1.4 µA supply, 1 µV offset — the micropower precision trade-off
The LTC2063IS5#TRMPBF is a single-channel zero-drift operational amplifier from Analog Devices that draws 1.4 µA of supply current and has a 1 µV typical input offset voltage.
Where the 20 kHz GBW sets the boundary
A 20 kHz gain-bandwidth product means the open-loop gain drops to unity at 20 kHz. The 0.0035 V/µs slew rate reinforces the same message: the output cannot track fast edges.
Zero-drift architecture and the 1 µV offset floor
Chopper-stabilized (zero-drift) topology continuously nulls the input offset voltage, holding it near 1 µV over temperature and time. That eliminates the need for system-level calibration in many designs. The input bias current is 3 pA, which suits high-impedance sources like pH probes or photodiode amplifiers without adding a noticeable voltage error across the source resistance. The output can source or sink 51 mA, enough to drive an ADC input or a small relay directly.
