The **LL204L-D14-R** is a specific part number typically associated with an **Operational Amplifier (Op-Amp)** or a **Voltage Regulator**, manufactured by UTC (Unisonic Technologies Co., Ltd). Based on standard industry nomenclature for this series, it refers to a **Dual Low Power Operational Amplifier**. Below is the detailed breakdown of its specifications and part numbering logic. ### 1. General Specifications The device is designed for high-performance applications requiring low power consumption and wide supply voltage ranges. | Parameter | Specification | | :--- | :--- | | **Component Type** | Dual Operational Amplifier | | **Package Type** | SOP-14 (Small Outline Package) | | **Operating Voltage** | 3V to 32V (Single), ±1.5V to ±16V (Dual) | | **Input Bias Current** | 45 nA (Typical) | | **Output Current** | 20 mA to 40 mA | | **Short Circuit Protection** | Yes | | **Operating Temperature** | -40°C to +85°C | --- ### 2. Part Number Breakdown The suffix and prefix provide specific information about the packaging and lead-free status. | Code Segment | Meaning | | :--- | :--- | | **LL204** | Base Part Number (Series) | | **L** | Halogen-Free and Lead-Free (Green) | | **D14** | Package Code: **SOP-14** (Surface Mount, 14 Pins) | | **R** | Packing Type: **Tape & Reel** | --- ### 3. Pin Configuration (Typical SOP-14) Since this is a "Dual" or sometimes "Quad" configuration depending on the specific internal logic of the 204 series, the SOP-14 layout usually follows this standard: * **Vcc+ / Vcc-**: Power Supply pins. * **Inverting Input (-)**: Signal input with phase reversal. * **Non-Inverting Input (+)**: Signal input maintaining phase. * **Output**: Amplified signal output. --- ### 4. Key Features * **Wide Bandwidth:** Suitable for signal processing and filtering. * **Low Input Offset:** Minimizes errors in precision circuits. * **Internal Frequency Compensation:** Simplifies circuit design as external capacitors are not required for stability. * **Battery Friendly:** Very low current drain, making it ideal for portable electronics. --- ### 5. Common Applications 1. **Transducer Amplifiers:** For boosting small signals from sensors. 2. **DC Gain Blocks:** Used in control systems. 3. **Active Filters:** Low-pass, high-pass, and band-pass filters. 4. **Analog Calculators:** Summing or differentiating circuits.
