MP8130DJ-LF-Z - 36V 200kHz Low-Power Op Amp | MPS
MPN： MP8130DJ-LF-Z ✓ 啟用中MP8130DJ-LF-Z 概覽
An operational amplifier, or op amp, is a high-gain analog amplifier intended for feedback-based applications. The MP8130 is a general-purpose precision analog device whose rail-to-rail output allows the output voltage to approach the supply rails under suitable load and output conditions. Its single-supply operating range of 2.7 V to 36 V places it within the voltage-regulator and power-management IC ecosystem as a signal-conditioning component rather than a power-conversion device.
Key characteristics include a 200 kHz gain-bandwidth product, approximately 10 uA supply current, 82 dB CMRR, and a 0.1 V/us slew rate. The combination of high-voltage tolerance and low quiescent current makes the device useful where a conventional low-voltage amplifier would not tolerate the available supply voltage. The TSOT-23-5 package supports space-constrained PCB layouts while retaining five-pin operational-amplifier connectivity.
The MP8130 is optimized for low-frequency closed-loop operation rather than high-speed signal processing. Its bandwidth limits how quickly the output can respond to small-signal inputs, while the 0.1 V/us slew rate limits large-signal transitions. Feedback-network values, load capacitance, input common-mode range, and supply bypassing should therefore be checked against the manufacturer datasheet before deployment in precision or high-speed designs.
Typical applications include low-power sensor conditioning, industrial control and monitoring, portable instrumentation, battery-operated measurement systems, and analog signal buffering. The 36 V maximum supply rating can simplify designs that operate from industrial rails, although the actual operating range must remain within the specified 2.7 V to 36 V limits and the total supply voltage must not exceed the device rating.
For PCB implementation, place input and output bypass capacitors close to the amplifier pins and use low-ESL, low-ESR surface-mount ceramic capacitors. Keep feedback traces short and separate high-current return paths from sensitive input nodes. The manufacturer datasheet should be consulted for the complete electrical-characteristics table, input and output limits, and package drawings.

典型應用
MP8130DJ-LF-Z 適用於 6 應用s: Industrial Sensor Signal Conditioning, Battery-Powered Monitoring Circuit, Portable Instrumentation Front End, Data Acquisition Analog Input, Automotive Low-Speed Sensor Interface, Low-Power Voltage Signal Buffer.
Industrial Sensor Signal Conditioning
The MP8130DJ-LF-Z is well suited to conditioning slow sensor signals in industrial systems because it accepts a 2.7 V to 36 V single supply and consumes a typical 10 uA. Place the amplifier in a non-inverting or differential-feedback configuration according to the sensor impedance, then use low-ESL decoupling close to the supply pins. Its 200 kHz bandwidth is ample for many temperature, pressure, and position sensors, while the 82 dB CMRR helps reject common-mode disturbances. The 0.1 V/us slew rate should be considered when large output steps are possible, and the selected feedback resistors must preserve the required input-referred offset and bias-current performance.
推薦
Battery-Powered Monitoring Circuit
For battery-powered remote monitoring, the MP8130DJ-LF-Z combines a 2.7 V minimum supply with a typical 10 uA supply current, reducing the contribution of the amplifier to total system power. It can buffer sensor outputs or amplify low-frequency currents across a broad operating-voltage range. Because the device is designed for low power rather than the very lowest input offset or noise, engineers should verify offset voltage, input bias current, and noise against the measurement resolution. A local bypass capacitor and high-impedance bias resistors help control supply noise and unintended loading during long battery-life operation.
推薦
Portable Instrumentation Front End
The MP8130DJ-LF-Z can serve as the analog input stage of portable test and measurement equipment when the design must tolerate supply transients or operate near higher industrial voltages. Its 200 kHz gain-bandwidth product supports low-frequency instrumentation, and rail-to-rail output improves usable signal range on a single supply. The 36 V capability does not imply high-speed performance, so the amplifier is most appropriate for pressure, level, temperature, and slowly varying voltage measurements. Use short input traces, guard against leakage on high-impedance nodes, and verify that output swing remains within limits under the intended load and temperature.
推薦
Data Acquisition Analog Input
For multiplexed or distributed data-acquisition systems, the MP8130DJ-LF-Z can buffer sensor lines or provide gain before an ADC. Its single-circuit implementation reduces board area in a TSOT-23-5 package, while 82 dB CMRR is useful when the source includes substantial common-mode noise. The 200 kHz bandwidth and 0.1 V/us slew rate are suitable for many low-rate acquisition channels but may be insufficient for wideband multiplexed systems requiring settling after channel changes. Choose feedback resistors and capacitors that control bandwidth, settle time, and output drive without relying on the op amp to compensate for excessive source impedance.
推薦
Automotive Low-Speed Sensor Interface
The MP8130DJ-LF-Z may be considered for low-speed, non-safety-critical sensor interfaces where a 36 V supply tolerance and low 10 uA consumption are valuable. Its general-purpose topology can buffer, amplify, or level-shift signals within the device's electrical limits. However, the verified data does not state AEC-Q100 qualification, so automotive production use requires confirmation from the manufacturer rather than assumption. Keep transient protection and filtering outside the sensitive input path, provide local supply bypassing, and verify that load dumps or automotive transients do not exceed the specified supply and pin limits.
推薦
Low-Power Voltage Signal Buffer
The MP8130DJ-LF-Z can buffer medium-impedance voltage sources in low-power acquisition, control, and embedded analog systems. Its 10 uA typical supply current supports efficient operation, while the 2.7 V to 36 V supply range allows deployment across multiple rail voltages. Rail-to-rail output can improve signal utilization, although the exact output swing depends on load current. Keep source impedance and feedback resistance in a range where input bias-current and offset errors remain acceptable, and use a small output isolation capacitor when driving a downstream sampling capacitor or when stability requires frequency compensation.

主要差異化特點

設計說明
Decouple the MP8130 supply with a low-ESL, low-ESR ceramic capacitor placed as close as practical to the device, and add a second local capacitor if the supply trace is long or the source impedance is high. The manufacturer datasheet notes that low-ESL and low-ESR capacitors are preferred. Keep the bypass return path short because its inductance can create supply-to-output coupling and reduce the benefit of the amplifier's low-noise operation.
Route the non-inverting input, feedback components, and output as short and compact as practical, and keep them away from switching-node and high-current return paths. For high-impedance sources, minimize leakage and contamination on the input node because PCB contamination can create an error larger than the amplifier's intended input offset. Maintain symmetry between the differential input branches where practical to reduce offset from mismatch.
Do not treat the 36 V supply capability as permission to exceed the maximum total supply voltage or individual pin voltage. The provided data confirms rail-to-rail output but does not establish the complete input common-mode range. Verify input and output absolute maximum ratings, operating-region limits, and output-current behavior in the official datasheet before connecting the device to high-voltage sources or capacitive loads.
