MP8102DJ-LF-Z - 600kHz Low-Power RRIO Op Amp | MPS
Teilenummer: MP8102DJ-LF-Z ✓ AktivMP8102DJ-LF-Z Übersicht
An operational amplifier is an analog integrated circuit that amplifies the difference between its inverting and non-inverting inputs. A rail-to-rail-output amplifier can approach the supply rails at its output, which helps maximize usable output voltage in low-voltage systems. Within the broader hierarchy, the MP8102 is an operational amplifier, analog amplifier IC, signal-conditioning IC, and power-management-support semiconductor designed around low-voltage, low-power signal processing.
The MP8102 combines a 600kHz gain-bandwidth product with supply current of 7.5µA. It supports a 5V supply according to the retrieved specification data and can operate from a single supply as low as 1.8V. Additional reported characteristics include 82dB common-mode rejection, 0.1V/µs slew rate, and a maximum input offset voltage of 5mV. Its rail-to-rail output architecture improves output headroom when the amplifier operates close to the available supply voltage.
The 600kHz bandwidth makes the MP8102 suitable for modest-frequency signal amplification rather than high-speed video or RF tasks. Its 7.5µA supply current reduces power consumption in continuously powered instrumentation, while the small TSOT-23 package supports space-constrained boards. The 0.1V/µs slew rate defines how quickly the output can move under suitable loading and should be checked against large-signal and capacitive-load requirements.
Typical uses include low-voltage sensor conditioning, battery-powered measurement nodes, audio and communication interface buffers, microcontroller analog front ends, and general-purpose signal amplification. Its rail-to-rail output behavior is particularly useful when the processed signal must occupy much of the available 1.8V-to-5V supply range. The TSOT-23 package also requires careful PCB layout and adequate thermal spreading for reliable operation.
When designing around the MP8102, verify the exact input common-mode range, output swing, output-current capability, noise, and stability with capacitive loads against the manufacturer datasheet. Place the device close to the feedback network and bypass its supply pins with a short, low-inductance connection to minimize instability, ground offset, and susceptibility to switching-node noise.
This product record consolidates the verified manufacturer and distributor data with practical design guidance, application analysis, lifecycle-relevant sourcing information, and an explicit separation between documented characteristics and parameters that still require datasheet confirmation.

Typische Anwendungen
MP8102DJ-LF-Z ist geeignet für 6 Anwendungs: Battery-Powered Sensor Signal Conditioning, Low-Voltage Audio Interface Buffer, Microcontroller Analog Front End, Portable Medical Monitoring Module, Industrial Process Measurement Node, Communications Interface Buffer.
Battery-Powered Sensor Signal Conditioning
The MP8102DJ-LF-Z fits low-energy sensor front ends because it operates from a single supply as low as 1.8V while consuming 7.5µA. According to the manufacturer datasheet, its rail-to-rail-output architecture helps preserve usable signal range in a compact 5-pin TSOT-23 package. It can amplify a sensor signal before conversion by an ADC or provide buffering between a sensor and a microcontroller input. The engineer should verify the exact input common-mode range and output swing against the sensor’s operating range. Offset voltage, noise, and the power consumed by the rest of the acquisition chain must also be included in the error and energy budget.
Low-Voltage Audio Interface Buffer
The MP8102DJ-LF-Z is appropriate for low-level audio buffering in portable and compact systems where supply voltage and power consumption are constrained. Its rail-to-rail output can support signals approaching the available supply range, while the 600kHz gain-bandwidth product provides bandwidth above typical audio fundamentals. According to the manufacturer datasheet, the amplifier consumes 7.5µA and can run from 1.8V, making it a candidate for headphone, microphone, and line-level conditioning stages. Confirm the output-current capability, input voltage range, noise density, and stability into the next stage before committing to the design.
Microcontroller Analog Front End
The MP8102DJ-LF-Z can serve as the analog gain or buffer stage between a transducer and a microcontroller ADC. Its 600kHz gain-bandwidth product is sufficient for many low-frequency control, monitoring, and instrumentation signals, and the 5-pin TSOT-23 package saves board area. According to the manufacturer datasheet, single-supply operation begins at 1.8V and supply current is 7.5µA. The important design checks are ADC input range, sample-and-hold kickback, common-mode limits, settling time, and the amplifier’s 5mV maximum input offset specification where measurement precision matters.
