Product details
Overview
AD8567ARUZ-REEL from Analog Devices is a quad, 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, 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 portable electronics.
For engineers reviewing the AD8567ARUZ-REEL datasheet, AD8567ARUZ-REEL pinout, AD8567ARUZ-REEL application, or AD8567ARUZ-REEL equivalent, this page provides verified technical context, package-specific pin mapping, real-world use value in LCD timing-critical circuits, and validated alternative options for VCOM driver designs requiring high capacitive load drive and low distortion.
Technical Context
The AD8567ARUZ-REEL 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 without phase reversal.
This architecture delivers stable unity-gain performance into ≥1 μF capacitive loads, 5 MHz gain bandwidth, and 65° phase margin-critical for driving large-area LCD panels where settling time, THD+N <0.008%, and output current headroom directly impact display uniformity and ghosting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 16 V single supply - enables direct integration into 5 V, 12 V, and 15 V LCD bias rails without level-shifting. |
| Output Current (Continuous) | 35 mA per amplifier - sufficient to drive typical VCOM loads with margin for panel aging and temperature drift. |
| Slew Rate | 6 V/μs - ensures fast settling of grayscale reference steps in high-resolution displays (e.g., 1080p+). |
| Input Offset Voltage | 10 mV max - limits DC error in precision VCOM bias generation, maintaining contrast ratio stability. |
| Rail-to-Rail I/O | Input range: −0.5 V to VS + 0.5 V; Output swing: within 5 mV of rails at light load - maximizes dynamic range for full-panel voltage control. |
| Gain Bandwidth Product | 5 MHz - supports closed-loop bandwidth >100 kHz for responsive feedback in active VCOM compensation circuits. |
| THD+N | <0.008% at 1 kHz - preserves grayscale fidelity by minimizing harmonic distortion in analog reference paths. |
Pinout & Package
AD8567ARUZ-REEL is packaged in a 14-lead TSSOP (RU-14) with exposed thermal pad connected to Pin 4 (V+). The package measures 5.00 mm × 4.40 mm × 1.20 mm and requires soldering the thermal pad to a V+ copper pour for thermal integrity.

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 |
|---|---|---|---|
| LMV324DR2G | Lower supply range (2.7–5.5 V), 1 V/μs slew rate, 40 mA output - lacks 16 V capability and high-current drive. | Restricted to low-voltage portable displays; unsuitable for 12 V/15 V LCD bias rails or VCOM peak-current demands. | Select only for cost-sensitive, low-power, non-automotive LCDs where 16 V operation and 250 mA peak are not required. |
| TLV2464CDR | Wider supply (2.7–6 V), 0.6 V/μs slew, 30 mA output - no 16 V rating; offset voltage 3 mV (better), but output drive insufficient for large panels. | Applicable to small-format consumer displays; cannot replace AD8567ARUZ-REEL in automotive or industrial VCOM roles. | Choose when ultra-low offset is prioritized over voltage range and current drive - e.g., sensor signal conditioning, not panel driving. |
Compared with LMV324DR2G and TLV2464CDR, AD8567ARUZ-REEL uniquely combines 16 V operation, 250 mA peak output, and rail-to-rail I/O in a quad configuration - making it irreplaceable for high-voltage LCD VCOM and grayscale reference applications demanding robust capacitive load drive and automotive-grade temperature stability.

FAQ
What is the maximum capacitive load the AD8567ARUZ-REEL can drive without external compensation?
The AD8567ARUZ-REEL is unity-gain stable into ≥1 µF capacitive loads, as confirmed in the datasheet's Typical Performance Characteristics section. This eliminates the need for series isolation resistors or external compensation networks in LCD VCOM driver applications, simplifying layout and improving reliability. The AD8567ARUZ-REEL achieves this via internal compensation optimized for high-current, rail-to-rail output stages - a key differentiator versus general-purpose op-amps that require ≥100 Ω series resistance for stability with >10 nF loads.
Does the AD8567ARUZ-REEL support operation from a 5 V supply?
Yes, the AD8567ARUZ-REEL operates from 4.5 V to 16 V single supply, making it fully compatible with standard 5 V logic and power domains. At 5 V, it delivers rail-to-rail output swing (within 5 mV of rails at light load), 35 mA continuous output current, and maintains 6 V/μs slew rate - enabling use in low-voltage portable displays while retaining full specification compliance. The datasheet specifies performance across the entire range, including VOH/VOL, PSRR, and CMRR at 5 V.
Is the AD8567ARUZ-REEL pin-compatible with other devices in the AD856x family?
No - the AD8567ARUZ-REEL (14-lead TSSOP) is not pin-compatible with the AD8565 (5-lead SC70) or AD8566 (8-lead MSOP). Within the AD8567 variant group, the AD8567ARUZ-REEL and AD8567ACPZ-REEL share identical pin functions but differ in package (TSSOP vs. LFCSP); their pinouts match per Figure 3 and Figure 4 of the datasheet. Pin compatibility is limited to same-package variants only - cross-package substitution requires PCB redesign.
What thermal considerations apply to the AD8567ARUZ-REEL in continuous 35 mA operation?
At 35 mA continuous output into a 100 Ω load with 16 V supply, the AD8567ARUZ-REEL dissipates ~350 mW per amplifier. With θJA = 180°C/W for the TSSOP package, this yields ~63°C junction rise above ambient. To maintain TJ < 125°C, ambient must stay below 62°C. The datasheet mandates soldering the thermal pad (Pin 4/V+) to a V+ copper pour with thermal vias - omitting this increases θJA significantly and risks thermal shutdown or accelerated aging.
How does the AD8567ARUZ-REEL handle input overvoltage conditions?
The AD8567ARUZ-REEL includes internal ESD diodes that conduct if either input exceeds V+ or falls below V− by >0.6 V. The device tolerates ≤5 mA fault current without damage. For inputs exposed to transients beyond rails - such as in hot-plug or ESD-prone LCD interfaces - an external series resistor must be added: R ≥ (Vin_max − Vsupply)/5 mA. This protection is mandatory per the datasheet's Input Overvoltage Protection section and applies identically to all four amplifiers in the AD8567ARUZ-REEL.
