Overview
The LF444CMX/NOPB is a quad low-power JFET input operational amplifier manufactured by Texas Instruments. It features four independent channels in an SOIC-14 surface-mount package. Key electrical specifications include a gain-bandwidth product of 1 MHz, a slew rate of 1 V/us, and an input bias current of 100 pA. The device operates within a supply voltage range of 6 V to 36 V, with a maximum dual supply of 18 V. It draws 600 uA of operating supply current per channel and provides 14 mA output current. Input offset voltage is specified at 10 mV, common-mode rejection ratio at 95 dB, and input voltage noise density at 35 nV/sqrt Hz.
Feature Summary
- Quad configuration integrating four independent low-power JFET input operational amplifiers.
Applications
- Audio signal processing circuits
- General-purpose analog signal conditioning
- Instrumentation front-end stages
Procurement Notes
Verify the specific suffix 'CMX' confirms the SOIC-14 surface-mount packaging and reel/cut-tape shipping format. Confirm the 'NOPB' designation indicates lead-free and RoHS compliance status as defined by Texas Instruments. Ensure the component matches the commercial temperature range of 0 C to +70 C for the intended application environment.
Selection Notes
Select this component when a quad amplifier topology is required with JFET input characteristics for low bias current. The SOIC-14 package suits automated surface-mount assembly processes. Consider the 1 MHz bandwidth and 1 V/us slew rate for moderate-speed applications. Verify that the 6 V minimum supply voltage aligns with the system power rails.
Part Context
This part belongs to the LF444 family of quad operational amplifiers from Texas Instruments. It serves as the surface-mount variant of the through-hole LF444CN, offering equivalent electrical performance in a compact SOIC-14 footprint. The device is designed for general-purpose analog applications requiring multiple amplifier channels.
Replacement Considerations
The LF444CN/NOPB is the direct through-hole pin-compatible alternative. Other quad JFET op-amps may require schematic and layout modifications due to differing pinouts or electrical parameters.
