The **ADCMP370AKS-R7** is a low-power, general-purpose comparator manufactured by Analog Devices. It is designed specifically for power-sensitive applications where a small footprint and low current consumption are critical. --- ### ## Technical Specifications Overview The following table highlights the primary electrical characteristics of the ADCMP370AKS-R7: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Analog Devices | | **Supply Voltage Range** | 2.25V to 5.5V | | **Supply Current (Typical)** | 5 μA | | **Propagation Delay** | 5 μs (typical) | | **Output Type** | Open-Drain | | **Package Type** | SC70-5 (5-lead) | | **Input Offset Voltage** | 9 mV (max) | | **Operating Temperature** | -40°C to +85°C | --- ### ### Key Features and Components 1. **Open-Drain Output**: The device features an open-drain output stage. This is beneficial for "wired-AND" logic or for interfacing with different logic levels (e.g., using a pull-up resistor to connect a 3.3V comparator output to a 5V microcontroller input). 2. **Ultra-Low Power Consumption**: With a typical current draw of only **5 μA**, it is ideal for battery-powered devices where energy efficiency is the highest priority. 3. **Input Range**: The input common-mode range includes the negative supply (Ground), making it suitable for single-supply operations. 4. **Small Form Factor**: The **SC70-5** package is extremely small, allowing for high-density PCB layouts in portable electronics like smartphones or IoT sensors. --- ### ### Common Applications * **Battery Monitoring**: Triggering an alert when a battery falls below a certain voltage threshold. * **Threshold Detectors**: Used in sensors to determine if a signal has crossed a specific level. * **Level Translators**: Leveraging the open-drain output to bridge different voltage domains. * **Window Comparators**: Using two units to detect if a signal stays within a specific voltage range. --- ### ### Basic Connection Diagram To use the ADCMP370, you typically need a pull-up resistor on the output pin because of its open-drain architecture. ```cpp // Logic Representation VCC (2.25V - 5.5V) | [Pull-up Resistor] | +------- Output (Pin 4) | ADCMP370 Pin 1: Non-Inverting Input (+) Pin 2: Ground (VSS) Pin 3: Inverting Input (-) Pin 5: Supply Voltage (VDD) ```
