Overview
The LMV7239M5X/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 14 V/µs. The device operates with supply voltages as low as 2.5 V, drawing a quiescent current of 1.6 mA per channel. It offers high output drive capability and maintains stability with capacitive loads up to 100 pF. Packaged in a compact SOT-23-5 format, it supports applications requiring precision signal conditioning in portable electronics.
Feature Summary
- Rail-to-rail input and output capability enables full dynamic range utilization near supply rails
- Low voltage operation supports battery-powered systems with minimal power consumption
- High slew rate and bandwidth ensure fast transient response for video and audio signals
Applications
- Portable medical instrumentation
- Active filters in communication systems
- Video buffering and amplification
Procurement Notes
Verify the complete part number including the suffix NOPB to confirm lead-free status and RoHS compliance. Ensure the package type matches the SOT-23-5 footprint requirements on the target PCB. Confirm that the operating temperature range aligns with the specified industrial or commercial grades defined in the official datasheet before finalizing procurement orders.
Selection Notes
Select this component when rail-to-rail performance is critical at low supply voltages. It is suitable for designs requiring high speed and low power consumption simultaneously. Consider the small SOT-23-5 package size for space-constrained layouts. Verify thermal dissipation capabilities under maximum load conditions to ensure reliable operation within the specified temperature range.
Part Context
This device belongs to the LMV series of operational amplifiers from Texas Instruments, known for low-power and low-voltage specifications. The LMV7239 variant specifically provides dual-channel configuration with enhanced speed characteristics compared to standard general-purpose op-amps. It serves as a drop-in replacement for older bipolar technologies in modern low-voltage analog circuits.
Replacement Considerations
Check for direct pin-compatible alternatives such as the LMV7239IM5X/NOPB for different temperature grades. Verify electrical parameter overlaps if substituting with other dual op-amps from the LMV family. Ensure package compatibility remains consistent during cross-referencing.
