TLV2702IDG4

Overview

The TLV2702IDG4 is a dual-channel nano-power operational amplifier and push-pull comparator integrated in an 8-pin MSOP package. It operates on a single supply voltage ranging from 2.5 V to 16 V, with split supply operation supported between ±1.25 V and ±8 V. The device consumes only 1.4 µA of supply current while providing a gain bandwidth product of 5.5 kHz and a slew rate of 2.5 V/ms. Input common-mode range extends from –0.1 V to VCC + 5 V, ensuring compatibility with rail-to-rail signal processing. Reverse battery protection allows the inputs to withstand up to 18 V without damage.

Feature Summary

• Combines sub-micropower operational amplifier and push-pull comparator into a single package for reduced board space and part counts.
• Features reverse battery protection up to 18 V and input common-mode range exceeding the positive supply rail by 5 V.
• Provides rail-to-rail input and output capabilities with extremely low input bias currents suitable for high-impedance sources.
• Operates reliably across the industrial temperature range from –40°C to 125°C.

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 package configuration required for your PCB layout. Confirm that the 'I' suffix meets the necessary industrial temperature specifications for your operating environment. Ensure the component matches the exact Texas Instruments datasheet revision referenced in your design documentation to guarantee parameter consistency.

Selection Notes

Select this component when both amplification and comparison functions are needed within a single footprint to minimize assembly costs. It is ideal for applications requiring ultra-low quiescent current to extend battery life in portable devices. Consider its extended common-mode input range if signals exceed the positive supply rail or go slightly below ground potential.

Part Context

This device belongs to the TLV270x family of nano-power operational amplifiers and comparators manufactured by Texas Instruments. The family includes variants such as the TLV2704 quad configuration. These components are designed specifically for battery-powered applications where power conservation and compact packaging are critical design constraints.

FAQ

How does the TLV2702 handle reverse battery connections?

The device features reverse battery protection up to 18 V. In this condition, the supply current remains typically less than 100 nA at 25°C, determined by the leakage of internal Schottky diodes.

What is the maximum input voltage the device can tolerate?

The input voltage range extends from –0.1 V to VCC + 5 V. This allows inputs to be taken 5 V above the positive supply rail without damaging the device.
