### ADCMP600BKSZ-R2 Technical Overview The **ADCMP600BKSZ-R2** is a high-speed comparator manufactured by Analog Devices. It is designed for high-performance applications requiring fast response times and low power consumption. --- ### Key Specifications | Feature | Description | | :--- | :--- | | **Propagation Delay** | 3.5 ns (Typical) | | **Supply Voltage Range** | 2.5 V to 5.5 V | | **Output Type** | LVDS/CMOS Compatible | | **Input Common-Mode Range** | −0.2 V to VCC + 0.2 V | | **Package Type** | SC70-5 (BKSZ suffix) | | **Quiescent Current** | 3 mA | --- ### Core Functional Parts #### 1. Input Stage The input stage features **rail-to-rail** capability. This means it can handle input voltages that slightly exceed the power supply rails (up to 200 mV beyond the rails). This prevents "phase reversal," a common issue in older comparators where the output would flip incorrectly when the input range was exceeded. #### 2. High-Speed Core The internal circuitry utilizes a high-speed bipolar process to achieve a propagation delay of just **3.5 ns**. This makes it suitable for: * Clock recovery circuits. * High-speed window comparators. * Line receivers. #### 3. Output Driver The output is optimized for driving digital logic. While it is rail-to-rail, it is specifically designed to interface cleanly with **TTL and CMOS** logic families. The "R2" in the part number typically refers to the tape and reel quantity (usually a 7-inch reel with 250 units). #### 4. Package: SC70-5 The "BKSZ" designation indicates the **SC70** package, which is an ultra-miniature surface-mount package. This is critical for space-constrained PCB designs like mobile devices or dense industrial sensor modules. --- ### Typical Application Circuit The ADCMP600 is often used in a basic threshold detection configuration. ```c // Simplified Logic Representation If (V_input_plus > V_input_minus) { Output = VCC; // Logic High } else { Output = GND; // Logic Low } ``` --- ### Pin Configuration (SC70-5) 1. **Vout:** Comparator Output 2. **Vee/GND:** Negative Supply or Ground 3. **Vin+:** Non-inverting Input 4. **Vin-:** Inverting Input 5. **Vcc:** Positive Supply Voltage
