MAX44205
180MHz, Low-Noise, Low-Distortion,
Fully Differential Op Amp/SAR ADC Driver
General Description
The MAX44205 is a low-noise, low-distortion fully differ-
ential 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 MAX44205 is suitable for low-power, high-
performance data acquisition systems.
The MAX44205 offers a VOCM input to adjust the out-
put common-mode voltage, eliminating the need for a
coupling transformer or AC-coupling capacitors. This
adjustable output common-mode voltage allows the
MAX44205 to match the input common-mode voltage
range of the ADC following it. A proprietary output voltage
clamping solution ensures that the buffer output does not
violate the ADC’s maximum input voltage range, even if
the MAX44205’s supply rails are higher than the ADC’s
full-scale range. 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 MAX44205 is available in 12-pin, 3mm x 3mm, TQFN
and 10-pin μMAX® packages and is specified for opera-
tion over the -40°C to +125°C temperature range.