Portable Medical Monitoring Module
The MP8102DJ-LF-Z can support signal amplification in a compact monitoring module when the system operates from a low single supply. Its 1.8V minimum supply, 7.5µA supply current, rail-to-rail output, and -40°C to +85°C operating range provide a useful starting point for low-power acquisition electronics. According to the manufacturer datasheet, the device has a 600kHz gain-bandwidth product and a small TSOT-23 footprint. Medical use nevertheless requires application-specific validation, including patient protection, isolation, diagnostic accuracy, input protection, noise analysis, and confirmation of any medical-device quality requirements; no such qualification is claimed here.
Industrial Process Measurement Node
The MP8102DJ-LF-Z is suitable for low-frequency industrial measurement nodes where a conditioned sensor output must be amplified before digitization or transmission. Its 600kHz bandwidth handles many process, pressure, and position-sensor signals, while rail-to-rail output improves utilization of the available supply. According to the manufacturer datasheet, the amplifier operates from 1.8V and has a 7.5µA supply current, but its -40°C to +85°C range and non-automotive documentation should be checked against the installation environment. Protective filtering, surge handling, grounding, and long-cable input stability must be evaluated separately at the system level.
Communications Interface Buffer
The MP8102DJ-LF-Z can provide local gain or impedance buffering around low-speed communications and control interfaces in compact equipment. According to the manufacturer datasheet, the 600kHz gain-bandwidth product is adequate for many low-frequency interface paths, and the 7.5µA supply current supports power-constrained nodes. The TSOT-23 package allows placement near the source of the signal to reduce trace sensitivity. Designers must still confirm input and output voltage limits, drive capability, channel settling, logic-level offsets, and stability. The amplifier’s 0.1V/µs slew rate also needs to be compared with the required signal edge rate.

Designhinweise
Route the MP8102DJ-LF-Z supply pins directly to a local bypass capacitor and keep the power loop compact. Place feedback resistors close to the amplifier pins, and avoid routing the high-impedance input beside switching nodes, inductors, or long clock and data traces. For the 5-pin TSOT-23 implementation, confirm the manufacturer’s recommended land pattern and pin-1 orientation before fabrication. Good local grounding and short analog paths are especially important because the amplifier’s low 7.5µA supply current makes the circuit capable of operating correctly only when board-level leakage and grounding are well controlled.
Do not assume that rail-to-rail output automatically means the input common-mode range reaches both rails. The supplied data does not include the complete input range, so verify it in the manufacturer datasheet against the actual sensor or source output. Likewise, the 600kHz gain-bandwidth product does not by itself establish stability with capacitive loads. Check the recommended feedback network and maximum capacitive load, add an isolation resistor if required by the datasheet, and test long cables and ADC inputs on the final layout.
Budget the complete analog-channel power consumption rather than using the 7.5µA amplifier current alone. The amplifier’s 1.8V minimum single-supply operation is useful for energy reduction, but the source, bias network, ADC, protection elements, and level-shifting circuitry can dominate current. Confirm the maximum input and output voltage at temperature and process corners, and verify that the 0.1V/µs slew rate supports the largest expected signal excursion. A low-power amplifier does not guarantee low total system power if downstream conversions require a faster or more accurate reference.
For low-level measurements, treat offset, bias current, noise, and common-mode error as a combined signal-chain specification. The retrieved data lists a maximum input offset voltage of 5mV and CMRR of 82dB, which may require gain, calibration, or a front-end choice with lower offset. Keep high-impedance sensor traces short, provide adequate input-bias return paths, and isolate the amplifier from digital switching activity. Verify settling behavior at the intended closed-loop gain rather than assuming bandwidth alone meets the conversion timing requirement.
Compliance-Informationen
The retrieved product data identifies the device as RoHS compliant, and the -LF-Z ordering suffix indicates a lead-free variant. REACH, halogen-free, and conflict-minerals declarations were not included in the supplied verified data.
