Overview
The LMV7239QDBVRQ1 is a dual, low-voltage, rail-to-rail input and output operational amplifier designed for automotive applications. It features a bandwidth of 5 MHz and a slew rate of 4 V/µs, ensuring fast signal processing capabilities. The device operates from a single supply voltage ranging from 2.7 V to 5.5 V, with quiescent current consumption of 600 µA per amplifier. It includes short-circuit protection and functions reliably across an extended temperature range of -40°C to +125°C.
Feature Summary
- Rail-to-rail input and output capability maximizes dynamic range in low-voltage systems.
- Automotive qualification ensures reliability under harsh environmental conditions.
- Integrated short-circuit protection safeguards the device during fault conditions.
Applications
- Automotive sensor signal conditioning
- Battery management system monitoring
- Infotainment system audio pre-amplification
Procurement Notes
Verify the specific suffix DBVR indicates the VSSOP-8 package and tape-and-reel packaging configuration. Confirm the Q1 designation aligns with required automotive quality standards for your specific application tier. Ensure the operating voltage range matches your system power supply constraints before finalizing procurement.
Selection Notes
Select this component when rail-to-rail performance is critical within a 2.7 V to 5.5 V supply range. Consider its 5 MHz bandwidth for applications requiring moderate speed without excessive power consumption. Evaluate the VSSOP-8 package size against available PCB space constraints in compact automotive modules.
Part Context
This part belongs to Texas Instruments' LMV series of low-voltage operational amplifiers. The Q1 suffix denotes automotive-grade qualification, distinguishing it from standard commercial variants. It serves as a robust solution for analog signal processing in vehicles where space and power efficiency are paramount.
Replacement Considerations
Direct replacements include other LMV7239 variants with different package options such as LMV7239IDBVT or LMV7239IDR. Verify pin compatibility and electrical specifications match exactly when substituting to ensure circuit functionality remains unchanged.
