Micropower dual op-amp for battery and portable designs
The MAX9912EKA+T from Maxim Integrated is a dual general-purpose operational amplifier in an 8-pin SOT-23 package. It draws only 7 µA per channel of supply current, making it a strong fit for battery-operated instruments, portable medical devices, and sensor signal conditioning where every microamp counts. The rail-to-rail output swing lets it drive the full ADC input range on a single 1.8 V to 5.5 V supply without a negative rail.
200 kHz GBW and 0.1 V/µs slew rate — what they mean for your signal chain
The 200 kHz gain-bandwidth product sets the usable closed-loop bandwidth. The 0.1 V/µs slew rate limits large-signal response.
Input offset and bias — DC accuracy for sensor front-ends
Input offset voltage is 200 µV typical, and input bias current is 1 pA.
Package and temperature range
Housed in a SOT-23-8 package (supplier device package SOT-23-8), the MAX9912EKA+T is a surface-mount part suited for compact PCB layouts. The operating temperature range of -40°C to 85°C covers industrial and commercial environments — outdoor telecom cabinets, factory floor sensors, and portable equipment that sees temperature swings, but not extended under-hood automotive or downhole drilling.
Sourcing and lifecycle
The MAX9912EKA+T carries an Active product status and is ROHS3 compliant. For a BOM line that needs a low-power dual op-amp in a small footprint, this part is a low-risk, production-ready choice.
