Dual op-amp for precision single-supply signal chains
The MAX4092ASA+T is a dual-channel general-purpose operational amplifier from Analog Devices, designed for low-power, single-supply applications where rail-to-rail output swing preserves dynamic range at low voltages.
DC precision and input characteristics for sensor front-ends
Input bias current is 20 nA typical. Driving a 10 kΩ source, this bias current creates a 200 µV voltage drop across the source resistance — negligible for most circuits but worth derating if the source impedance exceeds 100 kΩ. The rail-to-rail output stage means the output can swing within millivolts of the supply rails, preserving the usable signal range in a 3.3 V system where every 100 mV of headroom matters.
