TLV2304IPWR

Overview

The TLV2304IPWR 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 split supply operation supported between ±1.25 V and ±8 V. The device draws a typical supply current of 1.4 μA per channel (one op-amp and one comparator). Key electrical characteristics include a gain bandwidth product of 5.5 kHz, an input offset voltage of up to 4000 μV at 25°C, and a common-mode rejection ratio of 90 dB at 15 V. The package is TSSOP-14.

Feature Summary

• Combines four operational amplifiers and four open-drain comparators in a single package for board space reduction.
• Features rail-to-rail input and output capability for the operational amplifiers.
• Includes reverse battery protection allowing inputs to withstand voltages up to 18 V.
• Supports extended common-mode input range exceeding the positive supply rail by 5 V.

Applications

• Battery-powered portable applications requiring low quiescent current
• Micropower microcontroller interfacing systems
• Signal conditioning circuits utilizing mega-ohm resistors

Procurement Notes

Verify the specific ordering suffix 'R' confirms the tape-and-reel packaging format as indicated in the datasheet options. Confirm the industrial temperature grade (-40°C to 125°C) matches system requirements. Ensure the TSSOP-14 package dimensions align with PCB layout constraints. Cross-reference the manufacturer part number TLV2304IDR or similar reel variants if exact suffix matching is required for inventory systems.

Selection Notes

Select this component when both amplification and comparison functions are needed within a single footprint. The low supply current makes it suitable for energy-constrained designs. Consider the open-drain comparator output requirement for pull-up resistor implementation. Verify that the 5.5 kHz bandwidth meets signal frequency needs. Check compatibility with Li-Ion battery systems operating near 2.5 V.

Part Context

The TLV2304 belongs to the TLV230x family of nano-power operational amplifiers and open-drain comparators. This series integrates sub-micropower performance with high input impedance. The quad configuration provides two operational amplifiers and two comparators per device, distinct from the dual-channel TLV2302 variant. The family emphasizes low power consumption while maintaining DC accuracy through low offset voltage specifications.

Replacement Considerations

TLV2304ID: Same functional device but in SOIC-8 package instead of TSSOP-14. TLV2304IN: Same functional device but in PDIP-14 package instead of TSSOP-14. Verify pinout compatibility and thermal dissipation ratings when substituting packages.
