What this part is and where it fits
The Analog Devices MAX4199ESA+ is a single-channel differential amplifier in an 8-SOIC surface-mount package. It delivers rail-to-rail output swing while drawing only 45 µA supply current — a combination that suits battery-powered sensor front-ends, bridge transducers, and precision current-sense circuits where every microamp matters. The -3dB bandwidth of 45 kHz and slew rate of 0.1 V/µs confirm this is a low-frequency, precision part, not a high-speed buffer. Input offset voltage is trimmed to 10 µV, and the input bias current is 1 µA. Operating over -40°C to 85°C, it fits industrial and outdoor equipment that sees temperature swings.
Supply range and single-supply operation
The supply span runs from 2.7 V to 7.5 V. The rail-to-rail output maintains swing close to the rails at light loads — the output current capability is 5.5 mA per channel.
Sourcing and lifecycle
The MAX4199ESA+ carries an Active lifecycle status and is ROHS3 compliant. Sourced and quoted to order through independent distribution; availability and current pricing confirmed at quote time.
