LMH6609MAX

Overview

The LMH6609MAX is a single-channel voltage feedback operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 260 MHz and a slew rate of 1.4 kV/us. The device operates on dual supply voltages ranging from 3.3 V to 6 V, with a maximum supply voltage of 12 V. Key electrical parameters include an input offset voltage of 2.5 mV, input bias current of 5 uA, and operating supply current of 7 mA per channel. It provides an output current of 90 mA per channel and a common-mode rejection ratio between 67 dB and 73 dB. The component is housed in an 8-SOIC package.

Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm pinout compatibility and thermal characteristics. Ensure the ordering code matches the exact package variant required for your PCB layout. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring high slew rates and moderate bandwidth within a compact SOIC package. Compare input offset voltage and noise specifications against alternative devices if precision DC performance is critical. Evaluate the supply current requirements against system power budgets to ensure efficient operation under continuous load conditions.

Part Context

This part belongs to the LMH6609 series of high-speed operational amplifiers. It shares architectural similarities with other members of the family but differs in packaging and specific electrical tolerances. The MAX suffix indicates a specific industrial or commercial grade variant within the broader product line, distinct from tape-and-reel or die configurations.

Replacement Considerations

Direct replacements include LMH6609MA/NOPB and LMH6609MF/NOPB. Verify pin compatibility and thermal dissipation capabilities before substituting. Check for any differences in gain stability or noise performance that may affect circuit behavior.
