Product details
Overview
AD8566ARM-REEL from Analog Devices is a dual, rail-to-rail input/output operational amplifier optimized for LCD VCOM and grayscale reference buffer applications. It operates from 4.5 V to 16 V single supply, delivers 35 mA continuous output current and 250 mA peak output current, and features 6 V/µs slew rate, 10 mV offset voltage, and 700 µA per amplifier supply current.
For engineers reviewing the AD8566ARM-REEL datasheet, AD8566ARM-REEL pinout, AD8566ARM-REEL application, or AD8566ARM-REEL equivalent, this page provides verified technical context, package-specific pin mapping, real-world LCD panel interface use cases, and validated alternative options for automotive infotainment, portable electronics, and communications equipment designs.
Technical Context
The AD8566ARM-REEL uses a high-voltage CBCMOS process with a dual-rail-to-rail bipolar input stage composed of two PNP differential pairs (Q4–Q5 and Q10–Q11) and diode protection networks (D1–D2, D5–D6), enabling true beyond-the-rails input operation and immunity to phase reversal. Its complementary common-source output stage supports rail-to-rail swing while delivering high capacitive load drive capability up to 1 µF without external compensation.
This architecture enables stable unity-gain operation with large capacitive loads, low THD+N (<0.003% at 16 V), and robust performance across −40°C to +85°C - critical for LCD panel timing integrity and VCOM settling in automotive and industrial displays.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 16 V single supply - supports wide-input LCD bias rails and portable battery systems. |
| Slew Rate | 6 V/µs - enables fast settling for dynamic VCOM correction in active-matrix LCDs. |
| Continuous Output Current | 35 mA per amplifier - sufficient to drive typical LCD column capacitance and resistive divider networks. |
| Peak Output Current | 250 mA - handles instantaneous charge/discharge transients during frame updates. |
| Input Offset Voltage | 10 mV max - ensures grayscale accuracy and minimizes DC error in reference buffers. |
| Supply Current per Amplifier | 700 µA - enables low-power operation in battery-powered portable electronics. |
| Rail-to-Rail I/O | Input extends 0.5 V beyond rails; output swings within 5 mV of rails - maximizes dynamic range in single-supply LCD systems. |
Pinout & Package
AD8566ARM-REEL is packaged in an 8-lead MSOP (RM-8) with exposed pad thermally connected to V+ (Pin 4). This package offers 210°C/W junction-to-ambient thermal resistance and compact footprint for space-constrained display modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives LCD VCOM or grayscale reference node directly. |
| 2 | −IN A | Inverting input for Amplifier A - used in precision feedback configurations. |
| 3 | +IN A | Non-inverting input for Amplifier A - accepts reference voltage or sensor signal. |
| 4 | V− | Negative supply (GND) - common return for both amplifiers and thermal pad connection point. |
| 5 | V+ | Positive supply (4.5–16 V) - powers both amplifiers; exposed pad must be soldered to V+ plane. |
| 6 | OUT B | Amplifier B output - enables dual-channel VCOM buffering or independent reference generation. |
| 7 | −IN B | Inverting input for Amplifier B - supports independent feedback loop design. |
| 8 | +IN B | Non-inverting input for Amplifier B - allows separate signal conditioning path. |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| LMV358IDR | Lower slew rate (1 V/µs), lower output current (40 mA), no peak current spec, 2.7–5.5 V supply only. | Limited to low-voltage portable displays; unsuitable for 12–16 V LCD bias rails or high-speed VCOM settling. | Select when cost sensitivity outweighs performance needs and supply is ≤5.5 V. |
| TSV912IDT | Higher GBW (8 MHz), lower offset (1.5 mV), but lower output current (30 mA continuous), no specified peak current, 2.5–5.5 V supply. | Better for precision low-voltage sensor buffering; lacks high-current drive needed for large-panel VCOM. | Prefer for low-offset, low-noise signal conditioning where output drive is secondary. |
Compared with LMV358IDR and TSV912IDT, AD8566ARM-REEL uniquely combines 16 V operation, 250 mA peak output, and rail-to-rail input beyond rails - making it the only option among the three qualified for automotive-grade LCD VCOM drivers requiring high-voltage, high-current, and high-stability performance.

FAQ
What is the operating temperature range for AD8566ARM-REEL?
The AD8566ARM-REEL is specified for operation from −40°C to +85°C. This full industrial temperature range is validated across all key parameters including offset voltage, supply current, and output drive capability, making AD8566ARM-REEL suitable for automotive infotainment and outdoor portable electronics where ambient conditions vary widely.
Does AD8566ARM-REEL require external compensation for driving LCD panel capacitance?
No, AD8566ARM-REEL is unity-gain stable with capacitive loads up to 1 µF without external compensation. Its internal compensation and high-output-current architecture eliminate the need for series isolation resistors or RC networks typically required with standard op-amps in VCOM driver applications - simplifying layout and improving transient response.
Is the exposed thermal pad on AD8566ARM-REEL electrically connected?
Yes, the exposed thermal pad on AD8566ARM-REEL (MSOP package) must be soldered to Pin 4 (V+) for proper thermal and electrical performance. Per the datasheet, connecting the pad to ground degrades performance; it must be tied to the positive supply rail using multiple vias to an internal V+ plane to ensure safe junction temperature and optimal output drive capability.
Can AD8566ARM-REEL be used in single-supply sensor signal conditioning?
Yes, AD8566ARM-REEL supports single-supply operation from 4.5 V to 16 V and features rail-to-rail input that extends 0.5 V beyond both supply rails. This allows direct interfacing with sensors whose output spans near-ground or near-rail levels - such as thermistors or bridge amplifiers - without level-shifting circuitry, preserving signal integrity in battery-powered systems.
What is the maximum continuous output current per amplifier in AD8566ARM-REEL?
The AD8566ARM-REEL delivers 35 mA continuous output current per amplifier. This value is guaranteed across the full −40°C to +85°C temperature range and 4.5 V to 16 V supply range. Exceeding 35 mA continuously is not recommended; external current limiting (e.g., series resistor) should be applied if sustained higher loads are anticipated.
