MP8103DK-LF-P Dual 200 kHz Low-Power Op Amp | MPS
Référence : MP8103DK-LF-P ✓ ActifMP8103DK-LF-P Présentation
An operational amplifier, or op amp, is a high-gain differential amplifier used to compare and amplify small voltage signals. The MP8103 is a dual amplifier, so one package contains two independent amplifier channels. It belongs to the general-purpose amplifier class within integrated circuits and is intended for functions such as voltage buffering, sensor conditioning, current-voltage conversion, and gain-stage implementation when low supply current is more important than high bandwidth.
The verified distributor information identifies the MP8103 as a 200 kHz gain-bandwidth device, while another indexed datasheet description identifies 600 kHz bandwidth for the MP8103 family. It is a rail-to-rail-output amplifier with a maximum indicated supply voltage of 5.5 V and an exceptionally low 14 µA supply current. Operation from 1.8 V permits use in systems where the available energy budget limits continuous amplifier consumption.
The MP8103’s dual-channel configuration saves board area compared with two separate single amplifiers, while its MSOP package supports compact layouts. Rail-to-rail output behavior can simplify designs that require the output to approach the available supply range. Engineers should nevertheless verify output swing, input common-mode range, offset voltage, noise, stability, and load-driving capability against the manufacturer datasheet before committing a high-impedance or precision application.
Typical uses include low-power sensor interfaces, portable instrumentation, battery-powered condition-monitoring circuits, and low-frequency analog signal chains. The 14 µA supply current is particularly useful when the amplifier must remain continuously powered, while 200 kHz bandwidth provides adequate response for many sensor and control signals rather than high-speed waveform applications.
The primary design consideration is supply headroom. Because the device can operate from 1.8 V, the selected output must remain within the verified output-swing limits at the intended load. Input bias currents should also be compared with source impedances to prevent avoidable DC errors, and each power rail should be decoupled close to the device pins.
This page consolidates verified distributor specifications, sourcing information, package details, application guidance, and engineering caveats. It distinguishes confirmed MP8103DK-LF-P attributes from parameters that remain unavailable in the supplied web data, supporting more accurate design-in and procurement decisions.

Applications typiques
MP8103DK-LF-P convient pour 6 applications: Battery-Powered Sensor Conditioning, Portable Instrumentation, Low-Frequency Signal Buffering, Current-to-Voltage Conversion, Low-Power Control Loops, Compact Analog Signal Conditioning.
Battery-Powered Sensor Conditioning
The MP8103DK-LF-P fits low-energy sensor interfaces because it operates from a single supply as low as 1.8 V and consumes approximately 14 µA of supply current. A typical circuit can use one channel to amplify a transducer signal and the second to buffer a reference or drive a monitor input. According to the manufacturer-family description, the dual topology reduces component count, while its rail-to-rail output can provide useful headroom in compact systems. Designers should verify input bias current against sensor impedance and check common-mode and output-swing limits in the manufacturer datasheet.
Recommandé
Portable Instrumentation
The MP8103DK-LF-P is appropriate for portable measurement circuits where continuous amplifier power can constrain battery life. Its approximately 14 µA supply current and 1.8 V minimum single-supply operation support low-energy acquisition systems, while the listed 200 kHz gain-bandwidth product is adequate for many low-frequency measurements. The dual-amplifier arrangement can implement gain and buffer stages in one 8-MSOP package. For precision work, engineers should confirm offset voltage, bias current, noise, and output accuracy because those parameters were not available in the supplied verified snippets.
Recommandé
Low-Frequency Signal Buffering
The MP8103DK-LF-P can serve as a voltage follower when a higher-impedance source must drive a downstream measurement block. A follower preserves signal amplitude while providing low output impedance, and the device’s listed 200 kHz gain-bandwidth product gives useful closed-loop performance for low-frequency signals. The rail-to-rail output helps preserve signal range at low supply voltage. According to the verified distributor description, this is a general-purpose dual amplifier in an 8-MSOP, making it practical for two buffered channels on a compact mixed-signal board.
Recommandé
Current-to-Voltage Conversion
A transimpedance application can use one MP8103 channel to convert a small current into a measurable voltage, while the second channel can buffer or amplify a related signal. The amplifier’s 1.8 V minimum supply supports low-voltage systems, and its approximately 14 µA supply consumption helps preserve energy budget. Compared with a discrete implementation, the dual MSOP package reduces board area. Designers must account for input bias current, input common-mode range, feedback-resistor stability, and the bandwidth selected with the transimpedance network; those details require confirmation from the manufacturer datasheet.
Recommandé
Low-Power Control Loops
The MP8103DK-LF-P can implement error amplification or control-signal conditioning in compact industrial and embedded systems. Its listed 200 kHz gain-bandwidth product supports loop dynamics well beyond basic slow feedback functions, while approximately 14 µA supply current is useful in distributed low-power nodes. The dual channel allows a control amplifier and a monitoring or output-buffer amplifier to share one package. The application remains dependent on output swing, stability with capacitive loading, and supply-noise behavior, which should be checked using the manufacturer’s test and stability information.
Recommandé
Compact Analog Signal Conditioning
The MP8103DK-LF-P is suitable for compact analog conditioning blocks that need two general-purpose channels without allocating space for separate single amplifiers. Its 8-MSOP surface-mount package supports dense layouts, and operation from 1.8 V allows direct integration with low-voltage sensors and digital converters. According to Mouser, the device is a dual 200 kHz GBW, 5.5 V low-power op amp. Engineers should use the manufacturer pin drawing for layout and verify channel independence, input range, output swing, and decoupling requirements before production.

Principaux différenciateurs
- Very low supply consumption for a dual amplifier (vs MP8103DK-LF-Z)
- Low-voltage operation suitable for portable systems (vs MP8103DK-LF)
- Two channels in one compact package (vs MP8103DK-LF-Z)
Notes de conception
The verified 1.8 V minimum operating voltage enables low-voltage operation, but the circuit must maintain enough supply headroom for the required output swing. The supplied data confirms rail-to-rail output without confirming a rail-to-rail input range. Before selecting gain or output levels, check the manufacturer input common-mode and output-swing graphs at the intended supply voltage and load.
Place the supply-decoupling capacitor close to pins 4 and 8 and route the amplifier inputs away from switching nodes and high-current return paths. The 3.00 mm-wide 8-MSOP package allows compact placement, but its lead pitch still requires careful fanout and ground-return planning. Follow the manufacturer’s recommended layout and capacitance values rather than relying on generic bulk-capacitor guidance.
Do not assume that the dual channels are interchangeable for every application: verify each channel’s intended input and output connections against the manufacturer drawing. Also avoid mixing the 200 kHz figure reported by Mouser with the 600 kHz family figure reported in another indexed source. For high-impedance sources, input bias current and electrostatic protection should be reviewed before release.
