The 2.7 V to 7.5 V supply span covers single-rail voltages plus Li-ion battery range. Rail-to-rail output means the amplifier can swing within millivolts of either supply rail. The 5.5 mA output current per channel is adequate to drive a typical SAR ADC input or a reference buffer.
The MAX4198EUA+ is listed as Active with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect.
The -3 dB bandwidth is 175 kHz, with a slew rate of 0.07 V/µs. This suits low-frequency sensor and instrumentation applications.
Yes, the output type is rail-to-rail, allowing the output to swing close to both supply rails for maximum dynamic range at low voltages.
