LMH6574MAX/NOPB

Analog Switches - Special Purpose Overview

The LMH6574MAX/NOPB is a quad, low-voltage, rail-to-rail input and output operational amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 2.7V to 3.0V and features a CMOS technology node. Key electrical specifications include an input offset voltage (Vos) of 7.5 mV, an input bias current (Ib) of 20 fA, and a typical operating supply current of 160 uA per channel. The device provides a channel output current capability of 6 mA, with a common-mode rejection ratio (CMRR) of 60 dB and a power supply rejection ratio (PSRR) of 60 dB. It is housed in a 14-SOIC surface-mount package and supports an industrial operating temperature range from -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• Quad-channel architecture providing four independent amplifiers in a single package for space-constrained designs.
• Rail-to-rail input and output capabilities allowing signal swing across the full supply voltage range.
• Ultra-low input bias current specification suitable for high-impedance sensor interfaces.

Analog Switches - Special Purpose Applications

• Low-voltage analog signal conditioning circuits
• Portable battery-powered instrumentation systems
• Multiplexed data acquisition front-ends

Analog Switches - Special Purpose Procurement Notes

Verify component authenticity through authorized distribution channels due to potential counterfeit risks. Confirm that the specific suffix matches the required package and temperature grade. Ensure compliance with RoHS directives if environmental regulations apply to the final assembly. Cross-reference datasheet revisions to confirm pinout compatibility before integration into existing PCB layouts.

Analog Switches - Special Purpose Selection Notes

Select this component when multiple low-voltage amplification stages are required within a strict 3V power budget. Evaluate the trade-off between the 160 uA quiescent current and the 6 mA drive capability against system power constraints. Consider the 7.5 mV offset voltage limit for precision requirements and verify that the SOIC-14 footprint aligns with available board real estate.

Analog Switches - Special Purpose Part Context

This part belongs to the LMH6574 family of low-voltage operational amplifiers designed for portable applications. It shares functional similarities with other quad op-amps in the series but is distinguished by its specific 2.7V to 3.0V operating window and CMOS construction. The MAX/NOPB designation indicates a lead-free, halogen-free variant in a standard industrial temperature range package.

Analog Switches - Special Purpose Replacement Considerations

Direct substitutes may include other quad rail-to-rail op-amps from Texas Instruments such as the LMC6574 series, provided the supply voltage and package constraints are met. Verify that alternative components maintain compatible input bias currents and output drive capabilities for the specific application load.
