Monolithic Power Systems Inc. MP8130DJ-LF-P

Overview

MP8130DJ-LF-P from Monolithic Power Systems is a rail-to-rail output, high-voltage operational amplifier in TSOT23-5 package, delivering 200kHz bandwidth, 10µA supply current, and 2.7V to 36V single-supply operation. It features input common-mode range to ground, unity-gain stability, and drives up to 1000pF capacitive loads-ideal for precision micropower sensor signal conditioning in battery-powered industrial monitors.

For engineers reviewing the MP8130DJ-LF-P datasheet, MP8130DJ-LF-P pinout, MP8130DJ-LF-P application, or MP8130DJ-LF-P equivalent, key selection criteria include ultra-low quiescent current, high-voltage rail-to-rail output swing, input-to-ground common-mode capability, and stable operation with capacitive loads in space-constrained analog front-ends.

Technical Context

The MP8130DJ-LF-P employs a high-voltage CMOS input stage enabling operation from 2.7V to 36V with input common-mode voltage extending to V– (ground). Its internal compensation ensures unity-gain stability without external components, even when driving ≥1000pF loads.

It achieves 200kHz –3dB bandwidth and 0.1V/µs slew rate at 10µA supply current, trading speed for ultra-low power-optimized for DC-coupled, low-frequency signal amplification where power budget and supply headroom are critical constraints.

FAQ

What is the maximum capacitive load the MP8130DJ-LF-P can drive without instability?

The MP8130DJ-LF-P is characterized to drive up to 1000pF capacitive loads while maintaining unity-gain stability, as confirmed in the datasheet's Electrical Characteristics table and Typical Performance plots. This eliminates the need for series isolation resistors in anti-aliasing filter designs, preserving signal fidelity and simplifying PCB layout.

Does the MP8130DJ-LF-P support true single-supply operation with input voltage down to ground?

Yes-the MP8130DJ-LF-P features an input common-mode voltage range that extends to V– (ground) under all supply conditions, enabling direct interface with grounded sensors like RTDs, thermistors, and shunt resistors without external bias networks or dual supplies.

What is the recommended power supply bypassing scheme for optimal PSRR performance?

Per the datasheet Application Information section, use a 10µF tantalum or aluminum electrolytic capacitor in parallel with a 0.1µF ceramic capacitor on both V+ and V– pins. Place both capacitors as close as possible to the device pins with short, low-inductance traces to achieve >80dB PSRR across the 2.7V–36V supply range.

Can the MP8130DJ-LF-P be used in inverting amplifier configurations?

Yes-the IN– (pin 4) and IN+ (pin 3) terminals support standard inverting and non-inverting configurations. The device's unity-gain stability and rail-to-rail output ensure predictable behavior in both topologies, including gain-of-100 or higher with appropriate feedback network selection.

Is the MP8130DJ-LF-P RoHS-compliant and lead-free?

Yes-the "-LF" suffix in MP8130DJ-LF-P explicitly denotes lead-free, RoHS-compliant packaging per EU Directive 2011/65/EU. The device uses matte tin lead finish and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) requirements.

What is the thermal resistance (θJA) of the TSOT23-5 package under standard PCB conditions?

The datasheet specifies θJA = 220°C/W for the TSOT23-5 package when mounted on a 1-inch square, 1-oz copper PCB-consistent with JEDEC test board standards. This value assumes no additional copper pour or thermal vias; adding thermal relief improves dissipation by up to 30%.
