Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Number of Channels** | 4 (Quad) | | **Supply Voltage (Single)** | +4.5 V to +16 V | | **Supply Voltage (Dual)** | ±2.25 V to ±8.0 V | | **Output Current** | ±35 mA (High Drive) | | **Gain Bandwidth Product** | 5 MHz | | **Slew Rate** | 6 V/µs | | **Input/Output Type** | Rail-to-Rail Input and Output | | **Package Type** | LFCSP-16 (3x3 mm) | --- ### 2. Core Features * **Rail-to-Rail Performance:** The device allows both input and output signals to swing to the supply rails, maximizing dynamic range in low-voltage systems. * **High Output Drive:** Capable of driving large capacitive loads, making it ideal for LCD VCOM buffering or gamma correction. * **Low Power Consumption:** Operates at a low supply current of roughly 700 µA per amplifier. * **Thermal Efficiency:** The LFCSP (Lead Frame Chip Scale Package) provides excellent thermal dissipation despite its small footprint. --- ### 3. Pin Configuration (LFCSP-16) The AD8567ACPZ-R2 typically follows a standard quad-op-amp layout adapted for the 16-pin chip-scale package: 1. **Inputs (In+, In-):** Differential inputs for each of the four amplifiers. 2. **Outputs:** Dedicated output pins for Amp A, B, C, and D. 3. **Power Supply (V+, V-):** Single or dual supply connection. 4. **Exposed Pad:** Usually connected to V- for thermal grounding. --- ### 4. Typical Applications * **LCD Gamma Reference:** Providing stable voltages for display color accuracy. * **VCOM Buffers:** Acting as a low-impedance source for the common voltage plane in displays. * **Portable Instrumentation:** Due to its low power and small size. * **Signal Conditioning:** General-purpose filtering and amplification in 5V and 12V systems. --- ### 5. Part Number Breakdown * **AD8567:** The base model number for the Quad Rail-to-Rail Op-Amp. * **ACPZ:** Indicates the package type (LFCSP) and RoHS compliance (Lead-free). * **R2:** Specifies the tape and reel packaging size (typically 250 units for R2, compared to larger quantities for R7 or RL).
