Quad op-amp with 18 MHz GBW and 25 V/µs slew — what the speed ratings mean for your signal chain
The LM6144BIN/NOPB: 18 MHz gain-bandwidth product and 25 V/µs slew rate support fast-settling analog signals. Total supply current for all four channels is 750 µA.
14-pin DIP — breadboard, retrofit, and high-vibration environments
The LM6144BIN/NOPB comes in a 14-DIP (0.300", 7.62 mm) through-hole package, with the supplier device package listed as 14-PDIP. This is the package you reach for when the board is going into a socketed prototype, a legacy product that needs a drop-in replacement, or an environment where through-hole retention beats surface-mount reliability — think industrial controllers, test equipment, or panel-mount modules where vibration and thermal cycling can stress solder joints. The DIP footprint also makes hand-rework straightforward for repair depots and MRO labs.
Temperature grade and supply — where it runs and what it drives
Each output channel can source or sink 22 mA, enough to drive a reference input, an ADC driver, or a modest analog meter movement. If your load demands more than 22 mA per channel, the part is not the right fit — look at a higher-drive amplifier or buffer the output.
For a procurement decision, this means the part can be qualified into a production BOM without scheduling an end-of-life migration. The through-hole DIP package is mature and widely stocked across the independent distribution channel.
