TLV3402IDG4

Comparators Overview

The TLV3402IDG4 is a dual nanopower analog comparator manufactured by Texas Instruments. It features an open-drain output configuration and operates within a supply voltage range of 2.7 V to 16 V. The device draws a typical operating supply current of 640 nA per channel. Key electrical specifications include a maximum input offset voltage of 3.6 mV, an input bias current of 250 pA, and a response time of 80 µs. It supports rail-to-rail inputs and provides a common-mode rejection ratio of 50 dB and a power-supply rejection ratio of 70 dB. The component is available in an 8-pin VSSOP package and functions reliably across an extended temperature range from -40°C to +125°C.

Comparators Procurement Notes

Verify the specific suffix 'DG4' against the manufacturer's official documentation to confirm pinout compatibility and RoHS status. Ensure the ordering part number matches the exact package type required for your PCB layout. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement decisions.

Comparators Selection Notes

Select this component when designing systems that demand ultra-low power consumption alongside precise voltage threshold detection. The wide supply voltage range accommodates single-supply operations without level shifting. Consider the open-drain output requirement for pull-up resistor implementation in the circuit design phase.

Comparators Part Context

This device belongs to the TLV34xx series of nanopower comparators from Texas Instruments. It shares architectural similarities with other members like the TLV3401 and TLV3404 but differs in channel count and package options. The series is designed specifically for applications where power conservation is critical while maintaining adequate speed and accuracy.

Comparators Replacement Considerations

Direct substitutes may include the TLV3402IP or TLV3402IDGKG4. Verify package dimensions and pin assignments carefully as PDIP and VSSOP variants differ physically. Ensure functional equivalence regarding input offset voltage and supply current limits before swapping components.
