TLV2304IDR

Overview

The TLV2304IDR is a quad 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 per channel (one op-amp and one comparator). The device features rail-to-rail input/output for the amplifiers and reverse battery protection up to 18 V. Key electrical specifications include a gain bandwidth product of 5.5 kHz, an input offset voltage of 390 μV typical at 25°C, and operation across an industrial temperature range of –40°C to 125°C. It is housed in a 14-pin SOIC package.

Feature Summary

• Combines two operational amplifiers and two comparators in a single package to reduce board space and part counts.
• Features ultra-low supply current consumption of 1.4 μA, making it suitable for battery-powered portable applications.
• Provides reverse battery protection up to 18 V to guard against over-current conditions from improper installation.
• Supports input voltages up to 5 V above the positive supply rail without damage.

Applications

• Battery-powered portable systems requiring low quiescent current
• Micropower microcontroller interfacing
• Signal conditioning circuits with mega-ohm resistors
• Harsh environments requiring reverse battery protection

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix 'IDR' corresponds to the 14-SOIC tape-and-reel packaging variant. Check for end-of-life status updates as availability may be restricted. Ensure compliance with RoHS3 standards and verify the operating temperature range matches application requirements before finalizing procurement.

Selection Notes

Select this component when both amplification and comparison functions are required in a single footprint. It is ideal for designs prioritizing minimal power consumption and extended battery life. Consider the 5.5 kHz bandwidth limit for signal processing speed requirements. Verify that the open-drain comparator output configuration aligns with the system's pull-up resistor strategy.

Part Context

The TLV2304IDR belongs to the TLV230x family of nano-power operational amplifiers and open-drain comparators. This series integrates sub-micropower signal conditioning capabilities into a unified package. The family includes dual variants like the TLV2302 and quad variants like the TLV2304, offering designers flexibility in channel count while maintaining consistent low-power performance characteristics.
