TLV2702IDGK

Overview

The TLV2702IDGK is a dual-channel nano-power operational amplifier and push-pull 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 for the combined op-amp and comparator channels. The device features rail-to-rail input and output capabilities 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 maximum input offset voltage of 4 mV at 25°C, and reverse battery protection up to 18 V. It is housed in an 8-pin MSOP package.

Feature Summary

• Combines sub-micropower operational amplifier and push-pull comparator into a single package to reduce board space and part counts.
• Features reverse battery protection allowing operation under improper battery installation conditions without damage.
• Input common-mode range exceeds the positive supply rail by up to 5 V, enabling safe operation in harsh environments.
• Rail-to-rail input and output stages ensure compatibility with low-voltage microcontrollers and battery-powered systems.

Applications

• Portable battery monitoring systems
• Consumer medical electronics
• Security detection systems

Procurement Notes

Verify the specific ordering suffix 'DGK' corresponds to the 8-pin MSOP plastic package variant when sourcing components. Confirm that the industrial temperature grade (-40°C to 125°C) aligns with your environmental requirements. Ensure that the supply voltage constraints (2.5 V to 16 V) are strictly observed during system design to maintain specified performance levels.

Selection Notes

Select this component when simultaneous signal conditioning and threshold detection are required within strict power budgets. The ultra-low supply current makes it suitable for long-life portable applications. Consider the 5.5 kHz bandwidth limitation for high-speed signal processing tasks. Verify that the 8-pin MSOP package fits the available PCB real estate constraints compared to larger SOIC or DIP alternatives.

Part Context

This device belongs to the TLV270x family of nano-power amplifiers and comparators. The TLV2702 specifically integrates one operational amplifier and one comparator in a dual-channel configuration. It shares core specifications with the quad-channel TLV2704 but offers a more compact solution for applications requiring mixed analog signal processing and switching functions.
