TLV2304ID

Overview

The TLV2304ID is a quad nano-power operational amplifier and open-drain comparator integrated circuit manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.5 V to 16 V with a typical quiescent current of 1.4 μA per channel (one op-amp and one comparator). The device features rail-to-rail input and output capabilities for the amplifiers, an extended common-mode input range up to VCC + 5 V, and reverse battery protection up to 18 V. It is housed in a 14-pin SOIC package and specified for industrial temperatures from -40°C to 125°C.

Feature Summary

• Combines two operational amplifiers and two open-drain comparators in a single package to reduce board space and part counts.
• Features ultra-low supply current of 1.4 μA, making it suitable for battery-powered portable applications.
• Includes reverse battery protection up to 18 V to guard against improper installation.
• Operates with inputs exceeding the positive supply rail by up to 5 V without damage.

Applications

• Battery-powered portable systems requiring low quiescent current
• Micropower microcontroller interfacing
• Signal conditioning circuits with high impedance sources

Procurement Notes

Verify the specific ordering suffix 'ID' corresponds to the 14-pin SOIC package and industrial temperature grade (-40°C to 125°C) as defined in the datasheet. Confirm that the open-drain comparator outputs require external pull-up resistors for proper logic level translation in the target application design.

Selection Notes

Select this component when both signal amplification and threshold detection are required within a single IC footprint. It is appropriate for designs prioritizing minimal power consumption over high-speed performance, given its 5.5 kHz gain-bandwidth product. Ensure the load can accommodate the open-drain nature of the comparator outputs.

Part Context

The TLV2304ID belongs to the TLV230x family of nano-power operational amplifiers and comparators. This family includes dual-channel variants like the TLV2302 and other members such as the TLV270x series which feature push-pull comparator outputs instead of open-drain.

Replacement Considerations

TLV2304IDG4 is a documented equivalent variant within the same family offering identical electrical specifications and functionality.

FAQ

What is the maximum voltage the inputs can withstand above the positive supply rail?

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

How does the TLV2304ID 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.
