TLV2302ID

Overview

The TLV2302ID is a dual-channel analog comparator and operational amplifier integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 16 V, consuming a typical quiescent current of 1.4 μA for the combined op-amp and comparator functions. The device features rail-to-rail input capability with an extended common-mode range extending up to VCC + 5 V. Key electrical specifications include a maximum input offset voltage of 4 mV at 25°C, a gain-bandwidth product of 5.5 kHz, and a propagation delay time of 55 μs. It is housed in an 8-pin SOIC package and supports an industrial operating temperature range from -40°C to +125°C.

Feature Summary

• Combines a micro-power operational amplifier and an open-drain comparator in a single package to reduce board space and part counts.
• Features reverse battery protection allowing operation up to 18 V reverse voltage with minimal leakage current.
• Provides rail-to-rail input capability with an extended common-mode input range that exceeds the positive supply rail by 5 V.

Applications

• Battery-powered portable applications requiring low quiescent current
• Signal conditioning circuits utilizing mega-ohm resistors due to low input bias currents
• Systems compatible with Li-Ion batteries and micropower microcontrollers

Procurement Notes

Verify the specific ordering suffix 'ID' corresponds to the SOIC-8 surface-mount package and the industrial temperature grade (-40°C to +125°C). Confirm that the required performance parameters, such as the 4 mV maximum input offset voltage and 55 μs response time, align with the system design requirements before finalizing procurement.

Selection Notes

Select this component when a design requires both signal amplification and threshold detection within a single footprint. It is suitable for applications where power consumption is critical, specifically those needing sub-micropower operation. Ensure the load conditions and pull-up resistor values for the open-drain comparator output are compatible with the target logic levels.

Part Context

The TLV2302ID belongs to the TLV230x family of nanopower operational amplifiers and open-drain comparators. This series integrates high DC accuracy with extremely low power consumption, making it distinct from standard general-purpose amplifiers. The family includes variants like the TLV2304, which offers four channels in larger packages, while the TLV2302 provides two channels in compact form factors.
