Zero-drift precision amp with 5 MHz bandwidth
Its defining characteristic is an input offset voltage of 0.4 µV — typical for chopper-stabilized topologies — combined with a gain-bandwidth product of 5 MHz, which is notably higher than most zero-drift parts.
The 5 MHz GBW means this part can handle a 100 kHz signal with roughly 50× closed-loop gain, which is unusual for a zero-drift amp (many topologies trade bandwidth for drift performance). Supply current of 1.1 mA is modest; if the design is battery-powered, the 1.1 mA quiescent draw is worth comparing against the 50 mA output current capability when driving an ADC input or a long cable.
For designs requiring a long production horizon, this part is not at imminent risk of obsolescence.
