TLC393ID

TLC393ID Description

The TLC393ID from Texas Instruments is a dual general-purpose comparator from the LinCMOS™ series, designed for precision applications requiring low power consumption and high performance. Housed in an 8-SOIC package, this surface-mount device operates over a 3V to 16V supply range, making it versatile for both single and dual-voltage systems. With a quiescent current of just 65µA (max) and an ultra-low input bias current of 5pA (max), it excels in battery-powered and energy-sensitive designs. The comparator offers a fast propagation delay of 4.5µs (max) and a high 84dB CMRR, ensuring reliable signal integrity in noisy environments.

TLC393ID Features

• Low Power Consumption: Ideal for portable and IoT applications with a max quiescent current of 65µA.
• High Precision: 5mV (max) input offset voltage at 10V ensures accurate comparisons.
• Robust Performance: 84dB CMRR minimizes common-mode interference.
• Wide Supply Range: Operates from 3V to 16V, supporting diverse system requirements.
• Low Input Bias Current: 5pA (max) reduces errors in high-impedance circuits.
• Dual Comparator Design: Two independent comparators in a compact 8-SOIC package.
• Reliability: ROHS3 Compliant and REACH Unaffected, meeting environmental standards.

TLC393ID Applications

• Battery-Powered Systems: Due to its ultra-low power draw, it’s perfect for wearables, sensors, and energy harvesters.
• Signal Conditioning: High CMRR makes it suitable for analog-to-digital interfaces and noise filtering.
• Threshold Detection: Used in overvoltage/undervoltage protection circuits and window comparators.
• Industrial Control: Reliable performance in motor control, PLCs, and instrumentation.
• Consumer Electronics: Ideal for touchscreens, power management, and audio processing.

Conclusion of TLC393ID

The TLC393ID stands out as a high-performance, low-power dual comparator, combining precision, speed, and versatility. Its wide supply range, low input bias, and high CMRR make it superior to many general-purpose comparators, particularly in battery-operated and noise-sensitive applications. While marked as Last Time Buy, its ROHS3 compliance and industrial-grade reliability ensure it remains a viable choice for legacy and new designs requiring dependable signal comparison.
