LinCMOS quad op-amp in 14-TSSOP — 1 MHz GBW, 45 nA input bias
It delivers a 1 MHz gain-bandwidth product and a 45 nA input bias current — two orders of magnitude lower than the standard bipolar LM324 — making it a direct drop-in for designs that need higher input impedance without changing the pinout.
1.5 mA supply — 375 µA per channel for the power budget
Total supply current is 1.5 mA across all four amplifiers, or roughly 375 µA per channel. That keeps the thermal rise low in the 14-TSSOP package and fits into a 3 V to 32 V supply span — single or dual rail.
The base product number LM324 is a long-running TI platform with broad second-source coverage across the industry.
It suits indoor equipment, benchtop instrumentation, appliance control boards, and office-environment PCBs. For industrial or automotive temperature ranges, the same LM324 function is available in -40°C to +125°C grades — check the -NOPB suffix variants if the ambient goes below freezing.
