Dual low-power op-amp for battery and sensor signal chains
The Maxim Integrated MAX4163EUA+ is a dual-channel general-purpose operational amplifier in an 8-uMAX/uSOP surface-mount package. It delivers a 200 kHz gain-bandwidth product with a rail-to-rail output stage, drawing just 25 µA per channel. The supply range spans 2.5 V to 10 V, making it suitable for single-supply battery-powered instrumentation, sensor conditioning, and portable audio paths where low quiescent current is a priority.
200 kHz GBW and 0.115 V/µs slew rate — what they mean for your signal chain
The 200 kHz gain-bandwidth product suits DC and low-frequency AC signals. The 0.115 V/µs slew rate limits large-signal bandwidth.
Rail-to-rail output and low supply current
The rail-to-rail output stage swings within millivolts of both supply rails. Each channel consumes 25 µA quiescent current, and output drive is rated at 15 mA per channel.
Package and temperature grade
Housed in an 8-uMAX/uSOP (3.00 mm width) package, the MAX4163EUA+ fits space-constrained PCBs. The -40°C to 85°C operating range covers industrial and outdoor telecom enclosures. Surface-mount assembly with standard reflow profiles applies; the tube shipping medium is typical for prototype and low-volume builds.
Lifecycle and sourcing reality
The MAX4163EUA+ carries an Active lifecycle status from Maxim Integrated (now part of Analog Devices). It is ROHS3 compliant.
