What this single op amp brings to a signal chain
Input bias current is 2.5 pA, and input offset voltage is 250 µV — adequate for many sensor-conditioning and filter stages where you don't need a precision zero-drift amp.
The 1.8 V minimum supply lets this part run directly from a single Li-ion cell or a 1.8 V digital rail, while the 3.6 V maximum covers the common 3.3 V supply with margin. Rail-to-rail output means the signal can swing within millivolts of each rail, preserving dynamic range at low supply voltages. Each channel can source or sink 23 mA — enough to drive a reference input, a small relay coil, or a 50 Ω line with moderate swing.
