The **ADR365BUJZ-R2** is a high-precision, low-power, low-dropout voltage reference manufactured by **Analog Devices**. It is part of the ADR36x family, known for its small form factor and high stability. --- ## 1. Key Technical Specifications The following table summarizes the primary electrical characteristics of the ADR365BUJZ-R2: | Parameter | Specification | | :--- | :--- | | **Output Voltage ($V_{out}$)** | 5.0 V | | **Initial Accuracy** | ±0.1% (5 mV) | | **Temperature Coefficient** | 9 ppm/°C (Maximum) | | **Input Voltage Range** | 5.3 V to 15 V | | **Quiescent Current** | 190 μA (Maximum) | | **Output Current Capability** | 5 mA (Source) / 2 mA (Sink) | | **Operating Temperature** | -40°C to +125°C | | **Package Type** | TSOT-23-5 (Thin SOT) | --- ## 2. Core Features & Architecture The ADR365 series is designed using a proprietary **band gap reference** architecture that achieves high performance with very low power consumption. * **Low Dropout (LDO):** It requires only a small voltage overhead (300mV) above the output voltage to maintain regulation. * **Low Noise:** It provides clean voltage output, essential for high-resolution Data Converters (ADCs/DACs). * **Shutdown Mode:** This specific variant (in the 5-lead TSOT package) typically includes a shutdown pin to reduce current consumption to less than 1 μA when the device is not in use. * **High Stability:** It offers excellent long-term drift and load/line regulation characteristics. --- ## 3. Pin Configuration (TSOT-23-5) The device is housed in a 5-pin package with the following typical pinout: | Pin Number | Name | Function | | :--- | :--- | :--- | | 1 | **$V_{in}$** | Input Voltage Supply | | 2 | **GND** | Ground | | 3 | **SHDN** | Shutdown (Active Low) | | 4 | **NC** | No Connect (Keep floating) | | 5 | **$V_{out}$** | Reference Voltage Output | --- ## 4. Typical Applications Due to its precision and small footprint, the ADR365BUJZ-R2 is commonly found in: 1. **Precision Data Acquisition:** Providing the reference voltage for 12-bit to 16-bit ADCs. 2. **Portable Instrumentation:** Battery-powered devices that require high accuracy and low power draw. 3. **Industrial Process Control:** Reliable voltage standards for sensors and PLC modules. 4. **Medical Equipment:** High-stability requirements for monitoring and diagnostic tools. --- ## 5. Part Number Decoding The suffix **"BUJZ-R2"** provides specific manufacturing info: * **B**: Denotes the higher grade (better accuracy/tempco than 'A' grade). * **UJZ**: Refers to the TSOT-23-5 package. * **R2**: Indicates the tape and reel size (7-inch reel containing 250 units).
