LMH6609MA/NOPB

Overview

The LMH6609MA/NOPB 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 or single supplies up to 12 V, with a typical operating supply current of 7 mA. Key electrical specifications 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 with current noise of 1.6 pA/√Hz. It functions within a temperature range of -40°C to +85°C.

Procurement Notes

Verify the specific suffix MA/NOPB against the manufacturer's latest datasheet to confirm package type and RoHS compliance status. Ensure the ordering part number matches the required pinout and environmental rating for your design. Cross-reference with official distributor catalogs to validate availability and authenticity before finalizing procurement plans.

Selection Notes

Select this component when a balance of moderate bandwidth and high output drive is required. It suits designs needing rail-to-rail output swing without the complexity of higher-gain-bandwidth products. Consider thermal management if operating near maximum current limits. Verify that the 150 MHz bandwidth meets system requirements without necessitating faster, more expensive alternatives.

Part Context

This device belongs to the LMH6609 family of high-speed operational amplifiers from Texas Instruments. It is part of a broader portfolio including variants like the LMH6609MF and LMH6609MDC, which differ primarily in packaging and manufacturing lot codes. The NOPB suffix indicates lead-free construction compliant with environmental standards. It serves as a specialized solution within the company's video and high-speed analog signal chain offerings.

Replacement Considerations

Direct replacements may include other single-channel high-speed op-amps with similar GBW and output current capabilities. Verify pin compatibility and electrical parameters such as slew rate and noise density. Consult the manufacturer's obsolescence notices for legacy packages like the MF variant.
