Product details
Overview
MP5220DK-LF-P from Monolithic Power Systems is a dual-channel, high-speed, rail-to-rail input-output operational amplifier optimized for TFT-LCD voltage reference buffering. It operates from ±1.6V to ±9.0V supplies, delivers 20MHz –3dB bandwidth, 45V/µs slew rate, and 50mA output drive per channel, with output swing within 100mV of both rails. Used in portable display driver circuits requiring fast settling and wide dynamic range.
For engineers reviewing the MP5220DK-LF-P datasheet, MP5220DK-LF-P pinout, MP5220DK-LF-P application, or MP5220DK-LF-P equivalent, key selection criteria include rail-to-rail I/O capability at ±9V supply, 50mA output current per amplifier, 20MHz bandwidth under 10kΩ/10pF load, and MSOP-8 package compatibility with space-constrained TFT-LCD timing control modules.
Technical Context
The MP5220 employs dual-input-stage architecture: a PNP pair for inputs from VS− −0.5V to VS+ −1V, and an NPN pair extending input range to VS+ +0.5V. This enables true rail-to-rail input operation but introduces transition-region distortion near supply rails.
Output stage supports ±50mA continuous sourcing/sinking, with reduced drive capability when output voltage approaches either rail. Phase margin is 50° at unity gain with 10kΩ//10pF load, ensuring stable operation in closed-loop configurations including ADC buffers and active filters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±1.6V to ±9.0V - supports standard ±5V and ±9V display bias rails without level-shifting |
| –3dB Bandwidth | 20MHz - enables accurate amplification of fast pixel clock harmonics up to ~6MHz fundamental |
| Slew Rate | 45V/µs - ensures ≤500ns settling to 0.1% for 2V step, critical for high-resolution LCD column drivers |
| Input Common-Mode Range | VS− −0.5V to VS+ +0.5V - accepts signals beyond supply rails, simplifying interface with DAC outputs |
| Output Swing (RL = 10kΩ) | Within 100mV of VS+ and VS− - maximizes usable dynamic range in single-supply or split-supply display reference paths |
| Supply Current per Amplifier | 1.6mA - enables dual-channel operation at <3.3mA total, suitable for battery-powered portable displays |
| Channel Separation | 70dB at 5MHz - prevents crosstalk between dual-channel LCD gamma correction or VCOM control paths |
Pinout & Package
MP5220DK-LF-P is housed in an 8-pin MSOP package (JEDEC MO-187, variation AA), with exposed thermal pad for improved power dissipation in compact display modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VINA− | Inverting input of Channel A - referenced to internal differential pair; requires matched layout for low offset drift |
| 2 | VINA+ | Non-inverting input of Channel A - accepts rail-to-rail common-mode signals up to VS+ +0.5V |
| 3 | VS− | Negative supply rail - must be decoupled with ≥0.1µF ceramic capacitor placed <2mm from pin |
| 4 | VOUTA | Output of Channel A - capable of ±50mA drive; output impedance drops near rails, affecting linearity |
| 5 | VOUTB | Output of Channel B - independent output stage; shares no internal nodes with Channel A |
| 6 | VS+ | Positive supply rail - requires separate 0.1µF + 10µF parallel decoupling for high-frequency PSRR |
| 7 | VINB+ | Non-inverting input of Channel B - electrically isolated from Channel A inputs; same rail-to-rail range |
| 8 | VINB− | Inverting input of Channel B - layout symmetry with Pin 1 recommended to minimize inter-channel mismatch |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with dual differential pairs | Enables direct interfacing with 0–5V DAC outputs and ±5V reference sources without external level shifters |
| 45V/µs slew rate with 20MHz bandwidth | Supports <500ns settling for 2V steps, meeting timing requirements of QXGA (2048×1536) LCD column drivers |
| ±50mA output drive per channel | Drives 100Ω loads directly, eliminating need for external buffer transistors in VCOM calibration circuits |
| 70dB channel separation at 5MHz | Maintains gamma curve fidelity across dual-channel RGB timing paths without cross-color interference |
| Unity-gain stable with 10kΩ//10pF load | Permits use as unity-gain buffer in ADC front-ends without external compensation components |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, high-speed, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8662ARZ | Lower slew rate (12V/µs), lower bandwidth (16MHz), higher supply current (2.4mA/channel) | Limited to ≤1MHz pixel clock harmonics; less suitable for QXGA+ timing-critical VCOM paths | Prefer where ultra-low input bias current (1pA) outweighs speed requirements |
| LMH6643MMX | Higher slew rate (130V/µs), wider bandwidth (72MHz), but not rail-to-rail input (CMIR = VS− to VS+ −1.2V) | Requires level-shifting for DAC outputs near VS+; unsuitable for direct 0–5V interface in gamma buffers | Prefer where extreme speed dominates over input range, e.g., video signal reconstruction |
Compared with AD8662ARZ and LMH6643MMX, MP5220DK-LF-P uniquely balances ±9V operation, rail-to-rail I/O, 20MHz bandwidth, and 50mA drive in an MSOP-8 package-making it optimal for integrated TFT-LCD timing IC support rather than general-purpose or high-precision instrumentation roles.

FAQ
What is the maximum safe operating supply voltage for MP5220DK-LF-P?
The absolute maximum supply voltage between VS+ and VS− is +22V. However, the recommended operating range is ±1.6V to ±9.0V. Operation above ±9.0V risks exceeding junction temperature limits and degrading long-term reliability, especially under 50mA load conditions.
Does MP5220DK-LF-P require external compensation for unity-gain stability?
No. MP5220DK-LF-P is internally compensated and unity-gain stable with capacitive loads up to 10pF and resistive loads ≥10kΩ. For heavier capacitive loads (>20pF), a small series resistor (10–50Ω) at the output is recommended to maintain phase margin.
Can MP5220DK-LF-P drive a 100Ω load continuously?
Yes - each channel can source or sink up to ±50mA continuously. At ±5V supply, driving a 100Ω load (±50mA) results in ~250mW per channel. Thermal design must ensure junction temperature remains ≤125°C, requiring adequate PCB copper area or thermal vias beneath the MSOP-8 exposed pad.
How does input stage switching affect distortion in MP5220DK-LF-P?
At input voltages near VS+ −1V, the device transitions from the PNP to NPN input pair. This causes measurable THD increase (>0.1%) and CMRR degradation. For lowest distortion, keep input signals within VS− +0.5V to VS+ −1.2V - a 4.8V window at ±5V supply.
Is the MSOP-8 package of MP5220DK-LF-P RoHS-compliant and lead-free?
Yes - the "-LF" suffix denotes lead-free, RoHS-compliant packaging. The MSOP-8 body uses matte tin lead finish, and the device meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) for standard SMT assembly processes.
What decoupling is required for optimal PSRR performance?
Each supply rail requires a 0.1µF X7R ceramic capacitor placed ≤2mm from its respective pin, plus a 10µF tantalum or aluminum polymer capacitor within 5mm. This dual-capacitor approach maintains low impedance from 10kHz to 100MHz, improving PSRR by >20dB above 1MHz.
Does MP5220DK-LF-P support single-supply operation?
Yes - it operates with a single 3.2V to 18V supply (e.g., 12V) referenced to ground. In this mode, input common-mode range is 0.5V to 12.5V, and output swings within 100mV of ground and 12V. Ground must be treated as VS−, and all signals referenced accordingly.
