Product details
Overview
AD8567ACPZ-REEL7 from Analog Devices is a quad-channel, 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 per channel, achieves 6 V/µs slew rate, and maintains rail-to-rail output swing with <10 mV offset voltage. It is qualified for automotive infotainment systems and industrial LCD panels.
For engineers reviewing the AD8567ACPZ-REEL7 datasheet, AD8567ACPZ-REEL7 pinout, AD8567ACPZ-REEL7 application, or AD8567ACPZ-REEL7 equivalent, this page provides verified technical context, package-specific thermal pad guidance, real-world LCD panel drive capability, and validated alternatives for VCOM driver design and high-capacitive-load buffering.
Technical Context
The AD8567ACPZ-REEL7 uses a dual PNP bipolar input stage with diode protection networks enabling true rail-to-rail input operation across −0.5 V to VS + 0.5 V. Its complementary common-source output stage supports rail-to-rail swing while sourcing/sinking up to 250 mA peak current per channel.
It features unity-gain stability with ≥1 µF capacitive loads, exhibits no phase reversal under overvoltage conditions, and maintains >65° phase margin at 10 pF load. The LFCSP package includes an exposed thermal pad that must be connected to V+ (Pin 3) for safe thermal performance and optimal electrical behavior.
Key Specifications

Pinout & Package
The AD8567ACPZ-REEL7 is housed in a 16-lead LFCSP (CP-16-23) package with 4 mm × 4 mm body and 0.75 mm height. The exposed thermal pad must be soldered to a PCB copper area electrically connected to V+ (Pin 3); grounding it degrades performance.

Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Operates with inputs down to −0.5 V and outputs within 5 mV of rails - eliminates level-shifting in single-supply LCD systems. |
| High capacitive load drive | Stable with ≥1 µF load at unity gain - directly drives large-area LCD panels without external compensation. |
| No phase reversal | Immune to output polarity inversion during input overvoltage - prevents catastrophic latch-up in noisy display environments. |

Applications
| LCD VCOM Driver | Grayscale Reference Buffer |
|---|---|
Use Scenario: Driving the common electrode (VCOM) of TFT-LCD panels requiring precise AC-biased DC voltage with fast transient response. IC Role / Device Role / Timing Role: Quad op-amp provides four independent, synchronized VCOM outputs for segmented or dual-display architectures.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV324QDRQ1 | Lower slew rate (1 V/µs), higher offset (3 mV typ), 5.5 V max supply - not suitable for 16 V LCD rails. | Limited to low-voltage portable displays; cannot replace AD8567ACPZ-REEL7 in 12–16 V VCOM systems. | Select only if supply is ≤5.5 V and peak current demand <10 mA. |
| TSV914IQDT | Higher GBW (8 MHz), lower quiescent current (80 µA), but only 5.5 V max supply and 60 mA peak output. | Applicable for low-power grayscale buffers in compact displays, but lacks high-voltage drive capability for large panels. | Prefer for space-constrained, battery-powered UIs where 16 V operation is unnecessary. |
Compared with LMV324QDRQ1 and TSV914IQDT, the AD8567ACPZ-REEL7 uniquely supports 16 V single-supply operation, delivers 250 mA peak current, and maintains stability with >1 µF loads - making it irreplaceable for high-performance LCD VCOM driver designs.

FAQ
What is the maximum continuous output current per channel for the AD8567ACPZ-REEL7?
The AD8567ACPZ-REEL7 delivers 35 mA continuous output current per amplifier channel. This rating applies across the full −40°C to +85°C operating temperature range and ensures stable operation into typical LCD panel impedances without thermal derating. Exceeding this limit continuously may trigger thermal shutdown or degrade long-term reliability.
Does the AD8567ACPZ-REEL7 require external compensation when driving large capacitive loads?
No, the AD8567ACPZ-REEL7 is unity-gain stable with capacitive loads up to at least 1 µF, as confirmed in the datasheet's Typical Performance Characteristics. This eliminates the need for external compensation networks in LCD VCOM driver applications, simplifying layout and improving system reliability.
How must the exposed thermal pad on the AD8567ACPZ-REEL7 LFCSP package be connected?
The exposed thermal pad on the AD8567ACPZ-REEL7 must be soldered to a PCB copper area electrically connected to Pin 3 (V+). Connecting it to ground or leaving it floating degrades electrical performance and compromises thermal dissipation. Vias should be placed under the pad to route heat to inner layers or ground planes.
Is the AD8567ACPZ-REEL7 suitable for automotive applications?
Yes, the AD8567ACPZ-REEL7 is qualified for automotive applications and specified over the −40°C to +85°C temperature range. While not AEC-Q100 certified as a standalone part, its electrical specifications, thermal design, and qualification testing align with automotive infotainment display requirements.
What is the input voltage range specification for the AD8567ACPZ-REEL7?
The AD8567ACPZ-REEL7 supports an input voltage range of −0.5 V to VS + 0.5 V, enabling true rail-to-rail input operation beyond the supply rails. This allows direct interfacing with signals that exceed V+ or go below V−, a key requirement for fault-tolerant LCD biasing circuits.
