TLV3404CPW

Comparators Overview

The TLV3404CPW is a quad nanopower open-drain output comparator manufactured by Texas Instruments. It features four independent comparators in a 14-TSSOP package. The device operates with a supply voltage range of 2.5 V to 16 V for single supply or ±1.25 V to ±8 V for dual supply. Key electrical specifications include a maximum input offset voltage of 3.6 mV at 15 V, a maximum input bias current of 250 pA at 15 V, and a typical quiescent current of 950 nA per channel. The propagation delay is typically 300 µs, with CMRR and PSRR values of 88 dB and 105 dB respectively.

Comparators Feature Summary

• Quad configuration providing four independent comparators in a compact surface-mount package
• Ultra-low power consumption with nanopower operation suitable for battery-powered applications
• Open-drain output architecture allowing flexible logic level interfacing
• High precision performance with low input offset voltage and bias current

Comparators Applications

• Battery-powered monitoring systems requiring minimal quiescent current
• Threshold detection circuits in portable electronic devices
• General-purpose voltage comparison in low-power analog signal processing
• Window comparator configurations for voltage supervision

Comparators Procurement Notes

Verify the specific suffix 'CPW' against the manufacturer's official datasheet to confirm the commercial temperature grade (0°C to 70°C) and tube packaging format. Ensure compatibility with the required supply voltage range and output drive capabilities for the target application. Cross-reference the ordering part number with the latest TI documentation to avoid discrepancies due to product transitions or packaging changes.

Comparators Selection Notes

Select this component when multiple independent comparators are needed in a space-constrained design with strict power limitations. The open-drain output requires external pull-up resistors, which must be accounted for in the circuit design. Consider the propagation delay and offset voltage specifications to ensure they meet the timing and accuracy requirements of the specific application compared to faster or higher-precision alternatives.

Comparators Part Context

The TLV3404 belongs to the TLV340x family of nanopower comparators from Texas Instruments, designed for high-efficiency analog signal conditioning. This family includes variants with one, two, and four channels, sharing similar electrical characteristics such as low input bias current and wide supply voltage ranges. The CPW variant specifically denotes the commercial temperature range and TSSOP-14 package, distinguishing it from industrial grade or other package options within the same functional series.

Comparators Replacement Considerations

Direct replacements include other TLV3404 variants with different temperature grades or packages, such as TLV3404IPW for industrial temperature range. Functional equivalents from other manufacturers should be evaluated based on pin compatibility, supply voltage range, and electrical parameters like offset voltage and quiescent current.
