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. Supply range from 1.8 V to 3.6 V. Industrial temperature grade -40°C to 85°C.
4 kHz GBP and 3 µA supply — what they mean for the BOM
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. The 13 mA output current per channel is enough to drive a reference input or a light load. Mounting is surface-mount only.
Lifecycle and compliance
The MAX4039EBL+T is listed as Active in production and ROHS3 compliant. No end-of-life notice or last-time-buy schedule is on record. For new designs, this part is available through independent distribution and quoted to order against an RFQ.
