The Analog Devices MAX4039EBL+T is a dual general-purpose operational amplifier with rail-to-rail output, packaged in a 9-ball WLP. It draws 3 µA supply current per amplifier and delivers a 4 kHz gain-bandwidth product. Industrial temperature grade -40°C to 85°C.
The 4 kHz gain-bandwidth product sets the usable frequency range for closed-loop gain. The 3 µA supply current per channel is the headline figure for battery-life budgeting. Input bias current is 1 pA. The 200 µV input offset voltage is typical for a low-power CMOS stage.
Package and layout considerations
The MAX4039EBL+T comes in a 9-ball WLP (Wafer-Level Package). The 9-WLP footprint means this is a machine-place-only part. Mounting is surface-mount only.
No end-of-life notice or last-time-buy schedule is on record.
