The **ADCMP603BCPZ-R7** is a high-speed comparator manufactured by Analog Devices. It is designed for high-performance applications requiring fast signal processing and low power consumption. --- ### ## Technical Specifications Below are the primary electrical characteristics and physical parameters of the device: | Parameter | Specification | | :--- | :--- | | **Propagation Delay** | 3.5 ns (typical) | | **Supply Voltage** | 2.5 V to 5.5 V | | **Input Common-Mode Range** | -0.2 V to Vcc + 0.2 V | | **Output Logic** | LVDS (Low Voltage Differential Signaling) | | **Power Consumption** | ~8.5 mW per channel | | **Operating Temperature** | -40°C to +125°C | | **Package Type** | 12-lead LFCSP (Lead Frame Chip Scale Package) | --- ### ## Key Electronic Features 1. **LVDS Output Architecture:** The ADCMP603 uses LVDS output levels, which is crucial for high-speed data transmission. LVDS provides high noise immunity and reduces electromagnetic interference (EMI) due to its differential nature. 2. **Rail-to-Rail Inputs:** The input stage can handle voltages slightly beyond the supply rails. This prevents phase reversal and allows for flexible interfacing with various sensors and signal sources. 3. **Latch Functionality:** The device includes a **LE/HYS** pin. This pin serves two purposes: * **Latching:** It allows the user to "freeze" the output state based on a digital trigger. * **Hysteresis Control:** It allows the user to program a specific amount of hysteresis to prevent output oscillations caused by noisy input signals. 4. **High-Speed Performance:** With a propagation delay of only 3.5 ns, this part is ideal for clock recovery, high-speed pulse width modulation (PWM), and line receivers. --- ### ## Pin Configuration Summary | Pin No. | Name | Description | | :--- | :--- | :--- | | 1 | Vcc | Positive Supply Voltage | | 2, 3 | IN+, IN- | Differential Analog Inputs | | 6 | LE/HYS | Latch Enable and Hysteresis Control | | 8, 9 | Q, /Q | Differential LVDS Outputs | | 12 | Vee | Negative Supply (Ground) | --- ### ## Typical Application Circuits To implement this part, a standard decoupling capacitor (0.1 µF) is required near the supply pins. Because it uses LVDS outputs, a **100 $\Omega$ termination resistor** is typically placed across the differential output lines at the receiver end to match impedance. ```c // Pseudo-logic for Hysteresis calculation via LE/HYS pin V_hysteresis = (Voltage_on_LE_pin / Resistance_Value) * Constant; ```
