The **TLV2711CDBVRG4** is a high-performance, low-power operational amplifier (Op-Amp) manufactured by Texas Instruments. It is part of the LinCMOS™ family, specifically designed for portable and battery-powered applications. --- ## 1. Technical Specifications Below are the primary electrical characteristics and physical parameters of the device: | Parameter | Specification | | :--- | :--- | | **Device Type** | Operational Amplifier (Op-Amp) | | **Number of Channels** | 1 (Single) | | **Supply Voltage (Single)** | 2.7V to 10V | | **Supply Voltage (Dual)** | ±1.35V to ±5V | | **Supply Current** | 3.4 µA (Ultra-low power) | | **Gain Bandwidth Product** | 65 kHz | | **Slew Rate** | 0.025 V/µs | | **Package / Case** | SOT-23-5 | | **Output Type** | Rail-to-Rail | --- ## 2. Key Features and Benefits ### A. Ultra-Low Power Consumption With a typical supply current of only **3.4 µA**, this part is ideal for "always-on" monitoring circuits where power conservation is critical to battery life. ### B. Rail-to-Rail Output The output swing can reach very close to the supply rails. This maximizes the dynamic range, which is essential when working with low-voltage supplies (like a single 3V coin cell). ### C. Input Characteristics * **High Input Impedance:** Because it uses CMOS technology, the input bias currents are extremely low (pico-ampere range), preventing loading on sensitive sensor inputs. * **Common-Mode Input:** The input range includes the negative rail (ground in single-supply mode). --- ## 3. Pin Configuration (SOT-23-5) The TLV2711CDBVRG4 uses a standard 5-pin SOT-23 layout: 1. **IN+**: Non-inverting input 2. **VSS / GND**: Negative power supply or ground 3. **IN-**: Inverting input 4. **OUT**: Amplifier output 5. **VDD**: Positive power supply --- ## 4. Part Number Breakdown Understanding the suffix helps in identifying packaging and environmental standards: * **TLV2711**: Device family (Low power CMOS Op-Amp). * **C**: Commercial temperature range (0°C to 70°C). * **DBV**: SOT-23 package type. * **R**: Tape and Reel (packaging method). * **G4**: Green/Lead-free (RoHS compliant). --- ## 5. Typical Applications * **Battery-Powered Medical Tools:** Heart rate monitors or glucose meters. * **Remote Sensors:** Environmental sensors that operate for years on a single battery. * **Microphone Preamplifiers:** For low-frequency, low-power audio capture. * **Active Filters:** Low-speed signal conditioning. ---
