Product details
Overview
AD8568ART-REEL7 from Analog Devices is a dual-channel rail-to-rail buffer amplifier optimized for LCD reference driver applications, featuring 4.5 V to 16 V single-supply operation, 10 mV max offset voltage, 6 V/µs slew rate, and 35 mA continuous output current per channel. It operates across –40°C to +85°C in a 6-lead SOT-23 package.
For engineers reviewing the AD8568ART-REEL7 datasheet, AD8568ART-REEL7 pinout, AD8568ART-REEL7 application, or AD8568ART-REEL7 equivalent, key selection criteria include rail-to-rail input/output swing, capacitive load drive stability up to 1 µF, low THD+N (<0.03% at 16 V), and thermal performance in compact portable electronics layouts.
Technical Context
The AD8568ART-REEL7 implements a high-voltage CBCMOS process architecture enabling true rail-to-rail input operation (–0.5 V to VS + 0.5 V) and output swing within 5 mV of rails at light loads. Its internal design supports stable unity-gain operation with 1 µF capacitive loads without external compensation.
It delivers 250 mA peak output current per channel and maintains 75 dB channel separation at 1 MHz, making it suitable for multi-buffered display biasing where crosstalk and transient settling are critical. Gain linearity remains ≤0.01% over 0.5 V to (VS – 0.5 V) output range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 16 V - Enables direct use with common LCD panel supplies including 5 V, 12 V, and 15 V rails. |
| Offset Voltage (Max) | 10 mV - Ensures <±10 mV DC error in precision reference buffering, critical for grayscale accuracy in LCD column drivers. |
| Slew Rate | 6 V/µs - Supports fast settling for dynamic contrast control signals and video-rate bias updates. |
| Continuous Output Current | 35 mA per channel - Drives typical LCD segment capacitance (e.g., 10–100 nF) with minimal droop under sustained load. |
| Input Voltage Range | –0.5 V to VS + 0.5 V - Allows input signals to exceed supply rails by 0.5 V, accommodating transient overshoot in system-level signal chains. |
| THD+N (16 V) | <0.03% - Minimizes harmonic distortion in analog video path applications such as TFT gate driver references. |
| Channel Separation | 75 dB at 1 MHz - Prevents crosstalk between adjacent buffered outputs in multi-line LCD bias networks. |
Pinout & Package
AD8568ART-REEL7 is housed in a 6-lead SOT-23 package (RT-6), measuring 2.90 mm × 1.60 mm × 1.15 mm, with gull-wing leads and JEDEC MO-178AB compliance. Thermal resistance θJA is 250°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting-capable buffered output for Channel A; rail-to-rail swing supports full-scale LCD reference generation. |
| 2 | V+ | Positive supply input; accepts 4.5 V to 16 V; decoupling capacitor required near pin for stability with capacitive loads. |
| 3 | IN A | Non-inverting input for Channel A; supports input beyond rails (–0.5 V to V+ + 0.5 V) for fault-tolerant signal routing. |
| 4 | GND | Analog ground reference; must be low-impedance connection to minimize PSRR degradation and output noise coupling. |
| 5 | OUT B | Inverting-capable buffered output for Channel B; electrically isolated from OUT A with 75 dB separation at 1 MHz. |
| 6 | IN B | Non-inverting input for Channel B; identical input specification to IN A, enabling matched dual-channel biasing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of supply headroom in single-supply LCD systems, eliminating level-shifting circuitry. |
| Stable with 1 µF capacitive loads | Permits direct driving of large-area LCD panel capacitance without external phase compensation or isolation resistors. |
| 35 mA continuous output per channel | Supports sustained current delivery into typical LCD column line impedances without thermal shutdown or gain compression. |
| No phase reversal | Guarantees monotonic output response during input overvoltage events, simplifying protection design in noisy environments. |
| Low THD+N (<0.03% at 16 V) | Maintains signal fidelity in analog video timing paths, reducing color banding and gamma curve distortion in display systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Lower supply range (2.7–6 V), 1.6 V/µs slew rate, 15 mA output drive - not rated for 16 V operation or 1 µF load stability. | Suitable only for low-voltage portable logic interfaces; cannot replace AD8568ART-REEL7 in 12 V/15 V LCD bias rails. | Select when operating below 6 V and driving <100 pF loads; avoid for high-voltage display applications. |
| OPA2350UA | Wider bandwidth (38 MHz), lower noise (7 nV/√Hz), but limited to 5.5 V max supply and unstable with >100 pF loads without compensation. | Better for high-speed signal conditioning, but lacks rail-to-rail input beyond rails and 16 V capability required for LCD reference buffers. | Prefer for audio or instrumentation amplification at ≤5.5 V; not a functional substitute for AD8568ART-REEL7's high-voltage, high-capacitance drive. |
Compared with TLV2462IDR and OPA2350UA, AD8568ART-REEL7 uniquely combines 16 V operation, rail-to-rail input beyond rails, and guaranteed 1 µF capacitive load stability - essential for unbuffered LCD column driver designs where layout space and external components must be minimized.

FAQ
What is the maximum capacitive load the AD8568ART-REEL7 can drive stably?
The AD8568ART-REEL7 is specified to remain stable with up to 1 µF capacitive loads without external compensation, as confirmed in the "Stable with 1 µF Loads" feature and TPC 21–22 small-signal overshoot data. This capability is critical for direct driving of large-area LCD panel capacitance and eliminates need for series isolation resistors in reference distribution networks.
Does the AD8568ART-REEL7 support input voltages beyond the supply rails?
Yes, the AD8568ART-REEL7 supports an input voltage range of –0.5 V to VS + 0.5 V, explicitly stated in the Electrical Characteristics table. This rail-overdrive capability allows safe interface with signals that transiently exceed the supply, such as DAC outputs with overshoot or system-level signals routed across multiple voltage domains.
What is the operating temperature range for the AD8568ART-REEL7?
The AD8568ART-REEL7 is rated for continuous operation from –40°C to +85°C, as documented in both the General Description and Ordering Guide sections. This industrial temperature range ensures reliability in portable electronics, outdoor displays, and communications infrastructure equipment exposed to ambient thermal cycling.
Is the AD8568ART-REEL7 pin-compatible with other members of the AD856x family?
No - the AD8568ART-REEL7 uses a 6-lead SOT-23 (RT-6) package, while AD8569 (4-channel) uses 10-lead MSOP and AD8570 (8-channel) uses 32-lead LFCSP or 20-lead TSSOP. Pin count, pinout, and package dimensions differ across the family; no pin-to-pin compatibility exists between AD8568ART-REEL7 and other variants.
What is the typical supply current per amplifier in the AD8568ART-REEL7?
The AD8568ART-REEL7 draws 700–850 µA per amplifier under no-load conditions at 25°C (ISY = 700 µA typ, 850 µA max), rising to 1 mA max over the full –40°C to +85°C range. This low quiescent current supports battery-powered portable display applications where standby power budget is constrained.
