CMP04FS

CMP04FS Description

The CMP04FS from Analog Devices Inc. is a general-purpose quad comparator designed for precision signal conditioning and monitoring applications. Housed in a 14-SOIC package, this surface-mount IC delivers robust performance with a wide supply voltage range of 3.3V to 36V (single) or ±1.65V to ±18V (dual), making it versatile for both low and high-voltage systems. Despite its obsolete status, the CMP04FS remains a reliable choice for legacy designs, offering low input offset voltage (1mV max @ 5V) and minimal input bias current (0.1µA max @ 5V). Its 100dB CMRR and PSRR ensure exceptional noise immunity, critical for industrial and automotive environments.

CMP04FS Features

• High Precision: Low offset voltage (1mV max) and bias current (0.1µA max) enhance accuracy in sensitive circuits.
• Excellent Noise Rejection: 100dB CMRR and PSRR minimize interference in noisy environments.
• Wide Supply Range: Supports single (3.3V–36V) or dual (±1.65V–±18V) supplies for flexible integration.
• Low Power Consumption: Quiescent current of 3mA (max) balances performance and efficiency.
• Quad Comparator Design: Four independent comparators in one package reduce board space and BOM complexity.
• Robust Packaging: 14-SOIC tube packaging ensures mechanical durability and ease of handling.

CMP04FS Applications

The CMP04FS excels in systems requiring high-precision voltage monitoring or threshold detection, such as:

• Power Management: Overvoltage/undervoltage protection in DC-DC converters or battery chargers.
• Industrial Control: Window comparators for fault detection in PLCs or motor drives.
• Automotive Systems: Signal conditioning in sensors or load-dump protection circuits.
• Test & Measurement: Precision level shifting or waveform shaping in instrumentation.

Conclusion of CMP04FS

While obsolete, the CMP04FS remains a high-performance quad comparator for legacy or long-lifecycle designs. Its low noise, wide voltage range, and precision make it ideal for demanding industrial, automotive, and power applications. Engineers seeking a reliable, space-saving solution for multi-channel comparison tasks will find the CMP04FS a compelling option, despite newer alternatives.
