CMP402GSZ

CMP402GSZ Description

The CMP402GSZ from Analog Devices Inc. is a general-purpose quad comparator housed in a 16-SOIC package, designed for precision signal comparison in a wide range of electronic systems. This surface-mount device operates on a ±5V dual supply and delivers robust performance with low input offset voltage (3mV max @ 5V) and minimal input bias current (3µA max @ 5V). Its CMOS/TTL-compatible outputs ensure seamless integration with both analog and digital circuits, while its 60dB CMRR and PSRR enhance noise immunity in electrically noisy environments. With a quiescent current as low as 1mA, it balances power efficiency with high-speed response (75ns max propagation delay), making it ideal for battery-sensitive and time-critical applications.

CMP402GSZ Features

• Quad Comparator Configuration: Four independent comparators in a single package, reducing board space and BOM complexity.
• Low Power Consumption: 1.2mA max quiescent current per channel, suitable for portable and energy-efficient designs.
• High Noise Immunity: 60dB CMRR and PSRR minimize errors from common-mode and supply variations.
• Wide Supply Range: Operates from ±5V, accommodating diverse system requirements.
• Fast Response Time: 75ns propagation delay ensures rapid decision-making in control loops.
• Robust Hysteresis (2mV): Prevents output oscillation near threshold points.
• Industry-Standard Compliance: ROHS3 and REACH unaffected, with MSL 1 (Unlimited) moisture sensitivity for reliable handling.

CMP402GSZ Applications

• Power Management Systems: Overvoltage/undervoltage detection in DC-DC converters and battery monitors.
• Industrial Control: Window comparators for threshold-based alarms or motor control feedback.
• Signal Conditioning: Zero-crossing detection, pulse-width modulation (PWM), and level shifting.
• Consumer Electronics: Touchscreen interfaces, audio processing, and sensor signal digitization.
• Automotive Electronics: Fault detection in CAN bus systems or load-dump protection circuits.

Conclusion of CMP402GSZ

The CMP402GSZ stands out as a versatile, high-performance quad comparator, combining low power, high speed, and exceptional noise rejection.
