V and its two amplifiers in one 8-pin SOIC package. The amplifiers can condition two measurement channels or provide gain and buffering for a sensor interface. An input-noise density of 8 nV/√Hz and a 7 MHz gain-bandwidth product support sensitive, higher-bandwidth signal chains. Power-budget calculations must include the actual quiescent current from the manufacturer datasheet because that value is not established on the product summary.
おすすめ
Audio and Microphone Preamplification
The TLV2362ID can serve as a low-noise preamplifier in audio, microphone, and line-level signal paths. Its 8 nV/√Hz input-voltage noise density is useful when preserving low-amplitude source signals, while the 7 MHz gain-bandwidth product accommodates signal content well above the audible band. The dual configuration can handle stereo channels or combine a signal path with a buffer. Select external gain and coupling values carefully, and verify input bias current, output swing, and channel-to-channel behavior in the manufacturer datasheet.
おすすめ
Active Filtering and Frequency Shaping
The TLV2362ID's 7 MHz gain-bandwidth product makes it suitable for active filters whose useful closed-loop bandwidth extends beyond the audio band. Two amplifiers can implement a second-order active filter or provide signal conditioning before another conversion stage. The device's 8 nV/√Hz input noise supports low-amplitude filter signals. The actual filter response depends on resistor and capacitor tolerances, operating gain, and loop stability, so prototype the selected topology and compare it against the datasheet's recommended compensation conditions.
おすすめ
Industrial Control Signal Buffering
In industrial control systems, the TLV2362ID can buffer sensor and control signals when low noise and modest bandwidth are required. Its dual-channel arrangement can process two related control paths, while the 8-pin SOIC package simplifies assembly and saves board area compared with separate single amplifiers. The 7 MHz bandwidth is adequate for many slow control and instrumentation signals, but it is not intended for high-speed servo loops. Validate noise immunity, input common-mode range, and output drive against the actual control-node voltage.
おすすめ
ADC Input Signal Conditioning
The TLV2362ID can drive or buffer inputs to higher-resolution analog-to-digital converters when the source signal is small and requires amplification. Its 8 nV/√Hz input noise reduces added noise during conditioning, while the 7 MHz gain-bandwidth product permits useful bandwidth above baseband audio rates. One channel may condition the measurement input and the other can buffer a reference or monitor a second input. Check the ADC's input range, acquisition timing, settling requirements, and the amplifier's output capability before finalizing the interface.

設計ノート
Route the two input pins of each amplifier directly to their source or feedback components, and keep feedback resistors close to the relevant input and output pins. This reduces parasitic capacitance and feedback-loop area, which is especially important when using the 7 MHz gain-bandwidth product. Maintain a continuous ground plane beneath and around the SOIC, and avoid routing high-speed or switching-current paths between the input pins and their source nodes.
Place the supply-bypass capacitor immediately across the V+ and V− pins, with a short and low-inductance return to the device ground reference. For dual-supply operation, decouple each rail near the package rather than relying on a remote bulk capacitor alone. The available product summary does not establish a definitive capacitor value, so select it from the manufacturer datasheet's recommended application circuit and validate supply ripple and transient response on the assembled board.
Do not assume that identical package pins guarantee electrical interchangeability between low-voltage op amps. Before using the TLV2402ID as a replacement, compare the input common-mode range, output swing, gain-bandwidth product, noise density, slew rate, input bias current, quiescent current, stability, and supply limits. Also verify whether a single-supply design keeps both input and output voltages within the required range rather than merely meeting the nominal 5 V supply condition.
