LMH6609MA

Overview

The LMH6609MA is a single-channel voltage feedback operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 150 MHz and a slew rate of 1.4 kV/µs. The device operates on dual supply voltages ranging from 3.3 V to 6 V, with a maximum total supply voltage of 12 V. Key electrical parameters include an input offset voltage of 3.5 mV, input bias current of 8 µA, and output current capability of 90 mA per channel. Common-mode rejection ratio is specified at 73 dB, while power supply rejection ratio reaches 67 dB. Input noise density is 3.1 nV/√Hz for voltage and 1.6 pA/√Hz for current. The component functions within a temperature range of -40°C to +85°C.

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and RoHS compliance status. Ensure the ordering part number matches the required SOIC-8 variant. Cross-reference datasheet revisions to validate parameter tolerances and operating temperature ranges before finalizing procurement specifications.

Selection Notes

Select this component when a single-channel amplifier with moderate bandwidth and high output drive is required. Compare input offset voltage and bias current requirements against application needs. Verify that the 150 MHz gain-bandwidth product meets the signal frequency constraints. Confirm that the SOIC-8 package fits the available PCB footprint and thermal management strategy.

Part Context

This device belongs to the LMH6609 series of high-speed operational amplifiers produced by Texas Instruments. It serves as a standalone solution for applications requiring fast transient response and significant output current. The family focuses on balancing speed with low noise performance in a compact surface-mount package.

Replacement Considerations

Direct substitutes include the LMH6609MF/NOPB, which offers identical electrical performance in a SOT-23-5 package. Verify pinout compatibility and thermal dissipation differences when transitioning between SOIC-8 and SOT-23-5 form factors.
