Product details

With a minimum supply of 2.7 V and maximum of 12.8 V, this op-amp runs from a single lithium-ion cell or a standard 5 V or 12 V rail. The rail-to-rail output maintains signal swing near the rails, which is useful when the ADC reference is tied to the same supply.

Housed in an 8-VSSOP (3.00 mm width) package, the LMH6643MM-NS fits tight PCB layouts but requires a fine-pitch soldering profile.

Because the part is RoHS non-compliant, buyers should confirm their assembly process can accept tin-lead finish if that is the variant on hand.

Frequently asked questions

What is the slew rate and bandwidth of LMH6643MM-NS?

The LMH6643MM-NS delivers a 135 V/µs slew rate and 130 MHz -3 dB bandwidth, making it suitable for high-speed signal conditioning such as video amplification or fast ADC driving.

What are the direct replacements or equivalents for LMH6643MM-NS?

A functional peer is the TLV9362IDDFR, a dual general-purpose op-amp with rail-to-rail output, but it operates at a much lower 10.6 MHz bandwidth and 25 V/µs slew rate — not a speed-equivalent replacement. For a higher-speed single-channel alternative, the THS4215DRBT offers 350 MHz and 970 V/µs but in a single-channel package. Neither is a pin-for-pin drop-in; evaluate the specific speed and channel-count requirements before substituting.
