Product details
Overview
EL5220TIYZ from Intersil is a dual-channel, rail-to-rail input-output operational amplifier optimized for TFT-LCD VCOM and static gamma buffering. It operates from 4.5V to 19V, delivers 12MHz bandwidth, 12V/µs slew rate, ±65mA continuous output current, and consumes only 550µA per amplifier. Its beyond-the-rails input capability and thermal protection make it suitable for high-voltage portable display systems.
For engineers reviewing the EL5220TIYZ datasheet, EL5220TIYZ pinout, EL5220TIYZ application, or EL5220TIYZ equivalent, key selection criteria include dual-channel rail-to-rail I/O performance at 12MHz, ±65mA drive capability under 19V supply, MSOP-8 package thermal pad connection to VS−, and verified use in TFT-LCD panel biasing with no phase reversal.
Technical Context
The EL5220TIYZ integrates two independent unity-gain-stable amplifiers with fully differential input stages enabling common-mode voltage operation 0.5V beyond both supply rails. Each channel supports single- or dual-supply configurations and features built-in thermal shutdown triggered at +165°C junction temperature.
Its output stage delivers rail-to-rail swing within 50mV of VS+ and VS− at ±5mA load, with short-circuit protection limiting sink/source current to ±200mA. Channel separation exceeds 85dB at 5MHz, ensuring minimal crosstalk in dual-buffer applications like VCOM and gamma control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 12MHz (–3dB), enabling full-spectrum signal fidelity for static gamma correction up to UXGA resolution panels. |
| Slew Rate | 12V/µs, supporting fast settling of large VCOM step transitions without distortion in active matrix LCDs. |
| Supply Range | 4.5V to 19V, allowing direct operation from 12V or ±9V supplies common in notebook and industrial display power rails. |
| Output Current | ±65mA continuous, sufficient to drive typical TFT-LCD panel capacitance (up to 10µF) with <500ns settling to 0.1%. |
| Input Offset Drift | 5µV/°C (MSOP package), ensuring stable DC bias accuracy across –40°C to +85°C ambient operating range. |
| Thermal Resistance | θJA = 170°C/W (MSOP-8), requiring PCB thermal pad connection to VS− plane to maintain TJ < 150°C at 65mA load. |
| Operating Temperature | –40°C to +85°C ambient, validated for use in consumer electronics notebooks, touch-screen displays, and portable instrumentation. |
Pinout & Package
EL5220TIYZ is packaged in an 8-lead MSOP (M8.118A) with exposed thermal pad electrically connected to VS−. The package requires soldering the thermal pad to a VS− copper plane via multiple vias for optimal thermal performance and stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUTA | Amplifier A output | Drives first VCOM or gamma node; must be decoupled with 0.1µF capacitor near pin for high-frequency stability. |
| VINA− | Amplifier A inverting input | Accepts feedback network; immune to phase reversal even when driven 0.5V beyond VS− or VS+. |
| VINA+ | Amplifier A non-inverting input | Receives reference voltage (e.g., DAC output); supports common-mode range from VS− −0.5V to VS+ +0.5V. |
| VS− | Negative power supply / thermal pad reference | Must connect thermal pad directly to VS− PCB plane; serves as return path for both amplifiers and thermal dissipation node. |
| VINB+ | Amplifier B non-inverting input | Accepts second reference (e.g., gamma tap); identical input specs to VINA+, enabling matched dual-channel biasing. |
| VINB− | Amplifier B inverting input | Configured for unity-gain buffer or closed-loop gain; shares same ESD and CMIR specs as VINA−. |
| VOUTB | Amplifier B output | Drives secondary VCOM/gamma node; channel separation ≥85dB prevents interference between A/B outputs at 5MHz. |
| VS+ | Positive power supply | Accepts up to +19V; requires 4.7µF bulk + 0.1µF ceramic bypass to ground, placed within 5mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Beyond-the-rails input | Input common-mode range extends 0.5V beyond VS− and VS+, eliminating need for level-shifting in high-side reference circuits. |
