TLV2302IDGKR

Overview

The TLV2302IDGKR is a dual-channel nano-power operational amplifier and open-drain comparator integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 16 V, consuming only 1.4 μA of quiescent current. The device features rail-to-rail input and output capabilities for the amplifier section, with an input common-mode range extending from -0.1 V to VCC + 5 V. Key electrical parameters include a gain bandwidth product of 5.5 kHz, a typical input offset voltage of 390 μV, and reverse battery protection up to 18 V.

Feature Summary

• Combines a sub-micropower operational amplifier and an open-drain comparator in a single package to reduce board space and part counts.
• Features rail-to-rail input and output for the amplifier section, allowing full signal swing capability.
• Includes reverse battery protection up to 18 V to guard against over-current conditions during improper installation.
• Supports extended input voltage ranges exceeding the positive supply rail by 5 V without damage.

Applications

• Battery-powered portable applications requiring low quiescent current
• Systems utilizing Li-Ion batteries or micropower microcontrollers
• Signal conditioning circuits in harsh environments

Procurement Notes

Verify the specific ordering suffix 'R' confirms the reel packaging format as distinct from tube packaging. Ensure the component matches the industrial temperature grade specifications (-40°C to 125°C) required for your application environment. Cross-reference the datasheet revision date to confirm parameter consistency before finalizing procurement.

Selection Notes

Select this component when both amplification and comparison functions are needed within strict power constraints. The wide common-mode input range allows operation above the supply rail, suitable for high-side sensing. Verify that the open-drain comparator output configuration aligns with your logic level requirements and pull-up resistor needs.

Part Context

This device belongs to the TLV230x family of nano-power operational amplifiers and comparators. It is designed to offer excellent micropower signal conditioning while minimizing active area on the printed-circuit board. The family includes variants such as the TLV2304, which provides two amplifiers and two comparators in a larger package.

FAQ

What is the maximum input voltage relative to the supply rail?

The inputs can be taken up to 5 V above the positive supply rail (VCC + 5 V) without causing damage to the device.

How does the device handle reverse battery connections?

The device provides reverse battery protection up to 18 V, limiting the reverse supply current to typically less than 100 nA at 25°C.
