TLV2302IDGK

Overview

The TLV2302IDGK is a dual-channel mixed-signal integrated circuit combining a nano-power operational amplifier and an open-drain comparator within a single VSSOP-8 package. It operates on a supply voltage range of 2.5 V to 16 V with a typical quiescent current of 1.4 μA. The device features rail-to-rail input/output for the amplifier, reverse battery protection up to 18 V, and an extended common-mode input range extending 5 V above the positive supply rail.

Feature Summary

• Combines a low-power operational amplifier and an open-drain comparator in one package
• Features reverse battery protection capable of withstanding voltages up to 18 V
• Supports input common-mode voltage ranges exceeding the supply rails by 5 V
• Provides rail-to-rail input and output capabilities for the operational amplifier section

Applications

• Battery-powered portable systems requiring minimal quiescent current
• Signal conditioning circuits utilizing high-value mega-ohm resistors
• Microcontroller interfacing compatible with low-voltage logic levels
• Harsh environments requiring tolerance to overvoltage conditions at inputs

Procurement Notes

Verify the specific suffix 'DGK' corresponds to the VSSOP-8 plastic package and industrial temperature grade (-40°C to 125°C). Confirm that the ordering part number matches the required tape-and-reel or tube packaging option, as indicated by potential 'R' suffixes in manufacturer documentation. Ensure compatibility with the specified 2.5 V to 16 V supply range for your target application.

Selection Notes

Select this component when board space is limited and both amplification and threshold detection are required. It is suitable for applications demanding ultra-low power consumption, such as those powered by Li-Ion batteries. Consider the open-drain nature of the comparator output, which requires an external pull-up resistor, versus the push-pull output of the operational amplifier.

Part Context

This device belongs to the TLV230x family of nanopower operational amplifiers and open drain comparators. The family includes variants like the TLV2304, which offers four channels in a TSSOP package. These devices utilize CMOS technology to achieve micro-power operation while maintaining DC accuracy through low offset voltage and high common-mode rejection ratios across the industrial temperature range.