| Rail-to-rail output | Swings within 50mV of VS+ and VS− at ±5mA, maximizing dynamic range for analog gamma correction without headroom loss. |
| Thermal shutdown | Automatically disables outputs at +165°C junction temperature and recovers after +15°C cooldown, preventing latch-up in sustained overload. |
| Unity-gain stable | Operates reliably with gain = 1 without external compensation, simplifying layout for VCOM buffer and gamma follower designs. |
| Pb-free RoHS compliance | Matte tin (e3) termination compatible with SnPb and Pb-free reflow profiles, meeting IPC/JEDEC J-STD-020 MSL Level 1 requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV822MM/NOPB | Lower 5.5MHz bandwidth, 2.5V/µs slew rate, max 5.5V supply, no beyond-the-rails input. | Suitable for low-speed portable audio or sensor interfaces but cannot replace EL5220TIYZ in 12MHz VCOM or gamma applications. | Select LMV822MM/NOPB only for cost-sensitive, low-bandwidth designs where 12MHz performance and 19V operation are unnecessary. |
| AD8602ARMZ | 10MHz bandwidth, 5V/µs slew rate, 6V max supply, rail-to-rail output only (not input), lower 650µA supply current. | Valid for precision low-voltage instrumentation but lacks high-voltage capability and beyond-the-rails input needed for TFT-LCD biasing. | Choose AD8602ARMZ for sub-6V, low-noise (<12nV/√Hz) applications where EL5220TIYZ's 19V range and 12V/µs slew are over-spec. |
Compared with LMV822MM/NOPB and AD8602ARMZ, EL5220TIYZ uniquely supports 12MHz bandwidth, 12V/µs slew rate, and 4.5–19V operation with true rail-to-rail I/O and beyond-the-rails input-making it irreplaceable in high-voltage display biasing where dynamic response and supply flexibility are critical.

FAQ
What is the maximum supply voltage for EL5220TIYZ?
The EL5220TIYZ supports a maximum supply voltage of +19V between VS+ and VS−, with absolute maximum rating of +19.8V. This allows reliable operation from standard 12V, 15V, or ±9V rails commonly used in display power architectures. Exceeding +19.8V risks permanent damage per Absolute Maximum Ratings on page 3 of FN6892 Rev 0.00.
Does EL5220TIYZ require external compensation for unity-gain stability?
No, EL5220TIYZ is internally compensated and unity-gain stable per datasheet page 1 and Features list. It operates reliably with gain = 1 without external capacitors or resistors, simplifying VCOM buffer and gamma follower designs. Stability is verified across all supply voltages (4.5V–19V) and load conditions up to 10kΩ || 8pF.
How should the thermal pad on EL5220TIYZ be connected?
The exposed thermal pad on EL5220TIYZ (MSOP-8 package) must be soldered to a VS− copper plane using ≥4 thermal vias. Per Pin Descriptions on page 2, the pad is electrically connected to VS− and functions as both heat sink and return path. Failure to connect it causes θJA to rise from 170°C/W to >210°C/W, risking thermal shutdown at ≤40mA load.
Can EL5220TIYZ drive capacitive loads without oscillation?
EL5220TIYZ can drive moderate capacitive loads (≤50pF) stably in unity-gain configuration, but larger loads cause peaking and potential instability. Per Applications Information on page 12, a series output resistor (1–10Ω) or RC snubber is recommended for loads >100pF. Layout best practices-short traces, ground plane, and local 0.1µF bypass-are mandatory for stability.
What is the guaranteed output current capability of EL5220TIYZ?
EL5220TIYZ guarantees ±65mA continuous output current per amplifier, as specified in Absolute Maximum Ratings and Electrical Specifications tables (pages 3–5). While short-circuit current reaches ±200mA, sustained operation above ±65mA risks exceeding junction temperature limits due to internal metal interconnect limitations, per page 11 "Output Current" section.
