MP8102DJ-LF-P - 600kHz 1.8V Low-Power Op Amp | MPS
部品番号: MP8102DJ-LF-P ✓ 生産中MP8102DJ-LF-P 概要
An operational amplifier, or op amp, is a high-gain differential amplifier used to amplify, buffer, filter, or compare small voltage signals. The MP8102 family emphasizes low supply current and low-voltage operation rather than the high bandwidth and drive current associated with general-purpose amplifiers. Its rail-to-rail output allows the output voltage to approach the supply limits under suitable load and output conditions, making it useful in compact, low-power sensor and portable systems.
The verified manufacturer description identifies 600 kHz bandwidth, 7.5 µA supply current, and single-supply operation down to 1.8 V. Additional distributor data identifies a 5-pin TSOT-23 package, 82 dB CMRR, and a -40 °C to +85 °C operating-temperature range. The combination of low quiescent consumption and a 600 kHz gain-bandwidth product supports signal paths that require measurable bandwidth without a high-current amplifier architecture.
The MP8102 is a single-amplifier device intended for low-voltage analog signal conditioning. A 1.8 V minimum supply supports energy-limited systems, while the 600 kHz bandwidth is suitable for modest-frequency filtering, buffering, and gain stages. Because the verified excerpts do not provide complete electrical-limit tables, exact input-offset voltage, input-bias current, open-loop gain, noise density, and output-drive specifications should be confirmed in the manufacturer datasheet before production release.
Typical uses include low-power sensor interfaces, portable instrumentation, battery-powered monitoring, current-loop signal conditioning, and small embedded analog front ends. The 7.5 µA supply current is especially relevant when aggregate amplifier consumption dominates a compact design's available power budget. The 600 kHz bandwidth allows the amplifier to process signals beyond DC without behaving as a purely static precision amplifier.
Designers should verify input common-mode range, output swing, capacitive-load stability, noise, and gain-bandwidth behavior directly from the MP8102 datasheet. Decoupling-capacitor values, stability with sensors, and achievable output accuracy are not specified in the supplied excerpts and should not be inferred. PCB layout should keep the input path short and provide a local return path for the supply and ground pins.
This product page consolidates the verified manufacturer description, distributor classification, package information, sourcing links, and engineering limitations for MP8102DJ-LF-P. It also distinguishes verified facts from parameters that still require datasheet confirmation, helping engineers evaluate the part without mistaking distributor classifications for complete electrical specifications.

主な用途
MP8102DJ-LF-P の用途: 6 件s: Battery-Powered Sensor Signal Conditioning, Portable Medical Monitoring, Industrial Current-Loop Conditioning, IoT Edge Sensor Interfaces, Low-Power Active Filtering, Audio and Communication Buffering.
Battery-Powered Sensor Signal Conditioning
The MP8102DJ-LF-P fits low-power sensor front ends where every microamp affects battery life. Its verified 7.5 µA supply current and 1.8 V minimum single-supply operation allow it to process signals close to the sensor's supply rail, while the 600 kHz gain-bandwidth product provides useful bandwidth above DC. The amplifier can serve as a voltage gain stage or impedance buffer before an ADC. Designers must confirm the input common-mode range, output swing, offset voltage, and noise density from the manufacturer datasheet, because those limits determine whether the sensor output remains usable at the 1.8 V minimum supply.
おすすめ
Portable Medical Monitoring
The MP8102DJ-LF-P can support low-level signal conditioning in compact monitoring equipment where rail-to-rail output operation and low supply current are useful. The 1.8 V minimum supply and 7.5 µA amplifier current suit a small battery power budget, while the 600 kHz bandwidth covers slowly varying physiological signals rather than demanding wideband acquisition. A typical chain would amplify a sensor output before an ADC. Medical use also requires quality-system review and verification of input bias current, offset, noise, leakage, and applicable medical-device standards; none of those additional claims are established by the supplied excerpts.
