TLV3402ID

TLV3402ID Description

The TLV3402ID from Texas Instruments is a dual-channel general-purpose comparator designed for precision applications requiring ultra-low power consumption and high performance. Packaged in an 8-SOIC tube, this IC operates over a wide supply voltage range of 2.7V to 16V (single) or ±1.35V to ±8V (dual), making it versatile for both single and split-rail designs. With a quiescent current as low as 950nA (max), it is optimized for battery-powered and energy-efficient systems. The device features low input offset voltage (3.6mV max @ 15V) and minimal input bias current (250pA max @ 15V), ensuring high accuracy in signal detection.

TLV3402ID Features

• Ultra-Low Power: 950nA max quiescent current extends battery life in portable applications.
• High CMRR & PSRR: 88dB CMRR and 105dB PSRR minimize noise and supply variations.
• Wide Voltage Range: Supports 2.7V–16V (single) or ±1.35V–±8V (dual) for flexible power configurations.
• Low Input Errors: 3.6mV max offset voltage and 250pA max bias current enhance precision.
• Fast Response: 300µs max propagation delay balances speed with power efficiency.
• Robust Output: 10mA output current drives LEDs, relays, or logic gates directly.
• Reliable Compliance: ROHS3 and REACH unaffected, with MSL 1 (unlimited) moisture sensitivity.

TLV3402ID Applications

• Battery-Powered Systems: Ideal for wearables, IoT sensors, and energy harvesters due to ultra-low current draw.
• Threshold Detection: Precision window comparators, overvoltage/undervoltage monitors.
• Industrial Controls: Motor drive protection, level shifting, and signal conditioning in harsh environments.
• Portable Medical Devices: Low-power ECG, glucose monitors where accuracy and efficiency are critical.
• Automotive Electronics: Load dump protection, battery management with wide supply tolerance.

Conclusion of TLV3402ID

The TLV3402ID stands out for its ultra-low power consumption, high noise immunity, and wide operating range, making it a top choice for precision, battery-sensitive designs. While marked as Last Time Buy, its ROHS3 compliance and industrial-grade reliability ensure suitability for legacy and new projects. Engineers should consider this comparator for cost-sensitive, low-power applications where TI’s proven performance is required.
