Dual-channel 90 kHz op amp in 10-MSOP
The MAX4243EUB+ is a general-purpose operational amplifier from Analog Devices' Beyond-the-Rails™ series, packing two independent rail-to-rail output stages into a 10-uMAX/uSOP package. Each channel draws 14 µA supply current, and the gain-bandwidth product is 90 kHz — suited for low-frequency signal conditioning where power budget is the binding constraint. Supply range spans 1.8 V to 5.5 V, so this part runs from a single Li-ion cell or a 3.3 V/5 V regulated rail without needing a split supply.
Parametric limits for the BOM line
Input offset voltage is 250 µV typical, and input bias current is 2 nA — adequate for sensor front-ends with source impedances in the tens of kΩ range. Slew rate is 0.04 V/µs; with a 90 kHz GBW, the full-power bandwidth into a 2.5 mA output load stays within the linear region for signals below a few kHz. Operating temperature range is -40°C to 85°C, covering industrial ambient conditions without requiring a heatsink or forced airflow.
Active lifecycle and compliance
The MAX4243EUB+ carries an Active product status from Analog Devices, with ROHS3 compliance — no end-of-life notice or last-time-buy window is open. Supplied in tube packaging (10-TFSOP/MSOP footprint), the part is surface-mount ready for standard reflow profiles.