おすすめ
Industrial Current-Loop Conditioning
The MP8102DJ-LF-P is suitable for low-bandwidth current-loop signal conditioning in compact industrial monitoring equipment. Its 600 kHz gain-bandwidth product is well above the signal bandwidth of many 4–20 mA process measurements, and its low 7.5 µA supply current reduces the amplifier's contribution to overall loop-powered instrumentation consumption. Rail-to-rail output operation can improve use of the available supply range. Before selecting it for a harsh industrial environment, verify common-mode range, input protection requirements, output drive into sensor wiring, electromagnetic immunity, and the manufacturer's operating-temperature rating of -40 °C to +85 °C.
おすすめ
IoT Edge Sensor Interfaces
The MP8102DJ-LF-P fits IoT edge-node analog interfaces that must amplify a sensor output without consuming a substantial portion of the system power budget. At 7.5 µA supply current and a 1.8 V minimum supply, it can operate in compact, energy-constrained nodes, while the 600 kHz bandwidth supports sensor signals beyond DC. It may buffer a resistive bridge or transducer output toward an ADC or communications subsystem. The design must check input bias current against high source impedances, offset against required accuracy, and common-mode range against the sensor output; these parameters are not specified in the verified excerpts.
おすすめ
Low-Power Active Filtering
The MP8102DJ-LF-P can implement modest active-filter stages when the signal bandwidth is far below its 600 kHz gain-bandwidth product. Rail-to-rail output operation is useful near low supply voltages, and the 7.5 µA supply current keeps the amplifier from dominating a compact filter's power use. A first-order or low-order Sallen-Key or multiple-feedback topology may be appropriate, but component values must be selected only after checking the datasheet's gain-bandwidth, open-loop-gain, noise, and capacitive-load stability data. The verified excerpts do not establish those complete limits or guarantee a particular compensation network.
おすすめ
Audio and Communication Buffering
The MP8102DJ-LF-P can serve as a low-power buffer or modest-gain stage in portable audio or communication equipment. Its 600 kHz bandwidth covers voice-band and many low-frequency communication signals, while the 7.5 µA supply current supports constrained power budgets. Rail-to-rail output operation can improve headroom at low supply voltages. The amplifier is not characterized in the supplied data for headphone or line-level drive, so output-current capability, distortion, noise density, and stability with cables or capacitive loads must be verified in the manufacturer datasheet before using it in a demanding audio path.

設計ノート
Budget the MP8102DJ-LF-P around its verified 7.5 µA supply current and confirm the exact datasheet test condition before using that figure for worst-case power calculations. At a 1.8 V supply, the stated current corresponds to an estimated amplifier supply power of 13.5 µW using P = VIN × ISUPPLY. This is an estimate based on the verified nominal values, not a datasheet power specification. Add downstream bias, ADC, reference, and communications loads to obtain the complete battery-life budget.
Place the op-amp input, feedback components, and output-connected circuits close to the five TSOT-23 pins to minimize parasitic feedback and sensitivity to induced noise. Keep the ground return short and use a continuous ground reference beneath the circuit rather than routing sensitive return current through narrow neckdowns. Follow the pin numbers in the official MP8102 datasheet; the supplied excerpts establish the five-pin package but do not disclose individual pin assignments.
Do not select the MP8102 solely from its 600 kHz bandwidth and 7.5 µA current rating. Verify input common-mode range, output voltage swing, input-bias current, offset voltage, noise density, and capacitive-load stability from the manufacturer datasheet. A sensor with a high source impedance can expose input-bias error, while driving a long cable or large capacitor can expose output-drive or stability limitations. These parameters were not present in the supplied search excerpts and must not be inferred from generic TSOT-23 op-amp behavior.
Use the 600 kHz gain-bandwidth figure as a design limit, not as permission to create a high-Q filter or unstable closed-loop stage near the amplifier's bandwidth. Higher closed-loop gain reduces available bandwidth and phase margin, and capacitive loading can further alter stability. Confirm the permitted capacitive load and recommended feedback network in the manufacturer datasheet. For low-frequency sensor conditioning, choose resistor and capacitor values that keep the closed-loop response well below the verified bandwidth limit.
コンプライアンス情報
The supplied search data does not contain an authoritative compliance declaration for the exact MP8102DJ-LF-P order code. A third-party summary calls the related MP8102DJ-LF configuration RoHS compliant, but the exact-part status remains unknown until confirmed by Monolithic Power Systems.
