The **MAX6037BAUK41+T** is a high-precision, low-power voltage reference integrated circuit (IC) manufactured by Analog Devices (formerly Maxim Integrated). It is specifically designed for applications requiring stability and low noise in a compact form factor. --- ### ## Technical Specifications The following table summarizes the key electrical characteristics of the MAX6037BAUK41+T: | Parameter | Specification | Details | | :--- | :--- | :--- | | **Output Voltage** | 4.096V | Fixed output | | **Initial Accuracy** | ±0.3% | Grade B accuracy | | **Temp. Coefficient** | 50 ppm/°C | Stability over temperature | | **Input Voltage Range** | 4.3V to 5.5V | Minimum $V_{IN}$ is $V_{OUT} + 200mV$ | | **Supply Current** | 200 µA (Max) | Low power consumption | | **Package Type** | SOT23-5 | Small Surface Mount Device (SMD) | | **Temperature Range** | -40°C to +125°C | Extended industrial range | --- ### ## Core Features 1. **Fixed Output (4.096V):** This specific voltage is ideal for 12-bit Analog-to-Digital Converters (ADCs) because $4096 \text{ mV} / 2^{12} \text{ bits} = 1 \text{ mV}$ per Least Significant Bit (LSB), simplifying digital calculations. 2. **Shutdown Mode:** The device features a shutdown pin that reduces the current draw to less than 1 µA, making it suitable for battery-powered devices. 3. **Low Dropout Voltage:** It requires very little "headroom" between the input and output voltage (typically 200mV), allowing it to work with 5V rails effectively. 4. **Stable with Capacitive Loads:** It is designed to remain stable even when large decoupling capacitors (up to 1µF) are placed on the output. --- ### ## Pin Configuration (SOT23-5) | Pin Number | Name | Function | | :--- | :--- | :--- | | 1 | **SHDN** | Shutdown Control (Active Low) | | 2 | **GND** | Ground | | 3 | **IN** | Supply Voltage Input | | 4 | **OUT** | Reference Voltage Output | | 5 | **ADJ/NC** | No Connection (for fixed versions) | --- ### ## Common Applications * **Precision ADCs/DACs:** Used as a steady reference for data converters. * **Portable Equipment:** Due to the low power and shutdown feature. * **Industrial Process Control:** Reliable operation in harsh temperature environments. * **Medical Instrumentation:** High precision for sensor calibration.
