Product details

18 MHz GBW, 25 V/µs slew — a quad op-amp that pulls double duty

It delivers an 18 MHz gain-bandwidth product and a 25 V/µs slew rate while drawing just 750 µA per channel — a combination that suits it for signal conditioning in industrial control, motor-drive feedback paths, and multi-channel data acquisition where both bandwidth and power budget matter. The rail-to-rail output stage lets it swing close to the supply rails, useful when driving ADCs or low-voltage logic directly.

That means stable supply for new designs and no last-time-buy clock ticking.

Frequently asked questions

Does LM6144AIMX/NOPB have a similar part with a smaller package?

The LM6144AIMX/NOPB is only offered in the 14-SOIC package. For a smaller footprint, consider a dual op-amp like the TLV9362IDDFR (2-channel, 10.6 MHz, 25 V/µs, 14-pin TSSOP) or a single-channel part such as the TLV9351IDCKR (3.5 MHz, 20 V/µs, SC-70). Neither is a drop-in replacement — you would need to adjust the board layout and channel count.
