TLV3402IDRG4

Comparators Overview

The TLV3402IDRG4 is a dual nanopower comparator manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. It features open-drain CMOS outputs and operates within a supply voltage range of 2.7V to 16V (single) or ±1.35V to ±8V (dual). Key electrical specifications include a maximum input offset voltage of 3.6mV at 15V, a maximum input bias current of 250pA at 15V, and a typical quiescent current of 950nA per channel. The device supports a propagation delay of up to 300µs and offers high common-mode rejection ratio (CMRR) of 88dB and power supply rejection ratio (PSRR) of 105dB.

Comparators Feature Summary

• Nanopower consumption with low quiescent current for battery-operated applications
• Open-drain output configuration compatible with various logic families
• High precision performance with low input offset voltage and bias current

Comparators Applications

• Battery-powered sensing systems requiring ultra-low power operation
• Threshold detection circuits in portable electronic devices
• Signal conditioning stages in low-voltage analog front ends

Comparators Procurement Notes

Verify the specific ordering suffix IDRG4 confirms the tape-and-reel packaging format and RoHS compliance status. Ensure the component matches the 8-SOIC physical dimensions and pinout requirements for your PCB layout. Confirm that the manufacturer's datasheet revision aligns with your design specifications regarding electrical characteristics and thermal performance.

Comparators Selection Notes

Select this component when designing low-voltage systems where minimizing static power consumption is critical. The open-drain output requires external pull-up resistors, which must be sized according to the desired switching speed and load capacitance. Consider the input offset voltage tolerance if precise threshold detection is required without calibration.

Comparators Part Context

This part belongs to the TLV340x family of comparators, designed specifically for applications demanding minimal power usage while maintaining adequate signal integrity. It serves as a low-cost alternative to higher-power operational amplifiers used in comparator configurations, offering dedicated optimization for threshold detection tasks in consumer and industrial electronics.

Comparators Replacement Considerations

Direct substitutes may include other dual comparators from Texas Instruments such as the TLV3402IDR (tray version) or similar nanopower series parts. Verify pin compatibility and electrical parameter equivalence before substitution.
