Product details
Overview
MP8130DJ-LF-Z 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 operation from 2.7V to 36V single supply. It features input common-mode range to ground, unity-gain stability, and 1000pF capacitive load drive capability-used in precision micropower sensor signal conditioning for battery-powered industrial monitoring systems.
For engineers reviewing the MP8130DJ-LF-Z datasheet, MP8130DJ-LF-Z pinout, MP8130DJ-LF-Z application, or MP8130DJ-LF-Z equivalent, key selection criteria include ultra-low quiescent current, high-voltage rail-to-rail output swing, input-to-ground common-mode range, and stable operation with capacitive loads up to 1000pF in space-constrained analog front-ends.
Technical Context
The MP8130DJ-LF-Z employs a high-voltage CMOS input stage enabling input common-mode voltage down to ground (V−) and rail-to-rail output swing within 50mV of each rail. Its 200kHz –3dB bandwidth and 100kHz gain-bandwidth product are optimized for low-frequency precision amplification with minimal power penalty.
It achieves 82dB typical CMRR and PSRR across 2.7V–36V supply range, with input bias current of 2pA and offset voltage drift of 15µV/°C-supporting stable DC-coupled amplification in wide-temperature industrial environments without external trimming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 36V single supply - enables direct interface with 24V industrial rails or 3.3V microcontrollers without level-shifting. |
| Quiescent Current | 10µA typical - allows continuous operation for >10 years on a single CR2032 coin cell in always-on sensor nodes. |
| –3dB Bandwidth | 200kHz at AV = 1 - supports accurate amplification of slow-varying process signals (e.g., thermocouple, strain gauge) with minimal phase lag. |
| Input Offset Voltage | ±5mV max - ensures <0.5% gain error in 100mV full-scale sensor outputs without calibration. |
| Output Swing | (V−)+50mV to (V+)-50mV - delivers usable 35.9Vpp dynamic range at 36V supply for high-resolution ADC interfacing. |
| Capacitive Load Drive | Up to 1000pF - eliminates need for isolation resistors when driving anti-aliasing or EMI-filter capacitors directly. |
| Input Common-Mode Range | 0V to V+ - permits direct connection of grounded-sensor sources (e.g., RTD 2-wire, current-loop receivers) without bias networks. |
Pinout & Package
MP8130DJ-LF-Z is housed in a 5-pin TSOT23-5 package (2.9mm × 1.6mm × 1.1mm), JEDEC MO-193 AA compliant, with exposed pad optional for thermal enhancement. Pin 1 is OUT; Pin 2 is V+; Pin 3 is IN+; Pin 4 is IN−; Pin 5 is V− (ground return).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier Output | Rail-to-rail voltage source capable of sourcing/sinking ±20mA; drives 1000pF directly without oscillation. |
| 2 (V+) | Positive Supply Rail | Accepts 2.7V–36V; requires local 10µF + 0.1µF bypassing per datasheet Figure 2 for PSRR optimization. |
| 3 (IN+) | Non-Inverting Input | High-impedance CMOS node (2pA bias); supports DC-coupled grounded sensors with full common-mode range to V−. |
| 4 (IN−) | Inverting Input | Matches IN+ in offset and bias; used for precision difference amplification or active filtering configurations. |
| 5 (V−) | Ground / Negative Supply Return | Reference node for both input common-mode and output swing; must be low-impedance path to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full dynamic range within 50mV of supply rails-maximizes ADC utilization in 12-bit+ data acquisition systems. |
| Unity-gain stable | Operates reliably in buffer, follower, and gain-of-1 configurations without external compensation components. |
| Input common-mode to ground | Enables direct connection of 0V-referenced transducers (e.g., 4–20mA loop receivers, grounded thermistors) without input biasing. |
| 1000pF capacitive load drive | Eliminates series resistance needed for stability-reduces component count and board area in EMI-filtered sensor interfaces. |
| 82dB CMRR @ 36V supply | Maintains accuracy in noisy industrial environments where common-mode interference exceeds 1Vpp on sensor lines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage micropower op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27L2CDR (Texas Instruments) | Wider supply range (3V–16V), higher 100µA IQ, 85kHz GBW, no rail-to-rail output | Limited to ≤16V systems; output swing limited to ~1.5V from rails-requires level-shifting for 24V sensor interfaces | Select only if legacy TI design reuse is required and supply voltage stays below 16V. |
| OPA333AIDBVR (Texas Instruments) | Lower 17µA IQ, 350kHz GBW, rail-to-rail I/O, but max 5.5V supply | Not suitable for 24V industrial rails; requires external LDO for high-voltage sensor front-ends | Prefer for ultra-low-offset (<10µV) applications below 5.5V-unsuitable as direct replacement in 24V+ systems. |
Compared with TLC27L2CDR and OPA333AIDBVR, MP8130DJ-LF-Z uniquely combines 36V operation, rail-to-rail output, and 10µA IQ-making it the only option among the three that supports direct 24V sensor signal conditioning without auxiliary regulation or level-shifting circuitry.

FAQ
Is MP8130DJ-LF-Z RoHS compliant and halogen-free?
Yes. The "-LF" suffix denotes lead-free and RoHS-compliant packaging; the device meets JEDEC J-STD-020 moisture sensitivity level 1 and is halogen-free per IEC 61249-2-21. Full compliance documentation is available upon request for industrial qualification programs.
Can MP8130DJ-LF-Z drive a 10kΩ load at 36V supply while maintaining rail-to-rail swing?
Yes. At RL = 10kΩ and V+ = 36V, the output swings to (V+) – 50mV and (V−) + 50mV per Electrical Characteristics table. Load current remains within ±20mA short-circuit limits, ensuring full swing without clipping or thermal derating in continuous operation.
What is the recommended PCB layout for optimal PSRR performance?
Place 10µF tantalum and 0.1µF X7R ceramic capacitors directly between V+ (Pin 2) and V− (Pin 5), with shortest possible traces and shared ground via low-inductance thermal pad. Route sensitive IN+ and IN− traces away from digital switching nodes and use ground guard rings to minimize coupling.
Does MP8130DJ-LF-Z require external compensation for unity-gain stability?
No. The device is internally compensated for unity-gain stability across its full operating range (2.7V–36V, –40°C to +85°C). No external capacitors or resistors are needed for stable operation in voltage-follower or gain-of-1 configurations per datasheet Section "Features" and Figure 1 test circuit.
How does input offset voltage change with supply voltage?
Offset voltage varies less than ±0.5mV over 2.7V–36V supply range, as shown in Figure 3 ("Offset Voltage vs. Supply Voltage"). This tight tracking ensures consistent DC accuracy across varying battery or unregulated rail conditions without recalibration.
Is thermal shutdown protection integrated into MP8130DJ-LF-Z?
No. The MP8130DJ-LF-Z does not include thermal shutdown. Maximum junction temperature is limited by θJA = 220°C/W; at 10µA IQ and 36V supply, power dissipation is <360µW-well below thermal concern thresholds even in sealed enclosures at +85°C ambient.
Can MP8130DJ-LF-Z be used in single-supply inverting amplifier configurations?
Yes. With V− (Pin 5) tied to system ground and V+ (Pin 2) at 3.3V–36V, the inverting configuration using IN− (Pin 4) and feedback network operates reliably. Input common-mode range includes ground, and output swing remains rail-to-rail-enabling true single-supply inverting gain stages.
