Overview
The LMV7239M7X/NOPB is a dual, low-voltage, rail-to-rail input and output operational amplifier manufactured by Texas Instruments. Designed for single-supply operation, it features a wide bandwidth of 10 MHz and a slew rate of 15 V/µs. The device operates with supply voltages as low as 2.5 V, drawing a quiescent current of 400 µA per amplifier. It offers high output drive capability and maintains stability with capacitive loads up to 100 pF. The component is housed in an SOT-23-8 package, suitable for space-constrained portable applications requiring precision signal processing.
Feature Summary
- Rail-to-rail input and output capability enables full dynamic range utilization near supply rails.
- Low quiescent current consumption supports extended battery life in portable devices.
- Wide bandwidth and fast slew rate ensure accurate handling of high-frequency signals.
Applications
- Portable medical instrumentation
- Battery-powered sensor interfaces
- Active filters in communication systems
Procurement Notes
Verify the complete part number including suffixes such as 'M7X' and '/NOPB' to ensure correct packaging and lead-free compliance. Confirm that the supplier provides traceability documentation matching the manufacturer's specifications. Check for authenticity markers on the package to avoid counterfeit components. Ensure storage conditions align with moisture sensitivity level requirements before assembly.
Selection Notes
Select this component when rail-to-rail performance is required at low supply voltages. Consider its 400 µA quiescent current for power-sensitive designs. Verify that the SOT-23-8 package fits the PCB layout constraints. Compare bandwidth and slew rate against application signal frequencies to ensure adequate response time without oscillation.
Part Context
This device belongs to Texas Instruments' LMV series of low-voltage operational amplifiers. The series emphasizes low power consumption and compatibility with single-supply systems. The LMV7239 variant specifically provides dual-channel functionality within a compact footprint, distinguishing it from single-channel counterparts in the same family.
Replacement Considerations
Direct substitutes include other dual rail-to-rail op-amps from TI such as the LMV321 or LMV358 if pin compatibility allows. Verify electrical parameters like gain-bandwidth product and input offset voltage match application requirements before substitution.
FAQ
What is the maximum supply voltage for the LMV7239?
The maximum recommended supply voltage is 5.5 V.
Does the LMV7239 support capacitive loads?
Yes, it is stable with capacitive loads up to 100 pF.
