Description

The MAX44206 is a low-noise, low-distortion fully differential operational amplifier suitable for driving high-speed, high-resolution, 20-/18-/16-bit SAR ADCs, including the MAX11905 ADC family. Featuring a combination of wide 2.7V to 13.2V supply voltage range and wide 400MHz bandwidth, the MAX44206 is suitable for low-power, high-performance data acquisition systems.

The MAX44206 offers a VOCM input to adjust the output common-mode voltage, eliminating the need for a coupling transformer or AC-coupling capacitors. This adjustable output common-mode voltage allows the MAX44206 to match the input common-mode voltage range of the ADC following it. Shutdown mode consumes only 6.8µA and extends battery life in battery-powered applications or reduces average power in systems cycling between shutdown and periodic data readings.

The MAX44206 is available in an 8-pin µMAX® package and is specified for operation over the -40°C to +125°C temperature range.
